The XD-Series callbox is programmable to operate as an analog FM two way radio or as an 
NXDN digital voice two way radio. This allows user to transition to digital voice as needed. The 
NXDN capability is contained in a piggy back board that connects perpendicular to the main 
board. The XD-Series callbox is available in both the standard model high visibility green 
enclosure, and in the -BLK model black enclosure. 
The model number appears on the serial label located on the back of the XD-Series Callbox 
enclosure.  
VHF radios are designed to operate within the 15 MHz band between factory standard 150 to 
165 MHz. 
UHF radios are designed to operate within the 20 MHz band between factory standard 450 to 
470 MHz.  
Advanced Features available with the XD-Series models include 2-Tone, DTMF, Selcall and 
NXDN Decode, Voice Messages, Analog Companding, Sensor Input, and a Relay Switch 
Closure. 
NXDN digital Features are based on RAN and ID codes and perform similar functions as the 
analog addressing modes. The Ritron programmer will aid in PC set up of these features. Manual 
set up of these features can be seen in under 
HOW TO FIELD PROGRAM NXDN 
FEATURES 
The Power supply to the XD callbox can be three internal D cells or an external 8 to 12 VDC input or both. It is important to use 
new good quality D cells. See “Applying power to the XD-Series Callbox”. 
OPTIONAL ACCESSORY EQUIPMENT 
Several options are available for the Ritron XD-Series Callbox.  These options, individually, or in combination with one another can 
greatly enhance the functionality of the callbox as well as the overall communication system.  Available options include:

ALLBOX
 ...........................................................  
The XD-Series Callbox is a 2-way radio transceiver used to communicate directly with portable, mobile and stationary analog FM or 
NXDN digital radios; or through radio repeaters with Ritron PC Programming software.  Each callbox is equipped with the following 
features or capabilities. 
  Field Programming.  Field programming allows you to quickly program your radio in the field without the need for a PC 
programmer. Each radio can be field programmed to one of 27 VHF or 114 UHF channel table frequencies, and one of 50 QC 
or 104 DQC interference eliminator codes. 
  154 Interference Eliminator Codes.  Quiet Call (QC) and Digital Quiet Call (DQC) codes can be programmed to eliminate 
other radio users not in your workgroup. For compatibility, new radios should be programmed with the same codes.(analog 
only) 
  Volume Level.  Field programmable or PC programmable to 20 – 100% volume level. 
  Normal or High Microphone Gain.  Field and PC programmable to fixed or AGCed microphone gain. 
  Battery Powered.  The XD-Series Callbox can be powered by 3 Alkaline or Ni-MH D-cell batteries for 700mW transmit power. 
D-cell batteries can operate the radio for up to one year or 8,000 three second transmissions. 
  Low Battery Alert.  The callbox will transmit an Alert Tone or voice message at the end of each transmission when the 
batteries approach end-of-life. This allows sufficient time for you to replace the batteries and assure uninterrupted service. 
  External Power 8 to12 VDC Capable.  The XD-Series Callbox can be powered by an external 8 to 12 VDC source. This 
method of powering the callbox allows the radio to remain ON at all times, like an intercom. Automatic Turn Off must be 
DISABLED via Field or PC programming for Intercom operation. 
  External Power Fail Alert. This feature can be enabled via Field or PC programming. The callbox will transmit an Alert Tone or 
voice message if it detects loss of external DC power. The radio automatically continues to transmit an Alert Tone once every 
hour (unless programmed for Automatic Turn Off) until external DC is restored or the batteries are depleted. 
   High/Low Power Output.  When powered by External 8 to12VDC the XD-Series callboxes will be transmitting at high power 
output (2W).  When battery powered by 3 D cells the XD-Series callbox operates in Low power (700mW) mode exclusively. If 
low power is desired for the external DC power radio it will have to be reprogrammed setting high power to desired level. 
 “Automatic Turn-Off” or “Intercom” Operation.  The XD-Series Callbox can operate in the standard “Automatic Turn-Off” 
mode (Factory Default), where the radio is normally OFF until the Call Button is pressed, or can be Field or PC programmed for 
“Intercom” operation where the radio is always ON. See “External Power Power Capable” feature above. 
  DTMF or Selcall ANI.  Field or PC Programmable for 3-7 digit DTMF or Selcall ANI codes which are transmitted at the 
beginning of each message for radio identification. (analog only) 
  Companded Audio.  The radio can be Field or PC programmed to ENABLE or DISABLE audio companding. Companding will 
compress transmit audio before sending it, and expand receive audio before it is heard on the speaker to reduce the 
background noise common in radio communications. Do not use microphone in AGC mode when using companding. (analog 
only) 
  Voice Messages.  You can record custom voice messages that are played back during normal Callbox operation.  Messages 
include Greeting, Voice Alert, Sensor status, Battery status, and external DC Power Fail.  
  Listen In.  Allows remote activation of the transmitter when a unique 2-Tone, DTMF or Selcall code is received in analog mode. 
Field or PC programmable to 2-Tone, DTMF or Selcall codes and 4 different Listen In transmit times. In digital an NXDN ID 
code can be used.   
  Sensor Turn-On.  When operating the Callbox with Automatic Turn-Off enabled, the unit can be configured to turn itself ON 
any time the Sensor Input is pulled LOW (ground).  This allows an external switch closure to activate the Callbox. The callbox 
will remain on as long as the switch is closed. 
  2-Tone, Selcall or DTMF Decoding.  The Callbox can be programmed to decode unique 2-tone, Selcall or DTMF codes for 
selective signaling of the Callbox, “Listen In” remote activation of the transmitter, or Switch Output activation in GateGuard® 
applications. 
  Relay Switch Output.  The switch output is a simple 3-Amp relay contact closure that can be used to OPEN and CLOSE a 
gate, switch on a light, sound an alarm or any other application where remote control of an ON/OFF switch is required. The 
callbox can be programmed to OPEN and CLOSE the Switch Output with a 2-tone, Selcall, or DTMF code in alalog or NXDN 
ID code in digital. 
  Sensor Input.  The Callbox can be configured to send a warning tone or a pre-recorded voice message when a change in the 
Sensor Input is detected. The Sensor Input will respond to an OPEN or CLOSED switch. The unit must already be on to 
respond to a switch opening.

 ..............................................  
PLEASE NOTE THE FOLLOWING WITH REGARD TO RF EXPOSURE FOR THIS PRODUCT: 
This product generates radio frequency (RF) energy when the PTT button on the front of the unit is depressed. This product has 
been evaluated for compliance with the maximum permissible exposure limits for RF energy at the maximum power rating of the 
unit. At the 20 cm (8 inches) minimum expected separation distance and greater, the maximum RF exposure is at or below the 
General Population/Uncontrolled limits. Operator should stay at least  20 cm (8 inches) from call box. External antennas have not 
been tested for compliance and may or may not meet the exposure limits at the distances given. Higher gain antennas are capable 
of generating higher fields in the strongest part of their field and would, therefore, require a greater separation from the  antenna. 
They can be mounted higher than the call box which will increase the operator’s separation from the antenna. This product is not to 
be used by the general public in an uncontrolled environment unless compliance with the Uncontrolled/General Population limits for 
RF exposure can be assured. 
To limit exposure to RF energy to levels below the limit, please observe the following: 
•  DO NOT activate the transmitter when not actually wishing to transmit. 
•  When transmitting, make certain that the distance limits for the particular model in use are observed. 
•  DO NOT allow children to operate the radio. 
When used as directed, this series of radios is designed to comply with the FCC’s RF exposure limits for “Uncontrolled/General 
Population”.  In addition, they are designed to comply with the following Standards and Guidelines: 
•   United States Federal Communications Commission, Code of Federal Regulations; 47 CFR §§ 2 sub-part J.  
•   American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992.

