INTRODUCTIONGENERALRITRON's JMX_141 handheld is a small, programmable two-way radio, designed to operate over one of two sub-bands. The low split covers 148-161 MHz and the high covers 161-174 MHz.This handheld features push-button operating controls, with the Push-To-Talk and Channel buttons on one side ofthe radio. The On / Volume Up and Volume Down / Off, volume and monitor controls are on top.Each radio can be “dealer or factory” programmed to contain a unique set of operating frequencies and options.Separate RX and TX Quiet Call (CTCSS) tones can be programmed per channel. Transmitter deviation can beprogrammed on a per channel basis.InspectionEach radio package should include a radio, antenna, rechargeable battery pack, belt clip and any optionalaccessories ordered. Examine the equipment immediately after delivery and report any damages to yourshipping company.Model IdentificationThe JMX-141 model, serial number and FCC Identification are displayed on a label located on the back of theradio beneath the belt clip.FCC REGULATIONSLicensingThe FCC requires the radio owner to obtain a station license for his radios before using them to transmit, but doesnot require an operating license or permit.The station licensee is responsible for ensuring that transmitter power; frequency and deviation are within thelimits specified by the station license. The station licensee is also responsible for proper operation andmaintenance of the radio equipment. This includes checking the transmitter frequency and deviation periodically,using appropriate methods.Safety StandardsThe FCC (with its action in General Docket 79-144, March 13, 1985) has adopted a safety standard for humanexposure to radio frequency electromagnetic energy emitted by FCC regulated equipment. RITRON followsthese safety standards, and recommends that you observe the following guidelines:•DO NOT hold the radio such 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, two to three inches away while talkinginto the microphone.•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.
BATTERY CAREThe handheld is powered by a rechargeable battery, which fits into the radio case (see FIG-1).CHARGINGThe battery pack can lose its charge during storage and shipment, and should be fully charged before the radio isused. Thereafter, the battery should be charged overnight after each day of use, to ensure peak radioperformance for the next day. Using the cube charger (model BC-A), the battery should charge completely in 12hours.Note: A new battery must be cycled (charged and discharged) several times before it will reach its maximumcharge capacity.To charge the battery using a RITRON cube charger - plug the charger cord into the smaller of the two jacks ontop of the radio. Then plug the cube into a 110 VAC outlet. The green lamp lights while the battery is charging,and should go off only when the cube is unplugged.Two charger contacts, visible through the bottom of the radio case, allow the battery to be charged using anoptional RITRON drop-in charger (model BCPS-FS). The battery pack may be charged inside or outside of theradio case.To charge the battery using a drop-in charger (model BCPS-FS) - plug the drop-in charger into a 110 VAC outlet.Set the portable or battery into the charger. Each battery contact must rest on a charger contact pin.Typically, a battery pack’s service life is one year. To ensure maximum service life, follow these guidelines:•Do not discharge a battery that is already “run down.” If the battery cannot power your radio, recharge thebattery.•Do not overcharge a battery. The standard battery should not be left to charge continuously.•Before storing a battery, charge it for 16 hours. Thereafter, charge the battery for 16 hours once every 30days.With daily use and recharging, a battery’s service life is about one year. It is time to purchase a new battery:1) When the radio’s transmitter coverage decreases or does not work at all.2) When the radio quits working after just a few hours of use, even with a full overnight charge.3) When the battery is more than two years old. The date of manufacture is stamped on every battery. The firsttwo digits indicate the year, the last two digits the week.
