Precautions - Technics SA-DX1050 Operating Instructions Manual

PRECAUTIONS

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
supply 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 safety feature. If
you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail 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. Nonuse 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.
Installation
Environment
1. Outdoor Antenna Grounding — If an outside antenna is
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Section 810 of the National
Electrical Code, ANSI/NFPA No. 70-1990, provides information
with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode. See figure below.