 ......................  
The XD-Series Callbox Factory Default setting is with Automatic Turn-Off ENABLED. This means the callbox is OFF and will not 
receive a call until the callbox first initiates a call. 
In Automatic Turn Off mode the callbox automatically shuts off whenever there is “no activity” for a programmed number 
of seconds (10 second default). Activity keeping it awake is either the ON/PTT button activation or a received call.  
To Initiate a Call 
Press and hold the ON/PTT Button. Listen for the “beep”, then, begin speaking. For best communication, the caller should be 3 feet 
or less from the callbox. The callbox can be programmed to send a unique CALL TONE to alert radio equipped personnel. This 
CALL TONE will also be heard at the callbox. 
To Receive a Call 
1.  When you have finished speaking, release the ON/PTT Button. 
2.  Any reply will be heard through the callbox speaker. If a call is not received within 10 seconds of releasing the ON/PTT Button 
and there is no activity on the channel, the callbox will sound a low double tone and turn-off automatically. This automatic turn-
off feature is designed to conserve battery life. 
Operation Notes 
The XD-Series Callbox must be powered internally with Alkaline or Ni-MH batteries ONLY. The standard unit comes with a 3 D cell 
holder. Ni-MH low self discharge (LSD) batteries are available on line which offer a great rechargeable option. Alternatively, an 
external 8 to 12 VDC power supply can be used, order Ritron model RPS-1B 110 VAC to 12 VDC cube power supply with ferrite 
clamp. When using an external supply, the internal D cell Alkaline batteries can be used as back-up. See page 5. The unit will work 
with external voltages down to about 6 VDC but the power output will shift to the low power 700mW level when the voltage is too 
low. 
Low Battery Alert 
The callbox will transmit an Alert Tone at the end of each transmission when the batteries approach end-of-life. This allows sufficient 
time for you to replace the batteries and assure uninterrupted service.  On XD-Series Callboxes the LOW battery alert tone can be 
replaced by a LOW battery voice message.

The XD-Series Callbox may be powered by:  
 3 internal D-cell batteries for 700mW operation 
 An external 8 to 12 VDC source for 2W operation (unit functions as low as 5 VDC with reduced RF power output) 
Powering the callbox from internal batteries will allow for an installation that does not require wiring to an external source of power. 
Powering the callbox by an external source could, with programming, allow the unit to remain ON, like an intercom*.  
To extend battery life, one of two battery saver options may also be used in the analog mode. See “POWER MANAGEMENT OPTIONS” 
on page 6. With this mode, Automatic Turn Off must be DISABLED via Field or PC Programming. 
Using Internal Batteries 
Batteries may be installed in the internal battery holder for a no trenching, no wires required installation. If internal batteries are 
used, a LOW battery alert tone or voice message will be transmitted when the battery voltage drops below a programmed value. 
The LOW battery tone notifies personnel that the batteries should be replaced.  On XD-Series Callboxes the LOW battery alert tone 
can be replaced by a LOW battery voice message. 
IMPORTANT! When installing D-cell batteries be sure all are the same, and are all new cells. DO NOT mix new and used batteries. 
Alkaline D cells are readily available in department stores. Alternatively, low self-discharge (LSD) nickel-metal hydride rechargeable 
can be ordered online. The advantage of the LSD NiMH is they can be reused, have a lower internal resistance and sustain good 
voltage over the battery life. If operating at very cold temperatures NiMH may be considered. A smart charger will also be needed 
with the rechargeable. The XD call box can draw about 0.7 Amp when transmitting so battery health is important. 
XD-Series Battery Installation 
1.  Using the T-25 Torx bit included with the radio, remove the 
four corner screws on the plastic interior case and separate 
the case halves. 
2.  Disconnect the power cable connecting the battery holder to 
the radio. 
3.  Install 3 new D-cell batteries into the battery holder. Be sure 
to observe polarity as indicated. 
4. Re-connect the power cable. 
5.  Secure the plastic case halves with the corner screws.  Be 
sure power cable is in the area below the battery holder and 
is not pinched between the case halves. 
External Antenna Connector and Antenna Jumper Settings 
The  XD-Series  Callbox  is  equipped  with  an  Antenna Selector 
Jumper that will  route  all  incoming  and  outgoing  radio  signals  
to  either the built-in  internal  antenna,  or to the SMB RF Test / 
External Antenna connector.  
The  XD-Series  Callbox  comes  from  the  factory  with  the  
Antenna Selector Jumper  in  the  “INTERNAL ANTENNA”  
position  for operation  with  the  built-in internal  antenna.  
Important - For testing  through  the  SMB RF  connector,  OR 
for connection  to  an optional external  antenna (optional cable 
also required), you must remove  the  Antenna  Selector Jumper 
PJ201. 
For mounting an external antenna the Ritron six inch coaxial 
adapter (Ritron # 60201125) can be used to go from the SMB to 
a hole in the case. Care must be taken while drilling so as not to 
crack the case.

Using External +12 VDC Power with Battery Back-up 
Note:   An additional hole, strain relief, and conduit will need to be installed into the callbox. 
The unit may be powered by an external source of 8 to 12 VDC. This 
source should be filtered, with minimum noise and hum, and capable of 
supplying at least 1 Ampere.  
Factory Default programming of the callbox is optimized for battery 
power operation.  The External 8 to 12 VDC Power Fail Alert option is 
NOT ENABLED. 
It is recommended that if an external source of power is used, that the 
internal batteries be installed as a back-up against loss of power. If this 
option is chosen, we recommend that the “External Power Fail Alert” 
feature be ENABLED via Field or PC programming. 
How the Callbox will operate: 
If External 8 to 12 VDC Power Fail Alert Feature is NOT ENABLED: 
  LOW battery detection can only occur when the external voltage is removed or failed. 
  Radio will only check for LOW battery or DEAD battery condition when the radio is ON. 
  If LOW battery is detected, a single tone Alert or voice message will be transmitted at the end of the transmission.  
  Radio does NOT automatically transmit a LOW battery tone alert or voice message. The callbox must be ON and Alert or voice 
message is only sent at the end of a transmission.  
  If DEAD battery is detected, the radio ceases all operation. A DEAD battery tone is heard on the callbox speaker and the radio 
will turn OFF. 
If External 8 to 12 VDC Power Fail Alert Feature is ENABLED: 
  Radio always checks for External voltage when the radio is ON. If loss of external voltage is detected while the radio is in 
standby: a single Alert Tone or voice message will be transmitted immediately.  
  If loss of external voltage is detected while the radio is in receive: a single Alert Tone will be transmitted after the received 
message is complete.  
  If loss of external voltage is detected while the radio is in transmit: a single Alert Tone will be transmitted at the end of the 
transmission.  
  Once loss of external voltage is detected and the Alert Tone is transmitted, the radio will automatically send the Alert Tone once 
every hour until external voltage is restored or the batteries are exhausted. If radio is set for Automatic Turn-Off (default setting) 
this hourly alert will NOT occur. 
  If Dead battery is detected the radio ceases all operation, a DEAD battery tone is heard on the callbox speaker and the radio will 
turn OFF. 
Using External 8 to 12 VDC Power without Battery Back-up 
The Ritron RQX callbox can be programmed for always-on operation by disabling the Automatic Turn-Off option.  This is 
accomplished using the RQX PC Programmer, or through Field Programming.  Once Automatic Turn-Off is disabled, the user 
simply turns on the RQX by pressing the front panel PTT button and it will remain on as long as power is applied.  If power to the 
callbox is lost then restored, the user must press the front panel PTT to restart the radio.  For externally powered callboxes, battery 
backup is one method of keeping the radio on if the primary external power is lost.   
For users that do not want to “restart” the callbox after a power loss, the callbox can be modified to automatically restart 
after a power loss. By loading 15 k ohm in R628 the external power supply will automatically turn on if there is an input. Also 
PJ602 must be in the “sensor turn-on” mode with the sensor input (pin 2 of PJ601) tied to ground. This configuration will also turn 
the internal battery on if the external power fails. R628 need not be loaded if only internal batteries are used. 
For details or questions about this modification contact Ritron at 1-800-872-1872  
Important considerations before applying this modification: 
  The Automatic Turn-Off option must be disabled. 
  When Automatic Turn-Off is disabled the unit will consume the largest amount of current, but is always ready to instantly receive 
messages. This mode should only be considered if an external source of power is available. If internal batteries only are used, the 
radio would work only a few days. 
 
