Auto Stereo Power  (120-1869)       Operation          Faxback Doc. # 15006
Booster

The AUTO STEREO POWER BOOSTER operates easily.  Simply press the ON button
and the lamp will light.  The switch from the lamp turns on the Booster.
When the switch is out, the Booster is not on and you'll hear only the
un-boosted sound from your radio/tape player.

NOTE:  If the lamp fails to light when you turn the power on, the fuse may
       be blown.  Check it.  For replacement, use only a fuse of the same
       size and type.  (Do not use a higher amperage fuse.)

Installation Note:

You can connect either the electrical wiring or install your Booster
first - whichever is most convenient for you.

If you're unsure about performing the installation after reading the
following instructions (if you have questions such as, "is my car negative
ground?"  or "which cord is the power cord?"), we suggest you have the
Booster installed by a qualified technician.  Improper wiring of the Power
Booster could damage the electrical system of your car.

ELECTRICAL WIRING

Disconnect the power cable from the radio or tape player and plug it into
the connector at the back of the Booster.  Plug the appropriately marked
power cable from your Booster into the connector at the back of the radio
or tape player.

If the existing fuses for your radio or tape player are 2A or 3A, use a 7A
fuse between the Booster and the 12-volt power source.  If either the radio
or the tape player comes with 4A or 5A fuses, then use a 10A fuse between
the Booster and the power source (the fuse to a 12-volt power source must
always be higher than the rating of the fuse for the radio or tape player).

NOTE:  2A fuses are supplied with the Booster.  Change, as required, if
       the radio or tape player uses a fuse other than a 2A.

CAUTION:  If the radio or tape player requires a connector that differs
          from the one on the Booster, we suggest you take the vehicle to a
          qualified electronics service technician and have him/her rewire
          as necessary.  S/he may find our Universal Car Stereo Connector
          (Cat No.  270-017) helpful in making these connections.

NOTES:  To assure proper operation of this Stereo Power Booster, you must
        use separate leads for each speaker connection.  Don't use chassis
        ground (or other common ground connection) as a common ground for
        the minus (-) lead of both speakers.  Also, keep right and left
        speaker ground/common leads separated.  (Don't interchange there
        wires.)

If you hear strange sounds from the system wiring, try interchanging the
ground leads between speakers (the leads going to minus (-) terminals of
the speakers).

Connect the single black wire that comes from the back of the Booster to
the frame of the vehicle or to the negative side of the battery.  If you
have a ground wire connected from your radio/tape player, you can leave
it connected.
