Upon start, the cursor appears at the Squelch Mode indicator position of the channel to be edited.

The user may now select the desired Squelch mode from the list, as follows:

step up through available Squelch modes (see table below)

step down through available Squelch modes

accept the entry and return

abandon the entry and exit

The available options are constrained by the operating mode, that is, different Squelch Modes are

available for the analog Operating Modes (wide and narrow) than for the P25 operating mode.

See the table below.
