Roland F-90 owner manual

•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, the power-supply cord, or the plug 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 “Information” page.

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

•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 on the AC adaptor cord 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 handle the AC adaptor or its plugs with

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

It should be handled carefully, all the while keeping it level. Make sure to have a firm grip, to protect yourself from injury and the instrument from damage.

•Check to make sure the screws securing the unit to the stand have not become loose. Fasten them again securely whenever you notice any loosening.

•Disconnect the power cord.

•Disconnect all cords coming from external devices.

•Remove the music stand.

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

•Whenever you suspect the possibility of lightning in your area, disconnect the AC adaptor from the outlet.

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

•Should you remove the caps and screws, make sure to put them in a safe place out of children’s reach, so there is no chance of them being swallowed accidentally.
