Operating Your Radio
Time Adjust
All VHF, DSC, and GPS activities use a 24-hour clock and Universal Coordinated Time (UTC)
which was formerly known as Greenwich Mean Time (GMT). Time Adjust uses your built-in
GPS to gather time input. Time Adjust will allow the radio to display the time as Local time
or UTC time. For time input to be converted to local time, you need to enter the hour offset
of your local time zone from Greenwich. (See world city time zone chart on page 88). You
can also choose to have the time displayed in a 12 or 24 hour format.

1. Enter the Settings menu and scroll to TIME ADJUST
with the Up/Down soft keys or the Up/Down channel
buttons.

to change the setting for your local time zone.

EXIT soft key to EXIT without making changes to the Local
Time Zone setting.
