located on the aft portion of the center console. Audio to all four
headsets is controlled by the individual audio selector switches on the
audio control panel and adjusted for volume level by using the selected
receiver volume controls.
Audio Input Jack
Two audio input jacks are provided on the aft portion of the center
console. One jack is located near the convenience outlet for use by the
pilot and forward passenger, and another is located further aft by the
rear passenger ANR power jacks. These jacks can be used to plug in
personal entertainment devices such as portable radios, cassette
players, or CD players. Audio volume through these jacks is controlled
by connected individual entertainment device.
Emergency Locator Transmitter
The airplane is equipped with a self-contained emergency locator
transmitter (ELT). The transmitter and antenna are installed
immediately behind the aft cabin bulkhead to the right of the airplane
centerline. The main transmitter control switch, labeled ON-OFFARMED,
on the transmitter is in the armed position for normal
operations. A remote switch and indicator panel is installed
immediately below the circuit breaker panel. The transmitter unit is
mounted longitudinally in the airplane in order to detect deceleration
greater than 3.5 ft/sec. If rapid deceleration is detected, the transmitter
will repeatedly transmit VHF band audio sweeps at 121.5 MHz and
243.0 MHz approximately 0.5 seconds apart. The transmitter and
portable antenna are accessible through an access at the base of the
baggage compartment bulkhead. The ELT can be removed from the
airplane and used as a personal locating device if it is necessary to
leave the airplane after an accident. Eight dated “D” cell alkaline

batteries contained within the transmitter unit power the ELT
transmitter. The batteries must be replaced at specified intervals
based upon the date appearing on the battery (refer to Airplane
Maintenance Manual).
ELT Remote Switch and Indicator Panel
The ELT remote switch and indicator panel located immediately below
the circuit breaker panel, provides test and monitoring functions for the
ELT. The panel contains a button labeled ON, a button labeled RESET,
and a red LED (light). The red light flashes when the ELT is
transmitting. The ON button is used to test the unit in accordance with
the maintenance manual procedures. The RESET button can be used
to cancel an inadvertent transmission. A 6-volt Lithium battery
mounted in the panel powers the LED. The battery must be replaced
at regular intervals (refer to Airplane Maintenance Manual).
In the event of an accident:
1. Verify ELT operation by noting that the ELT indicator light on the
remote panel is flashing.
2. If possible, access the unit as described below and set the ELT
main transmitter control switch ON.
Portable use of ELT:
a. Remove access at lower aft center of baggage compartment.
b. Disconnect fixed antenna lead from front of unit.
c. Disconnect lead from remote switch and indicator unit.
d. Loosen attach straps and remove transmitter unit and portable
antenna.
e. Attach portable antenna to antenna jack on front of unit.
f. Set main control switch to ON.
g. Hold antenna upright as much as possible.
