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.
AFB-1545 (included with radio) -2 dBi gain
RAM-1545 (optional magnet-mount antenna) 2 dBi gain
RBS-477DMR:
Using the AFB-1545 antenna (included with the product) in a vertical orientation 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. When using
the RAM-1545 (optional magnet-mount antenna with 25’ cable) in a vertical orientation a 29.4 cm separation distance is required.
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.
En utilisant l'antenne AFB-1545 (fournie avec le produit) dans une orientation verticale à la distance de séparation minimale prévue
de 20 cm (7.9 pouces) et plus, l'exposition RF maximale est bien inférieure aux limites de la population générale / non contrôlées.
Lors de l'utilisation de la RAM-1545 (antenne optionnelle à montage magnétique avec câble de 25 pi) dans une orientation verticale,
une distance de séparation de 29.4 cm est requise. Les antennes autres que celles disponibles chez RITRON n'ont pas été testées
pour leur conformité et peuvent ou non respecter les limites d'exposition aux distances indiquées. Les antennes à gain plus élevé
sont capables de générer des champs plus élevés dans la partie la plus forte de leur champ et nécessiteraient donc une plus
grande séparation de l'antenne. Ce produit ne doit pas être utilisé par le grand public dans un environnement non contrôlé, à moins
que le respect des limites d'exposition aux RF pour la population non contrôlée / générale ne puisse être assuré.
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.
• DO NOT transmitter more than 50% of the time.
• 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 and IC 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.
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition.

CHANNEL SCAN OPERATION
Channel scanning allows you to listen for broadcasts on all of your radio channels. The RBS-477DMR base radio can scan all
channels programmed into the radio. Be aware that the more channels the radio must scan the longer it takes to check each
channel.
How Scanning Works
Using the P2 BUTTON, select “Scan”. The base radio sounds a double beep, the Scan Beep, and the radio then repeatedly checks
each channel in the scan list. “Scanning” appears on the display.
When receiving a call on a channel being scanned, the base radio will stop scanning to let you hear communications on that
channel. After the transmission has ended the base radio will pause before it resumes scanning to allow you time to respond.
When transmitting from the Scan channel, the base radio will go to the last channel on which a signal was received, then transmit.
After you release the PTT the base radio 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 very busy you want to temporarily block it out. While the base radio is stopped on the
channel to be blocked, press the P2 BUTTON until “Scan Block” appears on the display 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 “Scan” or “Scan Off” is selected with the P2 BUTTON, or the CHANNEL
SELECTOR button is pressed.
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.
Last Channel Received
The base radio can be quickly set to the last channel that received a call while scanning. Press and hold the P2 BUTTON when
“Last Channel” appears on the display. Release the button after the double beep is heard on the speaker.
The radio will stop scanning and go to the channel on which the most recent call was received.
Priority Scanning (Optional)
The base radio can be optionally programmed for priority scanning. Priority Scan allows you to periodically monitor a Priority
Channel, even if the base radio has stopped on another channel. This will prevent missed calls on the primary operating channel
when in scan mode.
With Priority Scan enabled:
• 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 radio can be programmed to transmit only on the Priority Channel when scanning.
• The base radio can be programmed to sound a Priority Channel Beep whenever the base radio receives on the Priority
Channel when scanning.
See your Ritron dealer or contact Ritron directly for PC programming of this option.

RECEIVE –ANALOG CHANNELS
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 when on an Analog channel
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 base radio to screen unwanted calls.
Paging Decode 2-Tone, DTMF or Selcall 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 paging decode sequence programmed into the
radio is decoded, the radio will emit a series of ring tones similar to a telephone.
When receiving a signal with Carrier or Tone Squelch - The display will indicate the Channel Name and “Busy”
will appear on the 2nd line. The incoming signal will be heard on the radio speaker.
When receiving a signal with a Paging Code - When the base radio decodes an incoming Paging signal it will
emit a “ring” tone similar to a telephone, the display will indicate the Channel Name, and “Call” will appear on
the 2nd line. The incoming signal will be heard on the radio speaker.
When a received signal is present that does not carry the correct QC/DQC and/or Paging Code - The display
will indicate the Channel Name and “Busy” will appear on the 2nd line. The incoming signal will not be heard on
the radio speaker.
To override QC/DQC and/or Paging Decode and hear all received signals – If the P2 button has been
programmed for Monitor, the base radio can be set to receive all signals, regardless of QC/DQC and/or Paging
Code.
•Press and hold the P2 BUTTON when “Monitor” appears on the display. Release the button after the
double beep is heard on the speaker.
•The display will indicate the Channel Name and “Mon” will appear on the 2nd line. All activity on the
channel’s radio frequency will be heard on the radio speaker.
If you are unable to activate the Monitor function, the channel has been programmed for Monitor Lockout.
•To disable the Monitor function, press and hold the P2 BUTTON when “Monitor Off” appears on the display.
Release the button after the double beep is heard on the speaker.
TRANSMIT –ANALOG CHANNELS
•Normally, you should monitor the channel before transmitting and talk only when the channel is clear. If
“Busy” appears on the 2nd line of the radio display the radio channel is in use and you should not transmit
until 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.
•The display will indicate the Channel Name and “TX” will appear on the 2nd line.
•Keep talk times as short and infrequent as possible to allow others to use the channel.
•Transmitter Time Out - If you hold down the PTT button longer than 60 seconds a low tone followed by a
higher-pitched tone will sound on the radio speaker and the transmitter automatically shuts off. Release the
PTT button to resume normal operation.
QC AND DQC TONE CODES –ANALOG CHANNELS
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.

