Print PageERROR CODE
MEANING
2 code.
Missing G-switch loop back:
Can indicate that the ELT is not fully seated in its
mount, or the mating connector is not properly
attached. It can also indicate a missing jumper
from pin 1 to pin 11. This condition renders the G-
switch inoperative.
3 code.
Bad 121.500 MHz RF output power:
Can mean that the homer signal on 121.5 MHz is
not operating. This error code is normal with the
tape blade antenna.
See Section 6 for test recommendations.
4 code.
Bad 406 MHz RF VSWR:
Can indicate an antenna close to other objects.
5 code.
Low 406 RF power output:
Can indicate a low voltage battery, or a defective
406 power amplifier.
6 code.
Bad EEPROM data:
Can indicate a hardware or software fault. ELT will
only transmit on 121.5 & 243 MHz.
7 code.
Bad RAM:
Can indicate a hardware or software fault. ELT will
only transmit on 121.5 & 243 MHz.
SECTION 8
OPERATING INSTRUCTIONS
The EBC-406HM is for aviation emergency use only. In an accident
with sufficient G-forces, the ELT is automatically activated.
When using in an emergency, remove ELT from its mount, exit
the aircraft, and set the toggle switch to the "ON" position.
Setting the ELT's toggle switch to the "ON" position manually activates
the ELT.
When the ELT is automatically or manually activated, there is a 1-
second delay before the 121.500 MHz / 243.00 MHz homer transmitter
activates. This is followed approximately 50 seconds later by the
406.028 MHz burst.
REMOVING THE ELT FROM THE BB-12M MOUNTING BRACKET
Remove the ELT from its mounting bracket by simultaneously using
the thumb to push on the snap lock, and the forefinger to pull up on
the latch lever. Move the latch out of the way, and pull the ELT out by
the lanyard.
REMOVING THE ELT FROM THE BB-15M MOUNTING TRAY
Remove the ELT from its mounting tray by simultaneously using the
thumb to push on the snap lock, and the forefinger to pull up on the
latch lever. Compress the strap against the ELT so that the latch clears
the keeper. Move the straps out of the way, and pull out the ELT.
Place the ELT on high ground with the antenna in a vertical
position. For longest operating life, if using at temperatures
below –20 C, keep the transmitter inside your jacket with the
antenna exposed.

NOTE: The FCC has mandated that the transmitter test be performed
only during the first 5 minutes of each hour and last no longer than 3
audio sweeps of the ELT signal. The test must be performed a
minimum of once a year.
1. Remove the ELT Tape antenna. Visually inspect and confirm proper
seating of all BNC connector pins at the antenna end, and at the ELT
end. Special attention should be given to coaxial center conductor pin,
which may retract into the conductor housing. Check for corrosion, and
any obvious signs of wear.
2. Remove the ELT from its mount and inspect D-Sub connectors for
corrosion, and any obvious signs of damage, such as bent or missing
pins. Inspect the mounting hardware for stability. All required mounting
hardware should be reinstalled and secured.
3. Inspect the battery pack. No corrosion should be detectable. Verify
that the ELT battery connectors are fully mated with no gap between
them. Verify that the battery is an approved pack, GS-46,
manufactured by Emergency Beacon Corporation. Check the battery
pack's expiration date.
4. Perform full functional tests as described in Section 6.
SECTION 10
EQUIPMENT LIMITATIONS
The conditions and tests required for TSO approval of this article are
minimum performance standards. It is the responsibility of those
desiring to install this article on a specific type or class of aircraft to
determine that the aircraft installation conditions are within the TSO
standards. The article may be installed only if further evaluation by the
applicant documents an acceptable installation and it is approved by
the Administrator.
This equipment must be installed according to the recommendations
outlined in this manual. Only Emergency Beacon Corporation TSO
approved parts are to be used. Substitution of other components will
void the warranty. Any deviation may result in failure of the equipment
to operate properly.
SECTION 11
BATTERY REPLACEMENT
FAR 91.207(c) requires that the battery in the ELT be replaced in
accordance with the replacement date marked on the ELT or when
the transmitter has been in use for more than one cumulative hour.
The battery replace label is found on the exterior of the ELT and on
the battery. The battery pack must be replaced every 5 years or after
one hour of cumulative use. The battery should not be stored where
the ambient temperature is above 80C, or below –40C.
WARNING: Use only battery, P/N GS-46. The ELT will not meet the
requirements of TSO-C126 if used with another battery. GS-46 battery
packs are available from Emergency Beacon Corporation (EBC) and
its dealers.
BATTERY INSTALLATION PROCEDURE:
1. Verify that the ELT is off, and remove it from its mount.
2. Unscrew the 4 back cover screws and remove cover.
