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

shown in the table at right (factory-preset to 330  
ohms). To change, set the rotary switch to the  
desired impedance using a screwdriver blade.

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.  
Cable feed slot  
Rear cover  
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.  
F Series speaker  
If required, the positioning of the cover's line feed  
slot can be easily reversed by snapping the cover on  
"upside down".  
Speaker cable  
Model F-160WP must be mounted with the line feed  
slot facing down.

8. LOGO BADGE REORIENTATION  
The speaker's front grille logo badge is attached with  
double-sided tape. To change its orientation, carefully peel the  
logo off the grille and stick it back on again in the same location  
in the desired orientation.

9. OUTDOOR USE (F-160WP ONLY)  
Model F-160WP can be permanently installed outdoors, and  
other F Series speakers cannot.  
Rear cover  
In the F-160WP, the rear cover prevents water from getting  
into the terminal section. When installing the F-160WP  
outdoors, make sure that the rear cover is mounted with the  
line feed slot facing down.  
Speaker cable  
The inside of the rear cover  
If using a thicker speaker cable that does not easily fit through  
the rear cover's cable guide, use a knife to cut out the rubber  
cable guide along the imprinted groove, as shown in the  
illustration at right.  
[Note]  
When mounting model F-160WP on the wall or under the  
eaves, be sure to use optional outdoor mounting brackets.  
Adjust the speaker installation angle and direction within the  
ranges shown in the figures below:

Model F-160WP features drip-proof construction. However, do not dash water over it when cleaning as this  
may cause damage to the speaker components.  
When installing the F-160WP outdoors in a snowy area, protect the speaker by preventing snow from piling  
up on it.
