Batteries
Half of all warranty issues can be resolved with fresh batteries of the appropriate voltage.
We suggest name brand alkaline batteries for indoor displays such as Digital Atomic Clocks.
Use batteries dated at least six years in advance of the current year. Batteries dated earlier
than six years from now may still work, but may be unstable in performance.
Alkaline batteries manufactured this year will have an expiration date 10 years in the future.
Battery technology has improved and batteries will maintain voltage longer in storage.
However, the environment the batteries reside in for the 10 years can deplete the power.
Good name brand batteries make less noise, which reduces the chance of RF (radio
frequency) interference from the battery compartment. A minimum voltage of 1.48V for
each battery is necessary for proper performance.
Outdoor Transmitters
: Use Alkaline batteries (or Lithium for temperatures below - 20°F/-
28.8°C)
Indoor Displays
: Use Alkaline batteries. Overpowered or underpowered batteries may
cause loss of indoor readings, missing segments, dim display etc.
Digital Atomic Clock Factory Restart
Explanation:
The factory restart returns the wireless thermometer and outdoor sensor to an
“out-of-the-box” state and often resolves an issue.
Factory Restart:
1. Remove all power from outdoor sensor and clock.
2. Press one of the buttons on the clock at least 20 times to clear all memory.
3. Verify that the wireless thermometer is blank before proceeding (some lines are painted on
and will not disappear).
4.
Leave batteries out of both units for 15 minutes
(very important).
5. Insert fresh Alkaline batteries into the wireless thermometer.
6. Insert fresh batteries into the outdoor sensor.
7. Press the TX button on the outdoor sensor to transmit RF signal.
8. Keep the outdoor sensor 5-10 feet from the wireless thermometer.
