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.

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 18), 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 24), 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.

3.2.1  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.
