Precautions
WARNING
Installation
• Connect this unit's power cord only to an AC outlet of the
type stated in this Owner's Manual or as marked on the
unit. Failure to do so is a fire and electrical shock
hazard.
• Do not allow water to enter this unit or allow the unit to
become wet. Fire or electrical shock may result.
• Do not place a container with liquid or small metal
objects on top of this unit. Liquid or metal objects inside
this unit are a fire and electrical shock hazard.
• Do not place heavy objects, including this unit, on top of
the power cord. A damaged power cord is a fire and
electrical shock hazard. In particular, be careful not to
place heavy objects on a power cord covered by a
carpet.
Operation
• Do not scratch, bend, twist, pull, or heat the power cord.
A damaged power cord is a fire and electrical shock
hazard.
• Do not remove the unit's cover. You could receive an
electrical shock. If you think internal inspection,
maintenance, or repair is necessary, contact your
dealer.
• Do not modify the unit. Doing so is a fire and electrical
shock hazard.
• If lightning begins to occur, turn off the power switch of
the unit as soon as possible, and unplug the power
cable plug from the electrical outlet.
• If there is a possibility of lightning, do not touch the
power cable plug if it is still connected. Doing so may be
an electrical shock hazard.
In case an abnormality occurs during operation
• If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the
unit with a damaged power cord is a fire and electrical
shock hazard.
• Should this unit be dropped or the cabinet be damaged,
turn the power switch off, remove the power plug from
the AC outlet, and contact your dealer. If you continue
using the unit without heeding this instruction, fire or
electrical shock may result.
• If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the unit,
turn it off immediately. Remove the power cord from the
AC outlet. Consult your dealer for repair. Using the unit
in this condition is a fire and electrical shock hazard.
CAUTION
Installation
• Keep this unit away from the following locations:
- Locations exposed to oil splashes or steam, such as
near cooking stoves, humidifiers, etc.
- Unstable surfaces, such as a wobbly table or slope.
- Locations exposed to excessive heat, such as inside
a car with all the windows closed, or places that
receive direct sunlight.
- Locations subject to excessive humidity or dust
accumulation.
• Hold the power cord plug when disconnecting it from an
AC outlet. Never pull the cord. A damaged power cord is
a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is
a potential electrical shock hazard.
Operation
• Turn off all musical instruments, audio equipment, and
speakers when connecting to this unit. Use the correct
connecting cables and connect as specified.
• If you know you will not use this unit for a long period of
time, such as when going on vacation, remove the
power plug from the AC outlet. Leaving it connected is a
potential fire hazard.
Maintenance
• To prevent electrical shock when cleaning the unit,
remove the power plug from the AC outlet.
• The inside of the unit should be cleaned periodically.
Dust accumulation inside the unit may cause
malfunction and is a potential fire hazard. Consult your
dealer for information about cleaning.
PRECAUTIONS FOR OPERATION
- FOR CORRECT OPERATION -
Interference with other electronic devices
• The digital circuits of this unit may induce a slight noise
into nearby radios and TVs. If noise occurs, relocate the
affected equipment.
Backup battery
• The REV500 has a long-life lithium battery that
maintains the contents of the user memory even when
the REV500 is off. Under normal use, the battery should
last several years. However, Yamaha strongly
recommends that you have the battery replaced by a
qualified Yamaha service center every five years, to
prevent the accidental loss of valuable data.
• Should the battery’s voltage fall below a certain level, the
message “LOW BATTERY” will appear in the LCD when
you turn the REV500 on. If this happens, it means that
contents of your REV500’s user memory have been lost.
Have the backup battery replaced immediately.
• Prompt and regular replacement of the back-up battery
is necessary to prevent the loss of important data. In
addition, if possible, you should use the MIDI bulk dump
function (see page 17) regularly to store backup copies
of your REV500’s data in a MIDI sequencer other MIDI
device. This will allow you to recover your data should
the back-up battery run down sooner than you think.
