[. . . ] AC Adaptor Jack 12 This jack accepts the connection of an AC adaptor (optionally available BOSS PSA-series). By using an AC adaptor, you can play without being concerned about how much battery power you have left. * Use only the specified AC adaptor (PSAseries), and make sure the line voltage at the installation matches the input voltage specified on the AC adaptor's body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock. [. . . ] Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery. For instructions on changing the battery, refer to "Changing the Battery" (p.

Is the battery low or dead? No sound / low volume Is your instrument properly connected to the E-68?The further counterclockwise you turn the LEVEL knob, the more the volume is reduced when the effect is on. Turn the LEVEL knob clockwise to increase the volume. Replace it with a new battery (p. 12). * The battery that is supplied with the unit is for temporary use, intended primarily for testing the pedal's operation. * The use of an AC adaptor is recommended as the unit's power consumption is relatively high. * To prevent unnecessary battery consumption, be sure to disconnect the plug from the INPUT jack and the BRIGHT IN jack when not using the effects unit (p.
