1OWNER’S MANUALFRS RADIO21-1845INTRODUCTIONWith RadioShack’s base station FRS radio, you can stay in constant communication with yourfamily throughout your home. In addition, they’re great for office use as well.Your radio has 14 channels and 38 different QUIET codes. If someone else is using thechannel you selected and you do not want to hear that person, select another channel, or usethe QUIET feature. You can talk with a person who has a FRS radio if both radios are tunedto the same channel and QUIET code.Your radio has auto-squelch, which means you will not hear anything on a channel unlesssomeone is transmitting nearby on the same channel. You can turn off auto-squelch to hearweaker, distant transmissions.You can connect an optional speaker/microphone and earphone to the radio. The VOXoperation brings you convenient hands-free use.Your transceiver has these features:Selective Channel and QUIET ---- You can select the channel from one of the 14 FRSchannels and one of the 38 QUIET by using two arrays of dip switches.PLL Controlled Circuitry ---- provides accurate and stable channel selection.QUIET (Continuous Tone Control Squelch System) ---- helps reduce interference fromother systems in the area operating on the same frequency.Built-in Modulation Limiter Circuit ---- automatically adjusts for a wide variety of voicelevels to ensure an understandable transmission.External Earphone and Microphone ---- Let you transmit or receive message by pressing orreleasing Push-To-Talk button on the headset or use VOX option for hands-free operation.Fixed Telescopic Antenna ---- Let you have a better performance of communication.We recommend you record your transceiver’s serial number here. This number is on thetransceiver’s back panel.Serial Number_______________________
2Your transceiver might cause TV or radio interference even when it is operating properly. Todetermine whether your transceiver is causing the interference, turn off your transceiver. Ifthe interference goes away, your transceiver is causing it. Try to eliminate the interference by:• Moving your transceiver away from the receiver.• Contacting your local RadioShack store for help.FUNCTION AND LOCATION OF THE CONTROLS1. Volume Control.Rotate this control rightwards to turn on your radio and adjusts the volume, until you get acomfortable listening level.2. CALLYou can cause a ringer sound on all radios tuned to the same FRS channel and/or the privacycode as your radio. To send a page, press and hold down the CALL button.3. Talk buttonTo talk, hold down the Talk. Speak into the microphone in a normal tone of voice when theTX indicator lights. When you finish speaking, release the Talk button.
34. VOX ButtonTo active/deactivate VOX function, press and release the VOX button. When VOX on ledindicator lights, it indicates the VOX function is activated. When VOX function is activated,the unit transmitter will automatically be opened when the user speaks. It will continue totransmit until the user finishes. Then, the unit will go into the receive mode.5. VOX SensitivityRotary this control to adjusts the VOX sensitivity. When there is too much background noise,it is better to turn this control leftwards to select Lo sensitivity.6. Transmit LED IndicatorIt will light when you transmit.7. Power LED IndicatorIt will light when the unit is turned on.8. VOX LED IndicatorWhen VOX on led indicator lights, it indicates the VOX function is activated.9. MON ButtonTo hear everything happening on a channel, including weak transmission, hold down MONbutton. Release the MON button to turn the auto-squelch back on.10. External Mic/Spk JackConnect an optional speaker/microphone or earphone in this jack.11. Power JackJust plug the station into the DC outlet of included DC adapter, then connect the adapter to astandard AC outlet.12. Fixed Telescopic AntennaAdjust antenna will let you have a better performance of communication.13. Two arrays of dip switches (at the bottom)Let you select one channel from 14 FRS channels and one of 38 QUIET frequencies by usingthese two arrays of dip switches.
4SETTING CHANNEL FREQUENCIES AND CTCSS CODESOn the station bottom, you will find two arrays of dip switch. These switches areused to set the channel frequency, and CTCSS code. Setting for 38 CTCSS CodeThe first array of 6-digit dip-switch is used to set 38 CTCSS codes. Please findbelow table for setting.CTCSS CTCSSCode Freq.(Hz)Dip SwitchSetting Code Freq.(Hz)Dip SwitchSettingwithout CTCSS 00000001 67.0 000001 20 131.8 01010002 71.9 000010 21 136.5 01010103 74.4 000011 22 141.3 01011004 77.0 000100 23 146.2 01011105 79.7 000101 24 151.4 01100006 82.5 000110 25 156.7 01100107 85.4 000111 26 162.2 01101008 88.5 001000 27 167.9 01101109 91.5 001001 28 173.8 01110010 94.8 001010 29 179.9 01110111 97.4 001011 30 186.2 01111012 100.0 001100 31 192.8 01111113 103.5 001101 32 203.5 10000014 107.2 001110 33 210.7 10000115 110.9 001111 34 218.1 10001016 114.8 010000 35 225.7 10001117 118.8 010001 36 233.6 10010018 123.0 010010 37 241.8 10010119 127.3 010011 38 250.3 100110
5 Setting for Channel FrequenciesThe second array of 4-digit dip switch is used to set any one of the 14 channelfrequencies. Please find below table for setting.Dip Switch Setting Channel Frequency (MHz)0000 FRS 1 462.56250001 FRS 1 462.56250010 FRS 2 462.58750011 FRS 3 462.61250100 FRS 4 462.63750101 FRS 5 462.66250110 FRS 6 462.68750111 FRS 7 462.71251000 FRS 8 467.56251001 FRS 9 467.58751010 FRS 10 467.61251011 FRS 11 467.63751100 FRS 12 467.66251101 FRS 13 467.68751110 FRS 14 467.71251111 FRS 14 467.7125C. OPERATION1. Plug the station with 9VDC 500mA adapter for power.2. Rotate volume control to turn on the radio. Press the MON button and adjust to acomfortable listening level.3. Press the Talk button to transmit or use VOX option for hands-free. The TX indicatorlights green.4. Select the desired channel and/or QUIET code.5. To receive, simply release the Talk button. In VOX mode, the unit will receive when theuser transmits speaking.6. To turn off the transceiver, turn volume to the left until a click is heard.Note: You can only communicate with another radio that is using the same channel and/or thesame QUIET code as your radio.
