Installing Batteries
Batteries are supplied with the unit. The life of these batteries may be limited,
however, since their primary purpose was to enable testing.
Insert the included batteries as shown in figure, being careful to orient the batteries
correctly.
fig.02
• When turning the unit upside-down, get a bunch of newspapers or magazines, and
place them under the four corners or at both ends to prevent damage to the
buttons and controls. Also, you should try to orient the unit so no buttons or
controls get damaged.
• When turning the unit upside-down, handle with care to avoid dropping it, or
allowing it to fall or tip over.
• Make sure the “+” and “–” ends of the batteries are oriented correctly.
• When the batteries run down, the POWER indicator gets dim. If this happens,
replace with new batteries.
• When replacing the batteries, use six AA type.
• Avoid using new batteries together with used ones. In addition, avoid mixing
different types of batteries. Doing so can result in fluid leakage.
• Battery life can vary depending on battery type.
Continuous usage time under battery power is about 10 hours with
alkaline batteries and about 4 hours with carbon batteries. (This may
vary according to usage conditions.)

Making the Connections
• The use of an AC adaptor is recommended as the unit’s power consumption is
relatively high. Should you prefer to use batteries, please use the alkaline type.
• 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.
• Use a cable from Roland to make the connection. If using some other make of
connection cable, please note the following precautions.
• Some connection cables contain resistors. Do not use cables that incorporate
resistors for connecting to this unit. The use of such cables can cause the sound
level to be extremely low, or impossible to hear. For information on cable
specifications, contact the manufacturer of the cable.
• When the unit is running on battery power, the power comes on when you insert
the connector plug into the INPUT R (MONO) jack.
• 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).
• 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.
When powering up: Turn on the power to your guitar amp
When powering down: Turn off the power to your guitar amp
• 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.
• Turn on the power before you connect headphones. When turning off the power,
first unplug the headphones, then switch off the power.
• Please observe due caution when using headphones while the LEVEL switch is set
to +4 dBu, since their volume may get significantly higher.

Each press of the EFFECT ON/OFF pedal switches effects on or
off. When effects are off, the sound coming in through the INPUT
jack is output unchanged.
* When direct sound is set to OFF, no signal is output from the
OUTPUT jacks when the effects are off. When the effects are
turned on, only the effect sound is output.
The factory default setting for direct sound is ON.
