Portable Power Inverter
(220-0138)                 Operation                  Faxback Doc. # 19630

1.  After connecting power to the power inverter, plug the equipment to be 
    used into the power inverter's AC socket. 

2.  Set the power inverter's switch to ON (1). 

3.  After the inverter's power indicator lights, turn on the connected 
    appliance. 

4.  When you finish using the equipment, turn off both the equipment and 
    the power inverter.  The power indicator light turns off. 

The power inverter stops working if:

    The inverter overheats after supplying more than 220 watts of power. 

    If this happens, disconnect the appliance from the power inverter and 
    wait until the power inverter cools down before using it again. 

    Your vehicle battery output drops below 10 volts.  If this happens, 
    run your vehicle's engine a few minutes to recharge the battery. 

NOTES:  Using a dirty cigarette-lighter socket might cause your vehicle's
        battery to discharge below 10 volts.  If you cannot turn on the
        power inverter, try unplugging it from the cigarette-lighter
        socket, making sure the socket and plug are clean, then
        reconnecting it. 

        If you use the power inverter to power a TV, you might need to 
        press the TV's power button several times before it turns on. 

CHECKING/REPLACING THE POWER INVERTER'S FUSE 

If the inverter does not turn on, or if the power inverter stops working 
after a few minutes of operation, check your power inverter's 30-amp fuse 
and/or your vehicle's cigarette lighter fuse. 

Follow these steps, to check the inverter's 30-amp fuse.

1.  Using a Phillips screwdriver, remove only the four outer screws (at 
    the corners) on the cable end of the power inverter. 

    CAUTION:  Be careful not to remove the blower motor or cable retaining 
              screws. 

2.  Pull out the inverter's end until you can see the flat fuse (about 1 
    3/4 inch). 

3.  Using curved needle nose pliers, carefully pull out the fuse. 

4.  If the fuse is blown, replace it with the supplied 30-amp fuse using 
    the curved needle nose pliers to carefully push in the fuse. 

    CAUTION:  You must replace the power inverter's fuse with a fuse of 
              the same size and rating (such as Cat. No. 270-1085).  Using 
              a fuse with a higher rating could damage your power inverter.

5.  After you replace the fuse, or if the fuse is not blown, push in the 
    inverter's end and secure it by replacing the four outer screws. 

CAUTIONS: If your vehicle's cigarette lighter fuse is blown, you must 
          replace it with a fuse of the same rating, size, and type 
          recommended in your vehicle's owner's manual. 

          Do not replace your vehicle's cigarette-lighter fuse with one
          that exceeds the rating recommended in your vehicle's owner's
          manual or damage to your vehicle's electrical circuits might
          result. 

          Do not replace your vehicle's cigarette-lighter fuse with the
          supplied 30-amp fuse.  The supplied fuse is provided as a
          replacement for your power inverter, NOT your vehicle's
          cigarette-lighter fuse. 

If neither the inverter's nor your vehicle's cigarette lighter fuse is 
blown, take the power inverter to your local Radio Shack store for service.

IMPORTANT NOTICE  If you must connect the power inverter directly to the
                  vehicle battery, have a qualified vehicle mechanic or
                  electrical system installation technician make the
                  connection using large-gauge wire (14-gauge or better).
