SAFETY PRECAUTIONS
RADIO MOUNTING LOCATION
Consider driver and passenger safety when you hoose a lo ation for the radio.
Do not mount the unit overhead or on a sidewall unless you take spe ial pre autions,
su h as se uring the radio with a retaining strap.
Improper installation in reases the possibility that a ar a ident ould dislodge
the radio and make it a dangerous proje tile.
VEHICLE OPERATION
ELECTRONIC SYSTEMS
Che k the vehi le's manual for possible warnings about operating a two-way
radio in a vehi le equipped with an ele troni ignition or anti-skid braking system.
LIQUEFIED PETROLEUM (LP) GAS FUEL SYSTEM
Radio installation in a vehi le fueled by liquefied petroleum (LP) gas (with the LP
gas ontainer stored in a sealed-off spa e, su h as the trunk) must onform to
NFPA (National Fire Prote tion Asso iation) standard 58.
BATTERY POWER
Avoid leaving the radio turned on for long periods when the engine is off, whi h
ould run down the vehi les battery. page 3
page 21
Notes
1) Re eption an often be improved by moving a short distan e. The strength of a
radio broad ast and therefore its overage is de reased by distan e and
obstru tions (natural and man-made). This in ludes hills, valleys, foliage,
buildings, basements and other metal or on rete stru tures. The best range and
overage is obtained a ross flat terrain, with line-of-sight visibility and no
obstru tions.
2) If the radio speaker makes a ontinuous rushing noise, press and release the
monitor button to a tivate arrier squel h. Otherwise, this button toggles Quiet-
Call ( oded) squel h on and off.
If pressing and releasing this button does not toggle Quiet Call squel h on and
off, the radio has been dealer or fa tory programmed for optional monitor
operation. In this ase, pressing and holding the monitor button will turn off
Quiet Call squel h and allow you to monitor the hannel. Quiet Call squel h
automati ally resumes when you release the monitor button.
3) If you want to hear a all, you must sele t a hannel that is programmed to re eive
the aller's transmit frequen y. If you want to all another unit, you must sele t
a hannel that is programmed to transmit the other radio's re eive frequen y.
However, if you use a repeater, your hannel must be programmed to work with
the repeater's transmit and re eive frequen ies. (A hannel an hold two
separate radio frequen ies, one for re eive, the other for transmit.)
4) If you get repeating error tones when you press the PTT, the hannel might be
programmed for "Re eive Only." If so, the hannel does not ontain a transmit
frequen y, and annot be used to transmit. Repeating tones will sound if the
Busy Channel Transmit Inhibit feature is a tivated and another user's radio
signal is present on the hannel.
5) In order for radios to ommuni ate using Quiet Call, they must be programmed
with the same Quiet Call ode. Ea h ode is unique, and your radio will respond
only to the ode programmed for the hannel sele ted. Note that a hannel
may have been programmed to transmit one ode, and re eive (dete t) another
ode.
TROUBLESHOOTING

SPECIAL FEATURES
RECEIVER SQUELCH TIGHTNER FACTOR
This feature reduces distant "co-channel" or other interference for channels
that are not progra ed with Quiet Call. Carrier squelch is set for axi u
sensitivity at the factory, but can be adjusted to ute weak radio signals.
CHANNEL MONITOR LOCK OUT
This function can be progra ed to prevent a radio user fro listening to other
licensees on a shared channel. The trans it/busy la p indicates whether the
channel is busy. Quiet Call or Digital Quiet Call ust be used with this option.
BUSY CHANNEL TRANSMIT INHIBIT
Busy Channel Trans it Inhibit keeps the radio fro broadcasting if the channel
is busy, and is often used with Channel Monitor Lock Out. If you press the
icrophone PTT while the channel is busy with a signal not intended for your
radio (not carrying your Quiet Call code), the Busy Channel Trans it Inhibit
feature sounds a "busy" tone in the speaker and keeps the trans itter off.
REDUCED TRANSMIT POWER
This feature allows for reduced trans itter power on individual channels, which
ight be required by so e FCC licenses.
PAGING QUIET-CALL TRANSPOND
If you receive a page and do not answer within three seconds, this feature
auto atically activates your radio's trans itter and sends an acknowledge-
ent tone to the calling party.

