Follow

Model: Automatic Setting Analog Clock

Symptoms

All or some of the symptoms may be present.

  • Second hand is advancing in 5 second increments and pausing, advancing 5 seconds and pausing. Applies to firmware version prior to V3.0.

  • Second hand is advancing in 2 second increments and pausing. Applies to firmware V3.0 and greater.

Cause

Clock has not received a signal from a Transmitter for three consecutive days or clock has low battery power.

Note

Analog Clock signal search frequency:

At six pre-scheduled times a day, at 2:01 AM/PM, 6:01 AM/PM, and 10:01 AM/PM clock time (not the actual time of the day), a clock's receiver turns on to search for a Transmitter signal to receive a time update, starting with the previously stored channel number. If a signal is not received from the first channel, the clock scans all channels to search for a signal.

If a clock's second hand is stepping (continuously advancing and pausing), its receiver only turns on at 2:01 AM & PM. The stepping indicates the clock has not received a time signal from the Transmitter for three consecutive days.

If the Transmitter is broadcasting, a manual search can be initiated locally at the clock. Press and immediately release the button on the back of the clock or remove it's batteries for 10 seconds, stretch the battery tabs in the battery holder out slightly to apply more pressure to the battery contacts, and re-insert the batteries.

Analyze

  • Identify scope of clocks experiencing issue - single clock or all clocks/clocks in specific area.

    Single clock:

    All clocks/clocks in specific area

Solution

  1. Single clock - check battery expiration date and replace batteries.

  2. More than one clock - verify Transmitter status and resolve error state.
