OPERATION
page 3
ON-OFF / VOLUME ADJUST
To turn on the radio - press the On/Volume Up button.
The radio will emit a beep and the channel display will
light. If the radio turns on to the Scan Channel it will emit
the Scan eep. The radio will always turn on to the
channel that was selected when it was last turned off.
To adjust the volume - press the volume up or volume
down button until you reach the desired level. The vol-
ume level is displayed as a number between 0 through 9.
To turn OFF "beeps" - speaker beeps can be disabled
through field programming to provide a silent mode of
operation (ideal for security applications), only your
incoming calls will be heard on the speaker. Refer to
page 10 for How to Field Program Radio Options.
When speaker beeps are disabled only the low battery
indication and 2-Tone decode ring tone, if enabled, are
retained.
To turn off the radio - press and hold the Off/Volume
Down button until a two tone "turn-off beep" is heard.
For instant turn-off, press the PTT button while holding
the Off/Volume Down button.
CHANNEL SELECTION
To change channels - press and release the Channel
Selector button. The radio will emit a short Channel beep,
increment the channel, and the Channel Display will
show the new operating channel. If the highest channel
number is selected and you press the Channel Selector
button, the radio resets to channel 1 and the Channel
beep is heard on the speaker.
If the Scan Channel is selected - the radio will emit the
Scan eep and the Channel Display will rapidly flash the
channel 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 eep, then
scanning will resume as normal.
If the Weather Channel is selected - on a VHF radio the
Channel beep will be heard and the display will light a
single segment that indicates which of the seven NOAA
frequencies is monitored. See the "NOAA Weather
Radio" section on page 6 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 two standard squelch modes that can be used
in the JMX "D-Series" portable.
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 JMX. This allows you to
screen out on-channel broadcasts that do not carry
the correct code programmed for the radio.
When Carrier or Tone Squelch is selected by the
user, all channels will operate in that mode. The JMX
"D-Series" radio will operate in tone squelch mode
when it is first turned on.
To activate Tone Squelch or Carrier Squelch and to
Monitor the channel - simultaneously press both the
volume buttons and hold briefly before releasing.
 If the radio 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 radio.
 If the radio 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.
Note: It is possible that the beginning of a call
might be missed while the radio is in
battery saver mode. If this happens, ask
the caller to repeat the message.
If you are unable to activate Carrier Squelch - the radio
has been optionally programmed for Monitor Lockout.
See your Ritron dealer or contact Ritron directly to
disable this option.

QC TONE CODES
(Interference Eliminator Codes)
Tone codes help filter out the "chatter" of others
that share your radio channel. hen you operate
on a frequency with a tone code, you screen out
most interference. This allows you 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.
TRANSMIT
Normally, you should not transmit until the channel is
quiet. This can be determined by monitoring the channel
prior to transmitting.
To transmit - hold down the Push-To-Talk button and with
the radio four 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
conserve battery, minimize radio frequency exposure,
and allow others to use the channel.
RADIO ALERT TONES
The handheld responds to certain instructions by sound-
ing a beep or series of tones. These tones can tell you
that the radio is working as you expect.
Power On/Sel Check OK
When it is first turned on, the radio runs a quick self
test to confirm basic functions. When complete the radio
will emit the channel beep and the Channel Display will
show the operating channel. The radio is then ready to
use.
OPERATION
Error Tones
However, if the self test detects a diagnostic er-
ror, an error tone sounds. The error tone
indicates the radio 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 radio. In this case, recharge the
battery. If you cannot correct a problem, consult an
authorized Ritron service facility or Ritron.
Channel Select
When the Channel button is pressed, the radio will emit
a short Channel beep, increment the channel, and the
channel display will show the new operating channel.
Scan Channel (except JMX-111D)
When the Scan channel is selected by pressing the
Channel button, the radio will emit the Scan beep and
begin scanning.
Tone Squelch
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.
Recharge Battery Alert
As the battery voltage approaches the minimum
required operating voltage the radio will emit a series
of short beeps to alert the user that the battery will
soon need recharging. Once the battery charge drops
below the required operating voltage, the radio emits
a long, low tone and turns itself off. If you turn the
radio back on, it will beep again and shut itself off.
Recharge the battery.
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. The
radio automatically switches to receive mode.
OPTIONAL ALERT TONES
JMX "D-Series" models JMX-144D/446D/444D 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.
Receive Squelch Tone
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 radio 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 radio is ready for you to begin
talking.
FIG-2: TRANSMIT / BUSY LAMP
A Transmit / Busy
Lamp in the upper
left corner of the
Channel Display
is lit whenever
the transmitter is

