[. . . ] 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. * If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection). * As soon as you connect the AC adaptor, the unit is turned on. 3 4 5 6 4 Panel Description 2.

By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. When powering up: Turn on the power to your guitar amp last. When powering down: Turn off the power to your guitar amp first. * Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction. * When operating on battery power only, the unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible. 8 Operating the Unit fig. 05 3.
