2. A continuous “siren” sound.
SENSOR REPLACEMENT
In either case, replacement of the sensor is necessary:
1. Turn the power off.
2. Locate the replacement sensor in the battery compartment.
3. Unscrew (turn counter clockwise) the old sensor from the end of the probe.
4. Screw (turn clockwise) the new sensor into place.
