To scan for the CTCSS tone in use:1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row“e” [TON, -----, TDCH] appears on the display.2. Press the [A](TON) key to activate CTCSS Encoder/De-coder; (the “TSQ” icon will appear on the display)3. Press the [C](TDCH) key to start scanning for the in-coming CTCSS tone.4. When the radio detects the cor-rect tone, it will halt on that tone,and audio will be allowed to pass5. The CTCSS tone detected will bestored as the “current” tone, so it may be used for memorystorage purposes, and you may now exit to normal op-eration.you press the [A](TON) key repeatedly, you will ob-serve “TSQ” (CTCSS Encode/Decode), “DEN” (Digi-tal Coded Squelch, Encode), followed by “DCS”(Digital Coded Squelch, Encode/Decode). One ad-ditional press will disable all repeater-access tonesystems. See the next section for a discussion of DCSoperation.• If the default repeater access tone is not appropriatefor the repeater on which you are operating, it maybe set easily:1. Press and hold the [A](TON) key for one second.This instantly recall Menu Mode No-083 [TONEFREQ].2. Rotate the DIAL knob to select the desired CTCSSfrequency.FM T RANSMISSION3.

With repeater shift activated, you can temporarily re-verse the transmit and receive frequencies by pressingthe [B](REV) key in the Multi Function Row “d” [RPT,REV, VOX]. The “–” icon will blink while “Reverse” shiftis activated. Press the [B](REV) key again to revert tothe “Normal” shift direction.6. On many transceiver versions, the Automatic RepeaterShift (ARS) feature is enabled at the factory. This fea-ture automatically activates the appropriate repeater shiftwhen you are operating inside the designated 144 MHzor 430 MHz FM repeater sub-bands in your country. Ifyou wish to change the On/Off settings for the ARS, useMenu Mode No-002 [144MHz ARS] or Menu ModeNo-003 [430MHz ARS] (see page 54).If your local repeaters need a 1750-Hz bursttone for access (typically in Europe), press andhold in the front panel’s [HOME] key to trans-mit the burst tone (FM mode only).CTCSS TONE FREQUENCY (Hz)67.0 69.3 71.9 74.4 77.0 79.7 82.5 85.488.5 91.5 94.8 97.4 100.0 103.5 107.2 110.9114.8 118.8 123.0 127.3 131.8 136.5 141.3 146.2151.4 156.7 159.8 162.2 165.5 167.9 171.3 173.8177.3 179.9 183.5 186.2 189.9 192.8 196.6 199.5203.5 206.5 210.7 218.1 225.7 229.1 233.6 241.8250.3 254.1
