USAGE AND SAFETY PRECAUTIONS
In this manual, symbols are used to highlight warnings and
cautions for you to read so that accidents can be prevented. The
meanings of these symbols are as follows:
Please observe the following safety tips and precautions to ensure
hazard-free use of the 504.
Since power consumption of this unit is fairly high, we
recommend the use of an AC adapter whenever possible.
When powering the unit from a battery, use only an alkaline
type.
AC adapter operation
• Be sure to use only an AC adapter which supplies 9 V DC,
300 mA and is equipped with a "center minus" plug (Zoom
AD-0006). The use of an adapter 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,
always grasp the adapter itself and do not pull the cable.
• If the unit is not to be used for a long time, disconnect the AC
adapter from the outlet.
Battery operation
• Use only a 9 V (alkaline) battery (6LR61).
• The 504 cannot be used for recharging.
Pay close attention to the labelling of the battery to make sure
you choose the correct type.
• If the 504 is not to be used for an extended period of time,
remove the battery from the unit.
• If battery leakage has occurred, wipe the battery compartment
and the battery terminals carefully to remove all remnants of
battery fluid.
• While using the unit, the battery compartment cover should
be closed.
Avoid using your 504 in environments where it will be
exposed to:
• Extreme temperature
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
• The 504 is a precision instrument. Except for the foot
switches, do not push other parts with your feet or subject
them to strong force.
• Take care that no foreign objects (coins or pins etc.) or liquids
enter the unit.
• Be sure to turn the power to all equipment off before making
connections.
• Before moving the unit, turn the power off and disconnect all
cables and the AC adapter.
Never open the case of the 504 or attempt to modify the
product in any way since this can result in damage to the unit.
Usage precautions
For safety considerations, the 504 has been designed to provide
maximum protection against the emission of electromagnetic
radiation from inside the device, and from external
interference.However, equipment that is very susceptible to
interference or that emits powerful electromagnetic waves
should not be placed near the 504, as the possibility of
interference cannot be ruled out entirely.
Whatever the type of digital control device, the 504 included,
electromagnetic damage can cause malfunctioning and corrupt
or destroy data. Since this is an ever-present danger, thorough
care should be taken to minimize the risk of damage.
Use a soft, dry cloth to clean the 504. 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.
Connecting cables and input and output jacks
You should always turn off the power to the 504 and all other
equipment before connecting or disconnecting any cables. Also
make sure to disconnect all cables and the AC adapter before
moving the 504.
