FOREWORD
Our congratulations on the decision to invest in high quality F1 patient chair. We wish that your
work with it will be enjoyable and problem free.
Fimet F1 chair is electrically controlled, multi-functional patient treatment chair for medical
purposes. Because of its flexibility, it can be used not only as a Dental chair but can be modified to
be used also as an ENT, Ophthalmology and Podiatry patient chair. It can be used as well for barber
and cosmetology applications.
This well-designed chair is also easy to use. For example the armrest can swing out, so it is easy to
get into the chair, and thereby make it easier for elder or invalid patients. Because the whole chair
top can be rotated, it is also easy to use it in a small room.
The chair is controlled by remote foot-or hand control. In some applications two fixed joystick type
foot controls are also available. The microprocessor inside of the chair is controlling the chair and
performing self diagnose of itself constantly. It is possible to store eight working positions in the
chair’s memory. The whole control system as well as the motors run on 24 volts, which makes the
chair absolute safe for both patient and the doctor
It is possible to select from various color possibilities; an appropriate combination that suits the
room colors. The chair’s upholstery has been designed to minimize the amount of seams and
thereby maximize hygiene. The upholstery can be of polyurethane, vinyl or genuine leather. The
upholstery is easy to clean and, if necessary, replace.

PRODUCT DESCRIPTION
CONSTRUCTION
The chassis and foundation of the F1 chair are made of a sturdy steel construction. The geometry of
the up-and down mechanism has an ingenious compact design that offers the chair outstanding
flexibility. From its lowest point 35 cm ( 14 inches) the chair moves almost linearly to 91 cm ( 36
inches). All bearing are pre-lubricated and will last almost indefinitely without maintenance. All
visible parts are made of composite materials by using the RIM technique ( Reaction Injection
Molding). The seat, backrest and other force absorbing parts are reinforced.
MOTORS AND ELECTRONICS
The two motors and the electric circuitry of the F1 chair are of low voltage type that reduces the risk
of electrical shock and hazard to a minimum. Steel and composite materials in combination are
used in the gears of the drive mechanism. A configuration that gives the chair a smooth and quiet
ride and a long lifetime of the mechanism. The electronics, including the microprocessors for the
programming functions are concentrated on one circuit board that are conveniently located on the
right hand side of chair. All major components of the F1 chair are easily accessible for fast and
convenient service and maintenance.
All functions of the F1 chair are controlled by means of a cordless foot control that meet the
individual needs of convenience.

OWNERS MANUAL 11
SAFETY FEATURES
A safety switch is located on the printed circuit board on the right side under the chair. If something
(e.g. a foot) come in between the lifting mechanism and the base of the chair when the chair is in
motion, this safety switch will immediately stop all movements. The chair can be restarted as soon
as whatever caused the stop has been removed. For improved safety the foot control also works as
an emergency stop switch. Hit any of the control switches of the foot control when the chair is in
motion and all movements of the chair stops immediately.
Activate any button for emergency stop
CONTROLLING THE CHAIR
FNOTE! If some other device is disturbing wireless remote control transmission, immediately
start using remote controls with recharge cable.
FOOT CONTROL
All movements of the F1 chair are controlled by means of the cordless foot control. The foot
control contains all functions for the manual operation of the chair. It can be used also for
controlling F1 unit options. In addition, the foot control is used for programming and activating
different pre-set working positions. Transmission of the electro-magnetic signals between the foot
control and the chair is accomplished by means of inductive fields. In cases when you have more
than one F1 chair in your office the foot controls have different codes in order to prevent any
interference.
The foot control is operated by rechargeable accus size AA. To charge the accus just connect the
foot control to the cord that is provided with the chair. In the event of malfunction in the cordless
transmission, connect the cord used for charging the accus to the foot control. This will override
the cordless transmission, and the chair can now be operated as usual. Do not use normal
batteries instead of accus in the foot control!
FHint: If accus have exhausted, the chair can be operated as normally with recharge cable.

Backrest up: ⇒Lever right
Memory recall ⇒Button 2 + some other function
In the right and left sides of the foot control lies two buttons; in the
edge and on the top. These buttons are connected parallel so the same
function is performed from both buttons.
RECHARGING FOOT CONTROL BATTERIES
The foot control contains four rechargeable 1.2 V accus (Ni-Cd) for operation of the cordless
transmission. Recharging time is about 24 hours. Typically recharging must be performed
three to six week intervals. If there is also F1 E unit attached, the need of recharge is
increased. When the display on the back of the chair indicates A, it means the accus need to
be recharged. If the chair is operated during recharging process the recharge time is longer.
∇WARNING! Do not replace the rechargeable accus delivered with the chair with any
other type of batteries. Always use genuine batteries provided by Fimet
Oy or exactly same Ni-Cd type AA. Using non rechargeable batteries you
are exposed to danger!
RECHARGING:
oConnect the other end of the recharge cable to the bottom of the foot control and other end to
front of the chairs base. Refer to the picture on page 6.
oThe batteries will now automatically recharge.
When the batteries are recharged, disconnect the recharge cable.

OWNERS MANUAL 13
HAND CONTROL
The hand control does not need to be pointed towards the chair like for example tv:s remote
control because hand control works with different principle. The range is about 2 m and it works
best when held in horisontal position in hand.
Hand control has same kind of coding system like foot control. When the chair is controlled with
both hand and footcontrol, they must possess the same coding.
RECHARGING HAND CONTROL BATTERIES
Connect the provided recharging cable in to the connector located in the other end of the hand
control and the other end to the recharge connector located back at the chairs base part.
Some chairs have separate holder for the hand control which has recharging function built-in.

