Until a time has been set, the clock will count up the time since battery installation.
MAXIMUM/MINIMUM TEMPERATURE MEMORY RECALL
The thermometer will store the last recorded high and low temperatures over a 24-hour period.
The 24-hour period starts when the stations are powered up.
● Press the “MEM” button on the back of the base station once to display the maximum
indoor and outdoor temperature readings since the station was last reset. “MAX” will
show on the LCD.
● Press the “MEM” button a second time to display the minimum indoor and outdoor
temperature readings since the station was last reset. “MIN” will show on the LCD.
● Press the “MEM” button a third time to see current indoor and outdoor temperatures, or
the display will automatically return to current readings after 5 seconds.
To clear the maximum and minimum readings: press and hold the “MEM” button for 3 seconds
to clear both memories. The temperature displays show dashes (“--”) and the station will begin
to track new MAX and MIN readings. The memories will also reset when the station’s batteries
are removed.
PROBLEM SOLVING
1. If the base station does not receive a transmission from the remote sensor for one hour,
the outdoor temperature display will show dashes (“- -”). Press and hold the “ ” button
on the front of the base station for 3 seconds to force a transmission signal. If the
connection still fails:
a. Check that the remote is properly positioned, within the appropriate transmission
range (200 feet). Transmissions are vastly affected by building materials and
where the receiver and remote stations are positioned. Try various setups for the
best results. Shorten the distance between receiver and remote stations when
necessary.
b. Check to make sure the transmission path is clear of obstacles and interference.
c. Place the remote sensor closer to the base station.
d. Remove and reinstall all batteries. Try fresh batteries.
2. If the temperature is higher than the range of the station, the display will show “HH.H”.
If the temperature is lower, this display will show “LL.L”.
a. Indoor temperature range is 32°F to 122°F (0°C to 50°C).
b. Outdoor temperature range transmitted by remote sensor is -4°F to 140°F (-
20°C to 60°C) using alkaline batteries. (Use of Lithium batteries can extend the
range to -40°F to 140°F / -40°C to 60°C.)
3. The temperature sensors are manufactured to be accurate within plus or minus 2°F (1°C)
within a temperature range from 32 to 104°F (0 to 40°C) and plus or minus 4°F (2°C)
