This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Pad 15 of the FCC
Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communi-
cations. However, there is no guarantee that interference will not
occur in a particular instagation. If this equipment does cause
harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the fol-
lowing measures:
• Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help
Any unauthodzad changes or modifications to this equipment
would void the user's authority to operate this device.
This device complies with Part 15 of the FCC Rules. Operation
is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause
undesired operation.

Precautions
Before using this unit please'read these operating instructions cere-
fully. Take spemal sere to follow the warnings indicated on the unit
itself as well as the safety suggestions listed below.
Afterwards keep them handy for future reference.
1. Power Source -- The unit should be connected to power sup-
ply only of the type descdbed in the operating instructions or as
marked on the unit.
2. Poladsation -- If the unit is equipped with a peladzed 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 revers-
ing the plug. If the plug should still fail to fit, contact your electri-
cian 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 pieced 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, tum the power
off. When left unused for a long period of time, the unit should
be unplugged from the household AC outtst.

position does not interfere with its proper ventilation. Allow 10
cm (4") clearance from the rear of the unit.
2. Foreign Material -- Care should be taken so that objects do not
fall into and liquids are not spilled into the unit. Do not subject
this unit to excessive smoke, dust, mechanical vibration, or
shock.
3. Magnetism -- The "unitshould be situated away from equipment
or devices that generate strong magnetic fields.
4. Stacking -- Do not place heavy objects, other than system
components, on top of the unit.
5. Surface -- Place the unit on a fiat, level surtace.
6. Carla and Stands -- The unit should be used only with a cart or

awall or ceiling, unless specified in this operating instructions.
==
Environment I
1. Outdoor Antenna Grounding -- If an outside antenna is con-
nected 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 struc-
ture, 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.
