Getting started
Baby unit battery installation
You can power up the baby unit by connecting it to AC power or to four
AA alkaline batteries. Even if the baby unit is connected to AC power, we
recommend you also install four AA alkaline batteries. This guarantees
continual operation in case of a power outage.
Install four AA alkaline batteries (not supplied) into the battery compartment,
matching the polarity markings ( + and -) inside the battery compartment.
Make sure the ribbon attached inside the battery compartment is put under the
batteries and the excess ribbon is tucked in properly. Then replace the battery
compartment cover.
Do not mix old and new batteries. Do not mix alkaline and standard
(carbon-zinc) batteries.
The operating time for using AA batteries is short, only for a few hours. If you
want to monitor your baby for a long time, we recommend you connect your
baby unit to AC power.
If the baby unit will not be used for a long time, disconnect and remove the
bat tery to prevent possible leakage.
You can use rechargeable AA batteries for the baby unit, but the baby unit
cannot charge rechargeable batteries.
