numeric password must be then be entered as follows.

displayed and it must be re-entered.

DTMF Keypad Models - Enter the password using

3.2.2  PASSWORD FEATURES

An enhanced password scheme allows up to four 

power-on (user) passwords, download and upload 
passwords, and a master password to be programmed. 

The current User password can be changed if the 

“Set User Password” option switch or menu param-
eter is programmed. Selecting this function displays 
prompts for entering and confirming a new password. 
It is recommended that a number key not be used for 
this function because the password mode is exited if 
that key is pressed to enter a number. Refer to Section 
9 for more information on passwords.

The selected zone and channel are selected and 

displayed as follows. For more information on zones 
and channels, refer to Section 3.9.5.

Zone Select

The front panel Up/Down switch briefly displays 

and changes the alias of the current zone. When not in 
special modes such as the menu mode, pressing either 
the top or bottom part of this switch once displays the 
alias of the current zone. Then quickly pressing it 
again changes the selected zone up or down. The 
rotary A/B/C switch on the top panel can also be 
programmed for zone select. The “A” position then 
selects Zone 1, “B” Zone 2, and “C” Zone 3 (if appli-
cable).

After the highest programmed zone is displayed, 

wrap-around to the lowest programmed zone occurs 
and vice versa. The selected zone is also displayed 
briefly on power up. If the selected zone alias needs to 
be displayed continuously, it must be programmed as 
part of the channel alias.

Channel Select 

Channels are selected by the rotary 16-position 

switch on the top panel. The alias (identification) for 
the selected channel/group is displayed continuously 
during normal operation.

When an unprogrammed channel is selected, 

“UNPROGRAMD” is displayed and a tone sounds (if 
tones are enabled). When conventional channels are 
selected and the Display Information option key or 
menu parameter is programmed, either the channel 
frequency or alias can be displayed (see Section 5.9).

The channel selector knob can also be disabled by 

programming. Channels must then be directly selected 
as described next (if applicable). It may be desirable to 
disable the channel select knob when direct selection 
is used in order to prevent confusion since the channel 
knob then may not indicate the selected channel.

The radio can also be programmed so that the 

channel select control is also be disabled by the 
Keypad Lock feature (Section 3.6) similar to the 
volume control described in Section 3.1.3. 

Direct Zone/Channel Selection

The direct Channel Select feature is available if 

the Channel Select option switch or menu parameter is 
programmed. This feature allows channels to be 
directly selected using the DTMF keypad numeric 
keys (DTMF models only) or Up/Down switch (all 
models). 

For direct selection purposes, channels are 

numbered sequentially starting with the lowest zone. 
Each zone can be programmed with up to 16 channels, 
so Zone 1 channels are numbered 1-16, Zone 2 chan-
nels 17-32, and so on as shown below. For example, 
Zone 1/Channel 16 is selected by Channel 16, and 
Zone 2/Channel 16 is selected by Channel 32.
