such use is necessary, this device and the other equipment should

be observed to verify that they are operating normally.

1.5 Operation, environment

DANGER!

• It is not permitted to make modifications to the measuring device.

• It is expressly forbidden to open the device.

• Never use the device in potentially explosive environments where

volatile solvents (alcohol, petrol, etc.) and flammable anaesthetics

are in use.

WARNING!

• The doctor or the operator is obliged to inform the patient about the

safety instructions concerning him and to ensure that these instruc-

tions are complied with.

• Only staff trained and experienced in the assessment of measuring

data and calculations and the manual entry, editing and deletion of

data may examine patients, operate the device and interpret results.

• All users must be appropriately trained and familiarised with the con-

tents of the instructions for use, especially with regard to the safety

instructions contained therein.

• Measurements can be carried out with dilated or undilated pupils.

Dilation of the pupil only influences measurement of the pupil dia-

meter (pupillometry).

• We recommend checking the calibration of the optional T-Cone

when fitting it and repeating this if necessary (see chapter 'Function

check').

• This device must not be operated near of high frequency surgical

equipment and the radio frequency shielded room of a medical elec-

trical system for magnetic resonance imaging, where the intensity of

electromagnetic disturbances is high.

• Portable radio frequency communications equipment (including peri-

pherals such as antenna cables and external antennas) should be

used no closer than 30 cm (12 inches) to any part of the device, in-

cluding cables specified by Haag-Streit. Otherwise, degradation of

the performance of this device could result.

NOTE!

• This device may only be used in accordance with the instructions in

the 'Intended purpose / intended use' chapter.

• Installation only by trained specialists.

• The PC on which the EyeSuite software is installed may not contain

any other software which could restrict the correct operation of Eye-

Suite.

• Please switch the computer off if it is not to be used for a long time.

• The device may not be transported, stored, handled or operated out-

side the specified ambient conditions (see chapter 'Ambient condi-

tions').

• The device is to be used in a room in the medical area with attenu-

ated light.

• If the device or accessories to it are exposed to the effects of an ex-

ternal force (e.g., by being accidentally knocked or dropped), this

sensitive measuring device must be promptly checked according to

chapter 'Function check' and, if necessary, returned to the factory for

repair.

• If the device is moved/transported, a functional check must be per-

formed in accordance with chapter 'Function check'.

• Perform a nullification and function check when prompted by the

software.

• The selected measuring mode must be checked before every meas-

urement.

• Keep these instructions for use in a place where they are accessible

at all times to those working with the device. Warranty claims can

only be made if the instructions for use have been complied with.

• The manufacturer of the device is not liable for loss or damage due

to unauthorised handling of the same. All warranty claims arising in

this case are null and void.

• Always remove the dust cover before switching the device on. The

device may otherwise become damaged due to overheating. Like-
