Yamaha AC1R Manuals

Electric Acoustic Guitar Owner’s Manual PRECAUTIONS l Before connecting the guitar to the amplifier, refer to the “Battery Replacement” section and install the batteries. l Always set the guitar’s VOLUME control and the volume control on the amplifier to their minimum levels when connecting or dis- connecting the cable. l The built-in preamplifier is automatically turned ON when a guitar cable is connected to the output jack. When not using the instru- ment, or when playing it without amplification, be sure to remove the guitar cable from the output jack so that the preamplifier pow- er is turned OFF. Also, if the instrument is not going to be used for an extended period of time, or when battery power is depleted, we recommend that the batteries be removed in order to avoid power consumption or leakage. Thank you for choosing a Yamaha electric-acoustic guitar. In order to make the most of the advanced features and perfor- mance provided by your guitar, please read this manual care- fully before using the instrument.
