3-6 5100 ES Models II/III Portable Radio Operating Manual March 2008
General Operation
Proceed as follows to select channels using this mode:
1 Enable the direct Channel Select mode by pressing the Channel Select option switch 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 keys 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> key. To exit without changing the channel, press the <F1> key. 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.
• 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