The callbox receiver will always be on.  All radio communication on the programmed frequency and tone will be heard over the 
RQX callbox.
For External 
+12VDC power, 
order Ritron model 
RPS-EXPO 110 
VAC to 12 VDC 
cube supply.

 ........................................................... 
Automatic Turn-Off ............................................................................................................................... (Field or PC Programmable) 
In this mode, the callbox will automatically turn itself off after a programmed period of no activity (no transmissions made and no 
calls received) has elapsed. Once the unit has turned itself off, it can only be turned back on by depressing the ON/PTT Button. 
The programmed period of no activity necessary before the unit turns itself off is called the RQX Reset Time. RQX Reset Time and 
Automatic Turn-Off can both be Field programmed, or PC programmed by the factory or your Ritron dealer via the Ritron RQX 
Series PC Programmer.  Automatic Turn-Off mode is the factory default mode for power management with an RQX Reset Time of 
10 seconds. 
Analog Radio Battery Saver .....................................................................................................................(PC Programmable Only) 
This mode, only available for the analog radio, is similar to the Automatic Turn-Off mode except that the unit does NOT turn itself off 
after the RQX Reset Time has elapsed. Instead it reverts to a mode where the unit goes to sleep and periodically wakes up to test 
for receive activity on the channel. The Sleep Period (called Battery Saver Sleep Time) can be set using the Ritron RQX Series PC 
Programmer to between 0.5 and 8 seconds. Longer sleep times result in better battery life, but increase the chances that activity on 
the channel may be missed. The unit will come out of this mode when activity is detected during the wake-up period or if the 
ON/PTT button is pressed. The Automatic Turn-Off and Battery Saver modes cannot be used together. 
Neither “Automatic Turn-Off” nor “Battery Saver” Used .................................................................. (Field or PC Programmable) 
If neither Automatic Turn-Off nor Battery Saver are used the unit will consume the largest amount of current, about 90 mA, but is 
always ready to instantly receive messages. This mode should only be considered if an external source of power is available (see 
“Using External 8 to 12 VDC Power with Battery Back-up” on page 5). 
NXDN Radio Power Consumption ……………………………………………………………………………… (Automatic) 
“ON with sync”: When the NXDN radio is actively looking for a sync word in receive mode it consumes about 80 mA. The digital 
receiver IC is looking for the NXDN preamble and sync word and once found will wake up the NXDN processing board. Once awake 
while decoding voice the radio draws about 270 mA with a low audio volume setting. When the received signal disappears the unit’s 
consumption goes back to about 80 mA. 
“Always ON”: NXDN board is always ON consuming about 250 mA in RX mode. 
 If Automatic Turn-Off is enable the current will drop to zero at the expiration of the reset timer. If Automatic Turn-Off is not enabled 
the unit will continue drawing 80 mA in “ON with sync” or 250 mA in ”Always ON” mode. 
Sensor Turn-On ...................................................................................................................................................................................  
When operating a XD-Series Callbox with Automatic Turn-Off enabled, the unit can be configured to turn itself ON any time the 
Sensor Input is pulled LOW (ground).  This allows an external switch closure to activate the Callbox. When the switch closure is 
detected the Callbox will turn on and automatically transmit the Sensor On alert or Sensor ON voice message.  The Callbox is then 
in normal operating mode and will automatically turn itself off after a programmed period of no activity as described in the Automatic 
Turn-Off topic in this section. For Sensor Turn-On operation the Sensor Turn-On jumper must be placed into the “Turn-On” position.  
Refer to FIG-1 below for correct placement of the jumper.  If the Sensor Input is not used the jumper placement has no effect on 
Callbox operation.

 ........................................................................................  
For special applications, it is desirable to program the XD-Series Callbox for 2-Tone, DTMF or Selcall decode (receive) operation. 
The user is able to field program the radio for one of the 9 pre-determined tone pairs specified in Table 4 on page 15, or for any 3-7 
digit DTMF or Selcall sequence. The 2-Tone codes correspond to field programmable 2-Tone encode (transmit) codes available in 
other RITRON portable and base radios.  
Programming the radio for 2-Tone, DTMF or Selcall decode operation MUST BE DONE IN THE FOLLOWING ORDER! 
1.  Program the desired Operation code (Refer to Table 4).  This will delete any previous Primary or Secondary Decode code 
programming. 
2.  Program the desired 2-Tone, DTMF or Selcall Primary Decode code (Refer to Table 4).  An “E” error indication will appear 
on the display if the programmed Operation code does not require a Primary Decode code. 
3.  If required, program the desired 2-Tone, DTMF or Selcall Secondary Decode code (Refer to Table 4). An “E” error 
indication will appear on the display if the programmed Operation code does not require a Secondary Decode code. 
  The Secondary Decode code must be the same type as the Primary Decode code. For example, if the Primary 
Decode code was set for DTMF, the Secondary Decode code must also be DTMF. 
  The Secondary Decode code cannot be the same as the Primary Decode code. 
  If using DTMF or Selcall, the Primary and Secondary Decode codes must have the same number of digits.     
4.  Program the desired Features code (Refer to Table 4). 
In the following example we will program an RQX-417NX for paging operation with 2-Tone Decode Code 94 frequencies of 389.0 
and 669.9 Hz, and for Listen In operation with 2-Tone Decode Code 95 frequencies of 410.8 and 707.3 Hz.  The Listen In time will 
be set for 10 seconds. 
  1.  Loosen the (4) captive screws in the front corners of the case and separate the case front from the case back, leaving the 
batteries connected to the radio.  Make sure the unit has batteries installed.  The voltage of the batteries must be greater 
than 3.3 VDC to program properly. 
   2.  Press and release the ON/PTT button on the front of the unit to turn the radio on. 
    3.  Press and HOLD the Program Button (See FIG-2 on page 7 for location). A "P" will appear on the program display as you 
enter program mode and the radio will beep rapidly. Release the program button after the beeping has stopped. The radio 
will emit a triple beep indicating that the radio is in program mode and a hyphen will appear on the program display.   
 404  4.  Refer to Table 4 on page 15 to determine the three-digit Operation code for Paging and Listen In operation. 
  5.  Click the Program button until the program display shows the Program Code “C”.  Pause—the radio will sound a low tone 
and show a hyphen across the center of the display to indicate that it is ready to accept the next programming code. 
    6.  Enter the 1st digit of the Operation Code by clicking the Program button until the program display shows the desired 
number. Pause—the radio will sound a low tone and show a hyphen across the center of the display to indicate that it is 
ready to accept the next digit. 
   7.  Enter the 2nd digit of the Operation Code by clicking the Program button until the program display shows the desired 
number.  Pause—the radio sounds a low tone and will show a hyphen across the center of the display to indicate that it is 
ready to accept the next digit. 
  8.  Enter the 3rd digit of the Operation Code by clicking the Program button until the program display shows the desired 
number.  Pause—the radio sounds a low tone and will show a hyphen across the center of the display to indicate that it is 
ready to accept the next digit. 
 9.  Press and release the ON/PTT button to save your programming. A triple beep will sound to indicate that programming 
was successful and a hyphen will appear on the program display.  The radio is now ready for another program entry. 
 94 10.  Refer to Table 4 on page 15 to determine the two-digit code for 2-tone decode on 389.0 and 669.9 Hz. 
  11.  Click the Program button until the program display shows the Program Code “C”.  Pause—the radio will sound a low tone 
and show a hyphen across the center of the display to indicate that it is ready to accept a 2-digit 2-Tone code from Table 4, 
or a 3 to 7-digit DTMF or Selcall decode sequence. 
  12.  FOR DTMF CODES ONLY – Enter a “1” using the Program button. Pause—the radio will sound a low tone and show a 
hyphen across the center of the display to indicate that it is ready to accept the next digit. 
  13.  FOR SELCALL CODES ONLY – Enter a “2” using the Program button. Pause—the radio will sound a low tone and show a 
hyphen across the center of the display to indicate that it is ready to accept the next digit. 
    14.  Enter the 1st digit of the 2-Tone code (or 1st digit of the DTMF or Selcall code) by clicking the Program button until the 
program display shows the desired number. Pause—the radio will sound a low tone and show a hyphen across the center 
of the display to indicate that it is ready to accept the next digit. 
   15.  Enter the 2nd digit of the 2-Tone code (or 2nd digit of the DTMF or Selcall code) by clicking the Program button until the 
program display shows the desired number.  Pause—the radio sounds a low tone and will show a hyphen across the 
center of the display to indicate that it is ready to accept the next digit. 
   15.  FOR DTMF OR SELCALL CODES ONLY – Enter the 3rd digit of the DTMF or Selcall decode sequence. Pause—the radio 
sounds a low tone and will show a hyphen across the center of the display to indicate that it is ready to accept the next 
digit.  Continue entering up to seven digits.

