Here you will find answers to frequently asked questions.

General Questions#

How can I tell if the clock is not synchronized?

The colon(s) will start blinking. The default timeout for indication of state without synchronization is 24 hours.

You can set your own timeout in hours, see chapter Synchronization Settings > Timeout for Indication of State without Synchronization.

How to exit “Power OFF” mode?

To exit “Power OFF” mode, either press push-button PB1L or PB2L, or DISP button on IR remote controller.

How to reset the digital clock to factory settings?

If the clock is fully operational:

Enter the SYSt menu item c1 (see chapter Factory Reset to Default Values > Factory Reset Using Menu). Set the value to 1 and confirm entered value. The FAC inscription will flash on display, and by confirming the clock will reset to default values.

If the clock is not responding or has entered a reset loop:

You need to do the factory reset using push-buttons (see chapter Factory Reset to Default Values > Factory Reset Using Push-Buttons).

Local Time Calculation Questions#

I have digital clock synchronized by a DCF receiver or controlled by a MASTER clock. How to configure the calculation of local time?

Internal timezone table is not used. To show correct local time, set following items to values:

  1. Navigate to SYNC menu item o1 and set it to value A. That ensures the timezone is taken over according to the source of synchronization.

  2. Navigate to SYNC menu item o2 and set it to value 2–9, 11 or A (autodetection). Select your synchronization type.

  3. Navigate to SYNC menu item o4 and disable the MOBALine timezone (set value 0).

  4. Navigate to SYNC menu item o5 and disable the MOBATIME server timezone (set value 0).

  5. Navigate to dISP menu item d2 and set it to value A (automatically set timezone). Time and date is displayed according to source of synchronization including daylight saving time.

I have digital clock controlled by a MASTER clock as MOBALine SLAVE clock and I want to use MOBALine timezones. How to configure the calculation of local time?

To show correct local time, set following items to values:

  1. Navigate to SYNC menu item o1 and set it to value A. That ensures the timezone is taken over according to the source of synchronization and the UTC time calculation is basend on the MOBALine information.

  2. Navigate to SYNC menu item o2 and set it to value 4 (MOBALine synchronization type).

  3. Navigate to SYNC menu item o4 and set your desired MOBALine timezone (values 1–20).

  4. Navigate to dISP menu item d2 and set it to value A (automatically set timezone). Time and date is displayed according to chosen MOBALine timezone including daylight saving time.

I have NTP, PoE, WiFi or WiFi5 variant of digital clock controlled by MOBATIME NTP servers. How to configure the calculation of local time?

To show correct local time, set following items to values:

  1. Navigate to SYNC menu item o1 and set it to value A (automatically set timezone). NTP protocol then uses UTC time.

  2. Navigate to SYNC menu item o2 and set it to value A (autodetection).

  3. Navigate to SYNC menu item o5 and set your desired MOBATIME server timezone (values 1–15).

  4. Navigate to dISP menu item d2 and set it to value A (automatically set timezone). Time and date is displayed according to chosen MOBATIME server timezone including daylight saving time.

I need to display another timezone than timezone provided by the synchronization source. How to set the desired timezone?

To set desired timezone, set following items to values:

  1. Navigate to SYNC menu item o1 and set it to value 0–64 or A (automatically set timezone). Set the value according to the timezone in which the source of synchronization works.

    See chapter Timezones Table.

    Hint

    Value 2 for DCF in west Europe or value A for NTP synchronization

    Note

    Value A only for synchronization working with UTC time.

  2. Navigate to SYNC menu item o2 and set it to value 1–11 or A (autodetection). Select your synchronization type.

  3. Navigate to SYNC menu item o4 and disable the MOBALine timezone (set value 0).

  4. Navigate to SYNC menu item o5 and disable the MOBATIME server timezone (set value 0).

  5. Navigate to dISP menu item d2 and set it to value 0–64 or A (automatically set timezone). Time and date is displayed according to calculation from the UTC time according to desired timezone including daylight saving time.
