PRECAUTIONARY

MEASURES

CAUTION:

READ CAREFULLY

BEFORE USING !

UFO.OD includes

magnetic products.

Do not place

ferromagnetic objects in

reach of the base and

carrier. Ferromagnetic

elements include iron,

nickel, cobalt, and any of

their alloys. Non-

ferromagnetic metals such

as aluminum, silver, gold, or

copper can safely be used

with the UFO.OD device.

The device should

not be used if

pregnant or ﬁtted

with a cardia pacemaker or

automatic internal

deﬁbrillators or insulin

pumps. Keep out of reach of

children. Keep out of reach

of magnetically stored data

such as computers, disks,

credit cards, magnetic keys,

etc.

A minimum distance of

10 cm (4 inches) is

recommended.

THE BASE

• The power adaptor

delivered with the unit

should preferably be

plugged against a

vertical wall, allowing

sufﬁcient air ﬂow. Do

not damage the power

cable.

• An optical sensor

(16mm diameter) is

located at the center of

the base. The optical

path to the sensor

must always be clear

of obstacle. The rest of

the base can be

covered by any non-

ferromagnetic material

(e.g a tablecloth).

• Keep the central

optical sensor clean.

Avoid pointing bright

lights towards the

central optical sensor.

THE CARRIER

• A reﬂective spot (5mm

diameter) is located at

the center of the

carrier's lower side.

The optical path to this

sensor must always be

clear of obstacle. The

rest of the carrier can

be covered or

embedded in any non-

ferromagnetic material.

Keep the reﬂective

spot clean.

• Do not place the

carrier on a metallic

surface (e.g metallic

table), as it would stick

to it.

• Do not place loads

made of ferromagnetic

material or their alloys.

• The levitation height

depends on the load.

Table 1 gives indicative

values of levitation

height vs load weight.

• Stability depends on:

‣ the weight of the

load: the heavier

the less stable.

The maximum

recommended

load is 850g.

‣ the shape of the

load: the more

compact the

more stable.

‣ the center of

gravity of the

load: the lower

the more stable.

‣ the centering of

the load: the

center of gravity

must be perfectly

centered to avoid

irregular and

unstable rotation

of the carrier.

TEMPERATURES

The temperatures given in

Table 2 are indicative and

apply only for the naked

base placed on an horizontal

surface. Characteristics may

differ when the base is

embedded. To prevent

overheating, the base is

thermally protected and will

shutdown automatically

when reaching 50℃.

PLACING THE

CARRIER IN

EQUILIBRIUM

Placing the carrier in

equilibrium might be

challenging at ﬁrst, but will

become extremely easy after

a some practice.

1. Place the base on a

clean and dry horizontal

non-ferromagnetic

surface, keeping the

carrier out of reach of the

base.

2. Sit comfortably in front of

the base. Hold the carrier

ﬁrmly between your

thumb and index at

~25cm (~1 foot) above

the center of the base.

3. Lower down the carrier

fairly rapidly keeping it

level and centered, until

you feel a light upward

resistance. This is the

ﬂoating height.

4. The next step requires

some practice. Move the

carrier around until you

notice that the base take

the control of the carrier

and release it smoothly.

MAINTENANCE

• Never open the device or

its power supply.

• Unplug the power supply

after each use.

• The magnetic products

present in the device are

sensitive to heat. Never

expose any part to heat

greater than 40℃ (104℉).

• Wash the carrier and base

while unplugged with a

wet tissue and a mild

cleaning agent. Dry

immediately with a dry

tissue. Do not use hot

water or hot air dryer. Do

not submerge the base in

any liquids and do not

expose to large liquid spill

or liquid amounts.

• If you do not plan to use

the device over a long

period of time, remove the

power cable, place the

device, the carrier, and the
