instructions Ow,
Thank you for buying this Pioneer product.
Please read through these operating instructions so you will know how
to operate your model properly. After you have finished reading the
instructions, put them away in a safe place for future reference.
in some countries or regions, the shape of the power plug and power
outlet may sometimes differ from that shown in the explanatory
drawings. However, the method of connecting and operating the unit
is the same.
WARNING: 70 prevent FIRE OR SHOCK HAZARD, DO LINE VOLTAGE SELECTOR SWITCH
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. Only multi-voltage models are provided with this switch. U.K.
models are not provided with this switch.
Main voltages in Saudi Arabia are 127 V and 220 V only.
Never use this mode! with a 110 V setting in Saudi Arabia.
The line voltage selector switch is on the rear panel. Before your
model is shipped from the factory, this switch is set to the power
requirements of the destination. Check that it is set properly before
plugging the power cord into the AC wall socket. If the voltage is not
properly set or if you move to an area whe re the voltage
requirements differ, adjust the selector switch as follows.
1. Use a medium-size screwdriver.
2. Insert the screwdriver into the groove on the voltage Clor,
and adjust so that the tip of the arrow points to the voltage value
of your area.
Set the voltage selector for the voltage in your area.

FM/AM CHANNEL STEP SWITCH
FM/AM CHANNEL STEP switch is located on the rear panel of the
digital synthesizer tuner. Before the tuner leaves the factory, this
switch is setto the channel allotment plan of the area in which the
tuner is sold. When TUNING button is given a single push, the
frequency display will change in following unit.

and AM 10 kHz.
[50 kHz/9 kHz] position:
Set to this position for areas with FM reception step of 50 kHz and
AM 9 kHz.
NOTE:
When unsure about the channel allocation for your area, consult
your dealer for correct information.
The channel step will not change if CHANNEL STEP switch is
operated with the power ON.
After operating CHANNEL STEP switch, if you turn POWER
switch OFF and then ON again, the channel step will switch over.
If you operate CHANNEL STEP switch, the stations that were
memorized before the switch was operated will be erased.
INSTALLATION
LOCATION
Instail the unit in a well-ventilated location where it will
not be exposed to high temperature or humidity.
Do not install the unit in a location which is exposed to direct
sunlight, or near hot appliances or radiators. Excessive heat can
adversely affect the cabinet and internal components. Installation of
the unit ina damp or dusty environment may resultin malfunction or
accident. (Also, avoid installation near cookers, etc., where the unit
may be exposed to smoke from oil, steam or heat.)
CONDENSATION
When this unit is brought into a warm room from previously cold
surroundings or when the room temperature rises sharply,
condensation may form inside, and the unit may not be able to attain
its full performance. If this occurs, allow the unit to stand for about
an hour or raise the room temperature gradually.

POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by tugging
the cord and never touch the power cord when your hands are wet as
this could cause a short circuit or electric shock. Do nat place the unit,
a piece of furniture, etc., on the power cord, or pinch the cord. Never
make a knot in the cord or tie it with other cords. The power cords
should be routed such that they are not likely to be stepped on. A
damaged power cord can cause fire or give you an ¢' al shock,
Check the power cord once in a while, When you find it damaged, ask
your nearest PIONEER authorized service center or your dealer for a
replacement.
MAINTENANCE OF EXTERNAL SURFACES
e Use a polishing cloth or dry cloth to wipe off dust and dirt.
| @When the surfaces are very dirty, wipe with a soft-cloth dipped
in some neutral cleanser diluted five or six times with water and
i wrung out well, then wipe again with a dry cloth. Do noi use
furniture wax or cleaners.
eNever use thinners, benzine, insecticide sprays and other
chemicals on or near this unit, since these will corrode the
surfaces.

FEATURES
@ FM IF bandwidth switchable between “normal”
and “super narrow” for FM.
@ D.D.D. (Digital Direct Decoder), for a high SN ratio.
@ A built-in attenuator (RF ATT) can be switched on
or off for proper reception of strong broadcast
stations.
# Random 36-stations Presetting
A total of 36 FM and AM stations can be preset into the memory
circuit.
@ Even the slightest deterioration of sound quality is
avoided by the thorough use of anti-vibration parts.

ANTENNA CONNECTIONS
Radio reception is not possibile unless the antenna
is properly connected.
The strength of broadcast signals varies from one area to another.
Signal reception is especially poor in metropolitan areas, where
there are many tall buildings, and also in mountainous areas. Proper
antenna installation is vital to 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
¢ Insert the clip on the bottom of the antenna into the groove on the leg.
To permanently fix the antenna, screw the leg to a wail or post
before assembling (fixing the antenna in the direction that gives
the best reception),
@Place the antenna on a level surface and rotate it to locate the
orientation that yields the best reception.
AM Loop Antenna Set-up
AM Loop Antenna Connection
The accessory AM loop antenna must be
connected to ensure proper reception.
ome
External AM antenna
indoor AM antenna
Provide a vinyl-coated wire (5 to 6 meters long). Secure one end to
the AM terminal and the other end to a wall or other high location.
Outdoor AM antenna
Ifreception is still poor even when a lead antenna has been stretched
out indoors, stretch out a vinyl-coated wire and secure it outdoors.

External FM antenna installation
Use an external antenna when the signals from the station are weak
and cannot be picked up by the accessory T-type FM antenna, or
when the sound heard is accompanied by too much noise. There are
two ways of connecting the external FM antenna to the ANTENNA
terminals: with 300 feeder wire, or with a 75 Q coaxial cable. It is
recommended that you use the 75 Q coaxial cable, so that the effects
of extraneous noise are reduced to a minimum,

is a 75 Q coaxial cable

the IF bandwidth, and for FM broadcasts, use
MPX MODE button to select the AUTO or MONO
mode, based on reception conditions.
Note on Auto Tuning
e Because of high sensitivity of this unit, it may automatically stop
even at very weak overseas stations. The same can happen with
aggregate radio noise emitted in cities.
© During reception of an AM broadcast, if it frequently stops when
presetting stations with auto tuning, auto tuning of only strong
local stations is possible by changing the direction of the loop
antenna or folding it down.
After presetting, move the loop antenna back to the position where
it is pointing in the best direction as before.
@ Preset extremely weak stations with manual tuning
The Signal indicator
When no segment of the signal indicator is lit, reception is not
possible even if the tuning frequency is correct. This is because the
antenna terminal input is too weak. Check whether th
cable is firmly connected. If it is, consult your nearest dealer and
install an outdoor antenna.
