2013 FCC NARROWBAND MANDATE 
On January 1, 2013, pursuant to the FCC Narrowband mandate, 
Ritron will no longer be allowed to manufacture wide band (25 
kHz) capable radio equipment that operates in the frequency 
bands from 150 MHz to 512 MHz.  All Ritron “Display Series” 
Base Radios are FCC certified for narrowband operation, so the 
only change required is the elimination of wideband operation.   
To meet the FCC narrowband mandate by Jan 1, 2013, Ritron 
will initiate the transition process of manufacturing narrowband 
only compliant radio equipment beginning July 1, 2012.  After 
that date, customer orders will begin to be filled with radios 
manufactured for FCC narrowband compliance, with no 
provisions for wideband operation except where allowed by FCC 
rule.  These radios will be clearly marked as “FCC Narrowband 
Compliant”.  The narrowband manufacturing process will 
proceed gradually on a model by model basis, with all models 
narrowband compliant by the January 1, 2013 deadline.  
For a complete list of Ritron radios capable of narrowband 
operation; a Ritron FAQ on the subject, and various links on the 
FCC website dealing with Narrowbanding go to: 
www.ritron.com/narrowband

numbers as they are scanned. If a signal is received the channel 
display will indicate the channel number, and when the received 
signal is removed the radio will wait briefly, sound the Scan 
Beep, then scanning will resume as normal.  
If the Weather Channel is selected - on a VHF radio the display 
will light a single segment of the display that indicates which of 
the seven NOAA frequencies is monitored. See the “NOAA 
Weather Radio Feature” section on page 10 for details.  
RECEIVE  
To hear calls from other users - adjust the volume as desired. 
The radio can only receive broadcasts while the Push-To-Talk 
button is not being pressed. Whether or not you hear these 
broadcasts depends upon the squelch settings.  
There are three standard squelch modes that can be used in the 
JBS / PBS “D-Series” base station.  
 Carrier Squelch lets you hear all broadcasts on your channel 
strong enough for the radio to detect, and silences noise.  
 Tone Squelch uses the QC or DQC “tone squelch” format 
available on the JBS / PBS. This allows you to screen out 
“on-channel” broadcasts that do not carry the correct code 
programmed for the radio.  
 2-Tone Paging can be used in conjunction with either 
carrier or tone squelch to block out all calls except those 
sent specifically to your radio. When the unique 2-tone 
sequence programmed into the radio is decoded, the radio 
will emit a series of ring tones similar to a telephone.  

OPERATION 
  Have questions?  Call 800-USA-1-USA (800-872-1872) or visit our website at www.ritron.com page 5 
When Carrier or Tone Squelch is selected by the user, all 
channels will operate in that mode. The JBS / PBS “D-Series” 
base station will operate in tone squelch mode when it is first 
turned on.  
QC AND DQC TONE CODES  
Tone codes filter out static, noise and reduce unwanted “chatter” 
on radio channels. When you operate on a frequency with a tone 
code, you screen out most interference. This allows you to 
communicate with less interference and to hear only those users 
in your radio group.  
IMPORTANT!  All radios in the talk group must operate on the 
same frequency and tone code.  
SQUELCH MODES 
To activate Tone Squelch or Carrier Squelch and to Monitor the 
channel - you may either simultaneously press both the On / 
Volume Up and Volume Down / Off volume buttons and hold 
briefly before releasing, or if the “Z” button is set for the monitor 
function (see page 15), then press the “Z” button and release. To 
advance to the next squelch mode simultaneously press both 
volume buttons, or press the “Z” button.  
1.  If the base station emits a SINGLE beep, then Tone Squelch 
is turned ON and you will only hear radio transmissions on 
that channel with the same QC or DQC tone codes as your 
base station.  
2.  If the base station emits a DOUBLE beep, then you are in 
Carrier Squelch and you can Monitor all broadcasts on the 
channel. To exit Carrier Squelch press and hold both 
volume buttons until you hear the SINGLE beep.  
