2.3 Parent Unit Power Supply
1.
NOTE
A rechargeable battery (Lithium ion battery 2000mAh) inside the
Parent Unit allows you to move it without losing the link and
picture from the Baby Unit. The battery gives up to 5 hours
operation for the Parent Unit. We recommend you charge it for at
least 16 hours before first use, or when the Parent Unit indicates
the battery is low.
