2.11 Post Installation Checkout
After wiring is complete, verify power is ONLY on pins 8, and 9 of the J2 and airframe ground on con-
nector pins 10, and 11. Failure to do so will cause serious internal damage and void PS Engineering's
warranty.
2.12 Unit Installation
To install the PAC15EX, gently slide the unit into the mounting rack until the hold-down screw is en-
gaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-head in the center of
the unit until it is secure. DO NOT OVER TIGHTEN.
CAUTION
Apply steady pressure to the front while screwing the unit into the tray to ensure even seating of the unit
and connectors.
WARNING
Do not over-tighten the lock down screw while installing the unit in tray.
Internal damage will result.
2.13 Operational Checkout
NOTE
The
IntelliVox
® is designed for ambient noise levels of 80 dB or above. Therefore some clipping may oc-
cur in a quiet cabin, such as without the engine running, in a hangar. This is normal
.
1.
Apply power to the aircraft and avionics.
2.
Plug headsets into the pilot, copilot, and occupied passenger positions.
