General Operation
Seq. Ch. No.
Proceed as follows to select channels using this mode:
1 Enable the direct Channel Select mode by pressing the Channel Select option with 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 buttons 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> button. To exit without changing the channel, press the <F1> button.
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 buttons, 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.
