PROTECTION CIRCUIT

For some 6 to 10 seconds after the receiver is

switched ON, no sound will be heard. This is

due to the operation

of protection

circuits

which

are

designed

to safeguard

transistors

and

speakers

from

possible

damage

due

chiefly

to switching transients,

etc. Should

the

receiver

remain

silent

for

considerably

longer

than this, switch

off and check

the

Speaker

system

connections.

Should

the

receiver

suddenly

silent

while

you

are

listening

to it, and

a continuous

series of

"clicks"

can

be heard

from

relay contacts

opening and closing within the receiver, this

can be an indication of a short circuit in the

speaker system connections.

Switch off, and

re-check the speaker system impedances, etc.

The protection circuit re-sets itself automat-

ically, so that normal operation is resumed as

soon as the fault is corrected.

Depress the FM function button.

Slightly

turn the VOLUME

control

clockwise

direction to obtain the sound.

Select the broadcasting station with the tuning

knob.

Adjust so that the signal meter pointer

deflects as far to the right as possible and the

tuning meter

pointer is centered,

as indicated

in Fig. 10.

Press

the

MUTING

button

if the signals

from the station are weak.

If the program is being broadcast in stereo, the

STEREO indicator will come on.

. Adjust the volume

with the VOLUME

control.

. To adjust the tone, first set the TONE switch to

ON, and then adjust the BASS

and TREBLE

controls for the preferred bass and treble levels.
