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
alternately displayed.
2. Select the desired channel using the Up/Down keys
or directly enter it using the 0-9 keys (if available).
If using the 0-9 keys, the radio attempts to display
the entered number after the 3rd digit is entered or
approximately 2 seconds after the last key is
pressed.
3. To exit the this mode and select the entered channel,
press the Channel Select switch again or the F2 key.
To exit without changing the channel, press the F1
key. This mode is also exited automatically without
changing the channel after approximately 1 minute
of no activity.
NOTE: The Channel Select function should probably
not be assigned to a number key because pressing that
key to select a channel then exits the select mode.
Other features of this mode are as follows:
•
When using the Up/Down keys, wrap-around to the
lowest zone/channel occurs after the last channel in
the highest programmed zone is displayed and vice
versa. For example, if Zone 1/Channel 5 is the
highest programmed channel, wrap-around occurs
after Zone 1/Channel 16 is displayed.

When an unprogrammed channel is displayed, the
sequential channel number and "Unprogramd" are
alternately displayed.
•
If an invalid channel number is entered using the
0-9 keys, or the F2 or Channel Select option switch
is pressed with "Unprogrammed" displayed, an
error tones sounds, "Invalid" is briefly displayed,
and the displayed channel does not change.
•
The rotary Channel Select switch may not correctly
indicate the selected channel after direct channel
selection is used. However, if this switch is enabled
and rotated, it selects the channel it is indicating. For
example, if the switch index is pointing to channel 3
and channel 15 of the current zone is being
displayed, rotating it to channel 4 selects channel 4
of the current zone.
•
If the rotary Channel Select switch is enabled, the
radio always powers up on the channel it is
selecting.
If it is disabled, the radio can be programmed to
power-up on the last selected or home channel
number of the last selected or home zone. With the
"Last Zone"/"Home Channel" configuration, the
programmed home channel number of the last active
zone is selected. If it is not programmed, "Unpro-
grammd" is displayed. With earlier models, the last
selected channel is displayed when powering up on
the last selected zone, and channel 1 is displayed
when powering up on the home zone.
3.4 LOW BATTERY INDICATION
3.4.1 GENERAL
NOTE: If the radio contains encryption keys and is not
programmed for infinite key retention, be sure to reat-
tach a battery within approximately 30 seconds to
prevent the loss of these keys (see following).
A low-battery condition is indicated by the
icon in the display. The battery should be recharged or
replaced as soon after this indication appears. Once
this indication appears, it stays on until power is
cycled.
