SYSTEM FUNCTIONAL DESCRIPTION AND OPERATION
1. Transmitter
The KANNAD 406 AS is designed to transmit on three frequencies (121.5, 243
and 406 MHz).The two basic aeronautical emergency frequencies (121.5 and
243 MHz) are mainly used for homing in the final stages of the rescue
operations. The 406 MHz frequency is used by the COSPAS-SARSAT
satellites for precise pinpointing and identification of the aircraft in distress.
Once activated, the transmitter operates continuously on 121.5 and 243 MHz.
The output power is 100 mW on each frequency.
The modulation is an audio frequency sweeping downwards from 1420 Hz to
490 Hz with a repetition rate of 3 Hz.
During the 24 first hours of operation, a signal is transmitted on 406 MHz every
50 seconds to the COSPAS-SARSAT satellites. The output power on 406 MHz
is near 5W.
2. Controls
The following controls are to be found on the ELT front panel (from left to right):
1. 3-position switch ARM/OFF/ON;
2. Visual indicator (red);
3. DIN 12 connector for dongle, water switch sensor, or programming
equipment connection;
4. BNC or TNC connector for the antenna.

by a locking latch. To operate the switches, the lever shall be pulled to
unlock then set to position.