PAGING DECODE OPERATION –ANALOG CHANNELS
To use Paging Decode an analog base radio channel must be programmed for 2-Tone, DTMF or Selcall Paging Decode. The radio
does not operate with Paging Decode as it is received from the factory.
To activate Paging Decode you must first select an analog radio channel that has been programmed for Paging Decode. The
factory default setting will automatically activate Paging Decode any time the Paging Decode channel is selected.
•When the base radio decodes an incoming Paging signal it will emit a “Ring” tone similar to a telephone.
•The display will show “Call” to indicate that a call has been received.
•You can now proceed with normal two-way communication until the Paging Decode feature has been reset.
•If the Call is not answered the radio will emit a short reminder “Ring” tone once every minute.
•The “Ring” tone will sound every time a Paging signal is decoded.
•To reset Paging Decode – After a Paging Code has been successfully decoded it will not be required for
subsequent received signals until it has been reset.
•Paging Reset can be done by programming a timed automatic reset, or by resetting with the P2 Button.
•Press and Hold the P2 Button when “Paging Reset” appears on the display. Release the button after the
double beep is heard on the speaker.
An Analog Paging Decode channel can be programmed to:
•Decode 2-Tone, DTMF or Selcall.
•Emit a “Ring” tone on the speaker whenever a Paging signal is decoded.
•Require correct QC/DQC subtone for Paging Decode.
•Automatically set Paging Decode mode whenever the channel is selected.
•Automatically reset if a Paging Decode is not answered within 15 seconds.
•Send a transpond tone back to the transmitting station to confirm that the Paging signal has been received.
•Decode an All Call page.
•Decode a Group Call page (If set for 2-Tone paging, Group Call is when the first tone is sent for an extended period of
time).
•Disable the reminder “Ring” tone.
P1 OPERATION –ANALOG CHANNELS
The P1 button is used to select Analog Contacts that can be transmitted to selectively signal other radios or radio operated devices.
The RBS-477DMR radio can be programmed with 10 2-Tone, DTMF or Selcall Analog Contacts. Any number of the 10 Analog
contacts can be assigned to the P1 button on a per-channel basis.
•Press and release the P1 BUTTON until the desired Analog Contact appears on the display.
•With the Analog Contact name showing on the display, press the PTT button and the radio transmits the
selected Analog Contact code.
•If you continue to hold the PTT button down, the transmitter will remain active and voice communications
can be made after the Analog Contact code has been sent.
•The Analog Contact code will be heard on the radio speaker as it is being sent.
•Sending the Analog Contact code is a one-time occurrence, to resend an Analog Contact code it must again
be selected with the P1 BUTTON.
•This feature is only available on Analog channels.

DMR CHANNEL OVERVIEW
All communication between any two DMR digital radios will include the following four codes:
Color Code A Color Code from 0 to 15. Color Codes work much like QC/DQC codes in Analog mode, and are often used in
conjunction with an Individual ID or Group ID code to screen calls when receiving, and to uniquely identify the
radio when transmitting.
SUID The Subscriber Unit ID Code (from 1 to 16,776,415) is the unique Individual ID of the radio. When an incoming
message type is Individual and matches the radio SUID, the message will be received.
Group ID A Group ID code (from 1 to 16,776,415) determines which call-groups the receiver belongs to. The radio can be
programmed to receive up to 48 different Group ID codes on any DMR channel. Group ID codes are stored in
the radio as DMR Contacts where an 8-character name can be assigned. The DMR Contact name will appear
on the display when the Group ID is received.
Call Type Call types are Group, Individual or All Call.
•With a Group call type the radio will transmit and receive Group ID codes that match those programmed into
the selected radio channel.
•With an Individual call type the radio will transmit a call that match the SUID of the individual radio you
intend to contact.
•With All Call type the radio receives any Group call, regardless of radio programming.
RECEIVE –DMRCHANNELS
The radio can only receive broadcasts while the Push-To-Talk button is not being pressed. To hear incoming calls the Color Code
AND Group Call code, Individual ID code, or the All Call code must match the RX Contacts programmed into the radio channel.
When the radio is in standby mode with no incoming signal
•The display will indicate the Channel Name.
When receiving a valid DMR call with an ID code contained in the DMR RX Contacts list
•The DMR Channel Name will appear on the 1st line of the display.
•The Incoming DMR Contact Name will appear on the 2nd line of the display.
•The incoming signal will be heard on the radio speaker.
•When the incoming signal has ended the display will continue to show the DMR Contact for the
programmed DMR Hold Time to allow a response to the call.
When receiving a valid Individual DMR call with an ID code not contained in the DMR RX Contacts list
•The DMR Channel Name will appear on the 1st line of the display.
•The Incoming DMR Individual SUID code will appear on the 2nd line of the display.In this example the
caller’s SUID is 12345678.
•The incoming signal will be heard on the radio speaker.
•When the incoming signal has ended the display will continue to show the DMR Individual SUID code for
the programmed DMR Hold Time to allow an Individual response to the call.
When a received signal is present that does not match channel programming
•The display will indicate the Channel Name and “Busy” will appear on the 2nd line.
•The incoming signal will not be heard on the radio speaker.
