Mounting the Unit

      Caution

 Never mount the unit in any of the following locations 

to avoid damage due to overheating;

  • Near the heater port. 
  •  Places like the dashboard or rear deck, where it may 

be exposed to direct sunlight. 

 Do not mount the unit near the door, where it could 

be exposed to rain. 

 You run the risk of interfering with the mounting or 

causing damage by drilling into the gas tank, a wiring 
harness, or other component. 

 Keep a safe distance between the unit and other 

electronic equipment. 

 If this unit is operated at a high output continuously, 

the upper side of the unit will get very hot. Do not 
touch it nor place anything on top of the unit. 

 When a short circuit occurs, such as in the speaker 

output terminal, etc. the overload protection circuit 
will operate. This circuit protects the power amplifi er 
from further damage when a short circuit occurs. 
Operation will temporarily stop. In this case, check 
the cause of the short-circuit and if the problem is 
fi xed, normal operation will resume. 

 Since the power amplifi er has a very large output, the 

unit should be installed in the trunk of your car. 

 Do not install this unit under a carpet, otherwise the 

unit may fail because of immature heat dissipation.

 Use the spacer included when installing the unit so 

that the fan and air hole on the base side of the unit 
are not covered. <CY-PAD1003W>

  If the fan and air hole on the base side of the unit are 

covered, the unit will become extremely hot and may 
fail.