The XD-Series Callbox can be field programmed for a number of advanced features. Refer to Table 5 for the two or three digit 
codes available for field programming.  In our example we will program an RQX-417 for an RQX Reset Time of 30 seconds.  
   1.  Refer to Table 5 to determine the two or three-digit feature code and write it down. 
2.  Loosen the (4) screws in the front corners of the case.  
   3.  Separate the case front from the case back, leaving the batteries connected to the radio.  Make sure the 
unit has batteries installed. 
    NOTE:  The voltage of the batteries must be greater than 3.3 VDC to program properly. 
4.  Press and release the ON/PTT button on the front of the unit to turn the radio on. 
   5.  Press and HOLD the Program Button (See FIG-2 on page 7 for location). A "P" will appear on the program 
display as you enter program mode and the radio will beep rapidly. 
6.  Release the program button after the beeping has stopped. The radio will emit a triple beep indicating that 
the radio is in program mode and a hyphen will appear on the program display.   
 7. Click the Program button until the program display shows the Program Code “A”.  Pause—the radio will 
sound a low tone and show a hyphen across the center of the display to indicate that it is ready to accept a 
2-digit or a 3-digit Feature code. 
   8.  Enter the 1st digit of the feature code by clicking the Program button until the program display shows the 
desired number. Pause—the radio will sound a low tone and show a hyphen across the center of the 
display to indicate that it is ready to accept the next digit. 
   9.  Enter the 2nd digit of the feature code (if necessary) by clicking the Program button until the program 
display shows the desired number. Pause—the radio sounds a low tone and will show a hyphen across the 
center of the display to indicate that it is ready to accept the next digit. 
   10.  Enter the 3rd digit of the feature code (if necessary) by clicking the Program button until the program display 
shows the desired number. Pause—the radio sounds a low tone and will show a hyphen across the center 
of the display to indicate that it is ready to accept the next digit. 
   11.  Press and release the ON/PTT button to save your programming. A triple beep will sound to indicate that 
programming was successful and a hyphen will appear on the program display.  The radio is now ready for 
another program entry. 
    NOTE:  An error tone will sound if you attempt to save an incorrect code, an "E" will appear on the display.  
Check the digits you are attempting to enter, then re-enter. 
   12.  Once you have made your final program entry, press the ON/PTT button a final time to turn the radio off.  
Turn the radio back on for normal operation.

 ...............................  
The XD-Series Callbox has a variety of programmable features that determine how your callbox operates. Some of these features 
can be Field Programmed (FP) by you without using special tools, while other features can only be Programmed (PC) with a PC 
and RQX Series PC Programmer RQX-PCPS-1.0 or higher. Contact your Ritron dealer or the factory for details. 
Glossary of Terms  
Intercom Mode   The Automatic Turn-Off feature has been disabled and the Callbox is able to receive calls at any time. 
Sleep (analog)  If Automatic Turn-Off is DISABLED and Battery Saver is ENABLED the Callbox will go into a low current Sleep 
Time when it is not being used, waking up periodically to check for a received message. Pressing the ON/PTT 
button will wake-up the radio immediately. 
Wake-Up (analog)  When Battery Saver is ENABLED and the Callbox has entered the low current Sleep state, the radio will wake-
up periodically to check for a received message. The Sleep Time is set by the Battery Saver Sleep Time. 
No Activity Time   A continuous period of time where the Callbox is not sending or receiving a call.

Feature  Key  Description 
Field Programming Enable    This option is ENABLED as the Factory Default setting. This permits all Field 
Programmable features (FP) to be field programmed by you. If DISABLED, the features 
can only be programmed using special Ritron PC Programming software. 
Send Call Tone  The Factory Default setting has the Call Tone feature ON (refer to “HOW TO FIELD PROGRAM 
FEATURE CODES” on page 19). The callbox can be programmed to transmit a Call Tone if 
the Reset Time has expired and the ON/PTT button is pressed. This will alert system users 
that the call is originating from the callbox. 
Speaker Volume   The Factory Default setting is medium volume. Field Programming or PC Programming 
allows any volume level between 20 – 100%. A lower speaker volume reduces audio 
distortion and provides a more natural sound. For best performance, do not set the volume 
any higher than is necessary for your application. 
Automatic Turn-Off   This feature is ENABLED as the Factory Default setting. The callbox will turn OFF when the 
RQX Reset Time has expired. The Reset Time is a pre-programmed amount of time of “no 
activity” (no calls transmitted, no calls received) before the callbox turns OFF in order to 
conserve battery life. The callbox can be turned back ON when the ON/PTT button is 
pressed. This is the recommended mode of operation for all battery only powered 
applications. 
    If Automatic Turn-OFF is NOT selected the callbox does NOT completely turn OFF, but 
remains in the Intercom mode, allowing the callbox to receive calls at any time.  
    Operating the callbox with Automatic Turn-Off DISABLED significantly increases battery 
drain, and is therefore NOT recommended for battery only powered applications. Battery life 
can be increased using the Battery Saver Enable feature detailed in this section. 
RQX Reset Time   Set from the factory for 10 seconds, the RQX Reset Time can be Field Programmed to 9 
different times ranging from 5 seconds to 4 minutes, and PC programmed for 5-255 
seconds.  A shorter RQX Reset Time will result in increased battery life. In standard 
Automatic Turn-Off operation a longer RQX Reset Time will allow more time for a response 
before the Callbox turns off. 
    RQX Reset Time defines the Inactivity Time allowed before the Callbox: 
    • Turns Off if Automatic Turn-Off is ENABLED. 
    • Enters Battery Saver mode if Battery Saver is ENABLED. 
    • Resets 2-Tone, DTMF or Selcall Paging Decode. 
    • Automatically opens the Switch output. 
 KEY:   Feature is Field Programmable.

