If none of these suggested remedies solves the problem, return your
scanner to your local Radio Shack store for assistance.

REPLACING A FUSE

If the scanner does not operate, you might need to replace the red power
wire's fuse.  If the memory is lost, you might need to replace the orange
continuous power wire's fuse.

NOTE:  Also check your vehicle's fuses.

Use the following steps to check/change a fuse.

WARNING:  Before you begin, turn off the scanner and your vehicle's
          ignition.

1.  Disconnect the power wire whose fuse you are checking.

2.  Push and twist the fuse holder so that it springs apart.

3.  If the fuse is blown, replace it.  Use only standard 30 mm, 2-amp
    fuses.

4.  Reassemble the fuse holder by pushing and twisting the two parts until
    they snap together.

5.  Reconnect the red power wire to the ACC terminal.  Reconnect the
    orange power wire to the continuous 12-volt power source.
