INTRODUCTION THANK YOU FOR CHOOSING RITRON FEATURES Congratulations on your purchase of the JMX “D-Series” radio. Your new radio is the result of Ritron’s 25+ years of designing, manufacturing, and supplying reliable, professional wireless communication products. Ritron wireless products will improve the operation, safety, and profitability of any organization by providing instant voice communications between employees throughout the workplace. This manual covers the JMX “D-Series” radios.
INTRODUCTION • Channel scanning (except JMX-111D). The Scan channel allows scanning of all channels programmed into the radio. The Scan channel can be turned On and Off through Field programming, • Low battery alert. The radio will sound a low battery alert tone when your battery is running down to allow you time to recharge or change your battery. • Weather Channel. VHF models can be programmed to receive your local NOAA weather radio broadcast.
CONTROL & OPERATION I ANTENNA The flexible antenna radiates and receives radio signals. Screw the antenna base all the way into the threaded bushing on top of the radio. NOTE: Use only the type of antenna furnished with the radio. VHF and UHF antennas are not interchangeable. 2 ON / VOLUME UP To switch the unit On, press the On / Volume Up button; the speaker will emit a turn on beep. If the radio turns on to the Scan Channel it will emit the Scan Beep.
OPERATION 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 Beep. 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 volume level is displayed as a number between 0 through 9.
OPERATION 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.
OPERATION 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.
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 Channel, refer to page 9. 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.
OPERATION ADDITIONAL FEATURES • The JMX “D-Series” handheld radios have other features available through PC programming. See your Ritron dealer or contact Ritron directly for PC programming of these options. Monitor Lock Out can be set 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 to prevent transmitting when a broadcast is present on the receiver that does not carry the correct code.
NOAA WEATHER RADIO SELECTING YOUR LOCAL NOAA WEATHER FREQUENCY VHF models of the JMX “D-Series” radio can hear weather forecasts from the National Weather Service which are broadcast on one of the seven NOAA weather frequencies. The radio is shipped from the factory without a NOAA frequency selected. Before using any of the NOAA weather features on your VHF radio you must first select the local NOAA frequency. 1. Follow the steps in FIG-4 at right to place the radio into the Weather Frequency Select mode.
RADIO PROGRAMMING IMPORTANT To talk to other users in your group, all radios must be set to the same frequency and Interference Eliminator codes. HOW TO READOUT FIELD PROGRAMMED FREQUENCY & TONE CODES In our example channel 3 of a JMX-446D radio is programmed to operate on the “Brown Dot” frequency of 464.500 MHz (Frequency code “04”) with 100.0 Hz tone (Tone code “12”). 1. Place the radio into Program / Readout Mode by following the instructions in FIG- 6 at left.
RADIO PROGRAMMING HOW TO FIELD PROGRAM FREQUENCY & TONE CODES 7. Enter the 1st digit of the frequency code by clicking the PTT button until the channel display shows the desired number. Pause - the radio will sound a low tone and show a hyphen across the center of the display to indicate that it is ready to accept the next digit. 8. Enter the 2nd digit of the frequency code by clicking the PTT button until the channel display shows the desired number.

BATTERIES FIG-7: BATTERY ACCESS AND INSTALLATION BATTERY ACCESS DOOR (A) DOOR LATCH 4. Use the Pull-tab to pull the battery pack out of the case (D). 5. Insert the replacement battery pack, being certain to POSITION IT RELATIVE TO THE CASE AS SHOWN IN (D). Push the Battery Pack in as far as possible. 1. Hold the radio as shown above (A). 6. Replace the Battery Access Door. Secure it by closing the Door Latch as shown in (B). 2. Use your thumbnail to open the Door Latch, as shown below (B). 7.
BATTERIES CAUTION: Use only RITRON-supplied chargers; using other chargers may cause fire or explosion, or otherwise damage the radio. 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.
!! CAUTIONS – ALL RADIOS !! OBSERVE CAUTION IN THE FOLLOWING ENVIRONMENTS TO MAXIMIZE THE LIFE OF YOUR RADIO EQUIPMENT: MOISTURE: JMX “D-Series” 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 battery and other components.
SPECIAL APPLICATIONS HOW TO FIELD PROGRAM TWO-TONE ENCODE CODES THIS FEATURE AVAILABLE ON JMX-144D / 444D / 446D MODELS ONLY 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 your radio for 2-Tone encode operation.
TROUBLESHOOTING NOTES 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.
FCC LICENSE REQUIRED FCC REGULATIONS HOW TO OBTAIN AN FCC RADIO LICENSE 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.