Feature  Key  Description 
Battery Saver Enable    When the XD-Series Callbox is programmed to operate with Automatic Turn-Off disabled, 
Battery Saver can increase battery life in both internal and external battery powered 
applications. 
    With Battery Saver Enable, the callbox will periodically Wake-Up and listen for a received 
signal before returning to a low current Sleep state. The time between Wake-Up states can 
be PC programmed between 0.5 - 8 seconds with the Battery Saver Sleep Time setting. A 
longer time between Wake-Up states will result in increased battery life. 
    The callbox immediately leaves Battery Saver mode any time the ON/PTT Button is 
pressed or a signal is received, and will not return to Battery Saver until the period of no 
activity exceeds the RQX Reset Time. 
Power Fail Alert Tone  By selecting the +12 VDC Power Fail Alert Tone feature the callbox will look for a loss of the 
+12 VDC power source. The callbox will immediately transmit an Alert Tone to notify 
personnel that the +12 VDC source has been lost and is now operating on battery back-up. 
The callbox will transmit an Alert Tone once every hour until the +12 VDC power source is 
restored or until the back-up batteries are exhausted. Even if this feature is NOT selected, it 
will always revert to Back-up Battery power, see page 5 for details. 
Microphone Gain  The Microphone can be placed in FIXED or AGC gain mode. The AGC mode generaly 
works well for applications where the speakers voice level can varry greatly. However is 
quite periods of speech background noise will rise due to increasing gain. In high 
background noise applications, using the fixed gain mode with a lower number programmed 
in the text box will decrease background noise transmitted by the Callbox. The caller will 
need to get closer to the callbox when speaking but overall background noise will be less. 
The fixed gain is programmable from 0 to 255. 
Listen In  Listen In allows remote activation of the Callbox transmitter for a programmed period of 
time when the correct 2-Tone, DTMF or Selcall or NXDN code is decoded.   
    This feature,  turned OFF by default, can be Field Programmed to 4 different transmit times 
ranging from 5-30 seconds and PC programmed for 1-255 seconds.   
    The 2-Tone, DTMF or Selcall or NXDN Decode Code required to activate the feature can 
be Field Programmed from the 9 different 2-Tone Decode Codes in Table 4, 3-7 digit 
DTMF, Selcall codes or 5 digit NXDN ID, or PC programmed for any 2-Tone frequency pair 
between 300-1500 Hz. 
Busy Channel TX Inhibit  With this feature enabled the Callbox cannot transmit when there is a received signal.  A 
“busy signal” will be heard on the Callbox speaker when the PTT is pressed and a received 
signal is present.  Busy Channel TX Inhibit is disabled from the factory. 
Sensor/Contact Closure Input (not programmed)  The Callbox will send a warning tone when a change in the Sensor Input is detected. The 
Sensor Input will respond to an OPEN or CLOSED switch. 
Transmit Beep Enable  This feature is turned on from the factory to provide a short beep in the Callbox speaker any 
time the ON/PTT button is pressed. This assures the Callbox user that the radio has turned 
on and is ready to transmit their message. With this feature disabled the Callbox will only 
beep when the radio is first turned on. 
RX Courtesy Beep Enable  In high noise environments it is sometimes difficult to determine when a received message 
has ended. With the RX Courtesy Beep enabled the Callbox will sound a short beep on the 
speaker at the end of each received transmission. 
TX Time Out Time  Set from the factory for 60 seconds, the TX Time Out Time can be PC programmed for 1-
255 seconds. This sets the length of time the Callbox can transmit continuously. If the 
ON/PTT button is held down longer then the TX Time Out Time will allow, the radio will stop 
transmitting and a “Busy Signal” will be heard in the speaker until the button is released. 
DTMF or Selcall ANI  The RQX can be programmed to send a 3-7 digit DTMF or Selcall ANI code at the 
beginning of each transmission for radio identification. (analog only) 
Companding  The Factory Default setting for Companding is OFF (NOT selected). The radio can be 
programmed to ENABLE or DISABLE audio companding. Companding will compress 
transmit audio before sending it, and expand receive audio before it is heard on the speaker 
to reduce the background noise common in radio communications. (analog only)

ROGRAMMING
 .............................................  
The XD-Series Callbox can be Field or PC programmed by the factory or by your Ritron dealer to operate as a two-way intercom.  
When operating as an intercom the Automatic Turn-Off must be DISABLED so that the radio will remain ON in a “intercom” mode. 
The callbox can receive a call from another radio at any time. The higher current requirements of Intercom operation make it 
undesirable in battery powered only installations. It is recommended that you power the callbox using +12 VDC capability. See page 
5. 
Required Radio Programming: 
Automatic Turn-Off....................................................................................................................... (Field or PC Programmable) 
This feature must be DISABLED via Field or PC programming for the callbox to remain ON at all times. 
Other Programmable Features to Consider: 
Battery Saver ...................................................................................................... (PC Programmable)  
Battery Saver can be used to increase battery life in battery powered applications. With Battery Saver enabled, the callbox will 
periodically “wake-up” and listen for a received signal before returning to a low current “sleep” mode. The Sleep Time can be 
PC programmed between 0.5 - 8 seconds. A longer sleep time will result in increased battery life, but may result in missed 
calls. 
Busy Channel TX Inhibit .............................................................................................................. (Field or PC Programmable) 
If ENABLED this feature prevents you from talking over someone else on the same channel even if they are using a different 
tone code. The radio will beep a series of long, low tones that sounds like a “busy signal” when you press the ON/PTT button.

Programming for Selective Calling: 
2-Tone, DTMF or Selcall or NXDN Paging Decode ..................................................................... (Field or PC Programmable) 
This allows selective calling to a XD-Series Callbox in a radio system where there is more than one Callbox. When the Callbox 
is programmed for 2-tone, DTMF or Selcall or NXDN decode in Intercom (Always-On) mode it will sound an alert tone on the 
Callbox speaker, similar to a telephone ring tone, whenever the 2-tone, DTMF or Selcall or NXDN page has been successfully 
decoded. This will alert any users in the immediate area that there is an incoming call on the Callbox. 
Ring Tone ....................................................................................................................................... (Field or PC Programmable) 
Ring Tone must be set to sound the alert tone on the Callbox speaker when a 2-Tone, DTMF or Selcall or NXDN Page is 
successfully decoded.  Ring Tone is enabled from the factory. 
2-Tone Monitor Trip .................................................................................................................................... (PC Programmable) 
This can be set when used with 2-Tone. DTMF or Selcall decode to allow the Callbox to hear all radio traffic on the channel 
after it has successfully decoded the correct code, regardless of QC or DQC programming.   
  Normal conversation will follow after the 2-tone, DTMF or Selcall code is decoded.    
  If the ON/PTT button is pressed the Callbox returns to QC or DQC decode operation.   
  The radio will automatically reset back to 2-tone, DTMF or Selcall decode after the RQX Reset Time has expired. 
Switch Output Programming: 
Switch on When Called ................................................................................................................. (Field or PC Programmable) 
This will close the internal Switch Output whenever the radio receives a call after an Inactivity Time that exceeds the RQX 
Reset Time. The switch will remain closed until the ON/PTT button is pressed or the RQX Reset Time expires. The Switch 
Output could be used to turn on a light or activate an alarm to notify users in the area that an incoming call was present.

The XD-Series switch output is a simple 3-Amp relay contact closure that can be used to OPEN and CLOSE a gate, switch on a 
light, sound an alarm or any other application where remote control of an ON/OFF switch is required. The XD-Series Callbox can be 
programmed to OPEN and CLOSE the Switch Output when one of the following programmed conditions is met.  
The XD-Series Callbox can be programmed to alternately OPEN and CLOSE the switch using a single 2-tone, DTMF or Selcall or 
NXDN code, or can be PC programmed for separate OPEN and CLOSE codes. Field programming offers 3-7 digit DTMF or Selcall 
or NXDN codes, or nine 2-tone codes that correspond to field programmable 2-tone codes available in select RITRON portable and 
base radios. NXDN IDs can range from 1 to 65519. 
No Switch........................................................................................................................................... (Field or PC Programmable) 
Select this option for no switch operation. 
Switch On When Called ............................................................................................................... (Field or PC Programmable) 
With this option selected the switch will CLOSE when the Callbox first receives a call. The switch will remain CLOSED until the 
ON/PTT button is pressed or the RQX Reset Time expires. This option is not applicable if the Callbox is programmed for Automatic 
Turn-Off. 
Switch On When Callbox in Use  .............................................................................................. (Field or PC Programmable) 
This option will CLOSE the switch when the Callbox first sends or receives a call. The switch will remain closed until the RQX Reset 
Time expires, which also turns the radio off if it is programmed for Automatic Turn-Off. 
Switch On When Active with Turn-Off Code ...................................................................................... (Field or PC Programmable) 
This option operates the same as Switch On When Callbox in Use with the added ability to OPEN the switch when a unique 2-Tone, 
DTMF or Selcall or NXDN Turn-Off Code is received. Unlike the Switch On When Callbox in Use feature, the switch will not OPEN 
when the RQX Reset Time expires unless the Callbox is programmed for Automatic Turn-Off. See “2-TONE, DTMF OR SELCALL 
DECODE (RECEIVE) SETTINGS” on page 26 for details on programming a Turn-Off code. 
GateGuard® – Momentary for  1  sec. ..................................................................................... (Field or PC Programmable) 
With this option selected the switch will momentarily CLOSE when a unique 2-Tone, DTMF or Selcall code is received.  The switch 
will remain CLOSED for the programmed period of time, programmable for 1-255 seconds. See “2-TONE, DTMF OR SELCALL DECODE 
(RECEIVE) SETTINGS” on page 26 for details on programming a 2-Tone, DTMF or Selcall Decode Code. 
GateGuard® – Toggle .................................................................................................................... (Field or PC Programmable) 
With this option selected the switch will alternately OPEN and CLOSE when it receives a unique 2-Tone, DTMF or Selcall code. 
After the code is received the Callbox will transmit a SINGLE BEEP if the switch has been OPENED and a DOUBLE BEEP if the 
switch has been CLOSED. The switch will open when the Callbox turns off if it is programmed for Automatic Turn-Off. See “2-TONE, 
DTMF OR SELCALL DECODE (RECEIVE) SETTINGS” on page 26 for details on programming a 2-Tone, DTMF or Selcall Decode Code. 
GateGuard® – On Code / Off Code .......................................................................................... (Field or PC Programmable) 
When this option is selected the switch will CLOSE when a unique 2-Tone, DTMF or Selcall or NXDN code is received, and OPEN 
when a 2-Tone, DTMF, Selcall or NXDN Turn-Off code is received. The switch will OPEN when the Callbox turns off if it is 
programmed for Automatic Turn-Off.  See “2-TONE, DTMF OR SELCALL DECODE (RECEIVE) SETTINGS” on page 26 for details on

