Yamaha APX7 Owner's Manual
BATTERY REPLACEMENT
Be sure to replace the battery as soon as possible when the battery check
indicator lights in order to avoid reduced sound quality.
* Be sure to remove the battery if the instrument will not be used for
an extended period of time in order to prevent possible damage
due to battery leakage.
THE CONTROLS
The output jack is an EIAJ-standard 1/4" phone jack. Be sure to use
an appropriate connection cable.
The built-in preamplifier is automatically turned on when a plug is
inserted into the output jack. When not using the instrument, or
when playing it without amplification, be sure to remove the plug
from the output jack so that the preamplifier power is turned off.
Always set the VOLUME control to “0” when plugging in or
unplugging the connection cable.
The battery check indicator (BATT.) will light briefly when a plug is
inserted or removed from the output jack. This is normal and does
not indicate a malfunction.
Be sure to remove the battery if the instrument will not be used for
an extended period of time in order to prevent possible damage due
to battery leakage.
