Yamaha PF-500 Manual Do Utilizador

- When using any electrical or electronic product, 

basic precautions should always be followed. These precautions 
include, but are not limited to, the following:

Read all Safety Instructions, Installation Instructions, Spe-

cial Message Section items, and any Assembly Instructions 
found in this manual BEFORE making any connections, includ-
ing connection to the main supply.

Main Power Supply Verification: Yamaha products are 

manufactured specifically for the supply voltage in the area 
where they are to be sold. If you should move, or if any doubt 
exists about the supply voltage in your area, please contact your 
dealer for supply voltage verification and (if applicable) instruc-
tions. The required supply voltage is printed on the name plate. 
For name plate location, please refer to the graphic found in the 
Special Message Section of this manual.

This product may be equipped with a polarized plug (one 

blade wider than the other). If you are unable to insert the plug 
into the outlet, turn the plug over and try again. If the problem 
persists, contact an electrician to have the obsolete outlet 
replaced. Do NOT defeat the safety purpose of the plug. 

Some electronic products utilize external power supplies 

or adapters. Do NOT connect this type of product to any power 
supply or adapter other than one described in the owners manual, 
on the name plate, or specifically recommended by Yamaha.

WARNING: Do not place this product or any other 

objects on the power cord or place it in a position where anyone 
could walk on, trip over, or roll anything over power or connect-
ing cords of any kind. The use of an extension cord is not recom-
mended! If you must use an extension cord, the minimum wire 
size for a 25’ cord (or less) is 18 AWG. NOTE: The smaller the 
AWG number, the larger the current handling capacity. For 
longer extension cords, consult a local electrician.

Ventilation: Electronic products, unless specifically 

designed for enclosed installations, should be placed in locations 
that do not interfere with proper ventilation. If instructions for 
enclosed installations are not provided, it must be assumed that 
unobstructed ventilation is required.

Temperature considerations: Electronic products should 

be installed in locations that do not significantly contribute to 
their operating temperature. Placement of this product close to 
heat sources such as; radiators, heat registers and other devices 
that produce heat should be avoided.

tions and should not be used near water or exposed to rain.

supplied or; a cart, rack, or stand that is recommended by the

safety markings and instructions that accompany the accessory 
product.

The power supply cord (plug) should be disconnected 

from the outlet when electronic products are to be left unused for 
extended periods of time. Cords should also be disconnected 
when there is a high probability of lightning and/or electrical 
storm activity.

Care should be taken that objects do not fall and liquids are 

not spilled into the enclosure through any openings that may exist.

Electrical/electronic products should be serviced by a 

qualified service person when:

amplifier and headphones or speaker/s, may be capable of pro-
ducing sound levels that could cause permanent hearing loss. DO 
NOT operate for a long period of time at a high volume level or 
at a level that is uncomfortable. If you experience any hearing 
loss or ringing in the ears, you should consult an audiologist. 
IMPORTANT: The louder the sound, the shorter the time period 
before damage occurs.
