(p. 34)➥While holding down [PTT], hold down either the [Y]or [Z] for 1 or 2 seconds.■ DTCS encoder (Only TX)The DTCS encoder superimposes the selected DTCScode over your transmitted signal.q Push [FUNC](M), and then push [SET](8) to enter the Setmode.w Set the DTCS code and polarity, in the same way youset the DTCS squelch. (p. 30)• You can set the DTCS transmit and receive polarity, butthe DTCS encoder affects only transmit.e Push [# ENT] to exit the Set mode.r Push [FUNC](M), and then push [TONE](1) severaltimes, until both “D ” and “ ” appear.• The DTCS encoder activated.(88.5 Hz is selected)• The “Repeater tone” item in the Set modePush , and then push several timesto turn ON the DTCS encoder.DTCS encoder (Only TX)5 REPEATER AND DUPLEX OPERATIONS
