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 opera­tions, troubleshooting, checking, maintenance and cleaning. To encourage the safe, efficient use of this instrument, carefully read "Displays for Safe Use" and "Safety Precautions."

To avoid injury, when moving the chinrest up/down, keep fingers away from moving parts.
To avoid injury, do not install the instrument on a slope or on an unstable place.
To avoid electrical shock, do not handle the power plug with wet fin­gers.
To avoid failure or potential injury, do not open the printer cover while the printer is in operation.
To avoid potential injury in case of malfunction, including a paper jam, be sure to shut off the power before attempting to repair it.
Never insert your fingers under the chinrest. * Inform the patient of this, too. Careless insertion of fingers may cause injury by pinching.
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.

To avoid potential injury, do not touch the printer body while the printer is in operation or when replacing the printer paper.
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.)
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 mea­surement.
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.
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.
Clean the measuring window glas s, meas ur ing nozz le and the w in­dow glass inside the measuring nozzle using ethanol. Other chemicals may cause damage to the patient's eye during measurement.

RESETTING FROM POWER SAVE STATUS

This instrument uses a power save system for saving electric power. When the main body is not in operation for approximately 10 minutes, power supply to the monitor is stopped. Under the power save condition, only the POWER lamp of control panel lights and the monitor screen is off.

The time for moving to the power save status can be changed by the initial setting "SETTING THE POWER SAVE TIME" (see page 47).

OPERATING THE CONTROL LEVER

Control lever operation includes coarse movement dynamically moving the measuring head and fine movement for fine adjustment. Also, by turning the control lever, the measuring head moves up/down. The Measurement switch is located at the top of the lever.
1 Coarse movement
When moving the measuring head back and forth or right/left, tilt the lever toward the desired direction and slide the tilted lever as is. Coarse movement occurs while the con­trol lever is being slid.
2 Fine movement
To move the measuring head back an d forth or right/left, tilt the control lever toward the desired direction. The amount of movement is increased as the tilt angle is increased.

3 Vertical movement
When the control lever is rotated, the measuring head moves up and down. Turning the lever clockwise will raise the measuring head and turning counterclockwise lowers it.
4 Measurement operation
Pressing the Measurement switch at the top of the control lever will start measurement.
During the AUTO measurement, continuously pressing the Measurement switch will effect the following movements: REF/KRT measurement: The buzzer rings twice and the automatic measurement stops. TONO/PACHO: While the Measurement switch is being pressed, automatic
measurement does not start even when alignment is reached, and starts when the switch is released.

POSITIONING THE PATIENT
Never insert your fingers under the chinrest.
CAUTION
* Inform the patient of this, too. Careless insertion of fingers may cause injury by pinching.
1 Make sure the MEASUREMENT screen is on. 2 Let the patient sit in front of the instrument. 3 Adjust the height of the automatic instrument table or the chair so that the patient can put
the chin on the chinrest with comfort.
4 Let the patient put the chin on the chinrest and stop the forehead at the forehead rest.
5 Pressing the or of the power supply section, adjust the height of the chinrest so
that the patient's eye becomes level with the height mark of the chinrest support.
Height mark
The chinrest moves up/down only while the button or button is pressed. If the chinrest does not work even when the button or button is pressed (a failure), turn off the , pull off the power cable, and call your
dealer or TOPCON at the address printed on the back cover of this manual.
