INTRODUCTION

Thank you for purchasing the TOPCON Auto Kerato-refracto-tonometer TRK-1P.

This instrument has the following features:

• Exact measurement of refraction power, corneal curvature, intraocular pressure and

central corneal thickness by simple operations

• Softer air blow in measuring intraocular pressure

•

Auto alignment and auto start functions enabling quick measurement under best conditions

This text outlines the Auto Kerato-refracto-tonometer TRK-1P and describes basic opera-

tions, troubleshooting, checking, maintenance and cleaning.

To encourage the safe, efficient use of this instrument, carefully read "Displays for Safe

Use" and "Safety Precautions."

Also, keep this Instruction Manual in a convenient location for your future reference.

PRECAUTIONS

• This is a precision instrument, install/store it in a place with the following conditions: tempera-

ture (10 to 40

°C), humidity (30 to 75%) and atmospheric pressure (700 to 1060hPa). Avoid

direct exposure to sunlight.

• To ensure smooth operation, install the instrument on a leveled stand free of vibrations. Also, do

not place any objects on the instrument.

• Before using the instrument, connect all cables correctly.

• Use the specified source voltage.

• When not in use, turn off the power and put the measuring window lens cap and dust cover on.

• To ensure the correct reading, do not mar the measuring window with finger prints, dust, etc.

Also, do not touch the measuring nozzle except during cleaning.

[WARNING]

When operating the instrument, be not touch the patient's eye or nose.

[WARNING]

To prevent corneal damage, do not measure a patient with corneal disease or corneal surgery.

109

To avoid injury, when moving the chinrest up/down, keep fingers

away from moving parts.

8

To avoid injury, do not install the instrument on a slope or on an

unstable place.

33

To avoid electrical shock, do not handle the power plug with wet fin-

gers.

34

To avoid failure or potential injury, do not open the printer cover

while the printer is in operation.

86

159

To avoid potential injury in case of malfunction, including a paper

jam, be sure to shut off the power before attempting to repair it.

86

159

Never insert your fingers under the chinrest.

* Inform the patient of this, too.

Careless insertion of fingers may cause injury by pinching.

98

113

Do not use or apply any spray-type cleaner near the instrument.

If the cleaner remains inside the measuring nozzle, the patient's

eye may be injured during measurement.

161

When operating the instrument, be careful not to touch the patient's

eye or nose.

cause injury, as well as damage to the instrument.

33

CAUTION

6

When setting an instrument on an instrument table, pay attention

not to injure the patient's fingers between the instrument and the

table.

33

To avoid potential injury, do not touch the printer body while the

printer is in operation or when replacing the printer paper.

86

159

Before starting measurement, be sure to confirm the measuring

screen (to avoid making the ocular pressure measurement to the

patient's eye wearing a contact lens.)

101

106

119

126

Before measuring, check if there is any foreign matter on and

around the measuring nozzle.

If any, it may enter and damage the patient's eye during the mea-

surement.

110

Before measuring, set the safety stop to prevent the measuring

window glass from hitting the patient's eye.

Set it respectively for the right and left eyes.

114

Set the safety stop from the side face of the instrument.

Setting operations from other positions, where checking of the eye

position is not easy, may cause injury.

114

Clean the measuring window glass, measuring nozzle and the win-

dow glass inside the measuring nozzle using ethanol.

Other chemicals may cause damage to the patient's eye during

measurement.

156

157

This instrument has been tested (with 100/120/230V) and found to

comply with IEC60601-1-2: Ed.2.1: 2004.

This instrument may emit a radio frequency energy (within the stan-

dard) and cause an adverse effect on the devices located nearby.

When such effect is confirmed by the ON/OFF operation, a proper

treatment as to change the direction, use another outlet, etc. is rec-

ommended. If the problem remains unsolved, call your dealer.
