1. 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 are used in this manual to prevent bodily injury and property damage which
could result from mishandling. The conventions of the symbols and messages are described below. Before
doing anything else, read this manual first so you are thoroughly aware of the potential safety hazards as well as understand the safety symbols and messages. Then before operating your product, read through the instruction manual so you are familiar with its general operation.

Symbols of prohibited actions |
CAUTION |
PROHIBITION |
Indicates a potentially hazardous situation which, if mishandled, WARNING could result in death or serious personal injury.
When Installing the Unit
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 speaker falling down and |
|
|
causing personal injury and/or property damage. |

property damage. |
|
|
When the Unit is in Use |
|
|
Do not stand or sit on a speaker as this may cause it to fall down or drop, resulting in |
|
|
personal injury and/or property damage. |
|
|
|
|
PROHIBITION |
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. HANDLING PRECAUTIONS
Use optional mounting brackets when mounting the speaker to the ceiling or wall.
Avoid using the speaker on the beach because the speaker's life can be greatly shortened by sea breezes.
TOA takes no responsibility for any accident or equipment failure due to inadequate installation places or incorrect installation methods or disassembly or modifications carried out for the purposes other than repair
service.
The F series speaker is not magnetically shielded. Install it as far away as possible from color televisions or
video monitors to avoid degradation in television picture quality.
4. FEATURES
Two-way bass-reflex system.
High efficiency, wide range, and high input power handling capacity.
F-160 series: High power capacity 13 cm woofer with a large 90 mm magnetic circuit, and high-efficiency
3 cm dome tweeter with a large 70 mm magnetic circuit.
F-240 series: High power capacity 16 cm woofer with a large 90 mm magnetic circuit, and high efficiency 3 cm dome tweeter with a large 70 mm magnetic circuit and a titanium diaphragm.
The tweeter employs a constant directivity horn which ensures uniform sound dispersion of 90 ° horizontal and 90° vertical.
Independent built-in overload protection circuitry for woofer and tweeter. (Low-impedance models only) A detachable rear cover cleanly conceals the speaker terminals.
Acoustically efficient polypropylene enclosure.
Optional wall and ceiling mounting brackets.
F-160WP: Drip-proof construction makes the speaker system ideal for outdoor use.
5. OVERLOAD PROTECTION CIRCUITRY INFORMATION
(LOW-IMPEDANCE MODELS ONLY)
The F-160G, F-160W, F-240G, and F-240W have a built-in overload protection circuitry.
If the excessive input is applied to a woofer or tweeter, the overload protection circuitry is activated and cuts off the signal supply to the speaker component.
A sudden drop of the volume level of either the high or low frequencies during speaker operation indicates that the overload protection circuitry has been activated. In such a case, reduce the amplifier volume and just
wait. The protection circuitry is automatically reset after approximately 3-30 seconds. After the circuitry is reset, set the volume at a lower level than before.
[Important Note]
This overload protection circuitry does not perfectly protect the speaker component. Depending upon the
excessive input to be applied, the protection circuitry may not operate, causing damage to the speaker component. In addition, the circuitry may not be restored to the previous state if the excessive input is applied
continuously for long time. Take special care that the excessive input is not applied to the speaker during use.

6. IMPEDANCE CHANGE (HIGH-IMPEDANCE MODELS ONLY)
Because the following models have a built-in matching transformer, connect them to the amplifier with a
high-impedance (70 or 100) line output.
F-160GM, F-160WM, F-160WP, F-240GM and F-240WM
Input impedance can be switched in five steps, as |

When using the 100 line, never set the impedance to 170 ohms. The speaker itself or the power amplifier may be damaged.
7. REAR COVER USAGE
F Series speakers feature a rear cover that cleanly
conceals the speaker terminals on the rear panel.
To remove the cover, insert a finger in the line feed slot and pull the cover away from the speaker. To reattach, simply snap the cover back into place.
If required, the positioning of the cover's line feed slot can be easily reversed by snapping the cover on
"upside down".
Model F-160WP must be mounted with the line feed
slot facing down.