3.  If the base station emits a TRIPLE beep, then you are in 2-
TONE DECODE. You will only hear broadcasts that first send 
your two unique paging tones. If you are unable to set the 
base station, you have selected a channel that is not 
programmed for 2-Tone Decode.  
If you are unable to activate Carrier Squelch - the base station 
has been programmed for Monitor Lockout. See your Ritron 
dealer or contact Ritron directly to disable this option.  
Using the “Z” button for Monitor - the JBS / PBS “D-Series” base 
station “Z” button can be programmed for Monitor mode.  
To use the “Z” button for Monitor see ‘How to Field Program 
Radio Feature Codes” on page 15.  
Note:  It is possible that the beginning of a call might be missed 
while the base station is in battery saver mode. If this 
happens, ask the caller to repeat the message.  
TRANSMIT  
Normally, you should monitor the channel before transmitting 
and talk only when the channel is clear.  
To transmit - hold down the Push-To-Talk button and, with the 
radio at least 6 inches away, talk into the microphone. Speak in a 
normal tone, since talking louder will not improve the listener’s 
reception.  
Keep talk times as short and infrequent as possible to allow 
others to use the channel.  
   A Transmit / Busy Lamp in the lower right corner of 
the Channel Display lights whenever the transmitter 
is activated and blinks when the channel is busy.  
FIG-3: TRANSMIT / BUSY LAMP 

OPERATION 
  Have questions?  Call 800-USA-1-USA (800-872-1872) or visit our website at www.ritron.com page 6 
RADIO ALERT TONES  
The base station responds to certain instructions by sounding a 
beep or series of tones. These tones can tell you that the radio is 
working as you expect.  
Power On / Self Check “OK”  
When it is first turned on, the base station runs a quick “self test” 
to confirm basic functions. When complete the base station will 
emit the Channel Beep and the Channel Display will show the 
operating channel. The base station is then ready to use.  
Error Tones  
However, if the “self test” detects a diagnostic error, an error 
tone sounds. The error tone indicates the base station frequency 
synthesizer is malfunctioning. Turn off the radio and try again. 
The error tone will also sound if a channel has been 
programmed for an invalid frequency.  
A long, low-pitched tone means the battery voltage is too low to 
operate the base station. If you cannot correct the problem, 
consult an authorized Ritron service center or Ritron directly.  
Squelch Mode  
When you press and hold both Volume buttons at the same time, 
a SINGLE beep will sound to indicate that tone squelch is on. A 
DOUBLE beep means that carrier squelch is on. If the channel is 
programmed for 2-Tone Code, a TRIPLE beep indicates that the 
base station is in 2-Tone Decode mode.  
Transmitter Time Out  
A low tone followed by a higher-pitched tone sounds and the 
transmitter automatically shuts off if you hold down the PTT 
button longer than 60 seconds.  
Battery Alert Tone  
In battery powered installations: Once the battery voltage drops 
below the required “operating voltage” the radio emits a long, low 
tone and turns itself off.  
OPTIONAL ALERT TONES  
The “Display Series” base station can be programmed using the 
RITRON PC Programmer for optional alert tones. See your 
Ritron dealer or contact Ritron directly for programming of these 
options.  
Courtesy Beep  
A short tone sounds at the end of each received transmission to 
indicate that the channel is clear and you may transmit.  
Busy Channel TX Inhibit  
If a user is transmitting on your radio frequency without your 
tone, you will not be allowed to transmit. The base station will 
beep a series of long, low tones while the PTT is held down (like 
a busy signal).  
Transmit Clear to Talk Beep  
A short tone sounds after the PTT has been pressed to indicate 
that the base station is ready for you to begin talking.  

OPERATION 
  Have questions?  Call 800-USA-1-USA (800-872-1872) or visit our website at www.ritron.com page 7 
CHANNEL SCAN OPERATION  
Channel scanning allows you to listen to broadcasts on your 
radio channels. The JBS / PBS “Display-Series’ base station will 
scan all channels programmed into the radio except the NOAA 
Weather Channel.  
