Maintenance 

The 

DAP Audio 

DSA requires almost no maintenance. However, you should keep the unit clean. 

Disconnect the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in 
liquid. Do not use alcohol or solvents. 
Keep connections clean. Disconnect electric power, and then wipe the DMX and audio connections 
with a damp cloth. Make sure connections are thoroughly dry before linking equipment or supplying 
electric power.

Replacing a Fuse 

Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the 
fuse burns out, the product will not function whatsoever. If this happens, 

follow the directions below to do 

so.

1.

 Unplug the unit from electric power source. 

2.

 Insert a screwdriver into the slot in the fuse cover. Turn the screwdriver to the left, at the same time  

    gently push a bit (Turn and Push). The fuse will come out. 

3.

 Remove the broken fuse. If brown or unclear, it is burned out. 

4.

 Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse cover.  

    Be sure to use a fuse of the same type and specification. See the product specification label for  
    details.
