General Operation
3.4.3 Direct Channel Select
The direct Channel Select feature is available with the Handheld Control Unit (HHC)
only, and if the Channel Select option switch parameter is programmed. This feature
allows channels to be directly selected using the HHC numeric keys or Up/Down switch.
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 channels 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.
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 using the 0-9 keys, the radio attempts to display the entered number after the
third digit is entered or approximately two seconds after the last key is pressed.
3 To exit this mode and select the entered channel, press the Channel Select switch again.
This mode is also exited automatically without changing the channel after
approximately one 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 if the “Programmed Channels Only On Display” is
not selected. If “Programmed Channels Only on Display” is selected, the wrap around
occurs at Channel 5.
