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 RT-123.
• Power requirements
The RT-123 is powered by the supplied AC adapter. To
prevent malfunction and safety hazards, do not use any
other kind of AC adapter.
When using the RT-123 in an area with a different line
voltage, please consult your local ZOOM distributor about
acquiring a proper AC adapter.
• Environment
Avoid using your RT-123 in environments where it will be
exposed to:
• Extreme temperature
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
• Handling
The RT-123 is a precision instrument. Do not exert undue
pressure on the keys and other controls. 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 RT-123 or attempt to modify the
product in any way since this can result in damage to the
unit.
• Connecting cables and input and output
jacks
You should always turn off the power to the RT-123 and all
other equipment before connecting or disconnecting any
cables. Also make sure to disconnect all cables and the AC
adapter before moving the RT-123.
Usage Precautions
• Electrical interference
For safety considerations, the RT-123 has been designed to
provide maximum protection against the emission of
electromagnetic radiation from inside the device, and protection
from external interference. However, equipment that is very
susceptible to interference or that emits powerful electromagnetic
waves should not be placed near the RT-123, as the possibility of
interference cannot be ruled out entirely.
With any type of digital control device, the RT-123 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 RT-123. 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.
