Warning
Explosion Hazard. Do not remove or replace the Lithium Ion Battery Pack unless
power has been disconnected or the area is known to be free of ignitable
concentrations of flammable gases or vapors.
Removal or replacement of the
Lithium Ion Battery Pack should only be done in a non-hazardous location.
1. 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
CXT Controller to a non-hazardous area and remove power from the CXT Controller by turning
the power switch to OFF. Open the hinged door to gain access to interior. Locate the four screws
that attach the metal bracket that secures the battery pack. Undo the four screws and set them aside
carefully.
Lift metal bracket and expose battery pack. Disconnect the two wire male/female
connector to free the pack. Replace the old pack with a new pack and reverse the directions given
above, making sure the wire connections are made correctly.
2. There is a small 3.0 VDC; 0.2 Amp-hr lithium ion coin cell located and soldered onto the Main
PCB that powers the clock. There is no expectation that the coin battery will ever need to be
replaced during the 12 year service lifetime of the product. If it is concluded that it does need
exchange, the unit must be returned to the Detcon Factory for replacement of the coin cell.

If the unit requires cleaning, take a clean water-damped wet cloth and wipe off the exterior surfaces of the
