numeric password must be then be entered as follows.
If an incorrect password is entered, "INCORRECT" is
displayed and it must be re-entered.
DTMF Keypad Models - Enter the password using
the 1-8 keys and then press the Enter (F2) key when
finished. If a mistake is made, the last digit can be
erased by pressing the F1 (Clear) key.
Limited Keypad Models - Select the proper number
for each position by pressing the Up/Down switch.
When the proper number for a position is displayed,
select it and move on to the next position by pressing
the F2 (Enter) key. If the password is less than eight
digits, press F2 twice after the last digit.
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.
3.3 ZONE AND CHANNEL SELECT
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.
