If the low battery warning keeps reappearing on your Visonic Powermax PIR motion sensor, it is likely that the battery needs to be replaced. Here are the steps you can follow to replace the battery:

1. Remove the battery cover on the back of the sensor by pressing the tab and pulling the cover off.
2. Remove the old battery and dispose of it properly.
3. Insert a fresh CR123A lithium battery into the battery compartment. Make sure to insert the battery with the positive (+) end facing outward.
4. Reattach the battery cover to the sensor.
5. Test the sensor to ensure that it is functioning properly.

If the low battery warning continues to appear even after you have replaced the battery, there may be a problem with the sensor itself. In this case, it is best to contact the manufacturer or a qualified technician for assistance.

not unless you get a new motion sensor
better to use your foot or junk it

It may have been previously learned into a zone. Sometimes, the motion will trip and activate a signal that can be learned into another zone you are trying to program. exit programming, then "tamper" the cover for the circuit board, not the battery access, on the motion, check the "status" light to see if a zone is displaying "tamper". Also check battery orientation in back of motion. When battery is first installed correctly. The light should activate during the first minute.

The backup battery that help the system keypad/receiver unit to operate it is low in power and it is dying and in need of a new battery replacement.Traced the system back where main junktion and overide to the system box unit is should have the battery there.This battery really easy to do a replacement.The battery it is like a similar to a motor cycle battery.

there is a slide switch on the bottom of the sensor......test....1 min.....5min...
u may have to reset the sensor....turn power off .....then remove batteries.....wait 5 min....then turn on power....then replace batteries ......do not move the sensor and wait 1.5 minutes...
U can also call heath zenith @ 800 858-8501 and talk to tech support....

Hello,
Do you mean the screen is blank or you cannot remember how to program it? Was it working perfect until you replaced the Battery?
Make sure the battery is inserted with the positivet side up?
Manual is here: http://www.sportline.com/manuals/370.pdf
Replacing the battery: 1. Unscrew the battery compartment cover on the backside of the unit using a small Phillips screwdriver and remove the cover. 2. Remove the exhausted battery from the unit, and insert a new battery (be sure to place the positive (+) side of the battery is visible, facing toward the battery compartment cover). 3. Replace the battery compartment cover on the battery compartment and fasten the screw (CAUTION: do not over tighten).
