F. G-Switch Functional Check – Item 4
CAUTION: A JUMPER IS REQUIRED TO PERFORM THIS CHECK. DUE TO THE POTENTIAL OF
PHYSICAL DAMAGE IF THE JUMPER IS IMPROPERLY INSTALLED, THIS STEP SHOULD
ONLY BE PERFORMED BY AN EXPERIENCED TECHNICIAN/MECHANIC.
(1) Reinstall the battery in accordance with SUBTASK 25-62-13-450-001 on page 78.
NOTE: If tests 5a through 5h are going to be performed, the battery may be temporarily
installed with only two screws, located on a diagonal from each other.
(2) Perform this functional check within the first 5 minutes after the hour (UTC), as required by
AC 43.13-1, Chapter 12, § 12-22, Note 3.
(3) Notify any nearby control tower of your intentions.
(4) Install the C406-N Test Loop Back Plug (151-5060) on the ELT receptacle or a jumper
between Pins 12 and 13 of the ELT receptacle.
NOTE: The ELT cannot be activated using this procedure unless Pins 12 and 13 on the ELT
plug are jumpered. See "Figure 21. Remote Switch Harness Wiring Diagram”, on
page 69.
(5) Verify the ELT switch is in the “OFF” position.
(6) Monitor 121.5 MHz on an AM receiver.
(7) Activate the ELT by using a rapid forward (i.e., throwing) motion in the direction of the arrow
on the ELT label, followed by a rapid reversing action.
(8) Verify activation by listening for the aural sweep tone on the receiver.
(9) Reset the ELT by toggling the control switch to the “ON” position and then back to the “OFF”
position.

G. Performance Testing Setup
NOTE: The ELT software routine logs battery life in 30-second increments. A minimum of 30
seconds is added to the battery usage total each time the ELT is activated and de-activated.
If the ELT is left activated beyond the first 30 seconds, additional time is added in 30-
second increments.
NOTE: Careful planning of the performance tests is necessary to avoid activating the ELT more
than necessary. Plan the performance testing in a manner that allows tests to be run
concurrently and test equipment settings to be quickly switched from one test to another.
By doing so, the three-minute warm-up requirement can be eliminated from a number of
tests and battery run time minimized to a large extent.
