If the product is powered on (with blue LED indicator light) but frozen, please wait until the LED light
indicator is off; and retry to power on.
If the display does not power on, the battery needs to be charged.
Q4: How often should I charge the battery?
A: Our door sign is designed to work for 6 months under normal use without charging. Depending on
how frequently users change the messages as that is the only time it consumes power when refreshing.
You may need to charge more often if that is the case.

A: We recommend 3M Command Strips (small size) or equivalent which is detachable on different
surfaces.
