Caution
The SR-F1B weighs approximately 37 kg. Confirm that the structure of installation place, and suspending wires or belts
are heavy-duty enough to support the total weight ofthe load before suspension. Secure to lock the fixing metals of the
suspending wire or belt to the speaker. TOA takes no responsibility for any accidents or injuries resulting from the fall
of the SR-F1B due to incorrect installation.
• As for the general suspending methods of the SR-F1 B, refer to the figures below.
Be sure to use two suspending wires or belts.
Fix them to the ceiling reinforcement
individually.
Even in case of oblique installation of the
speaker, be sure to use two suspending wires
or belts.
WARNING

SR-F1B SPEAKER STAND
This speaker stand is manufactured by König&Meyer GmbH(K&M) of Germany for use with TOA's SR-F1B speaker.
The speaker stand consists of two main sections:
Stand: Model 213
Bracket: Model 19582
USAGE (Refer to Fig. 1.)
Extending the Stand Legs.
1 . Loosen the tripod clamp screw and extend the tripod legs by
sliding the clamp ring down the length of the stand until the leg
stays are horizontal, then retighten the screw.
Mounting the Speaker.
2 . Attach the stand bracket to the base of the speaker using the
supplied mounting screws and washers. (Fig. 2).
3 . After ensuring that the bracket clamp screw is loose and not
protruding into the interior of the bracket, carefully place the
speaker on the stand by sliding the bracket over the end of the
stand.
4 . After positioning the speaker, tighten the bracket clamp screw.
Adjusting Stand Height.
5 . Loosen the height lock screw.
6 . Loosen the handle clamp screw, then fold out the crank handle
and retighten the screw.
7 . While holding down the lock button, adjust the speaker's height by
turning the crank handle. (Clockwise rotation raises the speaker.)
The handle cannot be turned without holding down the lock button.
After adjustment is completed, release the lock button and make sure
that the shaft is securely locked. (This can be checked by rotating the
handle slightly.)
8 . Retighten the height lock screw.
9 . Loosen the handle clamp screw, flip the handle back into its
foldaway position and retighten the handle clamp screw. Be sure
the handle is always folded up except when adjusting the height.
Removal After Use
10. After use, lower and detach the speaker, then collapse the stand
in the reverse order of the above procedure.
Speaker Mounting Screw Storage
After the stand bracket is detached from the speaker, the speaker
mounting screws can be inserted into the threaded holes of the stand
bracket for storage. (Fig. 3).
PRECAUTIONS
Only use the stand on flat, hard ground or floor surfaces.
Avoid installing the stand near narrow passages where passers by might trip over the tripod legs.
When using the stand outdoors, take care to avoid exposure to strong winds.
To reduce the chance of the stand toppling over, avoid extending the stand too high.
When there is potential for instability and the danger of a fall, be sure to secure the stand with guy wires or other
devices.

SAFETY PRECAUTIONS
Follow this instruction manual to obtain the optimum
results before use.
We also recommend you keep this instruction manual
handy for future reference.
Note that this manual may include safety precautions not
applied to your products.
INSTRUCTION MANUAL

Prohibition
WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Avoid installing or mounting the unit in unstable locations, such as on a rickety
table or a slanted surface. Doing so may result in the unit falling down and
causing personal injury and/or property damage.
Prohibition
Install the unit only in a location that can structurally support the weight of the
unit and the mounting bracket. Doing otherwise may result in the unit falling
down and causing personal injury and/or property damage.
Caution
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
Install the unit only in stable locations, and make appropriate arrangements to
prevent it from falling down or rolling cross the floor. If it falls down or moves,
this may cause personal injury and/or property damage.
Caution
When unpacking or moving a heavy unit, be sure to handle the unit with two or
more persons. Falling or dropping the unit may cause personal injury and/or
property damage.
Caution
Do not place heavy objects on the unit as this may cause it to fall or break which
may result in personal injury and/or property damage. In addition, the object
itself may fall off and cause injury and/or damage.
Do not stand or sit on, nor hang down from the unit as this may cause it to fall
down or drop, resulting in personal injury and/or property damage.
Do not operate the unit 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.
Avoid placing the unit in a doorway or other high traffic area as people may trip
on the equipment and cords, or be injured by falling objects.
