IMPORTANT SAFETY INSTRUCTIONS

CAUTION:

To reduce the risk of electric shock, do not remove

the  top  cover  (or  the  rear  section).  No  user

serviceable parts inside; refer servicing to qualified

personnel.

WARNING:

To reduce the risk of fire or electric shock, do not

expose this appliance to rain and moisture.

This symbol, wherever it appears, alerts you to the

presence of uninsulated dangerous voltage inside

the  enclosure—voltage  that  may  be  sufficient  to

constitute a risk of shock.

This  symbol,  wherever  it  appears,  alerts  you  to

important operating and maintenance instructions

in  the  accompanying  literature.  Please  read  the
