To enter hexadecimal characters A - F:
Each long press of the [2] key toggles the
right most character from A to B to C, then
back to A.
Each long press of the [3] key toggles the right most character from D
to E to F, then back to D.
To enter a ‘letter’ after another ‘letter’ or number, first enter any
number, then toggle it with long [2] or [3] key presses.
The digital equivalent of carrier squelch is achieved by programming
the hexadecimal receive NAC to $F7E. The radio will unmute when a
digital signal with any NAC is detected.
Press [ENT] to store and return to the next value.

SELECTIVE
SQUELCH MODE
This field is the Receiver Squelch Mode for
Channel 1. This setting is only used if the
receive mode selected was Digital or Mixed,
or if User Channel Guard is activated. The
upper part of the display will show ‘PRG RX’.
Available modes are Normal and Selective.
Normal squelch opens on a matching NAC and ANY Talk Group ID or
Individual Unit ID.
Selective squelch requires the correct NAC and the correct Talk Group
ID, and for Unit-to-Unit calls, requires a matching Individual ID.
If the Squelch Mode is correct, press the [FCN] key to advance to the
next field.
If a different Squelch Mode is desired, press the [PRI] key to toggle
the setting. Then press the [ENT] key to store this setting and
automatically advance to the next field.
