It is recommended that AA lithium batteries are used for the low
temperature operation of sensors (freezers etc).
INSTALLING BATTERIES
For the two remote sensor units, remove the battery compartment
cover by sliding it downwards. Insert 2 "AA" alkaline/lithium
batteries. Lithium batteries function at lower temperatures better
than alkaline batteries.
PLACEMENT
The remote units should be fixed onto the refrigerator/freezer at this
stage. Each remote unit is equipped with a spring-action clip for
securing inside the refrigerator or freezer. The clip is designed with
rubber grips to securely hold the remote unit to the edge of glass or
wire shelf commonly found in modern refrigerators.
Alternatively, the included detachable suction cup may be used to
secure the remote sensor to the interior surface Ref #1. A remote
unit kept in a freezing temperature should be secured using the
integrated spring-clip Ref #2.
The main unit may be mounted directly to the refrigerator surface
utilizing the magnetic back of the unit. The main unit may also be
placed on a table or other flat surface using the integrated fold-out
stand on the back of the unit.
THE MAIN DISPLAY
Each sensor's temperature is represented on the main display in
three ways. The largest numbers displayed represent the current
temperature of each remote sensor. The two smaller numbers to
the right in each sensor's display window represent the minimum
and maximum-recorded temperatures. The recorded MIN/MAX
numbers can be cleared by pushing the "CLR" button. You may also
choose between Fahrenheit or Celsius temperature display mode
using the "C/F Select" switch on the back of the main unit.
TEMPERATURE ALARMS
The main unit is equipped with an audible temperature alarm for
each unit. Press the alarm button for the corresponding remote
sensor to turn the alarm function on or off. The ALARM icon on the
main display will appear if the alarm function is on. If the alarm icon
is not displayed, the alarm WILL NOT SOUND.
If the temperatures for each sensor fall below the minimum preset or
rise above the maximum preset for more than 15 minutes, the alarm
will sound. This is to prevent " False alarms" from sounding because
the door was opened to load or unload items from a refrigerator or
freezer. The sensors are supplied with the following defrost preset
alarm temperatures:
Sensor #1 (Refrigerator): minimum is 0ºC/33F, maximum is 4ºC/
40F.
Sensor #2 (Freezer): minimum is -30ºC/22F, maximum is -18ºC/0F.
You may customise the alarm to sound at your desired temperatures
for each unit. See page 5 for instructions on programming the alarm
preset.
