Get Started (rechargeable batteries)
Step 1: Insert the 1 "AA" Rechargeable Alkaline batteries
(included) into the clock. Observe the correct polarity.
Note: This clock requires 1 battery. There is a “filler battery
shell” in the place. Please leave this filler in place.
Step 3: Next, slide the battery switch to the SOLAR position
(Right).
Step 4: The clock will search for the WWVB time signal for up
to 10 minutes. Do not set the time until after the
WWVB search.
Restart: If the indoor temperature is not displayed after 30
seconds, remove battery from the clock and move battery
switch to the LEFT position. Press any button on the clock 20
times. After 15 minutes, return to Step 1 above.
IMPORTANT: If the solar panel is facing a permanent
strong light source (e.g. on top of a refrigerator with
halogen lamp), please switch the clock to alkaline battery
mode to avoid over-charging the re-chargeable alkaline
battery.
