MRX7-D Owner’s Manual 5
Backup battery
• Do not replace the backup battery by yourself. Doing so
may cause an explosion and/or damage to the device(s).
When the backup battery is running low, the [PRESET]
display indicates “12.” In this case, contact your Yamaha
dealer and have qualified Yamaha service personnel
replace the backup battery.
NOTICE
To avoid the possibility of malfunction/ damage to the product, damage to data, or damage to other property, follow the notices below.

Handling and Maintenance
• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Otherwise, the device,
TV, or radio may generate noise.
• Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car
during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel.
• When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wip-
ing cloths.
• Condensation can occur in the device due to rapid, drastic changes in ambient temperature—when the device is moved from one
location to another, or air conditioning is turned on or off, for example. Using the device while condensation is present can cause dam-
age. If there is reason to believe that condensation might have occurred, leave the device for several hours without turning on the
power until the condensation has completely dried out.
• When turning on the AC power in your audio system, always turn on the power amplifier LAST, to avoid speaker damage. When turn-
ing the power off, the power amplifier should be turned off FIRST for the same reason.
• Always turn the power off when the device is not in use.

Saving data
This device has a built-in backup battery that maintains data in internal memory even when the device’s power is switched off. The backup
battery will eventually become depleted, however, and when that happens the contents of the internal memory will be lost.* To prevent loss
of data be sure to replace the backup battery before it becomes fully depleted. If the backup battery runs low, alert number “12.” will appear
in the [PRESET] display either while the unit is starting up. If this occurs, do not turn off the power, but immediately save the data to a com-
puter or other external storage device, and then have qualified Yamaha service personnel replace the backup battery. The average life of
the internal backup battery is approximately five years, depending on operating conditions.
* Data items maintained in the internal memory by the backup battery are as follows:
• Contents of the current preset and the preset number
• Parameters specific to the unit (e.g., configuration data)
• Current parameters for peripheral devices within the same system
• Event log
Data items other than those described above are stored in memory that does not require backup power, and will be retained even if the
backup battery fails.
