The ELT system transmits on 3 frequencies, 121.5 MHz (Civil) and 243 MHz (Military) homing-signals and 406 MHz to the COSPAS-SARSAT satellite system. The battery-pack, installed in the ELT housing, supplies the power to operate the system.
The satellite system transmits the 406 MHz distress signal to a Local User Terminal (LUT), when the LUT is in range. The LUT receiving range is a radius of approximately 2500 km (1367 NM). When the LUT is not in receiving range, the satellite system stores the distress signal until transmission is possible. The LUT automatically processes the distress signal to identify and show the position of the aircraft to a radius of approximately 1.8 km (5900 ft.). The processed data is transmitted to a Mission Control Center (MCC). The MCC sends the data to an applicable Rescue Coordination Center (RCC), where Search And Rescue (SAR) operations are started. The 121.5 MHz and 243 MHz signals are used to find the aircraft in the final stage of SAR operation.

(3) ELT (110MX)
The ELT operates automatically or manually. The battery-pack supplies the power to operate the ELT, and has these properties:
The ELT operation includes these components:
The 406 card generates the 406.025 MHz phase modulated signal from the ASIC. The signal is a 440 msec pulse that occurs every fifty seconds, with a coded message incorporated by phase modulation. The signal goes through an amplification circuit and then to the ACU card. The card contains an EEPROM which stores the data to be used in the transmitted message, if there is no AIM installed. The EEPROM supplies the message to the ASIC before it is sent to the ACU.
The 121.5/243.0 card receives a signal from the ASIC on the 406 card. It then generates the 121.5 MHz and the 243.0 MHz amplitude modulated swept-frequency signals, and sends them to the ACU card.
The ACU card puts together the three RF output signals into one composite RF signal. The signal is sent to the antenna via the coaxial cable. The ACU card aligns the impedance of each RF output signal to the input impedance of the antenna and coaxial cable.
The interface card supplies internal and external interfaces in the ELT. The external interface is between the AIM and the ELT, the RCP and the ELT and the aircraft and the ELT. These interfaces transmit control and data signals between the components. The internal interface:
The power card controls the battery-pack power to 8.5 V, before this power is directly supplied to the 406 card and the interface card. Then the power card controls the power to 5 V and supplies the interface card. The two G-switches and the related circuitry for selection of one of the G-switches are located on the power card.

- Supplies the control and data lines to the EEPROM.
- Supplies the +5 V power to the 406 card.
- Has an interface with the power card, which supplies the power necessary to operate the other cards.
The power card controls the battery-pack power to 8.5 V, before this power is directly supplied to the 406 card and the interface card.