SCANNING (NORMAL/PRIORITY)
___________________________________________________________________________
HOW TO:
SCAN - hang up the microphone and select the channel that contains your scan list
STOP SCANNING - take the microphone off-hook or, change channels
___________________________________________________________________________
GENERAL
Scanning auto atically lets you listen to broadcasts on different radio channels
(frequencies). The channels to be scanned are kept in a "scan list." This list is
stored in a radio channel. A channel cannot hold both a scan list and a radio
frequency.
HOW SCANNING WORKS
When you select a channel that contains a scan list (and the icrophone is
on-hook), the radio displays the channel nu ber, pauses, sounds a tone, and
then scans, displaying each channel of the scan list in turn. Channels are
scanned in the order that they were progra ed into the list. When a broadcast
is received on a channel being scanned, scanning stops to let you hear co -
unications on that channel. Scanning resu es when the trans ission ends.
The icrophone ust be in its hang-up clip for scan to work. If you lift the
icrophone fro its hang-up clip OR press the channel button, scanning stops.
(Whether scanning stops on the last active channel or on the priority channel is
dealer-progra able.) If you select a channel that contains a scan list and the
icrophone is off-hook, the radio skips to the next channel.
Using the onitor button does not interrupt scanning. Additionally, if you take
the icrophone off-hook to stop scanning or to trans it, scanning resu es
when you return the icrophone to its clip.
If the radio is scanning and you want to know which channel received the last
broadcast, ove the channel selector slowly through the channels. When the
last active channel is selected, the radio e its a "triple beep."
PRIORITY SCANNING
Priority scanning lets you onitor other channels without issing a call on your
priority channel, which the radio periodically checks for activity even when
scanning has stopped on another channel. Priority scanning works only if the
scan list progra ed is a Priority Scan List, not a Nor al Scan List.
page 16
PUSH-TO-TALK
Pressing the icrophone Push-To-Talk (PTT) activates the radio trans itter.
Refer to FIG-4, page 9. Talk into the icrophone while holding down the PTT.
TX/BUSY LAMP (RED)
The trans it/busy la p flashes if the channel is in use, and stays lighted while the
trans itter is on.
MICROPHONE PLUG-IN
The icrophone cord is connected to the radio front panel via a odular plug. When
you insert the plug, align it as shown below. The cord ay be re oved by pressing
up on the underside of the rubber cover to unseat the plug's lock-tab. The cover is
attached to the plug and should not be pulled off.

OPERATION
DIGITAL QUIET CALL
Digital Quiet Call is RITRONs tradena e for digital coded squelch. DQC works
the sa e as QC, except that a digital code is applied to the broadcast. Radios
progra ed with the correct code "recognize" the inco ing broadcast and
allow the essage to be heard.
PAGING QUIET CALL
General
Paging Quiet Call (PQC) is RITRON's tradena e for its selective paging syste .
Each radio or group of radios ay have a unique PQC code. Any channel that
contains an operating frequency can be progra ed with one of these codes.
(A channel progra ed with PQC ay also contain a QC code.) With a PQC
channel selected and coded squelch on, the radio stays quiet until it receives the
correct PQC code. A ringing tone announces an inco ing call.
Each Paging Quiet Call code is broadcast as a unique pair of audible tones, with
the first tone sent for one second, and the second tone for two seconds. PQC
codes can be originated by a base station paging encoder, a telephone (via a
RITRON RR-454 Repeater Plus/RP-200 syste ), or a RPM obile equipped
with a Touch Tone hand icrophone.
The All-Call Code
Radios operated with PQC respond to a special All-Call code, as well as to their
individual codes. This allows one page to be heard by all "PQC units" on the
channel. The standard RPM obile radio can trans it an All-Call page.
__________________________________________________________________
HOW TO:
Send An All-Call Page -
1) Select a channel programmed with Paging Quiet Call
2) Turn off the radio
3) Press and hold the microphone PTT button while switching on the radio
Keep holding down the PTT A continuous tone will sound
4) Release the PTT when you hear alternating tones
5) Hold down the PTT again and deliver your message
__________________________________________________________________
page 15
WHAT THE RADIO TONES MEAN
The RITRON RPM obile responds to certain instructions by sounding a tone or
series of tones. These tones can tell you whether the radio is working as you expect.
POWER ON/SELF CHECK "OK"
Switch on the radio by rotating the on-off/volu e knob clockwise out of the "click"
position. The obile then runs a quick "self test." When the internal syste checks
verify basic operation, a brief tone sounds that eans the radio is ready to use.
ERROR TONES
However, if the self test detects a diagnostic error, an error tone sounds. One low-
pitched tone eans that the radio icrocontroller is not working as it should.
Alternating tones (the second is lower pitched) indicate that the radio frequency
synthesizer is alfunctioning. If you get one of these essages, turn off the radio
and try again. If the proble continues, consult an authorized RITRON service
facility or the RITRON Repair Depart ent.
Repeating error tones occur if you press the icrophone Push-To-Talk button while
a "Receive Only" channel is selected. The radio will not trans it because a "Receive
Only" channel does not contain a trans it frequency. The error tone repeats until

