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.

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.

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.
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.
