– A place subject to high temperatures, such as under direct sunlight or lighting equipment, near a
heat source, or in a sauna
– Inside a vehicle with the windows closed (especially in summertime)
– A place exposed to hot air, such as from a hair dryer
• Place this unit on a flat, level surface. When placed on a sloped surface, the unit may fall over or
fall off the surface due to its own vibration, resulting in injuries, malfunctions, or performance
degradation.
• This unit is not anti-magnetic. Keep objects susceptible to magnetism (recorded tapes, watches, cash
cards and credit cards with magnetic coding, etc.) away from the unit. When you carry around the
unit, keep this in mind as well.
How to care for the unit
You can use the unit more comfortably and for a longer period of time by following the maintenance
procedure below.
• If the surface becomes dirty, wipe the surface using a soft, dry cloth or a cloth soaked in water or
lukewarm water and wrung well. Depending on the type of dirt, it may not be possible to remove it.
Note
• If the surface of the unit gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the
unit.
On BLUETOOTH® communications
• Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical
devices. Turn off this unit and other BLUETOOTH devices in the following locations, as it may cause an
accident:
– in hospitals, near priority seating in trains, locations where inflammable gas is present, near
automatic doors, or near fire alarms.
Other notes
• When placed in an extremely hot or cold environment, the unit stops battery charging for safety
reasons. When the battery is kept charging itself for an extended period of time, the unit may stop
battery charging as well. In such a case, make sure that the ambient temperature is within the
operating temperature range (5 °C - 35 °C (41 °F - 95 °F)), unplug and plug the AC power cord (mains
lead), and then charge the battery all over again.
• Even if you do not intend to use the unit for a long time, charge the battery to its full capacity once
every 6 months to maintain its performance.
• If your skin remains in contact with the handle for a long time while the light is turned on, there is
a risk of low-temperature burns. To carry a speaker while it is powered on, turn the light (lighting
function) off.
• Place the unit in a location with adequate ventilation to prevent heat buildup and prolong the life of
the unit.

• Should any solid object or liquid fall into the unit, unplug the unit and have it checked by qualified
personnel before operating it any further.
• Water resistant performance is improved by the flat top structure of the unit, but this is not
guaranteed for all the situations.
