ELECTRICAL INTERFERENCE
Since the DEQ7 contains digital circuitry, it may cause interfer­
ence and noise if placed too close to TV sets, radios or similar
equipment. If such a problem does occur, move the DEQ7 further
away firom the affected equipment.
BACKU P BATTERY
The DEQ7 contains a long-life lithium battery which maintains
the contents of the buffer and user memory locations even when
the unit is turned OFF. With normal use the battery should last
for approximately 5 years. If the battery voltage falls below the
safe level, however, the “***WARNING*** LOW BATTERY”
display wiU appear on the LCD when the power is first turned
ON. If this occurs, have the battery replaced by a qualified
Yamaha service center. Do not attempt to replace the battery
yourself.
