Q. Alarm unit cannot detect underwater wave signal
Check the unit by hitting the “?” button. If the unit does not
give any beep, replace the 9V battery with a new one.
Check the phone jack connection between the sensor tube
and the alarm unit control head. Make sure it is connected
properly.
Check the sensitivity setting on the bottom of the underwater
sensor and the depth of the sensor into the water.
Q. The alarm unit gives frequent false alarms
Check the unit installation. Make sure it is mounted rigidly
and straight upright. If the unit can be moved sidewise under
strong wind, it indicates the unit is not mounted rigidly.
Check the sensitivity setting. The sensitivity may be set too
high.
The sensor can detect any water disturbance including the
flow from the filter pump. Place the alarm unit away from the
return, or put a deflector cap on the sensor cage.
Q. The temperature display stops working
Hit the RESET key located under the 9V battery.
If the display does not come up, replace the AA battery.
Q. The poolside alarm unit siren cannot be turned OFF
Push and hold BOTH the green button and yellow button for
3 seconds until you hear 5 consecutive beeps.
Wait until the water settles down before you turn on the unit
again.
Q. The receiver does not sound alarm immediately when the
poolside alarm goes off
The transmitter makes 3 attempts in 10 seconds. If the
receiver missed the first transmission because of interfer
ence, it has the 2
nd
and then the 3
rd
chance to pick up the RF
alarm signal. Because of this, occasionally the receiver may
experience a time delay.
Weak RF signal is more susceptible to any interference.
Replace the 9V battery with a new one.
