NOTE

You need to trigger the sensor by motion to 
activate the change of Pet Immunity setting. 
A message to this effect will appear on this 
handset display.
As the motion sensor uses thermal body heat 
to detect motion, the Pet Immunity function 
works off thermal body heat parameters to an 
approximate mass of 25kgs. If the pet gets too 
close (within 2 metres), or too far (outside of  
12 metres) from the sensor’s range, its 
movement may still trigger the sensor as the 
mass detection function may be affected by 
proximity.

General product care

Taking care of your sensor

Your sensor contains sophisticated electronic 
parts, so it must be treated with care.

Avoid rough treatment

Place the sensor down gently. Save the original 
packing materials to protect your sensor if you 
ever need to ship it.

Avoid water

Your sensor can be damaged if it gets wet. Do 
not use the sensor outdoors in the rain, or handle 
it with wet hands. Do not install the sensor near a 
sink, bathtub or shower.

Electrical storms

Electrical storms can sometimes cause power 
surges harmful to electronic equipment. For your 
own safety, take caution when using electrical 
appliances during storms.

Cleaning your sensor

Your sensor has a durable plastic casing that 
should retain its luster for many years. Clean it 
only with a dry non-abrasive cloth. Do not use 
dampened cloth or cleaning solvents of any kind.

When you are not going to use the sensor for 
some time, remove the battery from the sensor.
