5) Lay the battery pack on the work surface with the cells facing up.
6) Install the replacement seal in the slot along the perimeter of the housing.
7) Align the ELT with the new battery pack, holding it slightly above the pack with one
hand, and then 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. The
battery connector is keyed to prevent incorrect installation.
8) Mate the ELT to the battery, making sure that the seal is positioned correctly during
the process.
9) Replace the 8 securing screws and torque to 10 – 12 inch-lbs (113 -136 Newton-cm).
10) Enter pertinent battery replacement information in the aircraft log book and fill out
any other documentation required by local authority.
11) Install the duplicate copy of the expiration date label to a smooth clean surface that
allows the label to be viewed while the ELT is installed.
