ELECTRIC ACOUSTIC GUITAR Owner's Manual Thank you for choosing a Yamaha electric-acoustic guitar. In order to make the most of the advanced features and performance provided by your guitar, please read this manual carefully before using the instrument. 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.
