Low Battery Alert
The camera shows the battery level on each MMS picture. When the battery
level is high, a code B3 shows on the bottom left corner of the image. After
the battery level drops, the code changes to B2. When the battery level gets
very low, the code changes to B1, which means it’s time to change the
batteries. So you can decide when to change batteries.
