The symbol alerts the user to things that must be carried out. The specific thing that must be done is indicated by the design contained within the circle. In the case of the symbol at left, it means that the powercord plug must be unplugged from the outlet.

• Be sure to use only the AC adaptor supplied with the unit. Also, 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.

..................................................................................................

Do not excessively twist or bend the power cord, nor place heavy objects on it. Doing so can damage the cord, producing severed elements and short circuits. Damaged cords

are fire and shock hazards!

..................................................................................................

Do not allow any objects (e.g., flammable material, coins, pins); or liquids of any kind (water, soft drinks, etc.) to penetrate the unit.

..................................................................................................

Immediately turn the power off, remove the AC adaptor from the outlet, and request servicing by your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page when:

The AC adaptor or the power-supply cord has been damaged; or

Objects have fallen into, or liquid has been spilled onto the unit; or

The unit has been exposed to rain (or otherwise has become wet); or

The unit does not appear to operate normally or exhibits a marked change in

performance.

..................................................................................................

In households with small children, an adult should provide supervision until the child is capable of following all the rules

essential for the safe operation of the unit.

..................................................................................................

• Protect the unit from strong impact. (Do not drop it!)

..................................................................................................

Do not force the unit’s power-supply cord to share an outlet with an unreasonable number of other devices. Be especially careful when using extension cords—the total power used by all devices you have connected to the extension cord’s outlet must never exceed the power rating (watts/amperes) for the extension cord. Excessive loads can cause the insulation on the cord to heat up and eventually melt

through.

..................................................................................................

Before using the unit in a foreign country, consult with your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Infor-

mation” page.

..................................................................................................

Batteries must never be recharged, heated, taken apart, or thrown into fire or water.

..................................................................................................

The unit and the AC adaptor should be located so their location or position does

not interfere with their proper ventilation.

..................................................................................................

Always grasp only the plug or the body of the AC adaptor when plugging into, or

unplugging from, an outlet or this unit.

..................................................................................................

Whenever the unit is to remain unused for an extended period of time, disconnect the

AC adaptor.

..................................................................................................

Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed so they are out of

the reach of children.

..................................................................................................

Never climb on top of, nor place heavy objects on the unit.

..................................................................................................

• Never handle the AC adaptor body, or its

plugs, with wet hands when plugging into, or unplugging from, an outlet or this unit.

..................................................................................................

Before moving the unit, disconnect the AC adaptor and all cords coming from external

devices.

..................................................................................................

Before cleaning the unit, turn off the power and unplug the AC adaptor from the outlet

(p. 7).

..................................................................................................

Whenever you suspect the possibility of lightning in your area, disconnect the AC

adaptor from the outlet.

..................................................................................................

If used improperly, batteries may explode or leak and cause damage or injury. In the interest of safety, please read and observe the following precautions (p. 14).

Carefully follow the installation instructions for batteries, and make sure you observe the correct polarity.

Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries.

Remove the batteries whenever the unit is to remain unused for an extended period of time.

If a battery has leaked, use a soft piece of cloth or paper towel to wipe all remnants of the discharge from the battery compartment. Then install new batteries. To avoid inflammation of the skin, make sure that none of the battery discharge gets onto your hands or skin. Exercise the utmost caution so that none of the discharge gets near your eyes. Immediately rinse the affected area with running water if any of the discharge has entered the eyes.

Never keep batteries together with metallic objects such as ballpoint pens,

necklaces, hairpins, etc.

..................................................................................................

Used batteries must be disposed of in compliance with whatever regulations for their safe disposal that may be observed in

the region in which you live.

IMPORTANT NOTES

In addition to the items listed under “USING THE UNIT SAFELY” on page 2, please read and observe the following:

Power Supply:

Use of Batteries

Do not use this unit on the same power circuit with any device that will generate line noise (such as an electric motor or variable lighting system).

The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.

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.

When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected.

This way, you can prevent malfunction and/ or damage to speakers or other devices.

Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices.

Placement

Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference.

This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.

To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture.

Maintenance

For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth.

Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Additional Precautions

Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.

Never strike or apply strong pressure to the display.

When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable’s internal elements.

To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).

When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.

Use only the specified expression pedal (EV- 5; sold separately). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.
