Batteries
Explanation: Many problems are resolved with fresh batteries of the appropriate
voltage. Many items sent in under warranty work, when tested with fresh batteries.
Batteries manufactured this year will have an expiration date 10 years (or more) 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.
We suggest name brand Alkaline batteries for indoor displays.
A minimum voltage of 1.48V for each battery is necessary for proper
performance.
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.
Good name brand batteries make less noise, which reduces the chance of RF
(radio frequency) interference from the battery compartment.
Digital Clock Factory Restart
Explanation: The factory restart returns the clock and outdoor sensor to an “out-
of-the-box” default 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 clock is blank before proceeding (there may be lines painted on
the screen that will show when there is no power).
4.
Leave both units without power for 15 minutes (very important).
5.
Insert fresh batteries into the outdoor sensor, then into the clock.
6.
Press the TX button on the outdoor sensor to transmit RF signal.
7.
Keep the outdoor sensor 5-10 feet from the clock.
8.
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.
9.
Do not press buttons for 15 minutes.
For optimum 433MHz transmission, place the outdoor sensor no more than 300
feet (91 meters, open air) from the clock.
