INTRODUCTION
Thank you for purchasing the TOPCON Computerized Tonometer CT-1P/CT-1.
INTENDED USE / INDICATIONS FOR USE
Measuring intraocular pressure through the cornea based on the tension of the eye ball, to provide
information for diagnosis.
Measuring the corneal thickness to adjust intraocular pressure(only in CT-1P).
FEATURES
This instrument features the following:
• The position of the touch panel can be adjusted to accommodate the user's preferred position.
• Softer air puff for measuring intraocular pressure.
• Auto alignment function enables quick easy measurement under optimal conditions.
PURPOSE OF THIS MANUAL
To get the best use of the instrument, read GENERAL SAFETY INFORMATION and DISPLAYS AND SYM-
BOLS FOR SAFE USE.
Keep this Manual at hand for future reference.
• Since this product is a precision instrument, always use and keep it in a normally controlled living environ-
ment, within a temperature range of 10-40°C, humidity levels between 30-90% and an atmospheric pres-
sure range of 700hPa-1,060hPa.
The instrument should also be placed away from direct sunlight.
• To ensure smooth operation, install the instrument on a level floor free of vibrations. Also, do not place
anything on the instrument.
• Connect all cables properly before using.
• Use the power at a rated voltage.
• When not in use, switch off the power source and apply the rubber cap and dust cover.

GENERAL SAFETY INFORMATION
Ensuring the Safety of Patients and Operators
When operating the instrument, do not touch the patient's eye or nose.
To prevent corneal damage, do not measure a patient with corneal disease or one who’s
had corneal surgery.
To prevent corneal damage, do not measure a patient wearing a contact lens.
Tell the patient to remove the contact lens.
Handling the cord on this product or cords associated with accessories sold with this prod-
uct, will expose you to lead, a chemical known to the State of California to cause birth
defects or other reproductive harm. Wash hands after handling.
Preventing Electric Shocks and Fire
To avoid fire and electric shock, install the instrument in a dry place free of water and other
liquids.
To avoid electric shock, do not insert metal objects into the instrument body through the
vent holes or gaps.
To avoid fire and electric shock, do not put cups or other containers with liquids near the
instrument.
To avoid fire in the event of an instrument malfunction, immediately turn OFF the power
switch " " and disconnect the power plug from the outlet if you see smoke coming from the
instrument, etc. Don't install the instrument where it is difficult to disconnect the power plug
from the outlet. Ask your dealer for service.
WARNINGS

8
Ensuring the Safety of Patients and Operators
To avoid injury when operating the up/down button for the chinrest, be careful not to catch
the patient's fingers.
During alignment operation, please pay attention so that a patient's face does not move.
If the face moves, there is a danger that the main body will touch the patient's face.
The light emitted from this instrument involves potential risk; the longer the irradiation time,
the more risk of damage to the eye.
When the instrument operates with the maximum light volume, exposure for more than 2
hours will exceed the safety guideline.
Preventing Electric Shocks and Burns
To avoid injury by electric shock, do not open the cover. For repair, call your service engi-
neer.
To avoid injury by electric shock when changing the fuse, turn off the power supply and pull
out the power cable. Use the rated fuse.
Electromagnetic Compatibility (EMC)
This instrument has been tested (with 100/120/230V) and found to comply with IEC60601-
1-2:Ed.3.0:2007. This instrument radiates radio frequency energy within standard and may
affect other devices in the vicinity. If you have discovered that turning on/off the instrument
affects other devices, we recommend you change its position, keep a proper distance from
other devices, or plug it into a different outlet. Please consult your authorized dealer if you
have any additional questions.
