3 Safety instructions
Please adhere to the legal guidelines for accident preventions and take note of the following
safety instructions.
Set up and Installation:
7/23
The Refraction Unit must not be installed or used in damp rooms.
Please ensure the refraction unit is mounted on a level and stable surface.
The power must correlate to that shown on the Type label.
The maximum carrying capacity of the translation table (6) is 40 kg, 25 kg maximum can be placed in
position 1 of the translation table.
To Operate:
Do not expose the system to any temperature extremes. The recommended usage temperature lies
between + 10° and + 40° C.
Avoid dripping water and water spray.
The maximum carrying capacity of the patient chair (5) is 170 kg. This must not be exceeded.
When the translation table (6) and the contact lens fitting table (7) are swung into position. There is a
scissor movement. This presents a risk of trapping!
The elevation column of the patient chair is not designed for continuous use. After continuous use for 60
seconds a cooling off period of 9 minutes must be adhered to.
Please note that neither the translation table (6) nor the contact lens fitting (7) should be allowed to hit
the patient` legs.
Do not exert any unnecessary pressure on the contact lens table (e.g. Leaning with the hand).
Ensure that the phoropter arm (2) does not hit the patient (e.g. as the chair moves upwards).
Longer use of the examination lamp (3) can lead to a heating of the lamp housing. There is a danger of
burning.
Other:
Do not pull the cable when removing the plug from the socket.
Position the cable so that there is no risk of walking on it or falling over it. Any other risk of damage to the
cable must be avoided (e.g. sharp edges or strong heat).
The plug must be removed from the socket before carrying out repairs, maintenance or commissioning.

5.3 Description and function of the components
Please ensure that the refraction unit is connected to the power supply with the intended
power cable.
5.3.1 Translation table
The translation table serves to carry ophthalmic instruments such as slit lamps and
ophthalmometers. These instruments can be moved using the table into position 1 and
position 2.
Power Supply for the table top devices
Power is supplied to the table top devices via the connection ports in the translation table. To
configure / change the power supply please contact the bon Optic qualified personnel.
More detailed information on power supply can be found in chapter 8: Technical Data.
Power will be supplied automatically to the table top device on switching into working position
1 or 2. The translation table ensures a via a potentiometer the smooth introduction of power
(for e.g. the brightness adjustment on the slit lamp).
Operation
1) Swing the translation table into the required position.
2) Lock the table in position.
3) Slide the table into the required working position 1 or 2.
4) In order to swing back out of the way unlock the table.
When the refraction unit is switched off the table lock retains it’s status from prior to switch
off. That means that after switching on the refraction unit again, the table lock is activated if
the table lock was in the on position when the refraction unit was last switched off.
Fig. 5-2: Switch for locking the table
Try not to be forceful when activating/deactivating the table lock!

5 Operation bon E-20 SE
5.3.2 Patient chair
The height adjustment (Up and down movement) of the patient chair is activated via a switch
on the control console. (see illustration. 5.1). When the contact lens table is swung out of the
rest position the chair movement will be automatically deactivated. Thus preventing the
patient from colliding with the table and any resulting damage to the refraction unit.
5.3.3 Phoropter arm
In order to move the phoropter from the rest position, as the user pull the phoropter arm back
on itself (shown in illustration 5-3, Pos.1). Turn the lower part of the arm towards the patient
(illustration 5-3, Pos. 2).
Operate in reverse in order to move the phoropter back into the rest position.
11/23
Position 1: Rest position Position 2: Phoropter arm angled Position 3: Phoropter arm in

Fig. 5-3: Phoropter Arm (Positions)
The phoropter arm serves exclusively as the carrier for the phoropter. Do not any hang other
objects on the phoropter arm.
The power connection for a chart projector on the projector column has a maximum capacity
of 200 VA.
5.3.4 Contact lens fitting table with trial lens tray
The contact lens fitting table with the trial lens tray form a single unit and can be swung into
the required position in the same way as the translation table. (see chapter 5.3.1) These
elements will however not be influenced by the table lock.
The trial lens tray can be swung into position under the contact lens table using the handle.
Do not place any objects on the contact lens table that could scratch the mirror.