With the XD-Series Callbox 2-Tone, DTMF, Selcall or NXDN decode can be used to selectively call the Callbox in a system where 
multiple radios operate on a single frequency. Alternatively, 2-Tone, DTMF, Selcall or NXDN decode can also be used to operate 
the Switch Output built into every XD-Series Callbox.  
When the radio is programmed for 2-Tone, DTMF or Selcall Paging Decode code, no call will be heard unless the code has been 
successfully decoded or the ON/PTT button has been pressed. After decoding, normal 2-way conversation is possible without the 
need for the 2-tone, DTMF or Selcall code.  Paging Decode is automatically reset when the RQX Reset Time expires. 
When the XD-Series Callbox is programmed for Switch Output or Listen In operation with 2-Tone, DTMF, Selcall or NXDN decode, 
regular voice communication is unaffected by the 2-tone, DTMF, Selcall or NXDN code. If a Switch Output Option is selected that 
uses 2-tone, DTMF or Selcall decode it cannot be used for Paging Decode. 
NOTICE 
When the callbox is programmed for 2-Tone Decode operation, it is recommended that you do NOT use QC Tone 
Codes greater than “23” (146.2 Hz).
2-Tone Table #  ............................................................................................ (Field or PC Programmable) 
The XD-Series Callbox comes equipped with 9 pre-determined 2-Tone codes that correspond to table codes that certain RITRON 
portable and base radios can send. Use of the 2-Tone Table codes allows programming without the need for the PC programmer.

You can custom program the 1st tone of the 2-tone code to any frequency between 300-1500 Hz. The 1st tone must be decoded for 
the programmed period of time before the radio looks for the 2nd tone.  The factory setting for decode time is 1 second. 
2nd Tone decoded for  1   sec.  ................................................................................ (PC Programmable) 
You can custom program the 2nd tone of the 2-tone code to any frequency between 300-1500 Hz.The 2nd tone must be decoded 
for the programmed period of time after the 1st tone has been decoded. The factory setting for decode time is 1 second. 
All Call decoded for  4   sec.  ................................................................................... (PC Programmable) 
With 2-Tone All Call enabled you can custom program an All Call tone to any frequency between 300-1500 Hz. The All Call tone 
must be decoded for the programmed period of time.  All Call can also be achieved with a unique DTMF or Selcall code. All Call is 
not enabled as received from the factory. 
Ring Tone Enable ......................................................................................... (Field or PC Programmable) 
With this feature enabled the Callbox will sound a ring signal in the speaker, similar to a telephone ring, any time the 2-Tone, DTMF,  
Selcall or NXDN code, Group Call or All Call code is decoded.  Ring Tone is enabled from the factory. 
Transpond Enable ........................................................................................ (Field or PC Programmable) 
Transpond transmits a tone after a 2-Tone, DTMF, Selcall or NXDN code, Group Call or All Call code has been received to alert the 
calling radio that the code was successfully decoded. Transpond is enabled from the factory. 
Group Call Decode ................................................................................................. (PC Programmable) 
When this option is set, 2-tone decode is achieved if the radio receives the 1st tone for the programmed All Call time. If this option is 
selected the All Call time must be longer than the 1st Tone time or the Callbox will always decode on the 1st tone, ignoring the 2nd 
tone altogether. Group Call can also be achieved with a unique DTMF or Selcall code. Group Call is not enabled as received from 
the factory. 
Monitor Trip ........................................................................................................... (PC Programmable) 
With this option selected the Callbox will be in carrier squelch mode any time a 2-Tone, DTMF, Selcall or NXDN code is decoded, 
regardless of any QC or DQC code programmed in the radio. The radio reverts back to QC or DQC tone decode if the ON/PTT 
button is pressed and reverts back to 2-tone, DTMF, Selcall or NXDN decode after the RQX Reset Time has expired.  Monitor Trip 
is not enabled from the factory. 
2-Tone, DTMF or Selcall Decode with Subtone  .............................................. (Field or PC Programmable) 
With 2-Tone, DTMF or Selcall Decode with Subtone enabled, the Callbox will not decode codes unless the correct subtone is also 
present.  2-Tone, DTMF or Selcall Decode with Subtone is not enabled from the factory. 
Turn-Off Code .............................................................................................. (Field or PC Programmable) 
In certain Switch Output applications a separate 2-Tone, DTMF or Selcall Turn-Off Code is required. This code cannot be the same 
as the 2-Tone, DTMF or Selcall Decode Code.

The XD-Series Callbox is equipped to use pre-recorded voice messages that notify radio system users when specific events occur.  These 
unique voice messages are recorded and stored on the Callbox, and automatically played back when the associated event occurs.  The 
XD-Series Callbox supports 6 different message events and comes from the factory with no messages recorded.   
To activate any of the 6 event messages simply record the voice message per the instructions in this manual.  The recorded message can 
be played back for your review and re-recorded if necessary.  You can erase any event message individually if you decide not to utilize that 
message. 
Greeting Message 
The Greeting Message is played on the RQX Callbox speaker when the push-to-talk button is first pressed.  This message is used to give 
the Callbox user instruction on how to proceed.  A typical message might be ‘Welcome to our facility.  An attendant will be with you shortly.”   
The Greeting Message: 
  Is played on the RQX Callbox speaker only when the push-to-talk button is first pressed. 
  Will be re-played every time the push-to-talk button is pressed until the Callbox is answered. 
  Is not transmitted. 
  Can be up to 12 seconds long. 
Voice Alert Message 
The Voice Alert Message is transmitted automatically by the Callbox when the push-to-talk button is first pressed.  Often used with the Call 
Tone feature, this message alerts radio system users that the Callbox has been activated.  Typical messages might be “South delivery 
entrance”, “Curbside Lane 4” or “Main gate”.  
The Voice Alert Message: 
  Is transmitted automatically by the Callbox when the push-to-talk button is first pressed.   
  Will be re-transmitted every time the push-to-talk button is pressed until the Callbox is answered.  
  Is transmitted after the Greeting Message has played on the speaker.  If the Greeting Message is not used, the Voice Alert Message will 
be heard on the speaker. 
  Will not be sent if the radio channel is busy when Busy Channel TX Inhibit feature has been enabled.  Instead, it will wait for the channel 
to clear before transmitting. 
  Will be automatically re-transmitted periodically until the Callbox is answered if the Callbox has been programmed with the Automatic ID 
Re-Send feature. 
  Will be sent after the Call Tone if the Call Tone feature is enabled. 
  Is automatically sent ahead of Sensor Detect or Low Battery/Power Fail messages. 
  Can be up to 4 seconds long. 
Power Fail Message 
With the “External +12V Power Fail Alert” enabled the Power Fail Message is automatically transmitted when loss of external power 
is detected on the Callbox. It will not be sent if the radio channel is busy, but instead will wait for the channel to clear before 
transmitting. Also, the message alert is appended to the existing transmission, and the Call Tone and Voice Alert Message will only 
be sent if it was a part of the existing transmission. A typical message might be “Power failure”. The Voice Alert Message is sent 
immediately before the Power Fail/ Low Battery Message, so a typical transmission might be “South delivery entrance” followed by “Power 
Failure”. Make sure the message is recorded and enabled under the “Message” menu. 
.  
Low Battery Message 
The Low Battery Message is appended to a transmission when low voltage is detected on the 3 D cell battery pack on the Callbox provided 
the message is recorded and enabled. A typical message might be “Low battery” 
Sensor Detect On Message 
The Sensor Detect On Message is automatically transmitted when the Sensor Input is pulled low.  Depending on the sensor used, a typical 
message might be “Door open”, “Motion detected” or “Vehicle present”.  The Voice Alert Message is sent immediately before the Sensor 
Detect On Message, so a typical transmission might be “South delivery entrance” followed by “Door open”.

