NF-CS1EXPANSION SET
READ ME FIRST
Thank you for purchasing TOA’s Expansion set.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct
and safe operation.
• Be sure to follow all the precautionary instructions in this section, which contain important
warnings and/or cautions regarding safety.
• After reading, keep this manual handy for future reference.
When Installing the Unit
• Do not expose the unit to rain or an
environment where it may be splashed
by water or other liquids, as doing so may
result in re or electric shock.
• Since the unit is designed for indoor use, do
not install it outdoors. If installed outdoors,
the aging of parts causes the unit to fall
off, resulting in personal injury. Also, when
it gets wet with rain, there is a danger of
electric shock.
• Avoid installing the Sub-Unit in locations
exposed to constant vibration.
Excessive vibration can cause the Sub-Unit
to fall, potentially resulting in personal injury.
When the Unit is in Use
• Should the following irregularity be found
during use, immediately switch off the
power, disconnect the power supply plug
from the AC outlet and contact your nearest
TOA dealer. Make no further attempt to
operate the unit in this condition as this may
cause re or electric shock.
· If you detect smoke or a strange smell
coming from the unit
· If water or any metallic object gets into the
unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged
(exposure of the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds)
• To prevent a re or electric shock, never
open nor remove the unit case as there
are high voltage components inside the
unit. Refer all servicing to qualied service
personnel.
• Do not place cups, bowls, or other containers
of liquid or metallic objects on top of the
unit. If they accidentally spill into the unit,
this may cause a re or electric shock.
Indicates a potentially hazardous situation
which, if mishandled, could result in death
or serious personal injury.
WARNING

2
• Do not insert nor drop metallic objects or
ammable materials in the ventilation slots
of the unit's cover, as this may result in re
or electric shock.
• Avoid positioning sensitive medical
equipment in close proximity to the Sub-Unit
magnets, as the magnets could adversely
affect the operation of such sensitive
medical equipment as pacemakers,
potentially leading to patients fainting.
Indicates a potentially hazardous situation
which, if mishandled, could result in
moderate or minor personal injury, and/or
property damage.
CAUTION
When Installing the Unit
• Avoid installing the unit in humid or dusty
locations, in locations exposed to the direct
sunlight, near the heaters, or in locations
generating sooty smoke or steam as doing
otherwise may result in re or electric shock.
• To avoid electric shocks, be sure to switch
off the unit's power when connecting
speakers.
When the Unit is in Use
• Do not operate the unit for an extended
period of time with the sound distorting.
Doing so may cause the connected
speakers to heat, resulting in a re.
• Do not connect headsets directly to the
Distributor.
If headsets are plugged into the Distributor,
output from the headsets may become
overly loud, potentially resulting in temporary
impairment of hearing.
• Avoid placing any magnetic media in
close proximity to the Sub-Unit magnets,
as this could have a harmful effect on the
recorded contents of magnetic cards or
other magnetic media, possibly resulting in
damaged or destroyed data.
The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall
be easily accessible.
Warning: Operation of this equipment in a residential environment could cause radio interference.
