How To Set The Date And Time On An LTR-512 Master Clock

The LTR-512 Series Master Clock's time accuracy is important for secondary clock synchronization as well as to ring external signalling devices at specific times. On LTR8-512 and LTR8-512M Master Clocks, Masterlink Software can be used to keep the time synchronized. The LTR8-512M can call the National Institute of Standards and Technology to synchronize its time once a week.

1. Press [#]  [0]  [#].
2. Enter the Administrator Password.
3. Press [#]  [1]  [#].
4. Enter the numbers for the month, date and year (4-digit year) and [#].
   
   If today's date is August 31, 2011, the key sequence is
   [0]  [8]  [3]  [1]  [2]  [0]  [1]  [1]  [#]
5. Enter the day of the week and [#].

1. Enter the time, using either 12-hour or 24 hour format, then press [#].
2. Press [0] for PM or [1] for AM, as needed.
3. Press [#] to save the changes.

When completed the LTR-512 Master Series will return to the date and time. Seconds will start when the display has returned. On LTR8-512 and LTR8-512M Master Clocks, if using Masterlink, Update Master Time from the software.
