Channel Mode (MR)
The use of Channel (MR) mode is dependent on having previously programmed in some channels for use. To learn how to
program channels, reference Section 4, Subsection G Programming in this manual.
Once the channels are programmed and ready, the [UP] and [DOWN] buttons can be used to navigate between channels.
Note: If you have channels programmed with Transmit power set to Low, you can use the [POUND] button to momentarily
switch over to high power if you're having trouble getting through.
