[CONTRAINDICATION AND PROHIBITION]
When you emit the laser beam of this instrument to the human organic tissues, the
following symptoms may occur. Always be careful about the purpose position of
the aiming laser. Don't emit the laser beam to others except the treatment position.
Symptom of eyes: Injury in cornea and others or loss of sight
Symptom of skin : Pain or burn
[Human organic tissues may be damaged.]
During operation, let the people around the instrument wear the goggles (applied to
532nm, OD4 or more) suitable for the laser wavelength. Even when you wear the
goggles, do not watch the laser beam directly.
[Your eyes may be injured.]
Use the components specified by TOPCON.
[If you use the instrument wrongly, it may malfunction.]
[WARNING]
When operating the instrument, be careful not to hit the eyes or nose of the patient
by it.
[The patient may be injured.]
[WARNING]
When the arm of the slit lamp attachment for laser photocoagulator is retreated, do
not emit the laser.
[The eyes and skin may be burned or injured by the laser beam.]

CAUTIONS FOR USE
Before using this instrument, read the instruction manual. Fully understand the cautions for safety and the
use method.
Caution for use (Don't apply the instrument to the following patients.)
Patients whose treatment tissues cannot be properly checked (cloudy cornea, cataract, cloudy crystal-
line lens)
Important basic cautions
Give a detailed explanation to the patient about the expected effects and harmful symptoms before
operation.
Tell the patient not to move his/her body (especially, head) carelessly during operation.
Handling
Don't use this instrument where there are a combustible anesthetic, oxygen gas or other mixed gases.
[Explosion may occur.]
When the instrument is under observation or other conditions except laser emission, set it in the
standby mode.
[It may emit the laser beam wrongly.]
Keep your place at the instrument during operation. If the operator must leave the instrument, set the
key switch to "OFF", remove the key from the instrument and store it in a proper place.
[Others except the operator may use the instrument to cause an accident.]
Before emitting the laser, make sure that there is no reflective matter in its optical path.
[The laser beam may be emitted in an unexpected direction.]
In the inspection before using the instrument, make sure that the optical axis of the aiming beam is fit to
that of the treatment beam.
[The laser beam may not be emitted correctly.]
Be careful not to damage the optical components and soil them with fingerprint, dust, etc.
[The laser emission function may be deteriorated.]
When moving the chinrest up and down, be careful not to catch the patient's hand.
[The patient may be injured.]

SAFETY CAUTIONS
Icons Prevention item Page
Prohibition
The endoprobe is a sterilized disposable product. Do not use it if the
sterilizing outer package gets wet (even once) or damaged, or if the
sealing is damaged. 32
Prohibition Do not use the endoprobe if its validity time has expired. 32
Prohibition When using the endoprobe, do not rebuild it in any way. 32
Prohibition
Both the beam and diffused beam are dangerous. Do not look at/
touch these. 34, 38
Mandatory Action
During operation, let the people around the instrument wear the
goggles (applied to 532nm, OD4 or more) suitable for the laser
wavelength. The laser beam may damage their eyes. 34, 38,
74
Mandatory Action
First, make sure that the slit lamp attachment for laser photocoagula-
tor is at the specified position and then turn on the power of the
instrument. If it is not at the specified position, it may cause exposure
to laser beams and resultant burns and loss of sight. 34
Mandatory Action Firmly fasten screws and avoid death/injury due to falling. 49
Mandatory Action
Fix the protect filter between microscope body and the binocular tube,
and protect the eye from laser beams. 49
Prohibition
Do not open covers to avoid the danger of electric shocks. Ask a
service engineer for repairs. 52
Prohibition
Repairs/adjustments should always be done by the service engineer.
Electric shocks due to careless handling may cause death or serious
burns, and exposure to laser emission may cause burns and loss of
sight. 52
Mandatory Action
When changing fuses, shut down the power supply and pull off the
power cable. Removing the fuse cover without removing the power
cable may cause electric shocks. 57, 59
Mandatory Action
Be sure to use the attached fuse. Using another fuse may lead to fire
in case of a failure. 57

Icons Prevention item Page
Mandatory Action
For installation, prepare a power supply system satisfying the rating of
AC 100V, 120V, 220V or 240V and a capacity of 550VA and larger.
Use with a voltage other than the displayed voltage may cause injury
by electric shocks and fire. 28
Mandatory Action
For installation, prepare a power supply system allowing protective
grounding, and surely arrange protective grounding. Leaks without
protective grounding may lead to fire and electric shocks. 28
Prohibition
When the remote interlock is released, the laser beam is emitted.
Both the beam and diffused beam are dangerous. Do not look at/
touch these. 29
Prohibition Do not touch the endoprobe end. 32
Mandatory Action
Install the remote controller in a stable place to prevent injury by falling
off. 33
Prohibition
The laser beam is emitted from the laser beam outlet. Keep your face
off the outlet as the beam may burn your eyes and skin. 34, 38
Mandatory Action
Use this instrument following the procedure described in the Manual.
Controls and/or adjustments by procedures other than those
described here may cause exposure to laser beams and resultant
burns and loss of sight. 34
Prohibition
Place the Footswitch in a position where it is not in the way. To avoid
stumbling/injury to your foot, do not step too deep into the switch. 34, 38,
74
Mandatory Action
Before using, surely adjust the diopter and interpupillary distance.
Incorrect adjustments will lead to improper treatment. 38, 44,
47, 74
Mandatory Action
Before using, surely adjust the focus and position of the aiming beam.
Incorrect adjustments will lead to improper treatment. 38
Mandatory Action
When operating the main unit, watch the space between the moving
parts and protect your fingers. 45
Mandatory Action
When operating the main unit, watch the patient's face and protect the
eyes and nose from the instrument. 45
Prohibition
Set the illumination for a proper brightness. An excessive brightness
will not only bother the patient but may cause damage to the eye. 46
Prohibition
Don't use the test rod for focus adjustment. Focus is not fit when
treatment is done for a patient. Correct treatment is not possible. 48
Prohibition
Do not use chemicals for cleaning, such as caustic cleansers to avoid
exfoliation of nameplates and damage to letters. 57
