A.
The installer and aircraft owner must read the Warranty before starting the installation.
There is information in the Warranty that may alter your decision to install this device.
If you do
not accept the terms of the Warranty, do not install this device.

. If you are not an FAA Certified Aircraft Mechanic familiar with the issues of installing
aircraft instruments, Do Not attempt to install this device. The installer should use cur-
rent aircraft standards and practices to install this unit (refer to AC 43.13-2A).
C. This device's installation may be considered a minor alteration (as is true for clocks, radios, inter-
coms, headsets, audio panels, encoders, etc.). Installation of this device can be accomplished
utilizing FAA acceptable methods, techniques and practices covered under AC 43.13-2A. This is a
requirement under FAR Part 1 to qualify as a minor alteration. This instrument does not "apprecia-
bly" affect weight and balance or electrical load as described in FAR Part 1 and FAR 43 Appendix
A (another requirement to qualify as a minor alteration). The MUX-8A meets the environmental
requirements of DO-160C. The MUX-8 is manufactured in Electronics International's FAA PMA/
TSO approved manufacturing facility. If the installer determines that installing this device is a minor
alteration, he/she must note it as such in the aircraft log book. Example:
"2/6/00 Installed Elec-
tronics International's MUX-8A as a minor alteration. This device was installed in accor-
dance with Installation Instructions II 1221991 dated 12/21/99 and AC 43.13-2A."
A minor
alteration does not require a 337.
Resolve any possible FAA approval issues prior to starting
the installation.
D.

before starting the installation. This may eliminate any delays once the installation is
started.

4" clearance behind the aircraft instrument panel.
Drill a 1/4" hole in the aircraft instrument panel for the MUX-8A Control Switch and faceplate. Mount
the Switch from behind the aircraft instrument panel. The Switch should be mounted with the yellow wire
"Down." The down position should be momentary.