 .....................................................................  
The RQX XD-Series Callbox can automatically re-send the Call Tone, Voice Alert Message, and DTMF or Selcall ANI a programmed 
number of times when a call is not immediately answered.  This allows the Callbox to periodically repeat the Voice Alert Message without 
further input from the Callbox user.  The periodic rate is determined by the RQX Reset Time.  
Following is an example of Automatic ID Re-Send programming and its effect: 
The Callbox is field programmed for: 
 Greeting Message “Welcome to Ritron, someone will be with you shortly” 
 Voice Alert Message “Main Entrance” 
  Call Tone ON 
  Automatic Turn-Off enabled 
 RQX Reset Time of 20 seconds 
  Automatic ID Re-Send set to 1 
Here is how it will operate: 
 A guest presses the Callbox On/PTT button and the Greeting Message “Welcome to Ritron, someone will be with you shortly” is heard 
on the Callbox speaker. 
  If the radio channel is not being used the Callbox will transmit the Call Tone, followed by the Voice Alert Message “Main Entrance.”  This 
will be heard by all system radio users, but not heard on the Callbox speaker. 
  If the Callbox is not answered within 20 seconds (RQX Reset Time) the Call Tone and Voice Alert Message will be re-transmitted 
(Automatic ID Re-Send). 
  If the Callbox is again not answered within 20 seconds (RQX Reset Time) it will turn off (if Automatic Turn-Off is enabled). 
  If the Callbox On/PTT button is pressed again at any time before it is answered the entire process described above is re-started. 
  If the Callbox is answered before it automatically turns off the Callbox operates as normal 2-way radio communication with no messages 
or Call Tone. 
Using Automatic ID Re-Send to Extend RQX Reset Time 
A Voice Alert Message does not have to be used to enjoy the benefits of Automatic ID Re-Send.  This feature can also be used to extend 
the RQX Reset Time whenever the Callbox On/PTT button is 1st pressed, providing radio users additional time to respond to the Callbox. 
For example, if the Callbox is programmed for an RQX Reset Time of 10 seconds and Automatic ID Re-Send of 5, the Callbox will remain 
ON for 60 seconds (RQX Reset Time plus RQX Reset Time multiplied by number of Automatic ID Re-Send) after the On/PTT button is 1st 
pressed instead of 10 seconds (RQX Reset Time).  Once the Callbox has been answered it will turn off after 10 seconds (RQX Reset Time) 
of inactivity.

 ...................................................................  
The XD-Series Callbox can be field programmed for basic GateGuard® operation, or PC programmed to suit your unique 
requirements. The instructions in this section apply only to Field Programmable features. If PC programming software has 
been used to set 2-Tone, DTMF, Selcall or NXDN decode (receive) or other optional GateGuard® features, operation may not be as 
described here. 
Follow these steps to program the XD-Series Callbox for GateGuard® operation (analog only): 
1.  Program the frequency and tone codes per the “HOW TO FIELD PROGRAM FREQUENCY & TONE CODES” instructions on page 11. 
2.  Program the 2-Tone, DTMF or Selcall Decode (Receive) code per the “HOW TO FIELD PROGRAM 2-TONE, DTMF OR SELCALL 
DECODE (RECEIVE) OPERATION” instructions on page 13. 
3.  Program the callbox for GateGuard® Momentary Operation per the “HOW TO FIELD PROGRAM 2-TONE, DTMF OR SELCALL 
DECODE (RECEIVE) OPERATION”  instructions on page 13. 
The XD-Series Callbox will now operate in GateGuard® mode as follows: 
  The Callbox will be in “Automatic Turn-Off” mode.  The ON/PTT button must first be pressed as described in “OPERATING THE 
XD-SERIES CALLBOX WITH FACTORY DEFAULT SETTINGS” section on page 3 before normal two-way communications can be 
established. 
  If the Callbox does not send or receive a signal for more than 10 seconds the Callbox will automatically turn off. The ON/PTT 
button must be pressed to turn the Callbox back on and receive a call.  
  When the Callbox receives and decodes the correct 2-Tone, DTMF or Selcall Decode code the Callbox Switch Output will 
momentarily CLOSE the switch for 1 second. The Callbox will also automatically transmit a confirmation tone back to the senders 
radio notifying them that the correct 2-tone, DTMF or Selcall code has been decoded at the XD-Series Callbox.

Automatic Turn-Off........................................................................................................................ (Field or PC Programmable) 
This is ENABLED as the Factory Default setting. The callbox will turn OFF when the RQX Reset Time has expired. The Reset Time 
is a pre-programmed amount of time of “no activity” (no calls transmitted, no calls received) before the callbox turns OFF in order to 
conserve battery life. The callbox can be turned back ON when the ON/PTT button is pressed. This is the recommended mode of 
operation for all battery only powered applications. 
If Automatic Turn-Off is NOT selected the callbox does NOT completely turn OFF, but remains in the Intercom mode, allowing the 
callbox to receive calls at any time.  
Operating the callbox with Automatic Turn-Off DISABLED significantly increases battery drain, and is therefore NOT recommended 
for battery only powered applications. Battery life can be increased using the Battery Saver Enable feature detailed in this section. 
RQX Reset Time .................................................................................................................................... (Field or PC Programmable) 
This is set from the factory for 10 seconds, but can be Field Programmed to 9 different times ranging from 5 seconds to 4 minutes, 
and PC programmed for 5-255 seconds.  A shorter RQX Reset Time will result in increased battery life. In standard Automatic Turn-
Off operation a longer inactivity timer will allow more time for a response before the callbox turns OFF. 
Battery Saver Enable ......................................................................................................................................... (PC Programmable)  
When the XD-Series Callbox is programmed to operate with Automatic Turn-Off DISABLED, Battery Saver can increase battery life 
in both internal or external battery powered applications.   
With Battery Saver Enable, the callbox will periodically Wake-Up and listen for a received signal before returning to a low current 
Sleep mode. The sleep time can be PC programmed between 0.5 - 8 seconds with the Battery Saver Sleep Time setting. A longer 
sleep time will result in increased battery life, but may result in missed calls.

