maintenance to qualified Yamaha service personnel. Opening
the case and/or tampering with the internal circuitry voids
the warranty.
5.
Always power off before making connections
Always turn the power OFF before connecting or
disconnecting cables. This is important to prevent damage to
the unit itself as well as other connected equipment.
6.
Handle cables carefully
Always plug and unplug cables — including the AC power
cord — by gripping the connector, not the cord.
7.
Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the
unit. Wipe clean with a soft, dry cloth.
8.
Always use the correct power supply
Make sure that the power supply voltage specified on the rear
panel matches your local AC mains supply. Also make sure
that the AC mains supply can deliver more than enough
current to handle all equipment used in your system.
9.
Do not touch the heatsink when the EMX640 is in use.
It can get very hot.
Precautions
1.
Avoid excessive heat, humidity, dust and vibration
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity — such as near
radiators, stoves, etc. Also avoid locations which are subject
to excessive dust accumulation or vibration which could
cause mechanical damage.
2. Ventilation
Allow a distance of 30 cm between the unit and the wall so
that heat generated from the unit will be released effectively.
Also, allow enough space between the unit and other devices.
If you mount the unit in an audio rack, keep a space of 40
cm on the top panel, and a space of 15 cm to the side panel.
Remove the rear panel of the rack or open a vent hole. If heat
release is inadequate, the unit will retain heat inside the unit,
which may cause a fire.
3.
Avoid physical shocks
Strong physical shocks to the unit can cause damage. Handle
it with care.
4.
Do not open the case or attempt repairs or modifications
yourself
