Handling and maintenance

• Do not connect this product to a public Wi-Fi and/or Internet

through a router with strong password protections. Consult 
your router manufacturer for information on optimum 
security practices.

• Do not use the product in the vicinity of a TV, radio, or other 

electric products. Otherwise, the product, TV, or radio may 
generate noise.

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

extreme cold or heat, in order to prevent the possibility of 
panel disfiguration, unstable operation, or damage to the 
internal components.

• Do not install in locations where temperature changes are 

severe. Otherwise, condensation may form on the inside or 
the surface of the product, causing it to break.

• If there is reason to believe that condensation might have 

occurred, leave the product for several hours without turning 
on the power until the condensation has completely dried 
out, in order to prevent possible damage.

use paint thinners, solvents, cleaning fluids, or chemical-
impregnated wiping cloths, since this might cause alteration 
or discoloration.

Doing so might cause problems with electrical contact or 
fader motion.

Saving data

• When changing the battery for the clock, please contact the 

Yamaha service personnel. This product has a built-in battery 
for the clock, so even when the power supply is interrupted, it 
maintains the time data of the internal clock. When the clock 
battery wears out the time data is lost, resulting in time-
related data, such as for scenes, saved in the product, to be 
lost. The expected life of the clock battery is 5 years, but may 
vary with the usage environment.

• To protect against data loss through media damage, we 

recommend that you save your important data onto two USB 
storage devices/external media.
