AREA MICROPHONE
RECORDER UNIT
The recorder unit is housed inside a crash survivable container. Access to the container is through the aft equipment bay.
The unit records data in a solid state non-volatile memory and stores 120 minutes of recorded information. An underwater locator device (ULD) is installed on the front of the recorder. The ULD emits a pulsed acoustic signal into the water after ditching of the aircraft. The ULD sonar beacon is capable of transmitting for up to 30 days after activation.
UNDERWATER ACOUSTIC BEACON
As a further detection aid, the recorder has an underwater locator beacon. the beacon is mounted on the crash survivable memory unit front bracket to facilitate reading of the batter replacement date as well as for quick removal and replacement of the beacon. The unit is equipped with a battery having a life expectancy of 6 years.

06-01-15 EMERGENCY LOCATOR TRANSMITTER
DESCRIPTION
The emergency locator transmitter (ELT) is a self contained battery operated unit, located in the top left side of the aft fu-selage. When the aircraft is subjected to excessive longitudinal forces, the ELT is automatically activated and transmits on
121.5 (VHF), 243.0 MHz (UHF) and 406.025 MHz. When the ELT is transmitting, an ELT ON (C) CAS message is illuminated.
The flight deck ELT switch is normally set to ARM. The ON position is for system test, or to manually activate the ELT. The RESET position resets the ELT.
An ELT buzzer is installed in the rear fuselage section near a venting cutout. It is installed so that the buzzer alarm will not distract the flight crew, but will be audible during ground operations and servicing when the engines are not operating.
CABIN COMMUNICATION SYSTEM (OPTIONAL)
DESCRIPTION
The cabin communication system option provides a private automatic branch exchange switching network. This network routes voice and data communications for up to nine optional active devices (handsets/FAXs/modems/data link, etc.) in the airplane and provides two air-to-ground channels. The systems includes connections of basic telephone/telecomputing equipment to UHF antenna and SATCOM links. If a data link device is installed on the airplane, the cabin communication system has the capability to communicate with the data link device using an internal modem.
COMPONENTS AND OPERATION
The digital radio components consist of: one UHF antenna, a duplexer and one airborne radio telecommunication unit.The digital handset is located in the flight compartment and has a backlit LCD display and telephone style keypad to dial calls and select various options. A credit card reader (for optional billing) is built into the handset and a two-button increase/ decrease volume control (side of handset) is also installed.
