SAFETY 

1. 

It is important to read these instructions, and to follow them. 

2. 

Keep this instruction manual in an accessible place. 

3. 

Clean only with a dry cloth. Cleaning fluids may effect the equipment. 

4. 

Refer all servicing to qualified personnel. Servicing is required when the apparatus has been 
damaged in any way, such as a power supply cord or plug is damaged, liquid has been spilled 
or objects have fallen into the apparatus, the apparatus has been exposed to any rain or 
moisture, does not operate normally or has been dropped. 

5. 

 

WARNING – To reduce the risk of fire or electric shock, do not expose this apparatus 
to rain or moisture. The apparatus shall not be exposed to dripping or splashing and no 
objects filled with liquids, such as vases, shall be placed on the apparatus.

 

 

TO PREVENT ELECTRIC SHOCK DO NOT REMOVE THE 
COVER. THERE ARE NO USER SERVICABLE PARTS 
INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL
