1) Check the flexible antenna for creases, cracks or holes in the vinyl, and any other
damage.
2) Bend the antenna downward so that it lays flat against the body of the ELT. Release
the antenna. The antenna should return to its normal upright position with no
assistance.
3) Check the top cap for cracks, dents, or other damage. Ensure that the lower rim of the
top cap rests squarely on the body of the unit over its entire circumference
4) Check the body of the unit for cracks or other damage.
5) Check the bottom cap for cracks, dents or other damage. Ensure that it is squarely in
contact with the body of the unit over its entire circumference. Check the bottom
contacts for corrosion or other damage.
If any physical damage is observed, have the unit inspected at an ACR authorized service
center.

Battery Replacement
The ELT battery assembly should be replaced before the battery expiration date has
passed. The battery expiration date is clearly marked on the ELT label near the bottom of
the unit. This date is five years after the manufacture date, which is also marked.
The ELT battery assembly must also be replaced after the unit has been used in an
emergency or otherwise operated for an extended period of time.
Battery replacement may only be preformed at ACR Electronics, Inc. or Authorized
Battery Replacement Center (BRC) call toll free +1(800) 432-0227 for list of BRC.
The following instructions are for Battery Replacement Centers ONLY.
unauthorized service will void the warranty.
To replace the ELT battery, obtain a replacement battery assembly, ACR P/N A3-06-
2165, and a 1/8" hex key wrench. Proceed as follows (refer to Figure 1):
1) Remove reflective tape, then remove the three set screws near the top of the body of
the ELT using the hex key wrench. Retain these screws for later use.
2) Grip the top cap (i.e. transmitter module) firmly using a cloth for increased friction.
Grip the body (i.e., battery module) of the ELT firmly with the other hand.
3) Twist the top cap back and forth while pulling apart the top cap and body. Continue
until the first o-ring around the top cap is exposed.
4) After the first o-ring has been exposed, carefully pull the top cap and body apart.
5) Remove the foam cushion surrounding the connector side of the circuit board by
pulling it down away from the top cap.
6) Disengage the connectors on the bottom of the electronics assembly attached to the
top cap, thus separating the transmitter module from the case assembly.
7) Remove foam cushions and remove battery by pulling on the lanyard. The used
battery should be disposed of properly