External +12 VDC Power Fail Alert Tone ............................................................................................ (PC or Field Programmable) 
By selecting the +12 VDC Power Fail Alert Tone feature the callbox will look for a loss of the +12 VDC power source. The callbox 
will immediately transmit an Alert Tone to notify personnel that the +12 VDC source has been lost and is now operating on battery 
back-up. The callbox will transmit an Alert Tone once every hour until the +12 VDC power source is restored or until the back-up 
batteries are exhausted. Even if this feature is NOT selected, it will always revert to Back-up Battery power, see page 5 for details. 
NOTE:  In applications where external power is available, we recommend using the RPS-EXPO Cube Power Supply. See page 5 
for details. 
Send Call Tone ....................................................................................................................................... (Field or PC Programmable) 
The Factory Default setting has the Call Tone feature ON (refer to “HOW TO FIELD PROGRAM FEATURE CODES” on page 18). The 
callbox can be programmed to transmit a Call Tone if the Reset Time has expired and the ON/PTT button is pressed. This will alert 
system users that the call is originating from the callbox. 
Ring Tone .............................................................................................................................................. (Field or PC Programmable) 
This will sound an alert tone on the callbox speaker, similar to a telephone ring tone, whenever the correct 2-Tone, DTMF, Selcall  
or NXDN code has been successfully decoded. This feature is used to alert the Callbox user that the gate is being opened or 
closed.  Ring Tone is enabled from the factory. 
GateGuard® – Toggle ........................................................................................................................... (Field or PC Programmable) 
Will alternately open and close the Switch Output when it receives a unique 2-Tone, DTMF, Selcall  or NXDN code.  After the 2-tone 
decode (receive) code is received the callbox will transmit a single beep if the switch has been opened and a double beep if the 
switch has been closed. The switch will open when the callbox turns off if it is programmed for Automatic Turn-Off. 
GateGuard® On Code / Off Code ......................................................................................................... (Field or PC Programmable) 
This operation allows programming of separate ON and OFF 2-Tone, DTMF, Selcall or NXDN Decode (receive) codes.  The XD-
Series Callbox will CLOSE the Switch Output upon receiving the ON code, and OPEN the Switch Output upon receiving the OFF 
code.  
When reading out the radio programming as described in the “HOW TO READOUT CURRENT RADIO FREQUENCY & TONE CODES” section, 
the ON code will be displayed. 
Relay Polarity 
The relay switch output can be set for a normally-open or normally-closed condition depending on the position of the Relay Polarity 
Jumper. (See FIG-1) 
Sensor/Contact Closure Input  
The Sensor Input will detect a logic level and transmit an Alert tone when a change in logic level is detected. Separate alert tones 
are used for OPEN (logic level high) tone and CLOSED (logic level low) tone.  Additionally, the Sensor Input can be used to turn on 
the RQX Callbox with the Sensor Input Jumper in place. 
Busy Channel TX Inhibit ...................................................................................................................... (Field or PC Programmable) 
This will not allow you to transmit when another user is already transmitting on your radio frequency, even if they are using a 
different tone code. The radio will beep a series of long, low tones (like a busy signal) while the ON/PTT button is held down.

EATURES
XD callboxes which are fitted with an NXDN board can be programmed to send NXDN codes such as RAN codes and ID codes. 
Each callbox must have its unique subscriber unit ID (SUID) and operate its squelch based on either receiving the proper RAN code 
or individual or group ID code. It can also be required to have both the correct RAN code and individual or group ID code. The “all 
call” code (65535) can be considered a group call code. Also, the radio’s relay can be closed or opened when an open ID or closed 
ID is received. A summary of the program codes and features is shown below in table 8.

 n1    2  RX RAN codes (0-63 for repeater access code) 
 n2    2  TX RAN codes (0-63 for repeater access code) 
 n3    1-5  SUID (unique ID transmitted by callbox) 
 n4    1-5  Group ID (defines “group” the callbox is in and will hear messages) 
 n5    1-5  primary control ID code 
 n6    1-5  secondary control ID code 
 n71    1-5  Individual Destination ID (individual ID the radio will call) 
 n72    1-5  Group Destination ID (group ID the radio will call) 
IDs must be in the 1 to 65519 range. An “n” will set the code and an “r” read out the code. 
To read out the code key in “r” followed by a 1 through 7, hit PTT and the code will be displayed digit by digit. For example, if a 
group destination ID of 1000 is set, to read out the destination ID key in “r” then “7” and hit PTT. The display will show “2” then 
“01000”. Here “2” indicates a group and “1” would mean individual ID. 
The NXDN radio will use whatever channel is set up in the regular channel programming section. Digital narrowband (9600 bps) or 
super-narrowband (4800 bps) mode can be selected and programmed. Set up for Digital super-narrow band follows: 
 1.  Loosen the (4) captive screws in the front corners of the case. These screws are captive to the housing; to 
prevent damaging them, DO NOT remove the screws from the housing. 
   3.  Separate the case front from the case back, leaving the batteries connected to the radio.  Make sure the 
unit has batteries installed. 
    NOTE:  The voltage of the batteries must be greater than 3.3 VDC to program properly. 
4.  Press and release the ON/PTT button on the front of the unit to turn the radio on. 
   5.  Press and HOLD the Program Button (See FIG-2 on page 7 for location). A "P" will appear on the program 
display as you enter program mode and the radio will beep rapidly. 
 6.  Release the program button after the beeping has stopped. The radio will emit a triple beep indicating that 
the radio is in program mode and a hyphen will appear on the program display.   
 7. Click the Program button until the program display shows the Program Code “A”.  Pause—the radio will 
sound a low tone and show a hyphen across the center of the display to indicate that it is ready to accept a 
2-digit RF channel mode. 
 8. FOR Digital super-narrowband – Click the Program button until the program display shows a “9”.   
 9. FOR Digital super-narrowband – Click the Program button until the program display shows a “4”. 
    10.  Press and release the ON/PTT button to save your programming. A triple beep will sound to indicate that 
programming was successful and a hyphen will appear on the program display.  The radio is now ready for 
another program entry. 
    NOTE:  An error tone will sound if you attempt to save an incorrect code, an "E" will appear on the display.  
Check the digits you are attempting to enter, then re-enter. 
   11.  Once you have made your final program entry, press the ON/PTT button a final time to turn the radio off.  
Turn the radio back on for normal operation.

FCC Licensing 
Except for the five (5) MURS frequencies listed on page 12, the FCC requires the owners of radios operating on these frequencies to obtain a 
station license before using them.   
The station licensee is responsible for ensuring that transmitter power, frequency and deviation are within the limits specified by the station license. 
The station licensee is also responsible for proper operation and maintenance of the radio equipment. This includes checking the transmitter 
frequency and deviation periodically, using appropriate methods. 
To get an FCC license for VHF or UHF frequencies, submit FCC application Form 601. Your Ritron dealer can help you with this process.   
How to Obtain an FCC Radio License 
Because your Ritron radio operates on Private Land Mobile frequencies, it is subject to the Rules and Regulations of the FCC, which requires all 
operators of these frequencies to obtain a station license before operating their equipment. Make application for your FCC license on FCC Forms 
601, Schedules D and H, and Fee Remittance Form 159. 
To have forms and instructions faxed to you by the FCC, call the FCC Fax-On-Demand system at 202-418-0177 from your fax machine; request 
Document numbers 3000159, 3060001, 3060003, and 3060006.   
To have Document numbers 3000159, 3060001, 3060003, and 3060006 mailed to you, call the FCC Forms Hotline at 800-418-FORM (800-418-
3676).

Safety Standards 
The FCC (with its action in General Docket 79-144, March 13, 1985) has adopted a safety standard for human exposure to radio frequency 
electromagnetic energy emitted by FCC regulated equipment.  Ritron observes these guidelines and recommends that you do also: 
•  DO NOT hold the radio so that the antenna is very close to or touching exposed parts of the body, especially the face or eyes, while 
transmitting.  Keep the radio vertical, eight inches away while talking into the front panel.   
•  DO NOT press the Push-To-Talk except when you intend to transmit. 
•  DO NOT operate radio equipment near electrical blasting caps or in an explosive atmosphere. 
•  DO NOT allow children to play with any radio equipment that contains a transmitting device. 
•  Repair of Ritron products should be performed only by Ritron authorized personnel. 
Service 
Federal law prohibits you from making any internal adjustments to the transmitter, and / or from changing transmit frequencies unless you are 
specifically designated by the licensee.  
If your radio equipment fails to operate properly, or you wish to have the radio programmed, contact your local authorized dealer or Ritron.
