Notes

If you switch on DUPLEX at Channel 1 to 8, 41 to 48, then your radio will receive signal from these channels but send at Channel 31 to 38, 71 to 78 to repeaters nearby, and the repeaters will send signal at the original channel. So do not use channel 31 to 38, 71 to 78 directly with simplex mode.
Channel 5 and 35 is for Emergency use only!
General conversation channels: 9, 10, 12-21, 24-30, 39, 49-60, 64-70, 79, 89.