One low tone sounds and the trans itter auto atically shuts off if you hold the
PTT down continuously for a specified ti e (nor ally, 3 inutes). This trans itter

CHANNEL SELECTION
The RPM obile provides 16 channels, each of which ay be "dealer or factory"
progra ed. The first ten channels appear on the channel display as 0 through 9.
The next six channels are A through F (with b, c and d shown as lowercase letters).
You can ove forward or backward through the channels. Pressing and releasing
the channel button advances the digital display to the next progra ed channel
(any e pty channels are skipped). Pressing and holding the channel button while
toggling the onitor button decreases the channel nu ber. Each ti e you select a
channel, the radio e its a short tone, providing an audible arker. Additionally,
when the channel nu ber "rolls-over" fro the highest to the lowest progra ed
channel nu ber, a "double tone" sounds. This allows you to select channels with-
out looking at the radio (useful if the obile is installed under the driver's seat).

PROGRAMMABLE OPTIONS
IMPORTANT:
If you want to have any progra ing changes ade, contact

QUIET-CALL CODE SIGNALING
_____________________________________________________________________________
HOW TO:
TURN ON QUIET CALL SQUELCH - hang up the microphone
TURN OFF QUIET CALL SQUELCH - take the microphone off-hook or, press and
release the monitor button
TURN OFF QUIET CALL TRANSMIT - program the channel accordingly
_____________________________________________________________________________
Code signaling allows radios to screen out trans issions fro other syste s on
the channel. RITRONs obile co es fro the factory capable of operation with
three co unications industry standard signaling for ats, including Quiet Call
(QC), Digital Quiet Call (DQC) and Paging Quiet Call (PQC). Throughout this
anual, "Quiet Call" refers to the entire fa ily of RITRON signaling for ats (QC,
DQC and PQC), unless specified otherwise.
QUIET-CALL (QC)
Quiet Call is RITRONs tradena e for what the co unications industry calls
sub-audible tone, tone squelch or CTCSS (Continuous Tone Coded Squelch
Syste ).
Your group can use a unique Quiet Call code to avoid the bother of "radio traffic"
fro other licensees. Units with Quiet Call squelch turned on stay quiet unless
they detect the appropriate code on a broadcast.
QC (Quiet Call) channels auto atically trans it a code with your voice when
you press the icrophone PTT. This allows users in your QC group whose
radios are set for coded squelch to hear your essages. Note that other
nearby licensees on your channel can also hear your calls, unless they are
using another code.
page 14
page 11
OPERATION
OPERATING MODES
You can hear calls with the RPM obile in receive ode, and broadcast your voice
with the radio in trans it ode.
RECEIVE
The radio can receive broadcasts while the icrophone Push-To-Talk button is
not being pressed. Whether or not you hear these broadcasts depends upon the
volu e and squelch settings.
You can set the volu e as follows. Press and release the channel select or onitor
button while adjusting the volu e, using the tones as a reference.
SQUELCH
_____________________________________________________________________________
HOW TO:
SQUELCH NOISE - the mobile automatically squelches noise
SQUELCH ALL ON-CHANNEL TRANSMISSIONS EXCEPT THOSE
CARRYING YOUR QUIET CALL CODE - hang up the microphone
