Charging A Spare Rechargeable Battery
A rechargeable Li-ion battery can be charged when it is
not inside the monitor. The charging cradle is designed
to accommodate both types of charging. Contacts on the
bottom of the battery meet the contacts on the cradle,
transferring power without other connections, and a
spring-loaded capture holds the battery in place during
charging.
1. Plug the AC/DC adapter into the monitor’s
cradle.
2. Place the battery into the cradle, with the gold-
plated contacts on top of the six matching
charging pins.
3. Plug the AC/DC adapter into the wall outlet.
The battery begins charging automatically. During
charging, the Secondary LED in the cradle blinks green.
When charging is complete, it glows steady green.
