INSTALLATION
SETTING THE SWITCHES FOR THE MULTI-VOLTAGE MODEL ONLY
TWO VOLTAGE SELECTOR SWITCHES
(Not available on U.S. and Canadian models)
Only multi-voltage models are provided with these
switches. U.S. and Canadian models are not provided
with these switches. Mains voltages in Saudi Arabia are
127 V and 220 V only. Never use this model with the 110
V setting in Saudi Arabia.
The line voltage selector switches are on the rear panel. Before
your model is shipped from the factory, these switches are set
to the power requirements of the destination. Check that they
are set properly before plugging the power cord into the
household wall socket. If the voltage is not properly set or if you
move to an area where the voltage requirements differ, adjust
the selector switches as follows.
1. Use a medium-size screwdriver.
2. First, insert the screwdriver in the groove of the voltage
selector at the right, and adjust so that the tip of the groove
points to the voltage value of your area.
3. Next, insert the screwdriver in the groove of the voltage
selector at the left and adjust until the voltage is the same as
at the right.
PAL/NTSC SWITCH
(Not available on U.S. and Canadian models)
This unit uses the TV screen to operate the system. Set the rear
panel PAL/NTSC switch to match your TV’s color system. The
screen will be unclear if the color system does not match.
CHANNEL STEP/FM DE-EMPHASIS SWITCH
(Not available on U.S. and Canadian models)
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 tuned in frequency may be wrong,
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.
(FM 100 kHz/75
µ
s, AM 10 kHz) position:
Set to this position for areas with an FM reception step of 100
kHz, de-emphasis 75
µ
s and AM 10 kHz.
(FM 50 kHz/50
µ
s, AM 9 kHz) position:
Set to this position, for areas with an FM reception step of 50
kHz, de-emphasis 50
µ
s and AM 9 kHz.
NOTE:
When unsure about the channel allocation and de-emphasis
values for your area, consult your dealer for correct information.
