Yamaha ms400 Owner's Manual

 

• Do not allow water to enter this unit or allow the unit 

to become wet. Fire or electrical shock may result.

• Do not place a container with liquid or small metal 

objects on top of this unit. Liquid or metal objects 
inside this unit are a fire and electrical shock hazard.

• Connect the included power cord only to an AC 

outlet of the type stated in this Owner’s Manual or 
as marked on the unit. Failure to do so is a fire and 
electrical shock hazard.

• Do not scratch, bend, twist, pull, or heat the power 

cord. A damaged power cord is a fire and electrical 
shock hazard.

• Do not place heavy objects, including this unit, on 

top of the power cord. A damaged power cord is a 
fire and electrical shock hazard. In particular, be 
careful not to place heavy objects on a power cord 
covered by a carpet.

• Place the device near a power outlet so you can eas-

ily plug it in.

• If you notice any abnormality, such as smoke, odor, 

or noise, or if a foreign object or liquid gets inside 
the unit, turn it off immediately. Remove the power 
cord from the AC outlet. Consult your dealer for 
repair. Using the unit in this condition is a fire and 
electrical shock hazard.

• Should this unit be dropped or the cabinet be dam-

aged, turn the power switch off, remove the power 
plug from the AC outlet, and contact your dealer. If 
you continue using the unit without heeding this 
instruction, fire or electrical shock may result.

• Use only the included power cord for this unit. 

Using other types may be a fire and electrical shock 
hazard.

• The power to this device is not completely shut off 

even when the power switch is turned off. Locate the 
device close to the AC outlet so you can easily reach 
the power plug.

• If the power cord is damaged (i.e., cut or a bare wire 

is exposed), ask your dealer for a replacement. 
Using the unit with a damaged power cord is a fire 
and electrical shock hazard.

• Do not remove the unit’s cover. You could receive an 

electrical shock. If you think internal inspection, 
maintenance, or repair is necessary, contact your 
dealer.

• Do not modify the unit. Doing so is a fire and elec-

trical shock hazard.

• Turn off all audio equipment, and speakers when 

connecting to this unit. Use the correct connecting 
cables and connect as specified. 

• Always lower the volume control to minimum 

before turning on the power to this unit. A sudden 
blast of sound may damage your hearing.

• Allow enough free space around the unit for normal 

ventilation. This should be: 20 cm at the sides, 25 
cm behind, and 30 cm above.
For normal ventilation during use, remove the rear 
of the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up 
inside and may cause a fire.

• This unit is heavy. Use two or more people to carry 

it.

• If you stack the speakers, secure the handles of the 

speakers using a belt and fix the speakers to the floor 
or wall to prevent them from falling and causing 
injury. Do not stack more than two speakers.

• Do not use the handles to suspend the speaker. Oth-

erwise, it may fall, causing injury.

• Hold the power cord plug when disconnecting it 

from an AC outlet. Never pull the cord. A damaged 
power cord is a potential fire and electrical shock 
hazard. 

• Do not touch the power plug with wet hands. Doing 

so is a potential electrical shock hazard.

• XLR-type connectors are wired as follows: pin 1: 

ground, pin 2: hot (+), and pin 3: cold (–).

• Using a mobile telephone near this unit may induce 

noise. If noise occurs, use the telephone away from 
the unit.

• Do not use the speakers at uncomfortably loud 

level. Otherwise, you may damage your hearing.

• If lightning begins to occur, turn off the power 

switch of the unit as soon as possible, and unplug 
the power cable plug from the electrical outlet.

• If there is a possibility of lightning, do not touch the 

power cable plug if it is still connected. Doing so 
may be an electrical shock hazard.
