INSPECTION
l Take out the plug, and check for a worn edge on the
element spot connection, and for shreds of tobacco or
other material on the element.
l Using an ohmmeter, check the continuity of the element.
l Confirm that there is no dirt on the surface of the socket.
CAUTIONS FOR USE OF THE CIGARETTE LIGHTER SOCKET
AS AUXILIARY POWER SOURCE
1. When using a “plug-in” type of accessory, do not use
anything with a load of more than 120W.
2. It is recommended that only the lighter be inserted in
the receptacle.
Use of “plug-in” type accessories may damage the
receptacle and result in poor retention of the lighter.
NOTE
The specified load should be strictly observed, because
overloaded cord burns the ignition switch and herness.

ANTkNNA TRUMMER NOBNIAA

1.
2.
3.
4.
5. The antenna trimmer is essential for matching the antenna
with the radio in order to obtain the maximum sensitivity of
the radio.
It must be adjusted with the antenna actually mounted on
the vehicle. If the trimmer is not adjusted properly, the
radio suffers from not only low sensitivity but also noises,
su’ch as external noise and noise from passing vehicles.
In the following cases, therefore, adjust it as described
below.
(1) When radio is installed.
(2) If antenna is replaced.
(3) If radio has low sensitivity.
(4) If radio is noisy.
AkTENNA TRIMMER ADJUSTMENT
Mgke the following preparations for adjustment:
(1)’ Turn the ignition key to the “ACC” position.
(2) Extend the antenna all the way.
(3) Tune accurately to a station near 1,400 kHz in order to
receive a broadcast in as weak an electric field as can
be barely received. If there is no station near 1,400 kHz,
tune to any high-frequency station (above 1,000 kHz)
available. If there are two or more stations near 1,400
kHz, choose the louder one.
(4) Set the volume control to the proper volume.
(5) Set the tone ccontrol to treble position.
Be sure that preparations 1 through 5 have been correctly
made.
Insert a screwdriver into the trimmer adjusting hole.
Tumrn the screwdriver clockwise or counterclockwise for
maximum sensitivity (maximum broadcast wave sound).
If the optimum sensitivity point cannot be found, check for
an antenna malfunction or a broken wire.
NOTE
The antenna trimmer of an electronic tuning radio does not
require adjustment.
