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.

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 Channel Select option 

switch is pressed with “Unprogramd” displayed, an error tones sounds, “Invalid” is 
briefly displayed, and the displayed channel does not change.

This radio does not have a squelch control. The squelch level is preset and usually does 
not require readjustment. However, if the squelch level needs to be changed on a 
conventional analog channel, it can be changed using keypad programming if available 
(see Section 5.17 on page 36).

Transmitting can be disabled on each conventional, SMARTNET, SmartZone, and P25 
Trunked channel so that the channel is monitor-only. When transmitting is attempted on a 
receive-only channel, “Rx Only” is displayed and an error tone sounds.
