2.2 Unpacking and Inspection
Unpack the equipment carefully, and locate the warranty card. Inspect the unit visually
for damage due to shipping and report all such claims immediately to the carrier
involved. Note that each unit should have the following:
- NPX138 Radio

Verify that all items are present before proceeding, and report any shortage immediately

2.3 Installation Procedures
2.3.1 Warnings ← IMPORTANT!
Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any
logic, audio, or DC power lines from this unit with 400 Hz synchro wiring or AC power
lines. Do not position this unit next to any device with a strong alternating magnetic
field such as an inverter or significant interference to operation will result. In all
installations, use shielded cable exactly as shown and ground as indicated.
Significant problems may result if these guidelines are not followed.
2.3.2
Cautions
All audio installations can be severely degraded by incorrect wiring and shielding, and
may result in much higher cross-talk, hum, and ground-loop interference. This should
be considered when audio wiring to and from the radio installation is performed.
