GENERAL OPERATION

ming data is read or written, it must be entered after
performing those functions. 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.
This password can be changed only by the
programmer (see Section 4 of the 5100 Service
Manual). It cannot be changed by the user. If it is lost,
all programming must be erased to make the trans-
ceiver operational again. This is done using the
“EEPROM Erase” function of the PCTune program
(see Section 6.3.3 of the 5100 Service Manual). This
password is displayed by the programmer when data is
read. However, data cannot be read (or written) when
the transceiver is locked, so the lost password cannot
be determined using the programmer.
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 3.8.5.
Zone Select
The front panel Up/Down switch changes and
displays 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 (with Flash code 1.7.0 or later). The “A” posi-
tion then selects Zone 1, “B” Zone 2, and “C” Zone 3
(if applicable).
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). This knob may be
disabled when direct selection is used to prevent
confusion because it then may not correctly indicate
the selected channel.
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.
Proceed as follows to select channels using this
mode:
1. Enable the direct Channel Select mode by pressing
the Channel Select option switch or selecting the
“Chan Selct” menu parameter. The alias and
sequential number of the current channel are alter-
nately displayed.
* This feature requires 51xx operating (Flash) software
1.5.0 or later and PCConfigure 1.17 or later.