OWNERS MANUAL 17
ERROR CODES AND MESSAGES OF SELF
DIAGNOSTIC PROGRAM
When the microprocessor of a F1 chair detects a fault it tries to inform about the most probable
reason. The error code is showed on the display of the chairs rear panel.
Starting from program version 6A.8B the program version is showed on the display when power to
the chair is switched on. This information can also be helpful when trying to find reason for a
problem.
In error codes there are two numbers (shown after each other) and the numbers are showed twice.
Error codes which start with number 1 are for lifting motor, 2 is for backrest motor and error codes
starting with 5 are for potentiometers.
It must be noticed, that no matter what error code is shown, the reason might be elsewhere.
Example: Fault code 50. A wire to the potentiometer of the lifting motor is broken or the
potentiometer is defective. The problem might be on the main pc-board, wires, on a terminal
connector, connector between the wires and pc-board, connector between the wires and
potentiometer or the potentiometer.
In case several problems occur at the same time the processor informs about the problem, which has
lowest number, for example when the voltage is low, the showed error code is 10 (not 20).
Error codes
10, 20: Low voltage (or missing) for motors
12: A wire to the lifting motor is broken
13: Wires to the lifting motor are shorted
22: A wire to the backrest motor is broken
23: Wires to the backrest motor are shorted
50,51: A wire to the potentiometer of the lifting motor is broken or the potentiometer is defective.
52,53: A wire to the potentiometer of the backrest motor is broken or the potentiometer is defective.
If the potentiometers are mechanically turned to its maximum or minimum values, these
same codes are displayed.
54,55: Lift (54), backrest (55): Movement limits too near each other or too near mechanical limit
{from ver. 6A8B6}
56,57: Lift (56), backrest (57): Some unlogic in the limits (e.g. upper limit < lower limit) {from ver.
6A8B6}
11, 14, 15, 16, 21, 24, 25, 26: Main printed circuit board is defective.
E, EE: (EEPROM) EEPROM is defective. Error message E is shown also when a position is tried to
be stored on channel 1 ( backrest down).
U: (Unit) Unit-adapter is connected to the chair, but the main processor can't get any reply from
the unit. Same error message comes, if instrument is picked up before turning power on.
Notice, that after "U"-error, the unit can't be used. Before power is switched OFF or safety -
switch is shortly activated.

OWNERS MANUAL 18
H: (Hot) Motor is too hot. Analog memory is charged with voltage which is proportional to the
current motors are using. When the current is too high too long time it is supposed that
motors are too hot and to prevent motors to be destroyed the current is turned off.
8: (All leds are on) Processor is in reset -state.
0: Blinking (Zero) Safety switch is pressed. This is actually no Error-code, but means, that
microcontroller is not working correctly. At the same time buzzer is usually on.
A: (Accumulator) when charge of accus is decreased to a low level (and foot control is on)
display is showing "A" (this "A" may sometimes occur also when noise is partly destroying
the signal so that microcontroller "misunderstands" battery information).
Messages why movement is stopped
If chairs movement is stopped before the chair has reached wanted position, to the display comes
the reason for the stop. Always when motor is stopping there comes a code of the reason for the
stop. If the movement was all right the code is not showed. One thing to notice is that if noise is
disturbing foot controllers signal, microcontrol can't say if command was interrupted or not. So
there will be not any code to show, though movement stop was not natural.
Messages when driving manually
When driving a chair manually only one motor at a time is moving. Used codes for exceptional
stops of movements are as follows:
5: Software current limit microprocessor stops supply of current to the motor
6: Hardware current limit electronics stops supply of current to the motor
7: Lower limit, the chair has reach the minimum level (soft limit)
8. Upper limit; the chair has reach the maximum level (soft limit)
9: No movement; the value of potentiometer doesn't change (automatic)
Messages when driving automatically
If one or both movements are stopped exceptionally, so that the chair doesn't
reach the programmed position, the reason for that is showed in following
formula: 1X2Y: where X and Y are replaced by a reason code 5 -9. If there is no
problem the code is 0.
Example: into the display comes following code 1025.
This means, that lifting motor has reached the programmed position (1 for lifting motor, 0 for OK),
but backrest motor has been stopped by the processor, because the current was too high (2 for
backrest motor, 5 for software current limit downwards). Reason for the error could be a mechanical
obstacle under the backrest.
If the automatic movement is stopped by a new command, code F comes to the display.

OWNERS MANUAL 19
ADDITIONAL INFORMATION
CHANGING THE MOVEMENT LIMITS
GChanging of the movement limits must left to be made by authorized service personnel. Do not
never drive the lift motor to the mechanical limits because the transmission may be damaged.
Shall be made if new limits of movements
are needed or in case of changing the
potentiometer or the pc-board, if the old
EEPROM has not been changed from the
old pc-board to the new one.
Programming goes as follows:
1. If possible, move chair and backrest to their approx. middle positions.
2. Short-circuit 6-pin connector (all pins together) at the chair-pc-board just next to the processor
circuit (special short-circuit piece available). If there is also Fimet F1 E unit attached to the chair,
the other flat cable must first be detached.
3. Press the PROG -switch and keep it down
4. Activate security switch at the bottom edge of the pcb-board and release it. (keep PROG still
pressed))
5. Press any switch at the foot control. Now Beep, Beep, Beep sound should be heard. Release
PROG -switch and foot control.
6. Chair goes now downwards (it can only be stopped at the security switch or at the mains
switch).
7. Press the USER -switch at the desired lowest limit. Now the chair start going upwards.
