GENERAL SAFETY INFORMATION
CUSTOM S.p.A. declines all responsibility for
accidents or damage to persons or property
occurring as a result of tampering, structural or
installations, environments not in keeping with
the equipment’s protection degree or with the
required temperature and humidity conditions,
failure to carry out maintenance and periodical
inspections and poor repair work.
Your attention is drawn to the following actions
that could compromise the characteristics of
the product:
To prevent possible hearing dam-
age, do not listen at high volume
levels for long periods.
• Read and retain the instructions which follow.
• When using your device, always comply
with the safety rules to protect users and the
environment.
• Follow all indications and instructions given

•
cessories such as power supplies unless
• When positioning the device, make sure
cables do not get damaged.
• Dropping it or letting it fall may cause damage.
• If the device requires a connection to the
power grid, make sure the power cable pro-
vided with the appliance, or that you intend to
use is suitable with the wall socket available
in the system.
• Before any type of work is done on the ma-
chine, disconnect the power supply.
• Take care the operating temperature range
of equipment and its ancillary components.
• Do not block the ventilation openings.
• Do not insert objects inside the device as
this could cause short-circuiting or damage
components that could jeopardize device
functioning.
• Do not carry out repairs on the device your-
self, except for the normal maintenance
operations given in the user manual.
• Never pour any liquid into openings. This
may cause electrical shock and damage the
device.
• Do not modify the device and its accessories
as power supply, cradles, etc.
• Periodically perform scheduled maintenance
on the device to avoid dirt build-up that could
compromise the correct, safe operation of

S.p.A.
• Do not leave this device in an uncontrolled
environment where the storage temperature
may damage the device.
DEVICE
• Keep your device and all accessories out of
the reach of children.
• Keep your device dry as liquids can corrode
the metal circuits. Keep your device away
from high temperatures because high tem-
peratures can reduce the life of electronic
components, melt plastics and damage the
battery.
• Do not attempt to open the device case or
disassemble the device.
• Unauthorized disassembly will potentially
damage the device.
• Always use the original accessories, other-
wise the warranty will be void and the safety
and the performance may be compromised.
POWER SUPPLY
• Use ONLY a CUSTOM S.p.A. approved
power supply. Use of alternative power supply
will invalidate any approvals given to this unit
and may be dangerous.
• Supplying the device with inappropriate volt-
age may cause harm to the battery or, even
worse, burn the device.
• If the device will not be used for a long time,
disconnect it from the power source to avoid
damage by transient overvoltage.
• For pluggable device, the socket outlet should
be near the device and should be easily ac-
cessible.

CAUTION: Risk of explosion if battery is re-
placed by an incorrect type. Dispose of batteries
according to instructions.
• Use only CUSTOM S.p.A. approved batteries.
• Never use the battery if it is damaged.
• CUSTOM S.p.A. approved rechargeable
battery packs are designed and constructed
to the highest standards within the industry.
However, there are limitations to how long
a battery can operate or be stored before
the actual life cycle of a battery pack, such
as heat, cold, harsh environmental conditions
and severe drops.
• When batteries are stored over six months,
some irreversible deterioration in overall bat-
tery quality may occur. Store batteries a half
of full charge in a dry, cool place, removed
from the equipment to prevent loss of capac-
ity, rusting of metallic parts and electrolyte
leakage. When storing batteries for one year
at least once a year and charged to half of
full charge.
• Charge the battery when the power level is
low. It is recommended that you use up the
entire battery charge before recharging, to
ensure longer battery life.
