If the users ignore this symbol and handle the
device the wrong way, bodily injury and damage
to the equipment could result.
Please read through the following safety tips and
precautions to ensure hazard-free use of the H4n.
Power requirements
Since power consumption of this unit is fairly
high, we recommend the use of an AC adapter
whenever possible. In case you use batteries, use
either alkaline or nickel-metal hydride batteries.
[AC adapter operation]
• Make sure to use only an AC adapter, DC5 center
plus 1A (ZOOM AD 14).The use of other than the
specified type may damage the unit and pose a
safety hazard.
• Connect the AC adapter only to an AC outlet
that supplies the rated voltage required by the
adapter.
• When disconnecting the AC adapter from the AC
outlet, make sure grasp the adapter itself and
never pull at the cable.
• During lightning or when not using for an
extended period, disconnect the AC adapter
from the AC outlet.
[Battery operation]
• Use two conventional size AA-1.5 volt batteries.
• H4n cannot be used for recharging. Pay close
attention to the labeling of the batteries to make
sure you choose the correct ones.
• When not using for an extended period, remove
the batteries from the unit.
• If battery leakage has occurred, wipe the battery
compartment and battery terminals carefully to
remove all remnant of battery fluid.
• When using the unit, the battery compartment
cover should be closed.
Environment
To prevent unexpected troubles and malfunctions,
avoid using H4n in environment where it will be
exposed to:
• Extreme temperatures
• Heat sources such as radiators or stoves
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
Handling
• Never place any objects filled with liquids, such
as a vase, on the H4n since this can cause
electric shock.
• Never place naked flame sources, such as lighted
candles, on the H4n since this can cause fire.
• The H4n is a precision instrument. Do not exert
undue pressure on the keys and other controls.
Take care not to drop, bump, and do not subject
it to shock or excessive pressure, which can
cause serious troubles.
• Take care that no foreign objects (coins or pins
etc.) or liquids (water, alcoholic drinks and
juice)can enter the unit.
• Do not place the H4n speaker closer to other
precision instruments (watch and computer),
electronic medical instruments, or magnetic cards.
Connecting cables and input and output jacks
You should always turn off the power to the H4n and
all other equipment before connecting or disconnecting
any cables. Make sure to disconnect all a connection
cables and the power code before moving the H4n.
Alterations
Never open the case of the H4n or attempt to
modify the product in any way since this can result
in damage to the unit.
Volume
Do not use the H4n at a loud volume for a long
time since this can cause hearing impairment.
USAGE PRECAUTIONS
Electrical interference
For safety considerations, the H4n has been designed
to provide maximum protection against the emission of
electromagnetic radiation from inside the device, and
protection from external interference. However, the
equipment that is very susceptible to interference or that
emits powerful electromagnetic waves should not be placed
near the H4n, as the possibility of interference cannot be
ruled out entirely.
With any type of digital control device, the H4n included,
electromagnetic interference can cause malfunctioning
and can corrupt or destroy data. Care should be taken to
minimize the risk of damage.
Cleaning
Use a soft, dry cloth to clean the H4n. If necessary, slightly
moisten the cloth. Do not use abrasive cleanser, wax, or
solvents (such as paint thinner or cleaning alcohol), since
these may dull the finish or damage the surface.
Please keep this manual in a convenient
place for future reference.