How Scanning Works  
Using the Channel Selector button, select the Scan channel. The 
base station sounds the Scan Beep, and then repeatedly checks 
each channel in the scan list. The channel display will show the 
channel numbers as they are scanned.  
When receiving a call on a channel being scanned, the base 
station will stop scanning to let you hear communications on that 
channel. After the transmission has ended the base station will 
pause before it resumes scanning to allow you time to respond.  
When transmitting from the Scan channel, the base station will 
go to the last channel on which a signal was received, then 
transmit.  After you release the PTT the base station will pause 
to allow time for a response, and then resume scanning.  
Temporary Busy Channel Blocking  
If one of the channels in the scan list is so busy that you want to 
temporarily block it out, press the Channel Selector button while 
the base station is stopped on the channel to be blocked and 
hold it until scanning resumes. The blocked channel will now be 
skipped in the scan list.  
The blocked channel will be returned to the scan list if the base 
station is turned off and then back on again, or when the radio 
channel is changed using the Channel Selector button. The first 
channel in the scan list cannot be blocked.  
To turn Channel Scan On / Off see “How to Field Program 
Radio Feature Codes” on page 15.  
Last Channel Scanned Alert Tone  
When changing channels with the Channel Selector button, an 
alert tone will sound to indicate the last channel that received a 
message when the radio was scanning. This will identify the 
channel on which the last message was received, and allow 
uninterrupted transmission on that channel without the 
constraints of scanning. You can then press the Channel 
Selector button to return to the scan channel.  
Using the “Z” Button for Scan  
The special feature “Z” button can be programmed to initiate 
scanning. The UHF JBS-446D and PBS-446D base stations are 
programmed for “Z” button Scan channel operation from the 
factory.  
To select the Scan Channel, press the “Z” button. The radio 
sounds the Scan Beep, and scanning operation is initiated. The 
Scan channel will not be accessible with the Channel Selector 
button when the base station is programmed for ‘Z” button Scan 
channel operation.  
To return to normal channel operation, press the Channel 
Selector button and the base station will return to channel 1.  
To temporarily block a busy channel while scanning, press the 
“Z” button while the base station is stopped on the channel to be 
blocked and hold it until scanning resumes. The blocked channel 
will now be skipped in the scan list.  
Priority Scanning (Optional)  
The “Display Series” base station can be optionally programmed 
for priority scanning. Priority Scan allows you to periodically 
monitor a Priority Channel, even if the base station has stopped 
on another channel. This will prevent missed calls on the primary 
operating channel when in scan mode.

With Priority Scan enabled:  
  The first channel in the scan list is the Priority Channel.  
  The radio checks the Priority Channel every two seconds to 
check for activity. This time is programmable and can be set 
for 1 - 8 seconds.  
  The base station can be programmed to transmit only on the 
Priority Channel when scanning.  
  The base station can be programmed to sound a Priority 
Channel Beep whenever the base station receives on the 
Priority Channel when scanning.  
See your Ritron dealer or contact Ritron directly for PC 
programming of this option.  
2-TONE DECODE OPERATION  
To use 2-Tone Decode the “Display Series” base station 
must be PC programmed for this option, the radio does not 
operate with 2-Tone decoding as it is received from the factory. 
See your Ritron dealer or contact Ritron directly for PC 
programming of this option. This feature allows the base station 
to act as a monitor receiver.  
To activate 2-Tone Decode you must first select a radio channel 
that has been PC programmed for 2-Tone Decode. The factory 
default setting will automatically activate 2-Tone Decode any 
time the 2-Tone Decode channel is selected. If not, 
simultaneously press both of the volume buttons and hold briefly 
before releasing. The radio sounds three beeps when 2-Tone 
Decode is turned on.  
