GENERAL OPERATION
16
•
If a conventional channel is selected and the
MON
(Monitor) option
switch is programmed (see page 26), pressing that switch unsquelches/
squelches the receiver and either voice or background noise is heard. If
a SMARTNET/SmartZone channel is selected, the receiver cannot be
manually unsquelched.
Backlight
The backlight for the display and keypad can be manually turned on
and off if the
BKLHT
option switch is programmed. Pressing this switch
cycles between the Bright, Dim, and Off modes. If this switch is not
programmed, the backlight is fixed in one of these modes.
Option Switches
All five push-button switches on the front panel are programmable
for various functions. If your radio is programmed with both conven-
tional and SMARTNET/SmartZone channels (see page 23), these option
switches can be dealer programmed to control a different set of functions
for each channel type. For example, a switch could select Monitoring
when a conventional channel is selected and Private calls when a
SMARTNET/SmartZone channel is selected.
The available functions in each mode are indicated in the tables on
pages 10 and 11. If the functions controlled by your switches are not indi-
cated in these tables or by the key cap label, consult your dealer to deter-
mine how your switches have been programmed. If no option switch has
been programmed to control a particular function, that function may not
be available or may be in a fixed mode.
Channel and Zone Selection
Channel Select
To change the selected channel, rotate the Select switch. The
selected channel alias (name) is indicated on the top line of the display.
With conventional channels, the channel number or frequency may also
be displayed (see “Display Mode Selection” on page 25).
