OVERLOADING

Do not overload wall outlets, extension cords or convenience 

receptacles beyond their capacity, since this can result in fire 

or electric shock.

 

An appliance and cart combination  

 

should be moved with care. Quick  

 

stops, excessive force and uneven  

 

surfaces may cause the appliance and  

 

cart combination to overturn. 

Do not place the electronic equipment onto the unstable 

table or stand.

 It is because it would fall easily from the 

unstable table or stand, so it may cause accident including 

personal injuries and 

damage the equipment. 

Please follow our instructions 

to install the equipment, or 

you may hire a professional 

technician to handle the 

installation for safety 

purpose.

Do not store the electronic equipment near water or area 

with moisture

 such as bathroom, kitchen sink, laundry area 

and swimming pool, etc.

Do not place the electronic equipment near heat sources

 

such as stoves, radiators and heaters, etc. Placing the 

electronic equipment too near to these heat sources would 

result in damaging the equipment and causing fire. 

120V AC-POWER

Do not place the set on an unstable cart, stand, tripod, 

bracket, or table.

 The set may fall, causing serious injury to a 

child or an adult and serious damage to the set. Use only a 

cart stand tripod, bracket, or table recommended by the 

manufacturer.

For the set with a three-wire grounding type ac plug:

This plug will only fit into a grounding-type power outlet. 

This is a safety feature. If you are unable to insert the plug 

into the outlet, contact your electrician to have a suitable 

outlet installed. Do not defeat the safety purpose of the 

grounding plug.

Do not transport the electronic equipment by yourself if its 

weight exceeds 70 pounds.

 It is recommended that two 

people work together to transport the equipment or by using 

hand truck and the like.

Do not place the electronic 

equipment directly under sunlight 

or close to the window.

 It may 

cause overheat on the electronic 

equipment by the sunlight.

Do not block the openings and vents in the cabinet which 

is designed for the ventilation of the electronic equipment.

 

The blocking may cause overheat in the electronic equipment 

because of insufficient circulation of air, so it would damage 

the electronic equipment.