_____________________________________________________________________________
Squelch utes the speaker so that interference fro licensees outside of your
network or background noise does not bother the user.
There are two types of squelch used in RITRON obiles. First is carrier
squelch, which quiets the speaker if no on-channel trans issions strong
enough for the radio to detect are present. This eli inates noise. Second is
Quiet Call (coded) squelch. This silences the speaker unless the unit detects
an inco ing essage that carries the sa e Quiet Call code as progra ed
for the channel.
When a radio frequency is shared by several licensees in an area, coded
squelch keeps other licensees' trans issions fro disturbing the users in your
network. When any user lifts his icrophone fro its hang-up clip, coded squelch
is turned off and he can hear all radio traffic on the channel, si ilar to a telephone
"partyline." (This is true unless the channel is progra ed with the Channel
Monitor Lock Out feature; for ore infor ation, see page 18.)
OPERATION
If you press the onitor button again, one beep sounds. The radio will stay quiet
unless paged, and will not detect inco ing essages coded with the channel's
assigned QC code unless you press the PTT. This allows you to answer a page and
carry on a two-way conversation with the caller who trans its your QC code.
After being paged, the radio ust be reset to receive another page. To do this, press
and release the onitor button until one beep sounds.
Pressing the onitor button again causes the radio to sound two beeps. Then, QC
coded calls eant for you will be heard. If the radio receives a page, it will sound an
alert tone. You will be able to hear and reply to QC essages without issing a page.
MOMENTARY MONITOR OPERATION - To onitor a channel progra ed with
PQC, press and hold the onitor button. Three beeps will sound. You will hear any
broadcasts on the channel until you release the onitor button. Then, only QC coded
calls eant for you will be heard.
The radio will sound alert tones if paged, regardless of the squelch status. However,
anyti e you press the onitor or PTT button, or receive a page, PQC squelch is
disabled. In order to quiet the radio until it is paged, switch to another channel and
then back, or turn the radio off and then on.
When you push the onitor button and two beeps sound, you will not hear pages,
but will hear calls that carry your QC code.
NOTE: Earlier odel RPM radios do not sound ultiple beeps when you change the
onitor ode. Also, Quiet Call squelch is auto atically turned on when a channel
is selected.
TRANSMIT
Before trans itting, ake sure that so eone is not already talking on the channel.
Check the trans it/busy la p, which flashes if the channel is busy. This occurs
regardless of any code signaling progra ed. Nor ally, you should not trans it
until the channel is clear.
To trans it, take the icrophone off-hook. Then press and hold the icrophone
PTT (Push-To-Talk) button and talk, with the icrophone two or three inches away.
Speak in a nor al tone, since talking louder will not i prove the listeners reception.
Pressing the PTT button activates the trans itter and lights the trans it/busy la p.
However, pressing the PTT does not activate the trans itter, but produces error
tones instead if: 1) the channel is "Receive Only" (does not contain a trans it
frequency), or 2) the channel is progra ed with the Busy Channel Trans it
Inhibit feature and an inco ing broadcast is present on the channel.

