The battery check indicator (BATT. ) will light briefly when a guitar cable is inserted or removed from the output jack. The built-in preamplifier is automatically turned on when a guitar cable is inserted into the output jack. When not using the instrument, or when playing it without amplification, be sure to remove the guitar cable from the output jack so that the preamplifier power is turned off. Also, even when the power is switched off, the system consumes a small amount of power for the tuner standby mode. If the instrument is not going to be used for an extended period of time, we recommend that the battery be removed in order to avoid power consumption or leakage. Accessories 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. r Press the TUNER switch again to switch the tuner OFF. *ThetunerwillautomaticallyswitchOFFapproximatelytwominutesaftertheTUNERswitch ispressed(energysavingfunction).
