ACK! E-04 Pre-Installation Checklist

MODEL E-04 PRE-INSTALLATION CHECKLIST
DO NOT
Place the red rubber cap on the ELT main switch unless it is in the ARMED position.
Placing the cap on when in the off position can turn the ELT on will run down the battery
and may damage the 406 MHZ amplifier.
Mount the ELT near sources of RF or EMF radiation i.e. Transponders,
ADS-B, Comm radios, HF radios, Strobe power supplies, Solenoids, Actuators, Battery
cables, or any other source of radiated energy.
Rout the remote cable along side coax or other cables that can radiate RF or EMI energy.
Mount the antenna closer than 3 feet from a comm antenna.
Mount the antenna closer than 3 feet from an ADS-B antenna
Mount the antenna next to a GPS antenna or when the GPS antenna will be between the
comm antenna and ELT antenna. It can cause GPS signal interference when transmitting
on the comm radio.
Mount the static suppressor directly to the ELT. It will damage the 406 MHz amplifier.
Mount the Remote or Audio Alert where it can be subject to water infiltration i.e. under
side windows, wing roots, where windshield leaks can occur, in the air stream of outside
air vents.
Allow the RJ 11 cable connector to rest in the bottom of the fuselage where water can
collect.
DO
Read the manual before starting installation.
Before starting the installation visit our web site www.ackavionics.com and read the
installation advisories under technical support for the E-04. Especially the Soldering of the
DIN connector.
Install batteries in the Remote and Audio Alert.
Only use an antenna that is approved for use with our ELT. Rubber Ducky type antennas
are not suitable and will damage the 406 MHz amplifier. The same goes for existing
121.5/243 MHz antennas.
Make sure the antenna has an adequate ground plane. A 14" diameter is the absolute
minimum ground plane that is acceptable. This will provide full 406 MHz power. The 121.5
MHz power will remain above the minimum EIRP power required by TSO-C91a.
