concentrations.
If there are any warnings or fault indicators that suggest there is a problem with the lithium ion battery pack
(ie. not charging when expected), it should be removed and replaced. Relocate the CX Sensor Station to a
non-hazardous area and remove power from the CX Sensor Station by turning the power switch to OFF.

new pack and reverse the directions given above, making sure the wire connections are made correctly.
