Before using this unit please read these operating instructions
carefully.
Take special care to follow the warnings indicated
on
the unit itself as well as the safety suggestions listed below.
Afterwards keep them handy for future reference.
Safety
1. Power Source -- The unit should be connected to power sup-
ply only of the type described in the operating instructions or
as marked on the unit.
2. Polarization
-- If the unit is equipped
with a polarized AC
power plug (a plug having one blade wider than the other),
that plug will fit into the AC outlet only one way. This is a safe-
ty feature.
If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug should still fall to fit,
contact your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
3. Power Cord Protection
-- AC power supply cords should be
routed so that they are not likely to be walked on or pinched
by items placed upon or against them. Never take hold of the
plug or cord if your hand is wet, and always grasp the plug
body when connecting or disconnecting it.
4. Nonuae Periods -- When the unit is not used, turn the power
off. When left unused for a long period of time, the unit should
be unplugged from the household AC outlet.

trical Code, ANSI/NFPA No. 70-1990,
provides information
with respect to proper grounding of the mast and supporting
structure,
