User manual ROLAND ML-2

[. . . ] 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 the AC adaptor is connected while power is on, the power supply is drawn from the AC adaptor. [. . . ] Tuning the knob clockwise boosts the distortion effect. 6 Connections * Inserting a connecting plug into the INPUT jack turns on the power to the unit. * Raise the amp volume only after turning on the power to all connected devices. * The use of an AC adaptor is recommended as the unit's power consumption is relatively high. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. * If there is a batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted due to power blackout or power cord disconnection. When connection cables with resistors are used, the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable. * Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. * 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 CHECK indicator will become dim when battery power gets too low. Replace the battery as soon as possible. A NOTE About Placement BOSS Compact Pedals have a non-slip rubber pad attached to its bottom cover. Depending on the material and temperature of the surface on which you place the Compact Pedal, the rubber pad may discolor or mar the surface. You can place a piece of felt or cloth under the unit to prevent this from happening. If you do so, make sure the unit will not slip or move accidently during use. 7 Connections fig.

Normally, you should adjust the LEVEL knob so there's no difference in the volume when switching the effect on and off. 10 Changing the Battery When the indicator goes dim or no longer lights while the effect is on, it means that the battery is nearly dead and must be replaced. Replace the battery following the steps below. * The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use a battery, please use the alkaline type. fig. replace-battery. eps 1.