BATTERY CAREBATTERY REPLACEMENTTo take the battery out of the radio, remove the battery door pictured in FIG-1. Use the pull-tab to remove thebattery.Slide the replacement battery into the radio case. Make sure the spring contacts are inserted between the batteryand paper insulator. The contacts must not touch the radio PC board.PRECAUTIONS•Use only RITRON-supplied chargers; other chargers might cause fire, explosion, or other damage to theradio.•Do not "fast-charge" a brand new battery pack. Otherwise, the battery might be damaged.• Once the battery has been charged fully using the normal rate, the fast rate may be used thereafter.•Do not fast-charge a battery pack that is fully charged. This can shorten battery life.•Do not charge or replace a battery in an explosive atmosphere. Contact sparking can ignite an explosion.•Do not dispose of a battery in fire. An explosion might result.•Do not charge the battery in temperatures colder than about 45°F. Electrolyte leakage can occur and ruin thebattery.•Charging in temperatures above approximately 95°F will not harm the battery, but can reduce its chargecapacity.Fig. 1Battery Replacement
DESCRIPTION OF CONTROLS AND CONNECTORSAntennaThe flexible antenna radiates and receives radio signals. Before using the radio, be sure the antenna base isthreaded fully into the radio’s antenna bushing.VHF and UHF antennas are not interchangeable. Use only the antenna type packaged with the radio. A VHFantenna is pictured in FIG-2. (The UHF antenna is smaller in diameter.)On/Volume UpThis button switches on the radio, then increases the volume if you continue to press.Off/Volume DownThis button decreases the volume, then shuts off the radio if you continue to press.Channel SelectPressing this button selects the next channel. When the maximum number of channels is reached and you pressthis button, the radio resets to channel 1.SpeakerThe speaker allows you to hear calls on your channel.Push-To-Talk ButtonThe PTT activates the transmitter, and must be held down while you talk into the microphone. Release the PTTbutton to receive.MicrophoneThe microphone converts your voice into electrical impulses, which are carried with your broadcast to receivingradios. Hold the radio about two inches away and talk into the microphone while transmitting. Shouting does notimprove the listener’s reception.Audio Accessory JackThis jack connects speaker audio to optional accessories, such as a remote speaker/microphone or an earphone.For accessories that have a two-plug connector, the smaller plug is inserted into the charge jack.This jack is also used to program the radio using the optional PC programming kit.Charge JackThe battery may be charged through this jack using a standard RITRON wall socket charger cube.This jack also connects microphone audio to the optional remote speaker/microphone.Battery Access (Case Bottom)The battery door on the case bottom may be removed to access the battery. (Refer to the battery section of thismanual.)Drop-in Charger ContactsTwo charger contacts in the bottom of the JMX-141 radio case allow the battery pack to be charged using anoptional RITRON drop-in charger (model BCPS-FS).Jack CoverThis rubber cover seals out dust and moisture, etc. Snap the cover into the audio accessory and charge jackopenings when the jacks are not being used.
DESCRIPTION OF CONTROLS AND CONNECTORS CHON OFF/HOLDVOLUMEBelt Clip InstallationIf you are going to attach the belt clip to the handheld, follow these instructions:1) The belt clip is fastened to the radio case back with the Philips head screw provided.

OPERATIONOn-off/VolumeTo switch on the radio - press the on/volume up button.To adjust the volume - press the volume up button until you reach the desired level. You should hear noise andany broadcasts on the channel.To turn off the radio - press and hold the off/volume down button until a beep sounds.To determine whether the radio is on - press the volume down button. If the radio is on, noise or activity on thechannel is heard.ReceiveTo hear calls from other users - adjust the volume as desired. The radio can receive broadcasts while the Push-To-Talk button is not being pressed. Whether or not you hear these broadcasts depends upon the squelchsettings.There are two types of squelch used in the JMX-141 portable. First is carrier squelch. This lets you hear allbroadcasts on your channel strong enough for the radio to detect, and silences noise. Second is one of theselective signaling or “tone squelch” formats available on the JMX-141. This allows you to screen out “on-channel” broadcasts that do not carry the correct code programmed for the radio.Note: It is possible that the beginning of a call might be missed while the radio is in battery saver mode. If thishappens, ask the caller to repeat his message.MonitorTo monitor the channel - press one of the volume control buttons. When you press the volume up or the volumedown button, squelch turns off and all radio traffic on the channel (and noise) sounds in the speaker.Selective Signaling SquelchTo activate tone squelch - simultaneously press both of the volume buttons. Hold for a second or two beforereleasing. When tone squelch is turned on, the handheld sounds one beep. When carrier squelch is on, the radioemits a "double beep."Note: If you continue to hold down the volume buttons after the beep (or double beep), the radio will start beepingrepeatedly. This means that squelch is turned off. Release the buttons. To restore squelch, press and hold bothof the volume buttons until the radio sounds a beep or double beep.Battery SaverThe handheld has a "battery saver" feature that conserves battery power. The battery saver constantly checksthe radio's transmitter, receiver and controls for activity. If a number of seconds pass without the receiverdetecting a call, and without the user operating a control, this feature removes power from most of the radio.During this "off-time," any activity restores full power. Every few fractions of a second, the battery saver appliespower to the receiver, checking for broadcasts. It is possible that the first part of an incoming call might gounheard before activity is detected and power restored. If this happens, the caller can repeat his message. Once"radio contact" is made, normal unhurried conversation can follow.