QUIET-CALL (QC)
Quiet Call is RITROAs tradenaAe for what the coAAunications industry calls
sub-audible tone
tone squelch or CTCSS AContinuous Tone Coded Squelch SysteA).
Your group can use a unique Quiet Call code to avoid the bother of "radio traffic"

OPERATION
DIGITAL QUIET CALL
Digital Quiet Call is RITRONs tradena e for digital coded squelch. DQC works
the sa e as QC, except that a digital code is applied to the broadcast. Radios
progra ed with the correct code "recognize" the inco ing broadcast and
allow the essage to be heard.
PAGING QUIET CALL
General
Paging Quiet Call (PQC) is RITRON's tradena e for its selective paging syste .
Each radio or group of radios ay have a unique PQC code. Any channel that
contains an operating frequency can be progra ed with one of these codes.
(A channel progra ed with PQC ay also contain a QC code.) With a PQC
channel selected and coded squelch on, the radio stays quiet until it receives the
correct PQC code. A ringing tone announces an inco ing call.
Each Paging Quiet Call code is broadcast as a unique pair of audible tones, with
the first tone sent for one second, and the second tone for two seconds. PQC
codes can be originated by a base station paging encoder, a telephone (via a
RITRON RR-454 Repeater Plus/RP-200 syste ), or a RPM obile equipped
with a Touch Tone hand icrophone.
The All-Call Code
Radios operated with PQC respond to a special All-Call code, as well as to their
individual codes. This allows one page to be heard by all "PQC units" on the
channel. The standard RPM obile radio can trans it an All-Call page.
__________________________________________________________________
HOW TO:
Send An All-Call Page -
1) Select a channel programmed with Paging Quiet Call
2) Turn off the radio
3) Press and hold the microphone PTT button while switching on the radio
Keep holding down the PTT A continuous tone will sound
4) Release the PTT when you hear alternating tones
5) Hold down the PTT again and deliver your message
page 15
WHAT THE RADIO TONES MEAN
The RITRON RPM obile responds to certain instructions by sounding a tone or
series of tones. These tones can tell you whether the radio is working as you expect.
POWER ON/SELF CHECK "OK"
Switch on the radio by rotating the on-off/volu e knob clockwise out of the "click"
position. The obile then runs a quick "self test." When the internal syste checks
verify basic operation, a brief tone sounds that eans the radio is ready to use.
ERROR TONES
However, if the self test detects a diagnostic error, an error tone sounds. One low-
pitched tone eans that the radio icrocontroller is not working as it should.
Alternating tones (the second is lower pitched) indicate that the radio frequency
synthesizer is alfunctioning. If you get one of these essages, turn off the radio
and try again. If the proble continues, consult an authorized RITRON service
facility or the RITRON Repair Depart ent.
Repeating error tones occur if you press the icrophone Push-To-Talk button while
a "Receive Only" channel is selected. The radio will not trans it because a "Receive
Only" channel does not contain a trans it frequency. The error tone repeats until
you release the PTT.
One low tone sounds and the trans itter auto atically shuts off if you hold the
PTT down continuously for a specified ti e (nor ally, 3 inutes). This trans itter
ti e-out feature ay be turned off or adjusted by authorized service personnel.
CHANNEL SELECTION
The RPM obile provides 16 channels, each of which ay be "dealer or factory"

when the channel nu ber "rolls-over" fro the highest to the lowest progra ed
channel nu ber, a "double tone" sounds. This allows you to select channels with-
out looking at the radio (useful if the obile is installed under the driver's seat).

OPERATION
SCANNING (NORMAL/PRIORITY)
___________________________________________________________________________
HOW TO:
SCAN - hang up the microphone and select the channel that contains your scan list
STOP SCANNING - take the microphone off-hook or, change channels
___________________________________________________________________________
GENERAL
Scanning auto atically lets you listen to broadcasts on different radio channels
(frequencies). The channels to be scanned are kept in a "scan list." This list is
stored in a radio channel. A channel cannot hold both a scan list and a radio
frequency.
HOW SCANNING WORKS
When you select a channel that contains a scan list (and the icrophone is
on-hook), the radio displays the channel nu ber, pauses, sounds a tone, and
then scans, displaying each channel of the scan list in turn. Channels are
scanned in the order that they were progra ed into the list. When a broadcast
is received on a channel being scanned, scanning stops to let you hear co -
unications on that channel. Scanning resu es when the trans ission ends.
The icrophone ust be in its hang-up clip for scan to work. If you lift the
icrophone fro its hang-up clip OR press the channel button, scanning stops.
(Whether scanning stops on the last active channel or on the priority channel is
dealer-progra able.) If you select a channel that contains a scan list and the
icrophone is off-hook, the radio skips to the next channel.
Using the onitor button does not interrupt scanning. Additionally, if you take
the icrophone off-hook to stop scanning or to trans it, scanning resu es
when you return the icrophone to its clip.
If the radio is scanning and you want to know which channel received the last
broadcast, ove the channel selector slowly through the channels. When the
last active channel is selected, the radio e its a "triple beep."
PRIORITY SCANNING
Priority scanning lets you onitor other channels without issing a call on your
priority channel, which the radio periodically checks for activity even when
scanning has stopped on another channel. Priority scanning works only if the
scan list progra ed is a Priority Scan List, not a Nor al Scan List.

