This symbol indicates explanations about
dangerous matters. If users ignore this symbol
and handle the device the wrong way, bodily
injury and damage to the equipment could result.
Please observe the following safety tips and precautions to ensure
hazard-free use of the RT-223.
• Power requirements
Since power consumption of this unit is fairly high, we
recommend the use of an AC adapter whenever possible. When
powering the unit from batteries, use only alkaline types.
[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 at the cable.
• During lightning or when not using the unit for an extended
period, disconnect the AC adapter from the AC outlet.
[Battery operation]
• Use four conventional IEC R6 (size AA) batteries
(alkaline).
• The RT-223 cannot be used for recharging.
• Pay close attention to the labelling of the battery to make
sure you choose the correct type.
• When not using the unit for an extended period, remove the
batteries 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.
• Environment
To prevent the risk of fire, electric shock or malfunction, avoid
using your RT-223 in environments 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 objects filled with liquids, such as vases, on the
RT-223 since this can cause electric shock.
• Do not place naked flame sources, such as lighted candles,
on the RT-223 since this can cause fire.
The RT-223 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.
• Connecting cables and input and output jacks
You should always turn off the power to the RT-223 and all
other equipment before connecting or disconnecting any
cables. Also make sure to disconnect all connection cables and
the power cord before moving the RT-223.
• Alterations
Never open the case of the RT-223 or attempt to modify the
product in any way since this can result in damage to the unit.
• Volume
Do not use the RT-223 at a loud volume for a long time since
this can cause hearing impairment.
Usage Precautions
• Electrical interference
For safety considerations, the RT-223 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-223, as the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the RT-223 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-223. 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.