If you are unable to set the base station, you have selected a 
channel that is not programmed for 2-Tone Decode.  
When the base station decodes an incoming 2-Tone signal it will 
emit a “ring’ tone similar to a telephone and the display will show 
a “C” to indicate that a call has been received. You can now 
proceed with normal two-way communication until the 2-Tone 
Decode feature has been reset. The “ring” tone will sound every 
time a 2-Tone signal is decoded.  
   The display will show a “C” to indicate that a 2-Tone call 
has been received.  
FIG-4: 2-TONE CALL ALERT 
To reset 2-Tone Decode after receiving a call: Simultaneously 
press both of the volume buttons and hold briefly before 
releasing. The base station sounds three beeps when 2-Tone 
Decode is reset and the display will show the channel number. 
The base station can be optionally programmed to automatically 
reset if a call is not answered within 15 seconds.  
2-Tone Decode channels can be programmed to:  
  Automatically set the base station for 2-Tone Decode mode 
whenever the channel is selected.  
  Automatically reset if a 2-Tone Decode is not answered 
within 15 seconds.  
 Automatically place the receiver into carrier squelch “monitor” 
mode whenever a 2-Tone Decode has been decoded.  
  Send a transpond tone back to the transmitting station to 
confirm that the 2-Tone signal has been received.  
  Decode an All Call tone.  
  Decode a Group Call if the first tone is sent for an extended 
period of time.

HOW TO SELECT YOUR LOCAL NOAA WEATHER FREQUENCY (VHF MODELS ONLY)  
The base station is shipped from the factory without a NOAA frequency selected. You must first 
select your local NOAA frequency to activate NOAA weather features.  Follow steps 1-7 below.  
VHF models of the JBS / PBS “Display Series” base station can hear weather forecasts from the 
National Weather Service which are broadcast on one of the seven NOAA weather frequencies. In 
some areas you may be able to receive more than one broadcast.  
1.   Follow the steps in FIG-5 on page 11 to place the radio into the Weather Frequency Select mode.  
2.   The base station will scan to the first NOAA frequency where a broadcast is present. The 
display will light a single segment to indicate the NOAA frequency per FIG-6 on page 11.  
3.  Monitor the channel for a few minutes to be sure it is the broadcast for your local area.  
4.   Press the “Z” button to scan for the presence of any other NOAA broadcasts, monitoring each 
broadcast and noting the frequency as indicated by the display.  
5.   Using the “Z” button, select the local NOAA frequency you would like your radio to operate on.  
6.   Turn the base station off by pressing the Volume Down / Off button.  
7.   When the base station is turned back on all weather features will operate on the selected 
NOAA frequency.  
NOTE:  If the base station is moved, for example, to another state you must re-train your base 
station with a new local NOAA frequency. 
NOAA Weather Radio (NWR) is a nationwide network of radio stations broadcasting continuous weather information direct 
from a nearby National Weather Service office. NWR broadcasts National Weather Service warnings, watches, forecasts 
and other hazard information 24 hours a day.  
Working with the Federal Communication Commission’s (FCC) Emergency Alert System, NWR is an “all hazards” radio 
network, making it your single source for comprehensive weather and emergency information. NWR also broadcasts 
warning and post-event information for all types of hazards—both natural (such as earthquakes and volcano activity) and 
environmental (such as chemical releases or oil spills).  
Known as the “Voice of the National Weather Service,” NWR is provided as a public service by the National Oceanic & Atmospheric Administration 
(NOAA), part of the Department of Commerce. NWR includes more than 750 transmitters, covering all 50 states, adjacent coastal waters, Puerto 
Rico, the U.S. Virgin Islands, and the U.S. Pacific Territories. NWR requires a special radio receiver or scanner capable of picking up the signal. 
Broadcasts are found in the public service band at these seven frequencies (MHz): 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550.  
