Sensitivity
Connect jumper C. Note: When the detector
battery is almost empty, the LED flashes
continuously for calibration mode. In this
case, replace the battery.
1. Turn the potentiometer anti-clockwise to
the stop. The detector is now at the
lowest sensitivity level.
2. Tap the sensor with your hand. Tap it at
the strength where the sensor should
trigger an alarm.
The calibration mode LED flashes:
Once for a small vibration
Twice for a vibration that triggers an
alarm
Three times for a strong vibration
3. Adjust the potentiometer until the LED
flashes twice at every vibration in the
desired sensitivity range.
4. Remove jumper A if the sensor does not
register all vibrations in the desired
sensitivity range.
5. Remove jumper C when the sensor has
been set to the desired sensitivity. This
puts the detector into normal operating
mode.
