Safety instructions

Replacing the probe base

Read this manual carefully, because it contains important information on using and servicing the tonometer.

After several months of use, dust may collect in the probe base, affecting the probe movement. The probe base should be replaced if the probe no longer moves smoothly.

Replacing the batteries

• Keep this manual for future use.

Technical information

Press the central button to clear error messages, after which the measurement can be repeated.

Type: TA01. The device conforms to CE-regulations. Dimensions: 13 – 32 mm (W) * 45 – 80 mm (H) * 230 mm (L). Weight: 155 g (without batteries) , 250 g (4 x AA batteries). Power supply: 4 x AA batteries. Measurement range: 1-99 mmHg. Accuracy of display: ±1. Measurement accuracy: ±2,8 mmHg (5-30 mmHg), 15% (30-80 mmHg). Display unit: Millimetre mercury (mmHg). The serial number is on the back of the battery compartment cover. There are no electrical connections from the tonometer to the patient. The device has B-type electrical shock protection. Storing/transportation environment: Temperature +5 to +40 °C Rel. humidity 10 to 80 % (without condensation)

The following messages may appear:

• When you have opened the package, check for any external damage or faults. Check especially that the casing is not damaged. If you suspect that there is something wrong with the tonometer, contact the manufacturer or the distributor.

Unscrew the battery compartment locking screw with a screwdriver or a small coin.

• Use the tonometer only for measuring intraocular pressure. Any other use is incorrect. The manufacturer cannot be held responsible for any damage arising from improper use, or for the consequences thereof. • Never open the casing of the tonometer, except for the battery compartment or to change the probe base.

• bAtt ... the batteries are low. Replace the batteries. • E01 ... The probe did not move at all. If this error message is repeated, turn the tonometer so that the collar faces down for a short time. If the error message is still repeated take out the probe and replace with a new one. If the error message continues to appear, replace the probe base. • E02 ...The probe did not touch the eye. The measurement was made from too far away or the probe base is dirty.

• The manual contains instructions for replacing batteries and changing the probe base. • Never use the tonometer in wet place. • The probe base, battery compartment cover, collar and probes are so small that a child could swallow them. Keep the tonometer out of the reach of children.

Unscrew the probe base collar and put it in a safe place.

Remove the battery compartment cover.

• Do not use the device near the substances that are flammable - including flammable anaesthetic agents.

• E03 ...Probe speed was too low. The measurement was made from too far away or the tonometer was tilted upwards too much.

• Be sure that the probe contains the small plastic round tip in front.

• E04 ...Probe speed was too high. The tonometer was tilted downwards. Be sure the groove is in the horizontal position.

• Certain microbiological agents (e.g. bacteria) can be transmitted from the forehead support. To avoid this, the forehead support should be cleaned regularly with a disinfectant, e.g. an alcohol solution.

• E05 ...The hit was too “soft”. The probe hit the eyelid.

• Check that a clean new disposable probe is used before each measurement.

• The tonometer must not come into contact with the eye, except for the probes for a fraction of a second during the measurement, therefore Do not bring the tonometer into contact with the eye or push it to the eye (tip of the probe should be 4-8mm from eye).

Remove the probe base by tilting the tonometer downward and pull the probe base out of the tonometer.

• The tonometer conforms to EMC requirements (IEC 60101-1-2: 2001), but interference may occur in it if used near to (<1m) a device causing high-intensity electromagnetic emissions (like a cellular phone). Though the tonometer’s own electromagnetic emissions are well below the levels in the relevant standards, they may cause interference in another device, e.g. a sensitive sensor, nearby.

0537 CAUTION -Indicates that important operating instructions are included in this User’s and Maintenance Manual.

Spare parts and supplies • Probes in one-use package. • Probe base replacement kit.

• E07 ...”Bad bounce”. The probe did not hit the central cornea.

Service procedures

• If the device is not to be used for a long time, removing the batteries is recommended, as the AA batteries may leak. Removing the batteries will not affect the subsequent functioning of the tonometer.

• Replace the batteries when the <bAtt> message appears. Put new AA batteries into the tonometer according to figures inside the battery compartment. + terminals should be down on the display side of the tonometer (behind). - terminals should be up on the measurement side (the front side).

• Be sure to dispose of the one-use probes properly (e.g., in a container for disposable needles), because they may contain micro-organisms from the measured patient. Put a new probe base into the tonometer.

• Batteries, packaging materials, and probe bases must be disposed of according to local regulations.

• Change the probe base if the probe does not move smoothly. • There are no other service procedures that can be carried out by the user. All other servicing and repairs must be carried out by the manufacturer or certified service facilities.

Screw the collar in, to lock the probe base.