NOAA WEATHER FEATURE  
After you have selected a NOAA weather 
frequency on your VHF model base 
station, an extra channel is automatically 
created exclusively for listening to 
National Weather Service broadcasts.  
Repeatedly pressing the Channel button 
will advance through your base station 
talk channels. NOAA Weather will be 
your last channel, and the display will 
light the segment representing the 
selected NOAA frequency.  
If you do not want the NOAA Weather 
feature, it can be turned off through Field 
Programming.  
To turn NOAA Weather Feature On / 
Off see “How to Program Radio 
Feature Codes” on page 15.

NOAA WEATHER ALERT FEATURE  
Once a NOAA weather frequency has been selected on your VHF model base station it will 
listen for emergency broadcasts from the National Weather Service, regardless of which 
channel you are on.  
An alert tone will sound in the speaker, the display will show an “A” (as shown), 
and the National Weather Service emergency broadcast will be heard - advising 
you of threatening weather conditions.  
NOTE:   NOAA sends a test alert tone once each week. Your base station will 
respond to this alert.  
To turn Weather NOAA Alert On / Off see “How To Field Program Radio Feature 
Codes” on page 15.  
  Pressing the Channel button will return you to your normal talk channel.  
  If you do not want the NOAA Weather Alert feature, it can be turned off through Field 
Programming, refer to page 15.  
USING THE “Z” BUTTON TO ACCESS NOAA WEATHER

HOW TO DELETE A CHANNEL  
Following the instructions in “How to Field Program Frequency & 
Tone Codes” on page 13, enter a Frequency Code of “00” and a 
Tone Code of “00”. Once a channel has been deleted it is no longer 
available with the Channel Selector.  
A deleted channel can be added back at any time. To add a deleted 
channel back, follow the instructions in “How to Field Program 
Frequency & Tone Codes” on page 13.  
PC PROGRAMMABLE FEATURES  
The “Display Series” base station has many features that are only 
available through PC programming. See your Ritron dealer or 
contact Ritron directly for PC programming of these options.  
Receive and Transmit Frequency on any channel can be 
programmed to any valid frequency within its designated band. (See 
“Display Series Model Numbers” for frequency bands)  
Squelch Tightener on any channel can adjust carrier squelch UP to 
block distant signals or DOWN to hear more distant signals.  
Wide or Narrow Band transmit operation can be set per channel. 
Refer to the section FCC Narrowband Mandate to see if your radio is 
capable of wideband transmit operation. 
Monitor Lock Out can be set on any channel to prevent monitoring 
of the channel, only broadcasts with the correct QC or DQC code 
can be heard.  
Transmit Inhibit on Busy Channel can be set on any channel to 
prevent transmitting when a broadcast is present on the receiver that 
does not carry the correct code. This feature is usually used in 
conjunction with Monitor Lock Out.  
Transmit Time Out time can be changed.  
Power Saver “sleep” time can be set, or power saver can be 
disabled.  
Courtesy Beep sounds a short tone at the end of each received 
transmission to indicate that the channel is clear and you may 
transmit.  
Transmit Clear To Talk Beep  Any channel can be set to sound a 
short tone after the PTT has been pressed to indicate that the base 
station is ready for you to begin talking.  
Disable Field Programming to allow only PC programming.  
Channel Scan can be programmed or edited to include any of the 
radio channels, even channels that are not selected with the 
Channel Selector button. Other programmable scan features include 
scan resume delay time, busy channel blocking, last active channel 
beeps, and priority scanning options.  
2-Tone Paging Decode can be set on any channel. Programmable 
options include the setting of the 2-Tone frequencies and duration, 
All Call, Group Call, Call Transpond, automatic setting of 2-Tone 
Decode when the channel is selected, automatic reset of the 2-Tone 
Decode if a call is not answered within 15 seconds, and 
automatically set the base station to carrier squelch mode after a 2-
Tone signal is received.  
* 2-Tone Encode  Each channel can be programmed with a unique 
pair of 2-Tone encode frequencies between 300-1500 Hz. Pressing 
the “Z” button will send the 2-Tone Code.  
