OWNER’S MANUAL FRS RADIO 21-1845 INTRODUCTION With RadioShack’s base station FRS radio, you can stay in constant communication with your family 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 the channel you selected and you do not want to hear that person, select another channel, or use the QUIET feature. You can talk with a person who has a FRS radio if both radios are tuned to the same channel and QUIET code. Your radio has auto-squelch, which means you will not hear anything on a channel unless someone is transmitting nearby on the same channel. You can turn off auto-squelch to hear weaker, distant transmissions. You can connect an optional speaker/microphone and earphone to the radio. The VOX operation 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 FRS channels 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 from other systems in the area operating on the same frequency. Built-in Modulation Limiter Circuit ---- automatically adjusts for a wide variety of voice levels to ensure an understandable transmission. External Earphone and Microphone ---- Let you transmit or receive message by pressing or releasing 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 the transceiver’s back panel. Serial Number_______________________ Your transceiver might cause TV or radio interference even when it is operating properly. To determine whether your transceiver is causing the interference, turn off your transceiver. If the 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 CONTROLS 1. Volume Control. Rotate this control rightwards to turn on your radio and adjusts the volume, until you get a comfortable listening level. 2. CALL You can cause a ringer sound on all radios tuned to the same FRS channel and/or the privacy code as your radio. To send a page, press and hold down the CALL button. 3. Talk button To talk, hold down the Talk. Speak into the microphone in a normal tone of voice when the TX indicator lights. When you finish speaking, release the Talk button. 4. VOX Button To active/deactivate VOX function, press and release the VOX button. When VOX on led indicator 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 to transmit until the user finishes. Then, the unit will go into the receive mode. 5. VOX Sensitivity Rotary 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 Indicator It will light when you transmit. 7. Power LED Indicator It will light when the unit is turned on. 8. VOX LED Indicator When VOX on led indicator lights, it indicates the VOX function is activated. 9. MON Button To hear everything happening on a channel, including weak transmission, hold down MON button. Release the MON button to turn the auto-squelch back on. 10. External Mic/Spk Jack Connect an optional speaker/microphone or earphone in this jack. 11. Power Jack Just plug the station into the DC outlet of included DC adapter, then connect the adapter to a standard AC outlet. 12. Fixed Telescopic Antenna Adjust 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 using these two arrays of dip switches. SETTING CHANNEL FREQUENCIES AND CTCSS CODES On the station bottom, you will find two arrays of dip switch. These switches are used to set the channel frequency, and CTCSS code. Setting for 38 CTCSS Code The first array of 6-digit dip-switch is used to set 38 CTCSS codes. Please find below table for setting. CTCSS CTCSS Dip Switch Dip Switch Code Freq.(Hz) Setting Code Freq.(Hz) Setting 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 without CTCSS 67.0 71.9 74.4 77.0 79.7 82.5 85.4 88.5 91.5 94.8 97.4 100.0 103.5 107.2 110.9 114.8 118.8 123.0 127.3 000000 000001 000010 000011 000100 000101 000110 000111 001000 001001 001010 001011 001100 001101 001110 001111 010000 010001 010010 010011 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 131.8 136.5 141.3 146.2 151.4 156.7 162.2 167.9 173.8 179.9 186.2 192.8 203.5 210.7 218.1 225.7 233.6 241.8 250.3 010100 010101 010110 010111 011000 011001 011010 011011 011100 011101 011110 011111 100000 100001 100010 100011 100100 100101 100110 Setting for Channel Frequencies The second array of 4-digit dip switch is used to set any one of the 14 channel frequencies.

OPERATION 1. 2. 3. 4. 5. 6. Plug the station with 9VDC 500mA adapter for power. Rotate volume control to turn on the radio. Press the MON button and adjust to a comfortable listening level. Press the Talk button to transmit or use VOX option for hands-free. The TX indicator lights green. Select the desired channel and/or QUIET code. To receive, simply release the Talk button. In VOX mode, the unit will receive when the user transmits speaking. 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 the same QUIET code as your radio.
