Standard Order (TSO) C-91a and FCC Rules Part 87.
1.2 Purpose
The ELT (S) is intended to be carried aboard aircraft and used to locate survivors in the
event of a ditching; it can be used, however, in over-land emergencies. When activated, it
transmits a distinctive sound on the international distress frequencies of 121.5 and 243
MHz. These signals can be used by Search and Rescue personnel to assist them in
locating survivors.

transmits a distinctive sound on the international distress frequencies of 121.5 and 243
MHz. These signals can be used by Search and Rescue personnel to assist them in
locating survivors.
Unlike other types of ELTs, the ELT (S) is intended to be removed from the aircraft and
to travel with survivors. The ELT-201 may be installed within life rafts or slide rafts or
mounted in the aircraft cabin or flightdeck.

The ELT-201 is activated by placing the unit in water. The unit is completely waterproof
and floats upright when deployed. A tether is provided for securing the unit to a life raft
or person.

The ELT-201 is also designed to be SARSAT compatible. SARSAT is an international
system of low orbiting satellites used to detect alerts from ELTs and EPIRBs and to
determine their location.

2.0 INSTALLATION
Inspect the water soluble tape (A2-05-0081) holding the antenna to the body of the unit to
make sure the antenna is held securely. Replace the water soluble tape if necessary.

Raft Pack Installation
To pack the ELT with a life raft, bend the flexible antenna downward so that it lays flat
against the body of the unit (see Figure 1). The unit is then ready to be packed.

2.2
Mounting Bracket Installation
The ELT-201 may be installed into existing ELT brackets or into an optional ACR
mounting bracket (ACR Part No. A3-06-1698). (To install the ELT into the mounting
bracket, bend the antenna downward so that it lays flat against the body of the unit (see
Figure 2). While holding the antenna in this position and the unit upright, insert the unit
into the mounting bracket clamp (see Figure 2). Secure the ELT to the mounting bracket
by pressing down on the clamp latch.