PUSH-TO-TALK
Pressing the icrophone Push-To-Talk (PTT) activates the radio trans itter.
Refer to FIG-4, page 9. Talk into the icrophone while holding down the PTT.
TX/BUSY LAMP (RED)
The trans it/busy la p flashes if the channel is in use, and stays lighted while the

MICROPHONE PLUG-IN
The icrophone cord is connected to the radio front panel via a odular plug. When
you insert the plug, align it as shown below. The cord ay be re oved by pressing
up on the underside of the rubber cover to unseat the plug's lock-tab. The cover is
attached to the plug and should not be pulled off.

BUSY CHANNEL DELETE
If a channel in the scan list is so busy that you want to te porarily delete that
channel fro the list, press the onitor button while scanning is stopped on the
channel to be deleted. (The priority channel in a Priority Scan List is an exception,
and cannot be re oved.) The onitor status will not change. The deleted
channel will be skipped in the scan list until you switch channels. You ay delete
ore than one channel in the list.
SPECIAL FEATURES
RECEIVER SQUELCH TIGHTNER FACTOR
This feature reduces distant "co-channel" or other interference for channels
that are not progra ed with Quiet Call. Carrier squelch is set for axi u
sensitivity at the factory, but can be adjusted to ute weak radio signals.
CHANNEL MONITOR LOCK OUT
This function can be progra ed to prevent a radio user fro listening to other
licensees on a shared channel. The trans it/busy la p indicates whether the
channel is busy. Quiet Call or Digital Quiet Call ust be used with this option.
BUSY CHANNEL TRANSMIT INHIBIT
Busy Channel Trans it Inhibit keeps the radio fro broadcasting if the channel
is busy, and is often used with Channel Monitor Lock Out. If you press the
icrophone PTT while the channel is busy with a signal not intended for your
radio (not carrying your Quiet Call code), the Busy Channel Trans it Inhibit
feature sounds a "busy" tone in the speaker and keeps the trans itter off.
REDUCED TRANSMIT POWER
This feature allows for reduced trans itter power on individual channels, which
ight be required by so e FCC licenses.
PAGING QUIET-CALL TRANSPOND
If you receive a page and do not answer within three seconds, this feature
auto atically activates your radio's trans itter and sends an acknowledge-
ent tone to the calling party.
page 17
MONITOR BUTTON
For channels progra ed with Quiet Call, pressing and releasing the onitor
button toggles onitoring on and off. (The icrophone ust be on-hook.) Monitor-
ing lets you hear all radio traffic on the channel. With onitoring off, you hear only
radios that trans it your Quiet Call code. (If the onitor button does not work as
described here, refer to the onitor section on page 13.)
Pressing and holding the onitor button for about two seconds turns off all squelch.
Then ALL signals on the channel AND the noise between broadcasts is heard.
MONITOR LAMP (GREEN)
The onitor la p (see FIG-3 at left) lights when the unit is in onitor ode.
MICROPHONE HANG-UP
The icrophone hang-up controls squelch and onitor functions, through a hook-
switch circuit inside of the icrophone. The icrophone is ON-HOOK when it is
in its hang-up clip, as shown below. The icrophone is OFF-HOOK when it is out
of its hang-up clip.
