(7)

Reset the ELT by toggling the ELT local control switch to “ON” and back to “ARM” after 1-2

seconds, if the ELT activates.

NOTE: This step may be necessary because the ELT will occasionally activate when power is

connected to it in Step 6.

(8)

Fit the battery pack into place on the ELT, making sure the gasket is positioned correctly.

(9)

Turn the battery pack bottom face up to facilitate installing the screws, while securely holding

the ELT and battery pack together.

(10) Install the eight battery pack retaining screws and tighten until the ELT is snug against the

gasket.

(11) Torque the screws to 10-12 lb-in (113-136 N•cm).

(12) Perform an ELT self-test as follows:

(a)

Set the ELT local control switch in the “ON” position. The LED will begin flashing every 3-

4 seconds.

(b)

Return the switch to the “ARM” position after 1-2 seconds. If the ELT is working

properly, the LED will stay on for approximately 1 second. The ELT may flash the

following expected error codes, which should be ignored.

3-flash and 4-flash errors, which are generated because the ELT is not installed

and connected to an antenna, etc.

A 5-flash error will be indicated if the ELT is programed with a location protocol,

and is generated because the ELT is not connected to the navigation system and

receiving position data.

A 6-flash error will indicate the G-Switch loop between pins 5 and 12 on the D-Sub

connector is open or not installed.

(c)

If a 7-flash error code is indicated, there is a problem with the battery or battery

connection wiring. Refer to Table 6 on page 42.
