If you access Menu No. 07 and select ON, you can recall a memory channel to use for either receiving or transmitting. For more information, refer to “Memory- VFO Split Operation” {page 41} under “MEMORY FEATURES”.

The data that you select in steps 1 to 9 except for subtone duration can be stored in memory. Refer to “Split-Frequency Channels” {page 40}.

Note:

When operating through a repeater, over deviation caused by speaking too loudly into the microphone can cause your signal to “talk-off” (break up) through the repeater.

To check the subtone frequency stored in a memory channel, recall the desired memory channel, and access Menu No. 18.
