Lightning hazards
Before opening the transmitter and touching internal parts, remove and solidly ground the antenna
connection.
RF hazards
A serious RF hazard and very high voltages exist in the vicinity of the antenna and its networks
during normal operations.
Toxic hazards
Some devices used in this equipment contain beryllium oxide ceramic, which is non-hazardous during
normal device operation and under normal device failure conditions. These devices are specifically
identified with “(BeO)” in the
Description column of the Troubleshooting Manual’s parts list(s).
Do not cut, crush or grind devices because the resulting dust may be hazardous if inhaled.
Unserviceable devices should be disposed of as harmful waste.
Physical hazards
DANGER - MOVING BLADES
Fan blades can cause injury. Lock out power before removing safety features.
Other hazards
Ensure that appropriate fire alarms and fire extinguishers are available. Extinguishers must be suitable
for use on electrical fires.
Many other site safety risks exist. It is beyond the scope of this manual to identify all the risks and
procedures.
WARNING: It is not enough to ground the antenna terminal with the
antenna still connected. Even a small impedance in the ground strap
will result in lethal voltages during a lightning strike.
