ALLBOX
 .......................................................  
The DMR-Series Callbox is a 2-way radio transceiver used to communicate directly with portable, mobile and stationary DMR 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. 
  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 DMR-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 DMR-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 DMR-Series callboxes will be transmitting at high power 
output (2W).  When battery powered by 3 D cells the DMR-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 DMR-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. 
  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 with a unique DMR ID code.   
  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. 
  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 DMR ID code. 
  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.

NERGY
 .............................................  
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 DMR-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 DMR-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 DMR-Series Callboxes the LOW battery alert tone can be 
replaced by a LOW battery voice message.

 ...................................  
The DMR-Series Callbox may be powered by:  
 3 internal D-cell batteries for 700mW operation. When the callbox is used in a battery only application, the Auto Turn-Off feature 
should be Enabled – this is the Factory Default setting. 
 An external 8 to 12 VDC (Use Ritron pn RPS-EXPO) source for 2W operation.  
  Powering the callbox from internal alkaline batteries will allow for an installation that does not require wiring to an external 
source of power. When the callbox is used in a battery only application, the Auto Turn-Off feature should be Enabled – this 
is the Factory Default setting. 
  Powering the callbox by an external source will allow the unit to remain in Always-ON mode, like an intercom*. Be advised 
that battery only operation is not suitable for Always-On mode.  
To extend battery life, one of two battery saver options may also be used. See “POWER MANAGEMENT OPTIONS” on page 5.  
*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 DMR-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 DMR call box can draw about 0.7 Amp when transmitting so battery health is important. 
DMR-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  DMR-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  DMR-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…………… (In battery only application Auto Turn-Off must be Enabled) …  (Field or PC Programmable) 
If Enabled (factory default), 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. Battery only operation not suitable for Always-On mode. 
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). 
DMR Radio Power Consumption  ……………………………………………………………………………… (Automatic) 
“ON with sync”: When the DMR radio is actively looking for a sync word in receive mode it consumes about 80 mA. The digital 
receiver IC is looking for the DMR 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. Battery only operation not suitable for Always-On mode. 
“Always ON”: DMR 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 DMR-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.

To match other radios, the owner can select Frequency Codes from Table 1, on page 12. In our example, we will program an RQX-
417DMR to operate on the "Brown Dot" frequency of 464.500 MHz.   
NOTES:   
 1.  Refer to Table 1 on page 12 to determine the two-digit frequency code and write it down. 
   3.  Loosen the (4) screws in the front corners of the case.  
4.  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. 
   5.  Press and release the ON/PTT button on the front of the unit to turn the radio on. 
6.  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. 
   7.  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.  
 8. Click the Program button until the program display shows the Program Code “F”.  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 2 or 3-digit Frequency code from Table 1. 
   9.  Enter the 1st digit of the frequency 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. 
   10.  Enter the 2nd digit of the frequency 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. 
 11.  If necessary, enter the 3rd digit of the frequency 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. 
   17.  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.  This will also occur if the radio frequency has 
been PC programmed to something other than one of the table codes from Table1. 
   18.  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.

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 DMR-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 DMR-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 DMR 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 DMR Decode Code required to activate the feature can be Field Programmed for the 8 
digit DMR ID. 
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. 
 KEY:   Feature is Field Programmable.

ROGRAMMING
 ............................................  
The DMR-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: 
DMR Paging Decode ..................................................................................................................... (Field or PC Programmable) 
This allows selective calling to a DMR-Series Callbox in a radio system where there is more than one Callbox. When the 
Callbox is programmed for DMR decode in Intercom (Always-On) mode it will sound an alert tone on the Callbox speaker, 
similar to a telephone ring tone, whenever the DMR 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 DMR Page is successfully decoded.  Ring Tone 
is enabled from the factory. 
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.

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 DMR 
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.  
GateGuard® – Momentary for 1   sec. ..................................................................................... (Field or PC Programmable) 
With this option selected the switch will momentarily CLOSE when a unique DMR code is received.  The switch will remain 
CLOSED for the programmed period of time, programmable for 1-255 seconds.  
GateGuard® – Toggle .................................................................................................................... (Field or PC Programmable) 
With this option selected the switch will alternately OPEN and CLOSE when it receives a unique DMR 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.  
GateGuard® – On Code / Off Code .......................................................................................... (Field or PC Programmable) 
When this option is selected the switch will CLOSE when a unique DMR code is received, and OPEN when a DMR Turn-Off code is

 ............................................................................................................................ 
The DMR-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 DMR-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 DMR-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 DMR-Series Callbox can be Field Programmed, or PC programmed using special software, for customized GateGuard® 
applications. 
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 DMR-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. 
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.  
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 DMR 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 DMR code.  After the 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 DMR Decode (receive) codes.  The DMR-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.

DMR callboxes which are fitted with an DMR board can be programmed to send DMR codes such as Color Codes and ID codes. 
Each callbox must have its unique unit ID and operate its squelch based on either receiving the proper Color Code or individual or 
group ID code. It can also be required to have both the correct Color Code and individual or group ID code. The “all call” code 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

IMPORTANT: This warranty sets forth the full extent of RITRON’s express responsibilities regarding the covered products, and is given in lieu of all 
other express warranties.  What RITRON has agreed to do above is your sole and exclusive remedy.  No person is authorized to make any other 
warranty to you on behalf of RITRON.  Warranties implied by state law, such as implied warranties of merchantability and fitness for a particular 
purpose, are limited to the duration of this limited warranty as it applies to the covered product.  Incidental and consequential damages are not re-
coverable under this warranty (this includes loss of use or time, inconvenience, business interruption, commercial loss, lost profits or savings).  
Some states do not allow the exclusion or limitation of incidental or consequential damages, or limitation on how long an implied warranty lasts, so 
the above limitations or exclusions may not apply to you.  Because each covered product system is unique, RITRON disclaims liability for range, 
coverage, or operation of the system as a whole under this warranty. 
WHO IS COVERED BY THIS WARRANTY:  This warranty is given only to the purchaser or lessee of covered products when acquired for use, 
not resale.  This warranty is not assignable or transferable.

dence of the date of purchase) and deliver it along with the product.  If RITRON chooses to repair or replace a defective product, RITRON may re-
place the product or any part or component with reconditioned product, parts or components.  Replacements are covered for the balance of the 
original applicable warranty period.  All replaced covered products, parts or components become RITRON’s property. 
RIGHTS TO SOFTWARE RETAINED :  Title and all rights or licenses to patents, copyrights, trademarks and trade secrets in any RITRON
