Yamaha APX500II Owner's manual
PRECAUTIONS
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.
