> TIME ZONE SET
Use the UP ARROW or DOWN
ARROW Buttons to scroll through the
dropdown menu.
Set the TIME ZONE SET to local time.
Setting the TIME ZONE SET utilizing
the Time Zone Set Table (figure 17-1)
will provide the unit with accurate local
time within the Time Zone that the unit
is operating.
The AML Pro maintains a Real Time
Clock (RTC), that can be automatically
synchronized to Global Positioning
System (GPS) time. RTC is the user's
local time while GPS is referenced to
Universal Time Coordinated (UTC)
based in Greenwich, England.
There are 24 Time Zones. Find the
zone in which the unit will be operating
(see figure 17-1) and enter the time
off-set value from the Time Zone Set
vs. Local Time Table. After the Time
Zone Off-set value is entered and
saved, the RTC will be updated the
next time a GPS signal is acquired.
For those parts of the world with
a nonstandard off-set (30 or 45
minutes), the local clock time
synchronizing can be disabled by
entering a value of 24 into the TIME
ZONE SET.
The AML Pro does not automatically
shift the off-set for Daylight Savings
Time, add one(1) to your Time Zone
Set to adjust the time manually. This
time change will have to be re-entered
manually to come back from Daylight
Savings Time. The TIME ZONE SET
will have to be reset if the AML Pro
is transferred for use in other time
zones.
