Avoid engine starts below -15°C (5°F) without

preheat.

2. Preheat the battery, engine, oil tank, and main rotor
gearbox with an appropriate heater system for at least 30

minutes; or overnight in extreme cold, -25°C (-13°F) and below.

CHAPTER 5. OPTIONAL EQUIPMENT SUPPLEMENTS

5-1. General

1. Refer to the basic RFM.

2. In addition to the applicable equipment installations set
forth in the basic RFM, the instructions for the following
installed equipment must be observed.

5-2. Emergency Locator Transmitter

1. The 480/480B is equipped with a fixed ELT, model AK-

451.

2. The ELT should be registered with the local National
Authority. The 406 MHz ELT transmits a programmed UIN
when activated. Registration provides SAR organizations with
contact information to verify an actual emergency, assist
identification, and speed the launch of a rescue operation.

WARNING

The AK-451 ELT should be registered with
the National Authority prior to use. Lack of
registration could delay rescue operation in
an actual emergency.

3. The AK-451 ELT transmits on the following frequencies:

121.5 MHz, 243.0 MHz, and 406 MHz.

4. Main switch selection “ARM”:

a. For normal operation, set the main switch at “ARM”

position. A self-test is confirmed after 24 seconds. The
two green ON lights and the buzzer sound will extinguish
after a successful self-test.

b. The AK-451 ELT will automatically activate upon impact.

5. Main switch selection “ON”:

a. Set the main switch to “ON” to transmit immediately.

Both green ON lights will flash and the buzzer will
sound.

6. In the event of a crash, the AK-451 ELT activates
automatically, and transmits the standard swept tone on
243/121.5 MHz lasting until battery power is gone.

a. For the first 24 hours of operation, a 406 MHz signal is

transmitted at 50 second intervals. This transmission
contains identification data programmed into the ELT to
be received by COSPAS-SARSAT satellites.

b. If it is necessary to leave the scene of the accident, the

AK-451 may be removed from the aircraft and used as a
personal locating device.

7. Main switch selection “OFF”:

a. Set the main switch to “OFF” when handling or shipping

the beacon to avoid nuisance activation.

8. In case of an inadvertent activation, contact the local
National Authority to report false alarms. Any activation of a
406 MHz for a few seconds will usually be detected, and if no
actual emergency exists, will generate a false alarm.
