NOTES
If
No signal
or
Weak signal
message is displayed in sensor
setup mode, or if you do not
receive an alert when you open
the door, move the base closer to
the mounting location or move the
sensor closer to the base.
Use adhesive tape to hold the
sensor temporarily in place.

Use your parent unit to enter
the
Sensor settings
menu, and
then select the
Check signal
menu. Follow the steps to test
the sensor’s signal strength, and
then exit the sensor setup mode.
Make sure there is a good signal
received when there is motion.
Refer to
Sensor notifications
section in the User’s manual for
the alerts.
If your package includes
a Motion Sensor, please

Power
The Motion Sensor detects motion
with one-minute cool off time.
Once motion is detected, the
sensor will only start to detect
motion again after one minute.
The Motion Sensor is more
sensitive in detecting motions
crossing the space in front of the
sensor than that moving towards
the sensor.
The Motion Sensor can detect
motion occurring at distances up
to
40 feet (12 meters)
when it is
mounted at a height of
7.9 feet
(2.4 meters)
.
It is recommended to mount the
sensor at the height between
6.2 feet (1.9 meters)
and
7.5 feet
(2.3 meters)
for optimal detection
coverage.
For motion detection of babies
or pets:
If you use the Motion Sensor only
to detect the motion of babies or
pets, you can mount the sensor
at a lower position to shorten
the minimum distance before
reaching the detection area. It is
recommended to mount it at the
height
3.3 feet (1 meter)
for optimal
detection of babies or pets.
