4) Verify the battery expiration date. If the battery pack has not expired it may be reinstalled.
The battery pack must be replaced with a new one:
• After use in an emergency.
• When the transmitter has been in use for more than 1 cumulative hour; (7 flash error)
• After an inadvertent activation of unknown duration.
• On or before the battery replacement (expiration) date.
• There is any evidence of corrosion or leakage of any cell or on the small interface board
and connector.
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.