* DTMF ANI  A unique DTMF ANI string can be programmed 
separately for each channel.  Pressing the “Z” button will send the 
DTMF ANI. 
*  Note:   A channel can not be programmed to do both DTMF ANI 
and 2-Tone Encode.

OBSERVE CAUTION IN THE FOLLOWING 
ENVIRONMENTS TO MAXIMIZE THE LIFE 
OF YOUR RADIO EQUIPMENT:  
LOCATION: Be aware that this radio and / 
or antenna may create interference with, or 
be interfered with, by nearby electronic 
equipment such as computers, monitors, 
keyboards, electronic telephones and other 
sensitive devices. Either move the 
equipment or use a remote antenna to 
separate components sufficiently to stop or 
reduce interference.  
MOISTURE: “Display Series” base radios 
are not waterproof. DO NOT directly expose 
them to rain or excessive moisture.  
CHEMICALS: Detergents, alcohol, aerosol 
sprays or petroleum products can damage 
the radio case. DO NOT use petroleum 
solvents of any kind; use a soft cloth 
moistened with water to clean the case.  
EXTREME HEAT: High temperatures can 
damage the radio and its components. DO 
NOT expose the units to extreme heat or 
leave them in direct sunlight.  
EXCESSIVE TRANSMISSIONS: DO NOT 
hold the Push-To-Talk switch down longer 
than necessary during transmission 
intervals.  
VIBRATION / SHOCK: Although your 
“Display Series” base radio is designed to be 
rugged, it will not survive excessive abuse. 
Avoid dropping the radio.  
EXPOSURE TO RADIO FREQUENCY ENERGY:  
These products generate radio frequency (RF) energy when the PTT button on the 
front of the unit is depressed. The product has been evaluated for compliance with 
the maximum permissible exposure limits for RF energy at the maximum power 
rating of the unit when using antennas available from RITRON. Antennas other than 
those mentioned below 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.  
JBS-446D: Using the AFB-1545 antenna included with the product at the 20 cm (7.9 
inches) minimum expected separation distance and greater, the maximum RF 
exposure is well below the General Population/Uncontrolled limits.  Antennas other 
than those available from RITRON 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.  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:  
  Use only the antenna(s) available from RITRON for these models. DO NOT 
operate the radio without an antenna.  
  Keep talk times as short and infrequent as possible. DO NOT depress the PTT 
button when not actually wishing to transmit. These radios are equipped with an 
internal timer to limit continuous transmit times.  
  When transmitting, make certain that the distance limits for the particular model in 
use are observed.  
 DO NOT allow children to operate the radio.

TROUBLESHOOTING 
  Have questions?  Call 800-USA-1-USA (800-872-1872) or visit our website at www.ritron.com page 18 
 NOTES 
1.   Reception can often be improved if you relocate 
by a short distance. This effect is more noticeable 
inside buildings.  
  The range of the “Display Series” base radio is 
approximately two miles, line-of-sight.  
2.   If your radio does not detect calls from other 
radios on the channel, turn off Quiet Call by 
pressing and holding both volume buttons at the 
same time—a double beep indicates Quiet Call is 
off.  
3.   Without use of a repeater: To hear a call, select a 
channel programmed to receive the caller’s 
transmit frequency. To call another unit, select a 
channel programmed to transmit the other radio’s 
receive frequency.  
   Using a repeater: A radio channel can hold two 
separate operating frequencies, one for receive 
and one for transmit. Your channel must work 
with the repeater’s transmit and receive 
frequencies.  
   NOTE: A dealer must program the radio for 
repeater operation.  
4.    An optional RM-7 Remote Speaker / Microphone 
and headset, plus the CCL-M 12 VDC Adapter, 
allow operation in a vehicle. See page ii for 
accessories.  
