User Proper 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.
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)
Clock: Use Alkaline batteries. Overpowered or underpowered batteries may cause loss of
indoor readings, missing segments, dim display etc.
Below Proper Clock Factory Restart
Remove all batteries from outdoor sensor and clock.
Press one of the buttons on the clock at least 20 times to clear all memory.
Verify that the clock is blank before proceeding (there may be lines painted on the screen).
Leave both units without power for 15 minutes (very important).
Insert fresh batteries into the outdoor sensor.
Insert fresh batteries into the clock.
Keep the outdoor sensor 5-10 feet from the clock.
When RF connection is established, the temperature will appear on the station. Allow the
outdoor sensor and clock to sit together for 15 minutes to establish a strong connection.
Do not press buttons for 15 minutes.
For optimum 915MHz transmission, the outdoor transmitter should be a distance of no more
than 200 feet (60 meters, open air) from the clock
