After installing your SecureSync unit, and connecting all references and network(s),
verify that power is connected, and wait for the device to boot up.
Note: SecureSync does not have a power switch. When the unit is
plugged in, the power will be on (unless you have an additional con-
dition, such as your unit has been halted).

Observe that the front panel illuminates The time display will reset and then start
incrementing the time.

3.
Check the front panel status LED indicators:
The Power LED should be lit (not flashing).
The GNSS LED will be either OFF or flashing HEARTBEAT, since syn-
chronization has not yet been achieved.
The Alarms LED light should be OFF (startup behavior) or HEARTBEAT
(acquiring fix behavior). A FAST blinking pattern would indicate the unit
requires attention.
For additional information, see "Status LEDs" on page4 and "Status Monitoring via Front
Panel" on page279.
4.1.2 Shutting Down the Unit
Shutting down SecureSync by interrupting the AC power supply is acceptable and will not
damage the unit.
