Avoid placing the RX21 in locations exposed to direct sunlight or high temperatures,
excessively high or low humidity, high dust concentration, or vibration.
Be sure to connect the RX21 to an AC power supply that meets the power supply
specifications listed on the rear of the unit. Ideally, you should use the PA-1 power
supply unit supplied with the RX21.
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 illustrated in the CONNECTIONS diagram.
To
avoid damaging your speakers and other playback equipment, turn off the power
of all related equipment before making connections.
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 transported, 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 a soft cloth.
PRECAUTIONS
The RX21 memory has a Lithium backup battery so that patterns and songs are not lost
when you turn the power off. This battery has a life of about 5 years. When its voltage
level starts to fall below a usable level, the RX21’s LCD will display an Error Message
when you turn it on (see the ERROR MESSAGES section of this manual). In this case,
replacement will be imminent, and you should contact your local Yamaha dealer.
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.
