Testing the units
After installing the batteries in the remote sensor and before
replacing the back cover, try the following test to make sure
the two units are communicating.
1. Place the two units approximately five feet apart and
press and hold for 2 seconds the TX button inside the
battery compartment on the remote sensor. The receiving
unit should now display the temperature reading for that
sensor.
2. Next, place the sensor in the desired remote location and
place the receiving unit it its desired location.
3. Press and hold the TX button again.
4. Check the receiving unit display for that sensor. If the
dash icon (—) appears and flashes, it indicates a signal
interruption. RF signal interruptions can be caused by
interference from electronic devices or physical
obstructions such as walls, buildings etc...
5. Rotate the sensor in 45° steps and press the TX button
again to send the signal.
6. If there is still no display, move the remote sensor closer
to the receiving unit or reposition both the receiving unit
and the remote sensor until reception is observed.
7. When complete, put the rubber seal into the cover groove
and close the battery cover. Tighten the screws, and snap
on the bracket stand.

temperature alert function press the ALERT button once.
7. When the temperature goes above or below the pre-defined
range, the corresponding segment will start to blink and the
buzzer will beep for 5 seconds followed by 45 seconds off. This
