GENERAL INFORMATION AND SAFETY PRECAUTIONS
1-1. GENERAL SAFETY PRECAUTIONS
The following general safety precautions are not related to any specific procedures and therefore do
not appear elsewhere in this publication. These are recommended precautions that personnel must
understand and apply during many phases of operation and maintenance.
WARNING
Keep away from live circuits. Operating personnel must at all times observe all
safety regulations, to prevent serious injury or death due to electrical shock.
Do not service or adjust alone. Under no circumstances should any person service
or adjust the equipment except in the presence of someone who is capable of
rendering aid.
Personnel working with or near high voltages should be familiar with modern
methods of resuscitation.
1-2 SPECIFIC WARNINGS
The following specific precautions are related to inspecting and removing the antenna.
WARNING
Ensure that the transmitting equipment is de-energized prior to inspection of the
antenna. Make sure the test equipment is properly grounded, to prevent electric
shock.
CAUTION
Make sure the antenna is properly supported before removing its mounting hardware.
CAUTION
Do not coat the insulator with any substance; do not paint with lead base paints.
