Note to CATV system installer
This reminder is provided to call the CATV system installer’s attention
to Article 820-22 of the NEC that provides guidelines for proper
grounding and, in particular, specifies that the cable ground shall be
connected to the grounding system of the building, as close to the point
of cable entry as practical.
LINE VOLTAGE SELECTOR SWITCH
Only multi-voltage models are provided with this switch.
U.S., Canadian, European, U.K., and Australian models
are not provided with this switch. Mains voltages in
Saudi Arabia are 127 V and 220 V only. Never use this
model with 110 V setting in Saudi Arabia.
You will find the line voltage selector switch on the rear panel. Before
your model is shipped from the iactory, th set to the power
requirements of the destination; r you should check that
itis set properly before plugging the pow: ard inte tHe AC puter. Hf
the voltage is not properly set, or if you move to an area where the
voltage requirements differ, adjust the selector switch as follows. Before
adjusting, disconnect the power cord.

CHANNEL STEP/FM DE-EMPHASIS SWITCH
Only multi-voltage models are provided with this
switch.
The unit has been factory preset to the channel allocation and de-
emphasis value for the area in which it is to be sold. If these values
are set incorrectly, the frequency display may stop at the wrong
frequency, or sound may be distorted, resulting in an inability to
reproduce reception signals at their proper sound quality. For this
reason, be sure to confirm that the values are set correctly before
first using the unit. ate:

| ANTENNA CONNECTIONS
Radio reception is not possible unless the antenna is
properly connected.
The strength of broadcast signals varies from one area to another. Signal
propagation is especially poor in metropolitan areas, where there are
many tall buildings, and in mountainous areas. Proper antenna
installation is vital te good reception.
AM ANTENNA
The AM loop antenna supplied with the tuner should be connected to
the AM antenna terminals. The antenna should be placed at a distance
from the tuner, and should not be allowed to touch metallic objects.
Avoid placing it near CD players, personal computers, television sets,
and other devices generating radio frequencies.
Setting Up the AM Antenna
Installation Location] ’
When set on top of a platform, adjust the orientation as shown in Fig.
A so that optimum reception is achieved.
Location for attachment]
When attaching the antenna to a post or wall, first locate a place in
which optimum reception can be achieved, then attach as shown in
Fig.B, using wood screws.
AM Loop Antenna
Set-up
AM Loop Antenna Connection
The accessory AM loop antenna must be connected to ensure
proper reception.
External AM antenna
indoor AM antenna
Provide a vinyl-coated wire (5 ta 6 meters long). Secure one end to the
AM terminal and the other end to a wall or other high location.
Outdoor AM antenna
if reception is stil poor even when a lead antenna has been stretched
out indoors, stretch out a vinyl-coated wire and secure it outdoors.

Although grounding is not always necessary for reception, it is
recommended for protection against damage from lightning if an outdoor
FM antenna is used. It is also recornmended for reducing noise and hum.
Note:
Never make the ground connection to a gas pipe as sparks could cause
the gas to ignite.
