[. . . ] q Also includes a "Tap Tempo" function that lets you set the RATE to the tempo at which the pedal is pressed. 3 Panel Description fig. 01 1. AC Adaptor Jack 12 Accepts 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. [. . . ] * The use of an AC adaptor is recommended as the unit's power consumption is relatively high. * Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off. * 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 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). 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 unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible. 9 Operating the Unit fig. 05 2.

Effect reflects knob positions Effect synchronized to tempo * If you carry out Step 3 immediately after Step 2 , Step 3 may inadvertently be interpreted as tempo input, thus changing the RATE setting. Allow a brief interval to pass before progressing from Step 2 to Step 3 . * If you adjust the RATE knob after completing the settings, the effect then reflects the position of the RATE knob.
