2) Time and Date - The current date and time in Greenwich Mean
Time or Universal Time Coordinated (UTC, GMT, or Zulu time).
It is critical that these fields not be set to local time – they
must
reflect UTC. Proper Datalink performance depends on accurate
setting of UTC time in these fields.
3) Time Zone - Selects your local offset from Greenwich Mean
Time. For example, in the eastern US you would select either
“UTC – 4 Hours” during Daylight Savings Time, or “UTC – 5
Hours” during Standard Time.
4) Current Time and Date settings - Displays the time/date values
currently being reported by the GPS and Datalink as well as the
Local and UTC values that are currently set in the EX500/EX600.
Note: You cannot change Local time directly – you must first set the
GMT time correctly and then choose the correct Time Zone.
5) Menu Timeout - Sets the amount of time that the key labels are
displayed from the following choices (in seconds): Never, 2, 5,
10, 20, 30, 40, 50, 60. If “Never” is selected, the key labels do not
time out.
