GENERAL OPERATION
SECTION 3 GENERAL OPERATION
3.1 TURNING POWER ON AND SETTING
VOLUME
3.1.1 POWER ON/OFF
Power is turned on and off by pressing the On-
Off/Volume knob. When power is turned on, the radio
goes through a self test. When that is successfully
completed, the unit ID is briefly displayed (except
when a conventional analog channel is selected), a
tone sounds (if tones are enabled), and the radio is
ready for normal operation. If “ENTER PSWD” is
briefly displayed, refer to the next section.
The radio can be programmed* so that one of the
following combinations are selected at power up:
•
Last Zone/Last Channel
•
Last Zone/Home Channel
•
Home Zone/Last Channel
•
Home Zone/Home Channel
The Home Zone and Channel are prepro-
grammed. With the “Last Zone”/“Home Channel”
configuration, the programmed home channel number
of the last active zone is selected. If this channel
number is not programmed in the active zone, “Unpro-
gramd” is displayed. With earlier models, the last
selected channel is displayed when powering up on the
last selected zone, and the home channel is displayed
when powering up on the home zone.
NOTE: In dual control configurations (front mount
radio with remote control unit), the power switches at
both control points must be off for power to turn off.
3.1.2 SETTING VOLUME LEVEL
The relative volume setting can be determined
using a reference tone as follows:
•
If the key press tones are enabled (see Section 4.5 on
page 20), a short tone sounds when an option switch
is pressed or the Select switch is pressed or rotated.
•
If a conventional channel is selected, take the micro-
phone off-hook and if someone is talking, voice may
be heard. If the
MON
(Monitor) option switch is
programmed (see Section 5.3 on page 26), pressing
it unsquelches the radio and either voice or back-
ground noise is heard. If a SMARTNET/SmartZone
or P25 trunked channel is selected, the radio cannot
be manually unsquelched.
3.2 POWER-UP PASSWORD
3.2.1 GENERAL
The power-up password feature prevents unau-
thorized use of the radio by requiring that an 8-digit
password be entered to make it operational. This
feature is enabled or disabled by programming.
When it is enabled, “ENTER PSWD” is briefly
displayed when power is turned on, the eight-digit
numeric password must be entered by pressing and
rotating the Select switch. If an incorrect password is
entered, “INCORRECT” is displayed and it must be
re-entered.
3.2.2 PASSWORD FEATURES WITH LATER
MODELS
With later revised models (with firmware 1.24.1/
2.2.1/3.2.1 or later), an enhanced password scheme
allows up to four power-on (user) passwords, down-
load and upload passwords, and a master password to
be programmed.
The current User password can be changed if the
“
PW CHG
” option switch is programmed. Selecting
this function displays prompts for entering and
confirming a new password. Refer to Section 10 for
more information on passwords.
3.2.3 PASSWORD FEATURES WITH EARLY
UNREVISED MODELS
With early unrevised models (with earlier firm-
ware than listed above), only one power-on password
is available, and it cannot be changed by the user. This
*
This feature requires radio firmware 2.2.1/3.2.1 or
(ARM) 1.24.1 or later.
