2.4 GENERAL OPERATION
2.4.1 INTRODUCTION
The following section describes features available
with both trunked and conventional operation.
Features unique to conventional channels are
described in Section 2.6, and features unique to
SMARTNET/SmartZone channels are described in
Section 2.7.
2.4.2 TURNING POWER ON AND SETTING
VOLUME
Power is turned on and off by the On-Off/Volume
switch on the top panel. When power is initially turned
on, an alert tone sounds and the indicator on the top
panel flashes green. If a SMARTNET/SmartZone
channel is selected, the zone alias is then displayed
followed by the unit ID (see Section 2.7.2). The
selected channel is then indicated.
To turn power off, turn the On-Off/Volume knob
counterclockwise until a click occurs. The display may
remain on for a few seconds after power is turned off.
It is recommended that power not be turned back on
again until the display is blank.
The relative volume level can be determined by
noting the position of the index on the On-Off/Volume
knob. To enable a reference tone for setting the
volume, proceed as follows:
•
If key press tones are enabled (see Section 2.4.11), a
short tone sounds when front panel keys are pressed.
•
If a conventional channel is selected and the
Monitor option switch is programmed (see Section
2.6.4), 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.
2.4.3 POWER-UP PASSWORD
General
The power-up password feature prevents unau-
thorized use of the transceiver. When it is enabled by
system operator programming, an eight-digit password
must be entered to make the transceiver operational
each time power is turned on. Passwords can be
entered even if the keypad is locked (see Section
2.4.6). The default password is eight zeros
(00000000). Refer to Section 3.7 for more informa-
tion on passwords.
If this feature is enabled, proceed as follows to
unlock the radio:
1. Turn radio power on and when “LOCKED” is dis-
played, enter the eight-digit numeric password
using the keypad. As each digit is entered, a dash is
displayed. If an incorrect digit is entered, press the
CLR
key and re-enter the entire password.
2. When all eight digits have been entered, press the
ENT
key. If the password is correct, the display
indicates normal zone and then channel informa-
tion. If an incorrect password is entered,
“LOCKED” is again displayed.
Changing Password
The current password can be changed as follows:
1. The locked mode must be selected to change the
password, so cycle power if necessary to display
“LOCKED”.
2. Enter the old eight-digit password and press the
#
key (not
ENT
). If the correct password is entered,
“NEW PSWD” is displayed.
3. Enter the new password and press
ENT
. The pass-
word is changed.
2.4.4 BACKLIGHT
The backlight for the display and keypad can be
manually turned on by pressing the Backlight option
switch if it is available. The backlight can also be
system operator programmed to automatically turn on
