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 
Digital Keypad Microphone. Please note that a Digital Keypad Mic is required for Direct 
entry.

For direct selection purposes, channels are numbered sequentially starting with the lowest 
zone. Each zone can be programmed with up to 255 channels with up to 2048 channels 
total. 

Proceed as follows to select channels using this mode:

1 Enable the direct Channel Select mode selecting it via the menu or by pressing the 

Channel Select option switch. A single beep sounds when the switch is pressed (if that 
option is enabled). The alias and sequential number of the current channel are 
alternately displayed.

2 Select the desired channel using the channel select knob or directly enter it using the 0-

9 keys. A single beep sounds when the channel is changed (if that option is enabled). 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.
