If you have one or a few locks that are not showing the correct time, the first step is to reset a clock. Do not reset a clock if a Transmitter is in an error state.
For any of the below symptoms, you will want to perform the steps detailed in this article to resolve the issue.
The clock's second hand is continuously advancing and pausing (stepping)
This indicates the clock has not received a time update for three consecutive days.
The clock time is not correct or stuck at a random time.
This can be due to a loss of power or low battery level.
The clock's hour and second hands are stuck at 12:00 or not moving
This may be due to a manual hand alignment check was performed. This is performed by holding down the button located on its backside for three seconds.
When a clock is reset, it will turn on its receiver and searches for a signal from a Transmitter to receive a time update.
Verify the Transmitter is currently broadcasting or reset the clock between 40 minutes after the current hour and 5 minutes after the next hour. For example, reset the clock between 9:40 AM to 10:05 AM.
How to verify a Transmitter is currently broadcasting from its front panel display
14000 Transmitter: when SB is not displayed, it's broadcasting.
XR Transmitter: green LED is solid green.
OneVue Transmitter: Transmit LED is solid green.
For Transmitter with an external antenna and it's not in an error state: power the down the Transmitter, wait 30 seconds, and power back on. A power-cycle forces the Transmitter to broadcast for eight consecutive hours. This will also be helpful if you have multiple clocks to reset.
Remove both of the clock's batteries.
On the backside of the clock, press and release the button five (5) times. This will drain any excess charge from the clock circuitry.
Stretch the battery contact tabs in the battery holder out. When the batteries are re-inserted, the tabs apply more pressure to the battery contacts.
Reinsert the batteries or if the batteries are expired insert new batteries.
Be sure to always use new, high-quality Alkaline batteries with an expiration date greater than 5 years from the current year.
When batteries are re-inserted, observe the clock.
The second hand begins advancing one second and pausing as the clock searches for the channel and frequency (signal) the Transmitter is broadcasting at.
Once the clock receives a signal from a Transmitter, it rapidly spins the second hand to the 12:00 position and stops. Next, the hour and minute hands advance toward the correct time, the hands pause for approximately five seconds at a displayed hand position of either 4, 8, or 12 o'clock (whichever of these positions falls just before the actual time). The minute and hour hand begin to advance to the proper hour, minute and the second hand is last to the proper second.
