following:

SELECT SYNCH CLOCKS

CLK[1] &/OR CLK[2]

Note: CLK[2] appears on the LTR8-512 and LTR8-512M only

Since only one of the clock circuits may have lost power, you can choose to re-sync CLOCK1,

CLOCK2 or both.

Press [1] to turn on or off this display:

ADVANCE CLK1

Press [2] to turn on or off this display (you will see this option only if your clock is setup

for 2 Clock Systems.):

After choosing which clock circuits to sync, press [#].

If your clocks are synchronous types (01, 03, 06, 18, 19 & 22), they can only advance to the

start of the nearest hour and will then wait for the Master Clock to catch up. If your clocks are

impulse types, then you will see

Enter the time shown on the secondary clocks that have lost time, then press [#]. You will see

PRESS [#] TO EXECUTE

To sync the secondary clocks, press [#], or press [*] to cancel. Your impulse clocks will

advance to your LTRx-512’s time

NOTES:

1. The Clock Sync function does not support Clock Types 14, 15 or 24

2. When a Power-On Clock Recovery or user-initiated clock sync occurs, your LTRx-512 will

not accept other commands to start clock synchronization

3. You can cancel Power-On Clock Recovery or user-initiated clock synchronization by

choosing Clock Types again through function [2]=SELECT CLOCK CTL.
