Procedure to Trouble Shoot Battery Operation:
To help ascertain what is going on, can you please try the below:
There is a green light on the front of the monitor when it is turned on.
Sometimes when the battery has failed it will affect the operation of the monitor even when plugged into a wall outlet.
Open the back and disconnect (or remove) the battery, plug the monitor into a wall outlet and confirm that the monitor is working properly.
• The monitor does not need to have the battery installed in order to work when plugged into the wall via the power cord.
• If it works fine then it is most likely they just need a new battery.
Note: There are some electronics associated with the battery charging circuit that can fail and cause the device to not charge properly. This is not that common. Most battery problems are due to failed batteries.
