TROUBLESHOOTING

Sometimes an operational fault can be mistaken for a malfunction or failure. Check the following points and see if
the symptoms of the trouble are outlined below before you get in touch with the servicemen. If you cannot locate
the symptoms, turn off the power and contact your nearest Pioneer Service Center, Service Station or authorized

Pioneer dealer.

Symptom

Diagnosis check point:

Remedy

No sound

Power switch is STAND-BY.

Power plug is not connected to the power out-
let.

Set to ON.

Connect the plug to the outlet securely.

Cannot receive FM
station.

Function switch does not correspond to the
correct frequency band.

The antenna connecting leads hava worked free.

The input signal level is weak

The signals being picked up are weak and so the
muting circuit has been activated and no sound
is heard.

Set the function switch to the correct fre-
quency band.
Connect firmly to the terminals.

When the FM LOCAL switch is set to ON, try
resetting it to OFF and depressing the TUNING
switch.

Install a highly sensitive antenna outdoors.

Cannot receive AM
station.

Function switch does not correspond to the
correct frequency band.

Signal indicators do not work properly indicat-
ing that signal strength is insufficient.

Set the function switch to the correct fre-
quency bend.

Try changing the position of the bar antenna
or install an outdoor antenna.

Cannot receive
programmed
station even when
the station call
switch is
depressed.

Function switch does not correspond to the
correct frequency band.

Power cord has been disconnected for a long
time (more than 3 days) and so contents of
memory have been erased.

Set the function switch to the correct fre-
quency bands

Perform memory operation again.

Memory function
does not work

After memory indicator goes off. station call
switches are depressed

Depress the station call switch immediately
after depressing the memory switch again.

Intermittent noise
or sound is

The FM antenna is being affected by the multi-
peth phenomenon.

Point the FM antenna properly in the direction
of the transmitting antenna.

NOTE

The specifications of this model differ according to the ship-

ment destination.

e For U. K. (H8 stamped on pecking case); Power line voltage
is 240 volts.

0 For mainland Europe {HE stamped on pecking meal; Power
line voltage is 220 volts

Model: have their line voltage; set in accordance with their

destinatrbn before they are shipped from the factory. The volt-

age which has thus been set is indicated on the rear panel of the

main unit.

Before switching on the power, make absolutely sure that the

voltage tallies with the value used in your area. If it does not

tally or if you move to another area with a different voltage

(such from 220V to 240V or vice versal, get in touch with your

nearest authorized Pioneer Service Center or Service Station or,