5.   To “talk” with each other, radios must be 
programmed identically for Quiet Call code, as 
well as frequency. Each code is unique; radios 
respond only to the code programmed.  
   Press and hold both volume buttons at the same 
time.  
    A single beep indicates Quiet Call squelch is on.  
    A double beep indicates Quiet Call squelch is off.  
CHART 
If you have trouble operating the base radio, review the Control & Operation, pages 3 through 9. If you 
think the base radio is malfunctioning, check the list below.  
Problem  Possible Solutions  
GENERAL  
The radio does not work at 
all.  
  Make sure the 120 VAC outlet is active and the RPS-1B power 
supply is connected. 
Operating features do not 
work exactly as expected.  
  The radio has been dealer programmed for customized operation. 
(Consult dealer.) 
Reception is poor.  
  Move to a different location. (See Note 1.)  
  Confirm the proper antenna is connected to the radio. 
  Use an optional high-gain antenna. See page ii, Optional 
Accessories. 
You cannot hear calls from 
other radios.  
  Turn off Quiet Call (coded) squelch. (See Note 2.)  
  Ensure radio receives the same frequency the caller transmits. 
(See Note 3.)  
Your calls cannot be heard in 
other radios.  
  Make sure that your radio transmits on the receive frequency of the 
radio(s) you want to call. (See Note 3.) 
ERROR TONES  
An error tone sounds when 
the radio is first switched on.  
 See “Error Tones” on page 6. 
An error tone occurs while 
transmitting.  
 Refer to “Transmitter Time-Out,” page 6.  
QUIET CALL  
You cannot screen out calls 
from users outside of your 
Quiet Call group.  
  Make sure that the channel is programmed with Quiet Call. 
  Activate coded squelch. (See Note 5.)  
You cannot hear Quiet Call 
messages while in Quiet Call 
(coded) squelch.  
  Confirm that the channel is programmed to detect the same code 
as the calling radio(s) transmits. (See Note 5.) 
Others in your Quiet Call 
group cannot hear your Quiet 
Call messages.  
  Verify that you transmit the same code as the radio(s) you call are 
programmed to detect. (See Note 5.)  
SCAN  
The radio constantly stops on 
a busy channel, preventing 
you from hearing calls on.  
 Skip over the interfering channel when scanning. See “Temporary 
Busy Channel Blocking” on page 7.  

SPECIAL APPLICATION 
  Have questions?  Call 800-USA-1-USA (800-872-1872) or visit our website at www.ritron.com page 19 
HOW TO FIELD PROGRAM 2-TONE ENCODE CODES  
For special applications, it is possible to use your Ritron portable radio or 
base station for remote control applications; such as opening or closing a 
gate remotely (see Ritron GateGuard at www.ritron.com/pdf/gg_07.pdf). 
This application requires you to program the radio(s) that will be sending 
the command for 2-Tone code operation, and radio(s) that will be 
receiving the command (e.g. Ritron Callbox) for 2-Tone Encode 
operation. The 2-Tone Codes must match.  
The user can field program each channel with one of the 9 pre-set 2-
Tone Codes specified in Table 5. These codes correspond to field 
programmable 2-Tone Codes available in the Ritron 6-Series or 7-Series 
OUTPOST Callbox. In our example we will program a UHF radio to 
operate with 2-Tone Code #94.  
Important Note:  
You can ADD a 2-Tone Code to a channel if the Frequency Code and Tone 
Code are not changed.  Changing the Frequency Code or Tone Code of a 
channel will ERASE any 2-Tone Code programmed on that channel. You 
must FIRST re-program the channel to the desired Frequency Code and Tone 
Code and then SAVE the entry by pressing the On / Volume Up button, then 
you may enter your 2-Tone Code, remember you must also SAVE this entry 
by pressing the On / Volume Up button.  
1.   Refer to Table 5 to determine the 2 digit, 2-Tone Code(s) you wish to 
program into each specific channel.  