OPERATIONTransmitTo transmit - hold down the Push-To-Talk button and, with the radio a couple of inches away, talk into themicrophone. Speak in a normal tone, since talking louder will not improve the listener’s reception.Channel SelectionTo read out present channel - press and release the channel button. The radio will beep a number of times equalto the present channel number.To change channels - press and release the channel button within one second after a previous press. The radiowill beep a number of times equal to the new channel number. If the highest channel number is selected and youpress the channel button, the radio will reset to channel 1. A one-channel radio will beep only once when youpress the channel button.WHAT THE RADIO TONES MEANThe handheld responds to certain instructions by sounding a beep or series of tones. These tones can tell youwhether the radio is working as you expect.Error Tones in Receive ModeSynthesizer Unlock – A beep every second indicates the radio frequency synthesizer is malfunctioning. Incrementchannels until you arrive back on channel. If beeping persists synthesizer is faulty, frequency is outside ofauthorized range or EE memory is corrupt. Turn off the radio and try again.Low battery - If a beep occurs every minute then the battery is low. Recharge or replace the battery. The radiowill receive with a low battery but may shut down during transmit.Shut down – The radio will shut down when the battery voltage drops below a predetermined “dead battery” levelto protect EE data.Error Tones in Transmit ModeSynthesizer Unlock – A beep every second while PTT is pressed indicates the radio frequency synthesizer ismalfunctioning. If beeping persists synthesizer is faulty, frequency is outside of authorized range or EE memory iscorrupt. Turn off the radio and try again.Time-out-Timer alert – A rapid beeping occurs when 1 minute of transmission has elapsed. Transmission isterminated. Beeping will stop and the radio will return to receive mode when PTT is released.Shut down – The radio will shut down when the battery voltage drops below a predetermined “dead battery” level.Channel SelectWhen the channel button is pressed, the radio beeps a number of times equal to the channel number selected.Tone SquelchWhen you press and hold both Volume buttons at the same time, a single beep will sound to indicate that tonesquelch is on. A "double beep" means that carrier squelch is on.
OPERATIONOPERATIONTROUBLESHOOTINGIf you have trouble operating the handheld, review the radio controls and operation sections. If you think the radiois malfunctioning, check the table below.Problem Possible SolutionsGENERALThe radio does not work at all.

