ELT Battery replacement:
1) If replacing the battery pack, order replacement kit 455-0012 which contains the battery pack
(452-6499), replacement gasket, hardware and labels. A spare label showing the expiration
date is included in the replacement kit. This label should be mounted in the same location as
the former expiration date label.
2) Lay the battery pack on the work surface with the batteries facing up. Install a replacement
seal in the slot along the perimeter of the housing. Leaving the battery as it is, position the
ELT over the battery pack with one hand and plug the flex-cable connector into the battery
assembly using the other. The cable should not be twisted and the connector should 'click'
into place.
Note: The battery connector is keyed to prevent incorrect installation.
