2. SAFETY PRECAUTIONS
Be sure to read the instructions in this section
carefully before use.
Make sure to observe the instructions in this
manual as the conventions of safety symbols and
messages regarded as very important precautions
are included.
We also recommend you keep this instruction
manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are
used in this manual to prevent bodily injury and
property damage which could result from
mishandling. Before operating your product, read this
manual first so you are thoroughly aware of the
potential safety hazards as well as understand the
safety symbols and messages.
WARNING
Install the unit only in a location that can
structurally support the weight of the unit.
Doing otherwise may result in the unit falling down
and causing personal injury and/or property
damage.
To prevent personal injuries due to the fall of the
speaker, be sure to fix the speaker by means of
four stoppers and connect a safety wire.
CAUTION
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 fire or
electric shock.
Do not operate the speaker for an extended period
of time with the sound distorting. This is an
indication of a malfunction, which in turn can cause
heat to generate and result in a fire.
3. Impedance Switching (F-101CM and F-121CM)
The input impedance of the F-101CM and F-121CM is factory-preset to 3.3
(3 W for 100 line).
When changing the impedance, first confirm whether the speaker line is 70 V or 100 V line. Then disconnect
the red lead wire connected to the current transformer tap, and reconnect it to the desired tap.
[Precaution]
When using a 100 V speaker line, do not connect to the "250 " tap as the speaker or power amplifier may
fail.
4. Installation
1. Make a 218 mm diameter mounting hole in the ceiling
using the supplied template (paper pattern).
2. Wrap the safety wire attached to the speaker around a
strong ceiling beam and secure by snapping the wire
endpiece onto the wire.
3. Connect the speaker cable to the push-in terminal.
Note
Change the impedance of the F-101CM or F-121CM at
this stage as required, because the change cannot be
made once the speaker has been installed.

hazardous situation which, if mishandled, could
result in death or serious personal injury.
