Removing the lithium ion battery assembly
in
The battery pack assembly consists of the rechargeable lithium ion cells, a protection
board, and the battery door. It can be replaced only as an assembly.
1.
Remove the two screws securing the battery door.
2.
Remove the battery assembly from the battery compartment.
WARNING
The lithium ion battery can deliver currents sufficient to cause
serious personal injury and to damage the monitor. Before opening the monitor
for any reason, and before you begin any procedure described in this manual,
always remove the battery first.
WARNING
The only safe method for charging the monitor battery is to insert the
completely assembled monitor, with the completely assembled battery pack
correctly installed, into the completely assembled charging cradle. Attempting to
charge the monitor battery by any other method creates a significant risk of
explosion or patient shock hazard.
WARNING
Do not short the battery connector pins.
WARNING
Do not attempt to disassemble the battery. The battery pack
contains no user-serviceable parts.
Note
When the monitor, the cradle, or the battery reaches end of life, recycle it locally
according to national, state, and local regulations, or return it to Welch Allyn.
