1.  Disconnect the cable from your vehicle's negative (-) battery 
    terminal. 
 
2.  To open either fuse holder, unlatch the two latches on the fuse holder 
    until it springs apart. 
 
3.  Slide off the metal holder on each end of the fuse and remove the 
    fuse. 
 
4.  If the fuse is blown, replace it.  Use only standard 1-1/4 inch fuses 
    with the proper rating.  The red +12V TO IGNITION wire's fuse must be 
    0.5 amps.  The 12V TO BATTERY wire's fuse must be 12 amps. 
 
    CAUTION:  The supplied spare fuses have the correct rating. If you 
              use a fuse with an incorrect rating, the stereo could be 
              damaged. 
 
5.  Reassemble the fuse holder by squeezing it together until it latches. 
 
6.  Reconnect the cable to the vehicle's negative (-) battery terminal.
