• Channel Up: Press to increase the channel by 
step. Press and hold to continuously scroll through the
channels. Unprogrammed channels will be skipped.
Note: Your dealer can program the "Roll Over" (default) or
"Dead End" feature. When Roll Over is programmed, pressing
Channel Up while you are at the highest channel will cause the
transceiver to select the lowest channel, and begin the increase
cycle again. When Dead End is programmed, pressing
Channel Up while you are at the highest channel will not
change the channel number.
• Delete/Add: Press to remove an undesired channel
from the scan sequence or to add a desired channel to
the scan sequence. See "SCANNING" on page 7.
• Emergency Call: Press and hold this key for the time
required (which is pre-programmed by your dealer)
to enter Emergency mode. If "Emergency Channel
Display" is activated by your dealer, the emergency
channel name will appear on the display and the TX LED
(red) will light.
• Home Channel: Press to change from the current
channel to your home channel. Press again to return to
the previous channel, from your home channel.
• Invert Display: Press to invert both segmented displays
(the icons do not change). This allows channel numbers,
names, and other information to be easily read when you
use the transceiver in such a way as to have the display
upside down.
• Key Lock: Press to lock most of the keys on the
transceiver. Press again to unlock the keys. See "Key
Lock" on page .
