7) To cease operation of the ELT, remove the unit from the plastic bag and dry
off the bottom cover with cloth or paper.
* NOTE: Any waterbased liquid may be used to fill the bag, such as coffee or any
beverage, denatured alcohol, urine, etc. Oil based liquids such as hydraulic fluids
are generally not suitable since they do not conduct electricity.
a) To assure optimum performance of the ELT, the lower third of the unit should
be kept submerged. Using less water will reduce battery performance.
b) The ELT should be located in a clear area away from trees, boulders, or other
large objects. The ELT may be carried when operating, however the unit
should be held high enough so that the entire length of the flexible antenna is
above the carrier's head and clear of any other obstructions.

TESTING
5.1
General
1) CAUTION: FCC regulations require that ELT testing be performed in an RF
shielded room. Testing outside of a shielded room may only be performed
during the first five minutes of each hour, and then only for a maximum
duration of three audio sweeps (equivalent to one flash of the red indicator
light).
2) The ELT possesses a self-test feature, which monitors the signal at the antenna
terminal. The red indicator light will flash only if the proper signal is detected.
3) An ELT should always be self-tested prior to the initial installation (see
section 5.2). Periodic testing is recommended to help assure that the ELT will
function optimally and reliably in an emergency.
4) An ELT should always be shop tested prior to reinstallation (see section 5.3).
5.2
Operational Test - Self Test
Test Equipment Required:
1) 12 volts power supply.
2) RF screen room or test within the first 5 minutes of each hour (see section 5.1,
note 1)
