General Operation
3.7
Setting Squelch
The user can program a menu item, or function button, for squelch adjust. While on a
conventional analog channel without emergency or scan active, the user can select the
programmed button or menu item for squelch adjust. The current squelch setting will
show on the display. Using the up and down buttons on the portable radio, the user can
adjust the squelch setting to a desired level from -7 to +7. Increasing the value t7
causes the squelch to open sooner for weaker signals while decreasing towards -7 has the
opposite effects. Pressing the select button will store the new squelch setting and return
the user to the main display.
The squelch level is preset and may not require readjustment. However, if the squelch
threshold needs to be changed on a conventional analog channel, it can be changed in the
same way as though using keypad programming if available. The squelch level is preset
during alignment. If the keypad programming feature is available (see Section 5.15), the
squelch threshold can be changed by the user on each conventional analog channel.
Note
The Keypad Programming feature is available to Federal Government users only.

Transmit Disable
Transmitting can be disabled on each conventional, SMARTNET, SmartZone, and P25
Trunked channel so that the channel is monitor-only. When transmitting is attempted on a
receive-only channel, “Rx Only” is displayed and an error tone sounds. This is
programmed for each radio.
3.9
Radio Operating Modes
Each selectable channel can be programmed for the conventional (analog or Project 25
digital), SMARTNET/SmartZone, or Project 25 digital trunked operating mode. For
example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a
SMARTNET channel, and so on. More information on these modes follows.
Note
All operating modes utilize certain functions that are activated/deactivated by pressing
and holding a particular key/button or switch. The “hold” interval is preset. When
instructed to “press and hold”, do so until the desired action occurs. For other operations
(not specified “press and hold”) only momentary pressing is required.
The user has the ability to use two different timers for Emergency mode (Conventional
system) - one to enable and one to disable emergency mode, preventing accidental
