To prevent this, replace the battery a little earlier. • Be sure to keep the battery snapped by connector into the housing, when using AC adaptor, too. * Even if AC Adaptor cord comes out during performance, operation immediately changes to battery, causing no trouble in continued performance. • Power is switched on while a plug is put into input jack. When you do not use, keep the plug off the jack. AC ADAPTOR (OPTION) When you operate NF-1 from AC line, use AC Adaptor for NF-1. BOSS AC A 120 FOR 117V AC BOSS AC A-240 FOR 240V AC BOSS ACA-220 FOR 220V AC BEFORE USING NF-1 • When operating NF-1 from AC line, use BOSS AC Adaptor for NF-1. • Avoid using NF-1 at very dusty location or under high temperature or humidity conditions.

A CO OPERATING NF-1 1 After connecting all cords required, set all knobs on the panel as illustrated. 2 Tread the pedal to check battery. If check lamp lights, battery is live. * If lamp does not light, it means dead battery, replace it with a new battery. r CHFCK —I I _ Q .J SENS Tread pedal to set the unit in the state that sound is effected. Adjust SENS control to a proper level. Adjust DECAY control according to a long or short decay as desired. NAME AND FUNCTIONS The NF-1 is a new effector designed to cancel noise and hum from instruments. By adjusting decay time, unpleasant "break offs" can be entirely eliminated when playing. And since decay time is variable from 100ms to 1.6s, it can be used with virtually any instrument, from guitars to keyboards, for more versatility during recording. AC ADAPTOR JACK SENS OUTPUT JACK fOUTPUT INPUT f PEDAL Noise Gate NF-1 • CHECK LAMP DECAY INPUT JACK SCREW SENS The SENS (sensitivity) control can be set to compensate for strong and weak noise levels. If instrument noise is loud, turn it counterclockwise. If noise is low, turn it clockwise. (Illustration shows pickup for a guitar with DECAY set to MIN.) For strong noise level Sound "Break-off" point This control is used to adjust damping of the sound when the signal level becomes lower than the SENS setting. (Illustration shows functioning when setting is varied.) Level adjusted by SENS control Sound When DECAY control is ... ,volume g, xUmed completely counterclockwise * Set at the center position s Turned completely clockwise INPUT JACK Electric guitars and other instruments are connected to this jack. * Power is controlled by the input jack. When an instrument is connected the unit is turned on, and when an instrument is disconnected the unit is turned off. OUTPUT JACK This jack is used for connection to an amplifier. AC ADAPTOR JACK This jack allows the unit to be used with a BOSS AC Adaptor. PEDAL SWITCH This allows foot control of NORMAL/ EFFECT mode. (Due to the use of an electronic switch, click sound is not produced.) CHECK LAMP This allows you to monitor NORMAL/ EFFECT switch and battery check. When the lamp lights if the pedal is pressed, battery is charged. If not, it must be replaced. SCREW Loosen with a coin to open unit for battery replacement.
