Each push of [PTT] sends a 3-digit code in order toopen the receiving station’s code squelch prior to voice transmis-sion.q Set the operating frequency.• Set the AF and squelch to the desired level as the normal operation.w Push [✱•OPTION] after [A•FUNC] is pushed.• Repeat several times, if necessary.• Code squelch mode is selected.• 100 MHz digit shows “C.”e Select the desired transmit code channel:➥ Push [8•SET] after [A•FUNC] is pushed.➥ Rotate [VOL] to select the desired code channel.➥ Push [#•ENT ] to exit code set mode.r Operate the transceiver in the normal way (push [PTT] to trans-mit; release [PTT] to receive).t To cancel the code squelch, push [✱•OPTION] after [A•FUNC] ispushed.• 100 MHz digit shows “1” when the function is cancelled.Optional UT-108 requiredMRF TX