(Note 7.)Notes1) Try a battery pack from a working radio. If the radio in question works with that pack, the original battery issuspect. Charge the suspect battery as recommended in this manual. Then, if the charged original batterycannot power the handheld, try charging again with another charger. If the battery still doesn’t hold a charge,the pack should probably be replaced. However, if the battery appears to be good after you try the secondcharger, the first charger might be faulty. If you think that an accessory is not operating properly, contact yourdealer or RITRON. (Radio accessories come with a 90-day limited warranty.)2) Reception can often be improved by moving a short distance. This effect is more noticeable inside ofbuildings. The range of these portables equipped with a standard battery pack is about two miles (line-of-sight).3) If your radio does not detect calls from other radios on the channel, turn off tone squelch. (Press both Volumebuttons at the same time - a double beep means that tone squelch is off.)4) If you want to hear a call, you must select a channel that is programmed to receive the caller’s transmitfrequency. If you want to call another unit, you must select a channel that is programmed to transmit theother radio’s receive frequency. However, if you use a repeater, your channel must be programmed to workwith the repeater’s transmit and receive frequencies. (A radio channel can hold two separate operatingfrequencies, one for Receive, the other for Transmit.)5) Maximum power drain occurs while the radio transmits, so don’t hold down the Push-To-Talk button morethan necessary. Battery power is used while the handheld is left on to receive calls. If practical, switch off theunit.6) In extreme cold, a battery’s charge capacity is greatly reduced. If you use the radio in very cold weather,periodically warm the portable underneath your coat if possible. An optional remote speaker/microphonewould allow you to keep the radio under your coat while transmitting and receiving.7) In order for radios to communicate using Quiet Call, they must be programmed with the same tone code.Each code is unique, and your radio will respond only to the code programmed.Press and hold both volume buttons at the same time. A single beep means that tone squelch is on. Adouble beep means that tone squelch is off.
PROGRAMMING THE RADIOEach JMX-141 may be programmed to operate on up to 4 channels. The JMX-141 may be programmed using itsPush-to-Talk switch or an optional RITRON programming kit.PTT (PUSH-TO-TALK) PROGRAMMING allows you to program any channel to one of the radio frequencieslisted in Table 1 and any Quiet Call code listed in Table 2. The radio will transmit and receive on the programmedtable frequency and QC code.PC PROGRAMMING allows you to program any frequency within the band and channel spacing of the radiomodel. This method also lets you customize the handheld with optional operating features.PTT (PUSH-TO-TALK) PROGRAMMINGPlacing the Radio in PTT Programming Mode1. Turn off the radio by pressing the Volume Down button until the “radio off” prompt sounds.2. Press and hold the PTT button.3. While holding the PTT button, press and hold the Volume On button until a rapid beeping is heard in thespeaker.4. Release the PTT and Volume On buttons. A series of five beeps will sound in the speaker indicating that theradio is in PTT program mode.Note: If the radio will not enter PTT program mode, this feature has probably been turned off using the optionalPC programming kit.How to Find Out What Is Already Programmed1. Place the radio in PTT programming mode as described above.2. Press the Channel button to select the radio channel you would like to read out.3. Press the Volume Up button.4. The radio will sound a series of beeps, pause, and then begin another series. Four series of beeps will beheard, with each series representing a digit. The number of beeps in a series is equal to the digit. (10 beeps= the digit 0)5. Write down each digit while the radio pauses. List the digits in the order that you hear them.6. The first two digits represent the frequency as shown in Table 1.7. The second two digits represent the QC (CTCSS) tone frequency as shown in Table 2.Note: If you are unable to read out a channel, it has probably been programmed using the PC programming kitto a frequency not contained in Table 1.
PROGRAMMING THE RADIOPTT Programming the RadioFour valid digits must be entered for the radio to accept PTT programming. The first two digits entered is thefrequency code from Table 1, followed by the two digits for the QC code from Table 2.1. Place the radio in PTT programming mode as described above.2. Press the Channel button to select the radio channel you would like to program.3. Enter the first digit by pressing the PTT button the number of times equal to the digit’s value.(To enter the digit 0, press the PTT ten times.)4. Pause after the digit is entered, a tone will sound indicating that the digit has been accepted.5. Enter the second, third and fourth digits using the same method as the first digit.6. Press the Volume Up button to enter the new channel programming. The radio will sound a confirmation toneto indicate that programming has been accepted.PTT Programming MistakesInvalid Entries An error tone means that you tried to save an invalid entry. No programming changesare made in this case. A triple tone will sound next indicating that the radio is still inprogramming mode, and ready for an entry.PTT Entry Mistakes If you press the PTT five times when you intended four, for example, or if you just losecount, do not press the Volume Up button to store the entry. Instead, start over byturning the radio off and placing the radio in programming mode again.Return To Normal OperationAfter you finish programming, turn the radio off and then on again. The radio will beep when it is ready for normaloperation.
