Important!
The installation of a rotatable antenna on a tower system is a dangerous and potentially life-
threatening task, if due care is not taken.
A tower must never be installed in a position where it could fall across power distribution
cables in the event of a catastrophic tower failure during a windstorm or earthquake.
The control cable attached to this rotator could, in the event of a nearby or direct lightning
strike, carry lethal voltages down the cable and into your home. Yaesu strongly recommends
the installation of suitable lightning arrestors on all control cables and coaxial lead-in cables
from your antenna installation. See your dealer for details of available lightning-protection
devices.
If an electrical storm should be reported in your area, quickly unplug the control cable from
the rear of the rotator’s controller box, and disconnect the AC cable from the wall outlet.
Disconnect the coaxial cable(s) from the antenna(s) as well.
Do this only if the lightning is not
in your immediate area, as you could be killed instantly if lightning should strike while you are
holding a cable.
If you have any doubts about your ability to install this rotator safely, enlist the services of a
professional antenna installation company.
