SAFETY INSTRUCTIONS
WARNING
The unit and the accessories can contain small parts. Keep all of the equipment
out of the reach of small children. The mains adapter is the disconnect device
between the product and mains power. The mains socket outlet must be close
to the equipment and easily accessible.
AREAS WITH EXPLOSION RISK
Always turn off the unit when you are in an area where there is a risk of
explosion. Follow all signs and instructions. There is a risk of explosion in
places that include areas where you are normally requested to turn off your car
engine. In these areas, sparks can cause explosion or re which can lead to
personal injury or even death.
Turn off the unit at lling stations, and any other place that has fuel pumps and
auto repair facilities.
Follow the restrictions that apply to the use of radio equipment near places
where fuel is stored and sold, chemical factories and places where blasting is
in progress. Areas with risk for explosion are often – but not always – clearly
marked. This also applies to below decks on ships; the transport or storage
of chemicals; vehicles that use liquid fuel (such as propane or butane); areas
where the air contains chemicals or particles, such as grain, dust or metal
powder.
LI-ION BATTERY
This product contains a Li-ion battery. There is a risk of re and burns if the
battery pack is handled improperly.
WARNING
Danger of explosion if battery is incorrectly replaced. To reduce risk of re or
burns, do not disassemble, crush, puncture, short external contacts, expose
to temperature above 60° C (140° F), or dispose of in re or water. Recycle or
dispose of used batteries according to the local regulations or reference guide
supplied with your product.
PROTECT YOUR HEARING
WARNING
Excessive exposure to loud sounds can cause hearing damage.
Exposure to loud sounds while driving may distract your attention and
cause an accident.
Do not hold the device near your ear when the loudspeaker is in use.

CARE AND MAINTENANCE
Your unit is a technically advanced product and should be treated with the
greatest care. Negligence may void the warranty.

wet, you should immediately power off the unit.
• Do not use or keep the unit in dusty, dirty environments. The unit’s moving
parts and electronic components can be damaged.
• Do not keep the unit in warm places. High temperatures can reduce the
lifespan for electronic equipment, damage batteries and distort or melt certain
plastics.

temperature, condensation can form on the inside which can damage the
electronic circuits.
• Do not try to open the unit in any other way than that which is indicated here.
• Do not drop the unit. Do not knock or shake it either. If it is treated roughly the
circuits and precision mechanics can be broken.
• Do not use strong chemicals to clean the unit.
