   To configure DIP switch position, you need to dismount the front plexiglass. See Single Sided Mounting and Cable connection chapters.

   

2. Set value A in SYNC menu items o1 (Timezone of Synchronization Source) and o2 (Type of Synchronization). Set your desired time zone in dISP menu item d2 (Time Zone of Time and Date).

3. The clock time‑base is synchronized by incoming pulses in normal operation of the slave line.

4. Set current date and time in tIME menu according to MASTER clock with accuracy of ±30 seconds (or ±15 seconds, or ±0.5 second respectively).

5. The colon flashes in 2 second interval.

6. After 2–3 minutes are the clocks synchronized with the MASTER clock. The colon is permanently lit during the display of time.

7. In case of the line fault, the clock displays the right time information based on its own quartz time base. When the normal operation of the line resumes, the clock synchronizes with the incoming pulses.