OPERATION
SCAN CHANNEL OPERATION
Channel scanning allows you to listen to broadcasts
on your radio channels. The JMX "D-Series" (except
JMX-111D) will scan all channels programmed into the
radio with the exception of the NOAA Weather Chan-
nel, refer to page 6.
How Scanning Works
Using the Channel Selector button, select the Scan
Channel. The radio 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
radio will stop scanning to let you hear communica-
tions on that channel. After the transmission has
ended the radio will pause before it resumes scanning
to allow you time to respond.
When transmitting from the Scan Channel, the
handheld will go to the last channel on which a signal
was received, then transmit. After you release the
PTT the radio will pause to allow time for a response,
and then resume scanning.
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 radio 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 radio is turned off, or when the
radio channel is changed using the Channel Selector
button. Channel 1 cannot be blocked.
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.
Priority Scanning (Optional)
The JMX-144D/446D/444D radios can be option-
ally programmed for priority scanning. Priority
can allows you to periodically monitor a Priority
Channel, even if the radio has stopped on another
channel. This will prevent missed calls on the pri-
mary operating channel when in scan mode.
With Priority can 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 radio can be programmed to transmit only
on the Priority Channel when scanning, if
desired.
 The radio can be programmed to sound a
Priority Channel Beep whenever the radio
receives on the Priority Channel when scanning.
ee your Ritron dealer or contact Ritron directly for
PC programming of this option.

BATTERY MAINTENANCE & CONDITIONING
Due to the extended run time of the JMX "D-Series" radios, some users
may never fully discharge the battery pack during normal use Achieve
maximum battery life by fully discharging the battery periodically to
condition it
After exposing the battery pack to many cycles of not fully discharging it
before recharging, the radio may exhibit reduced battery capacity This
reduced capacity is evident when, after several hours of use, battery
voltage drops while the radio is transmitting, causing the radio to emit a
low battery warning tone
Condition battery packs by the following procedure as either a
preventive measure, or if you suspect reduced capacity:
TO CONDITION THE BATTERY PACK:
1. Use your radio throughout a normal work day without charging
2.  Press and hold the On/ Volume Up and Volume Down/ Off buttons
simultaneously for 8 seconds to place the radio in "no squelch"
mode
 Release both buttons when you hear the radio beep rapidly; it will
then emit a loud "rushing" noise Press On/ Volume Up to maximize
this noise
3. Put the radio away in a secure place (possibly a desk drawer),
where nothing can press against the buttons to accidentally turn it
off or cause it to transmit Allow the radio to run until it shuts off
when the battery is completely discharged A typical battery pack
may require up to 8 hours to completely discharge
4. When the radio has shut off, charge it overnight for 12-14 hours
The battery will be ready for use with renewed capacity
NOT : A new battery must be charged and discharged several times
before it can reach its maximum charge capacity
CAUTION: Use only RITRON-supplied cha ge s; using othe cha ge s may cause fi e
o explosion, o othe wise damage the adio.
CHARGING
The JMX "D-Series" radio is powered by a rechargeable battery pack Because the battery pack
loses its charge during storage and shipment, fully charge it before first use To ensure peak
radio performance for the next day, charge the battery overnight after each day of use It
completely charges in about ten hours
TO CHARGE THE BATTERY WITH A RITRON CUBE CHARGER
Plug the charger cord into the charge jack (marked "CHG") on top of the radio Then plug the
cube into an 110 VAC outlet The green lamp lights while the battery is charging, and should
go out only when the cube or cord is unplugged
TO CHARGE THE BATTERY WITH A RITRON DROP-IN CHARGER
Two charger contacts, visible through the radio case bottom, permit charging the battery with
an optional Ritron drop-in charger The battery pack may be either removed from the radio case
for charging, or charged inside the radio case
Each drop-in charger comes with a spacer to permit charging a "spare" battery while the radio
is being used
To use the drop-in charger, plug it into a 110 VAC outlet Set either the radio with the battery
installed, or only the battery with the battery spacer, into the charger Refer to the illustration
in Optional Accessories, opposite Each battery contact must rest on a charger contact pin
NOT :
Batte y pack life ave ages one yea . Follow these guidelines to maximize se vice life:
 CONDITION battery packs once a month as directed in Battery Maintenance & Conditioning, at
right
 CONDITION batteries that are run down
 CHARGE batteries for 16 hours before storage, and for 16 hours once a month thereafter
 DO NOT overcharge batteries Unplug the cube charger after 16 hours to avoid overcharging
 DO NOT charge batteries in temperatures colder than about 45°F Charging batteries in
temperatures above 95°C does not harm them, but can reduce charge capacity

