4.4.3 Corrosion Inspection
Inspect all metal parts of the ELT exterior, its mounting tray, RF coax cable, remote switch and
cable, and the antenna and its hardware for signs of corrosion. This includes mounting screws,
electrical connectors, antenna base mount, etc.
4.4.4 Battery Removal
CAUTION:
The battery pack contains electrostatic sensitive parts.
Take ESD precautions before handling.
Damage may happen to the exposed electronic parts and prevent correct
operation of the ELT. Refer to paragraph 5.1 for methods of preventing
an
Electrostatic Discharge (ESD).
1) Remove the 8 securing screws from the battery-side cover. Battery pack is identified
by the embossed text: “BATTERY ACCESS ON THIS SIDE”.
2) Carefully lift the battery cover (battery pack) away from the ELT and unplug the flex-
cable connected to the pack. Do not pull on the flexible portion of the cable - use the
rigid section of the flex circuit at the connector as a handle.
3) Inspect the battery pack and ELT chassis. The battery cells, components and
connectors should be free of corrosion. Inspect flex-circuit for broken connections or
damage. Ensure the battery housing is free of cracks or other visible damage.
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.
