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

Symbols of caution actions

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.

CAUTION

 

 

CAUTION

Indicates a potentially hazardous situation which, if mishandled,

could result in moderate or minor personal injury, and/or

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.