HOW TO FIELD PROGRAM TWO-TONE ENCODE CODES
THIS FEATURE AVAILABLE ON JMX-144D/446D/444D MODELS ONLY
For special applications, it is possible to se yo r Ritron portable radio or base station
for remote control applications; s ch as opening or closing a gate remotely (see Rit on
GateGua d at www.ritron.com/gg_04.pdf). This application req ires yo to program
yo r radio for 2-Tone encode operation.
The ser can field program each channel with one of the 9 p e-set 2-Tone Codes
specified in Table 5. These codes correspond to field programmable 2-Tone Codes
available in the RITRON 6-Series OUTPOST Callbox. In o r 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-pro-
gram the channel to the desired Frequency Code and Tone Code and then SAVE
the entry by pressing the On/ olume Up button, then you may enter your 2-Tone
Code, remember you must also SAVE this entry by pressing the On/ olume Up
button.
1. Refer to Table 5 to determine the 2 digit, 2-Tone Code(s) yo wish
to program into each specific channel.
2. Follow the instr ctions in Fig 6, page 7 to place the radio in the
Program/Reado t Mode.
3. Using the channel b tton and the LED display on the radio, select
the channel n mber yo want to program a 2-Tone Code into.
4. Enter the 1st digit of the 2-Tone code by clicking the PTT b tton
ntil the program display shows the desired n mber. Pa sethe
radio will so nd 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 b tton
ntil the program display shows the desired n mber. Pa sethe
radio so nds a low tone and will show a hyphen across the
display.
2-TONE CODE
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  , 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 ode 04 (464.500 MHz) with
Tone ode 12 (100.0 Hz) and 2-Tone encode Code 94.

messages.
TROUBLESHOOTING
1.  Try a battery pack from a working radio. If the radio in question works
with that pack, the original battery is suspect.
 Charge the suspect battery as recommended in this manual. If this
original battery cannot power the radio, try charging it again with
another charger. If the battery still doesn't hold a charge, the pack
should probably be replaced.
 If the battery appears to be "good" after using the second charger,
the first charger may be faulty. Contact a dealer or itron about an
accessory that is not operating properly.
2.  eception can often be improved if you relocate by a short
distance. This effect is more noticeable inside buildings.
 The range for SST radios is about two miles, line-of-sight.
. 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.
4.  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.
5.  Maximum power drain occurs when the radio transmits, so don't
hold down the PTT more than needed to transmit.
 Battery power is used while the handheld is left on to receive calls. If
practical, switch off the unit.
6.  Battery capacity is greatly reduced in extreme cold.
 To use the radio in very cold weather, periodically warm it under
your coat if possible.
 An optional remote speaker/ microphone allows keeping the radio
under your coat while transmitting and receiving.
7.  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.
