Safety Precautions
Please observe the following safety tips and precautions to
ensure hazard-free use of the 2020.
• Power requirements
The 2020 is powered by the supplied AC adapter
AD0003/AD0004. Do not use any other kind of AC
adapter to prevent malfunction and safety hazards.
When wishing to use the 2020 in an area with a different
line voltage, please consult your local ZOOM distributor
about acquiring a proper AC adapter.
• Environment
Avoid using your 2020 in environments where it will be
exposed to:
• Temperature extremes
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
• Handling
Since the 2020 is a precision electronic device, avoid
applying excessive force to the switches and buttons. Also
take care not to drop the unit, and do not subject it to
shock or excessive pressure.
• Alterations
Never open the case of the 2020 or attempt to modify the
product in any way since this can result in damage.
• Connecting cables and input and output jacks
You should always turn off the power to the 2020 and all
other equipment before connecting or disconnecting any
cables. Also make sure to disconnect all cables and the
AC adapter before moving the 2020.
Usage Precautions
• Electrical interference
The 2020 uses digital circuitry that may cause interference
and noise if placed too close to other electrical equipment,
such as TV sets and radio receivers. If such problems
occur, move the 2020 further away from the affected
equipment. Also, when fluorescent lights or devices with
built-in motors are close to the 2020, the unit may not
function properly.
• Cleaning
Use a soft, dry cloth to clean the 2020. 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.