2.   Follow the instructions in Fig 7, page 12 to place the radio in the 
“Program / Readout Mode”.  
3.   Using the channel button and the LED display on the radio, select the 
channel number you want to program a 2-Tone Code into.  
   4.   Enter the 1st digit of the 2-Tone code by clicking the PTT 
button until the program display shows the desired 
number. Pause—the radio will sound a low tone and 
show a hyphen across the display to indicate that it is 
ready to accept the next digit.  
   5.   Enter the 2nd digit of the 2-Tone code by clicking the PTT 
button until the program display shows the desired 
number. Pause—the radio sounds a low tone and will 
show a hyphen across the display.  
6.   After you have entered the two digits, press and release the On / 
Volume Up button to SAVE the entry. The LED display will briefly 
show the channel number you have just programmed and then a 
hyphen, the radio will sound a triple beep to indicate that 
programming was successful.  
  An ERROR tone will sound if you attempt to save an incorrect code, 
an “E” will appear on the LED display. Check the digits you are 
attempting to program and start over.  
7.   You may program each channel with the same or a different 2-Tone 
Code by repeating steps 3-6.  
8.   Turn the radio OFF and then ON again for normal operation. The “Z” 
button is used to send the 2-Tone Code. See HOW TO SEND A 2-
TONE CODE below. 
   If more than 5 digits are displayed during readout, the radio has been 
programmed for 2-Tone Encode. The frequency and tone codes will 
be displayed, followed by a “C”, then the radio will display the 2-Tone 
Code; see Table 5. In this example a UHF radio was programmed to 
operate on the “Brown Dot” Frequency Code 04 (464.500 MHz) with 
Tone Code 12 (100.0 Hz) and 2-Tone Encode Code 94.  
  Frequency Code  Tone Code  2-Tone Code   
HOW TO SEND A 2-TONE CODE  
1.   Select a channel that has been programmed with a 2-Tone Code.  
2.   Press the “Z” button to send the 2-Tone Code programmed for that 
specific channel.

LICENSING  
The FCC requires the owners of the radios 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 a FCC license for VHF or UHF frequencies, 
submit FCC application Form 600 as indicated in the 
block at right. Your Ritron dealer can help you with 
this process.  
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, four 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.

JBS-146i-A and JBS-446D-A Instructions 
Auto Turn On When Power Restored 
Ritron models JBS-146i-A and JBS-446D-A have been built to operate any time power is applied to the base radio, eliminating the need 
to press the On/Volume Up button to turn the radio on.   
The JBS-146i-A and JBS-446D-A model base radios ............................................................................................................................  
•  Will turn on any time power is applied to the radio, allowing it to automatically turn back on after a power failure. 
•  Will store the current channel in EEPROM each time the channel is changed, assuring that the radio will automatically restart 
to the current operating channel after a power outage.  As an alternative, the radio can be PC programmed to turn on to 
channel 1 whenever power is applied. 
•  Will not turn-off by pressing the Volume Down/Off button.  The only way to turn the radio off is to remove power. 
•  Will restart to a mid volume level after a power outage.  As an alternative, this option can be disabled using the PC 
Programmer and the radio will turn on at minimum volume. 
•  Will not turn-off as a result of a low battery condition, therefore, the JBS-146i-A is not recommended for battery powered 
applications. 
•  Does not have Power Save capability for battery conservation. 
•  Requires Ritron PC Programmer 9.6.0 or higher. 
To place the JBS-146i-A or JBS-446D-A into field programming mode ..............................................................................................  
1.  Remove power from the JBS-146i-A or JBS-446D-A base radio. 
2.  Hold down the PTT button and re-apply power. 
3.  Continue to hold the PTT until the beeping has stopped, then release. 
4.  The radio will display a series of six characters for Radio Identification, then a triple beep will be heard indicating that the JBS-
146i-A or JBS-446D-A base radio is in program mode. 
5.  When programming is complete, remove power and re-apply to return the radio to normal operating mode.
