INSTRUCTIONS
This compact flanger is equipped with four con-
trols for a more versatile range of flanging effects.
These controls allows independent selection of
manual (delay time), depth, rate and resonance.
A new, low-voltage BBD provides more stable
operation, while special provisions have been
made to reduce noise and improve sound quality.

BEFORE USING THE BF-2
e When operating the BF-2 from the AC line, use the BOSS AC Adaptor. o
e Avoid using the BF-2 in very dusty locations or under high temperature or humidity
conditions.
e The battery (one Dry Battery, 9V) will last for 5 to 20 hours (manganese) or 15 to 40
hours (alkaline), depending on the conditions. The use of a BOSS ACA-Adaptor and
alkaline battery is recommended for a longer time performance,

The BOSS AC Adaptor is connected to the
Battery Eliminator jack when battery
operation is not necessarily the most desir-
able situation.
INDICATOR
By the LED indicator you can see whether
the unit is on or off, even in the darkest
On-stage situation. This indicator also allows
you to check the battery. When the time
comes to replace the battery, the indicator
fails to light or becomes dimmer.
PEDAL SWITCH
In our unique FET switching system there
are no mechanical contacts in the signal
system so it won't make an audible click,
and it can’t make a pop. The switching
totally electronically and therefore, cleanly.
THUMB SCREW
The battery sits in a special compartment
under the same footswitch plate that
activates the silent switch. When the time
comes to replace the battery, you don't
even need tools.
*Do not remove off the screw from the
unit.
OPERATING
THE
BF-2
MANUAL DEPTH RATE \ RES. _
After connecting all required cords, set
all knobs on the panel as illustrated.
Depress the pedal switch. Check lamp lights
to indicate “EFFECT ON” and extinguishes
to indicate “EFFECT OFF”,
*This check lamp is also used to check
battery. If lamp fails to light or becomes
dim, the battery should be replaced.
Once the rate control is set, other controls
can be varied as desired.
*When depth control is turned completely
clockwise, the manual control becomes
inoperative.

BATTERY REPLACEMENT AND PRECAUTIONS
BATTERY REPLACEMENT USE 9V BATTERY
e Loosen the screw and open the Pedal.
e Take out the battery from the Battery Housing and pull up the Battery Strap.
e Replace with a new battery.
e Put the Coil Spring to the Spring Base and close the Pedal.
e Firmly tighten the screw.,
* Make sure that the Battery Strap is not caught in the Pedal or Coil Spring.
