MMP1 Getting Started

 CAUTION

Always follow the basic precautions listed below to 
avoid the possibility of physical injury to you or others, 
or damage to the device or other property. These 
precautions include, but are not limited to, the 
following:

Power supply/power cord 

• When removing the electric plug from the device or an 

outlet, always hold the plug itself and not the cord. Pulling 
by the cord can damage it.

• To disconnect the device from the mains, unplug both 

power cords.

Location

• Do not place the device in an unstable position where it 

might accidentally fall over and cause injuries.

• Do not block the vents. This device has ventilation holes at 

the sides to prevent the internal temperature from becoming 
too high. In particular, do not place the device on its side or 
upside down. Inadequate ventilation can result in 
overheating, possibly causing damage to the device(s), or 
even fire.

• Do not place the device in a location where it may come into 

contact with corrosive gases or salt air. Doing so may result 
in malfunction.

• Before moving the device, remove all connected cables.

• If the device is mounted in an EIA standard rack, carefully 

read the section “Precautions for rack mounting” on 
page 13. Inadequate ventilation can result in overheating, 
possibly causing damage to the device(s), malfunction, or 
even fire.

Maintenance

• Remove the power plug from the AC outlet and also 

disconnect the connected power supply from the [BACKUP 
DC INPUT] connector when cleaning the device.

Handling caution

• Avoid inserting or dropping foreign objects (paper, plastic, 

metal, etc.) into any gaps or openings on the device (vents). 
If this happens, immediately turn off the power and then 
unplug the power cord from the AC outlet, and have the 
device inspected by qualified Yamaha service personnel.

• Do not rest your weight on the device or place heavy 

objects on it. Avoid applying excessive force to the buttons, 
switches or connectors to prevent injuries.

• Avoid pulling the connected cables to prevent injuries or 

damage to the device.

Backup battery

• Do not replace the backup battery by yourself. Doing so 

may cause an explosion and/or damage to the device(s).
When the backup battery needs to be replaced, the error 
icon will appear on the menu bar of the MMP1 Editor while 
the MMP1 is connected to the MMP1 Editor. In this case, 
contact your Yamaha dealer and have qualified Yamaha 
service personnel replace the backup battery.

NOTICE

To avoid the possibility of malfunction/ damage to the product, 
damage to data, or damage to other property, follow the 
notices below.

Handling and maintenance

• Do not use the device in the vicinity of a TV, radio, AV 

equipment, mobile phone, or other electric devices. 
Otherwise, the device, TV, or radio may generate noise.

• Do not expose the device to excessive dust or vibration, or 

extreme cold or heat (such as in direct sunlight, near a 
heater, or in a car during the day), in order to prevent the 
possibility of panel disfiguration, unstable operation, or 
damage to the internal components.

• Do not place vinyl, plastic or rubber objects on the device, 

since this might discolor the panel.

• When cleaning the device, use a dry and soft cloth. Do not 

use paint thinners, solvents, cleaning fluids, or chemical-
impregnated wiping cloths.

• Condensation can occur in the device due to rapid, drastic 

changes in ambient temperature—when the device is 
moved from one location to another, or air conditioning is 
turned on or off, for example. Using the device while 
condensation is present can cause damage. If there is 
reason to believe that condensation might have occurred, 
leave the device for several hours without turning on the 
power until the condensation has completely dried out.

• The rubber feet included in this package can be attached to 

the device to prevent slippage when it is to be used on a 
slippery surface.

• Always turn the power off when the device is not in use.

• Even when the both (

P

) [MAIN] switch and (

P

) [BACKUP] 

switch are in standby status (power indicators are off), 
electricity is still flowing to the instrument at the minimum 
level. When you are not using the instrument for a long time, 
make sure you unplug the power cord from the wall AC 
outlet, and also disconnect the connected power supply 
from the [BACKUP DC INPUT] jack.

Yamaha cannot be held responsible for damage caused 
by improper use or modifications to the device, or data 
that is lost or destroyed.
