FAQ & Troubleshooting
Problem
Possible Solution
Main unit
reading
the letter E or
dashes
1. Bring all 3 units together, side by side.
2. Remove the batteries from all 3 units.
3. Place the batteries into the main unit first.
4. Place the batteries into sensor #1.
5. Place the batteries into sensor #2.
6. The main unit should read temperatures from both
sensors almost instantly.
Set alarm to
custom min/max
temperatures
The default feature for sensor #1 (refrigerator) is minimum
33ºF/maximum 40ºF. Sensor #2 (freezer) will default to a
minimum -22ºF/maximum 0ºF.
To set the alarms to a customized min/max temperature:
1. Press and hold the bell #1 button until the unit beeps.
Where the current temperature was, the maximum
alarm temperature will blink.
2. Use the + or – buttons to change it.
3. Press and release the bell #1 button. The minimum
alarm temperature will blink.
4. Use the + or – buttons to change it.
5. Do this same process using the bell #2 button to
customize the maximum alarm temperatures.
NOTE: When unit is in normal operating mode (not in alarm
set mode), the min/max readings to the right of each current
temperature reading are the min/max temperature
recordings.
When do
min/max
records reset?
The min/max records appear to the right of the current
temperature reading from each sensor. These readings
reflect the minimum and maximum temperatures recorded
since the batteries were inserted or since the CLR button
was last pressed. To clear the min/max records, press and
release the CLR button once. This clears the records from
both sensors.
