Yamaha RX11 Owner's Manual page 7

PRECAUTIONS
Avoid placing the RX11 in locations exposed to direct
sunlight or high temperatures, excessively high or low
humidity, high dust concentration, or vibration.
Be sure to connect the RX11 to an AC power supply that
meets the power supply specifications listed on the rear of
the unit.
•
If there is any danger of lightning occurring nearby, remove
the power plug from the wall socket in advance.
•
Be sure to make all connections properly, as described in
the "CONNECTIONS" section below.
To avoid damaging your speakers and other playback
equipment, turn off the power of all related equipment
before making connections.
EFFECTS ON OTHER ELECTRONIC
EQUIPMENT
•
Since this unit incorporates digital circuitry, simultaneous
use of other equipment such as TVs, radios, etc. in close
proximity may cause noise and erroneous operation.
If this occurs, separate the affected units sufficiently to
eliminate the problem. It is also a good idea to use separate
line filters on each piece of equipment.
Do not use excessive force in handling control switches and
knobs.
To avoid broken cords and short circuits, be sure to unplug
all connectors by grasping the respective plugs—NOT the
cords.
Remove the power plug from the AC mains socket if the
unit is not to be used for an extended period of time.
Remove all plugs and connections if the unit is to be trans-
ported, to prevent damage to the cords and jacks.
Do not use solvents such as benzene or paint thinner to
clean the unit. Do not use insecticides or other pressurized
spray products in proximity to the unit. Wipe off the
exterior with soft cloth.
CAUTION
•
The RX11 pattern memory locations 00 through 36 contain
factory-programmed rhythm patterns when the unit is
shipped. Use the SAVE function (described on page **) to
save these patterns on cassette tape or memory cartridge
before programming your own patterns into these locations
in order to prevent loss of the pre-programmed patterns.
