3.3 Installation

3.3.1 Instrument Table

The instrument table is delivered in a separate package. Utilize the instructions included with the table to put the table together and
take care to select the correct voltage before connecting the power cord.

3.3.2 OCTOPUS 300

Handle the instrument using both lower housing halves to lift it out of the packing. Two ribbed grips hinder sideways slipping.

Since the OCTOPUS 300 works without a cupola, a fully darkened room is not required. In order, though, to make the examination
conditions pleasant for the patient and for obtaining reliable results, the instrument is to be placed in the room so that no direct light
falls on the instrument or the patient.

The positioning between the patient and the operator or the operating panel can be so chosen that the room conditions are optimally
used.

The connector housing for the ‘Patient response
button’ is accessible from below on the headrest

support. The catches on the Patient response button
connector are oriented in the direction of the
instrument column.

ATTENTION: Besides the ‘Patient response

button’ no other cable should be

attached to the RJ11 connector.

Tradition and Innovation

 Loosen the three Allen head screws roughly 2 turns counterclockwise on the perimeter of the headrest holder (Allen wrench is

included with the accessories) and turn the headrest together with the optical unit into the desired position. Tighten the three
Allen head screws again. A complete rotation around the column is blocked by a built in limit.

 Place the instrument on the table so that the opening of the table foot and the headrest are in the same direction.
 Connect the ‘Patient response button’ to the connector located on the support of the headrest.

 Stick the connector plug so far into the connector housing that the catches audibly click. To remove the ‘Patient response

button’, press the catches in the direction of the headrest and pull out the cable downwards.

 If the examination data are to be transmitted to a PC, connect the OCTOPUS 300 and the PC with the serial connection cable.
 Plug the power cord in. The built in ‘Power supply’ works with the voltage specified in Chapter 10.1 'Technical Data'. A change

of voltage on the instrument is not required. If an instrument table was delivered with the unit, the OCTOPUS 300 can be
connected using the power socket in the electronics box of the instrument table.

4 SOFTWARE

4.1 Installation, Exchange, Upgrade

For application software installation and upgrade refer to Chapter 7.14.1 'SIM Flash Module, Application Software (1802222).

4.2 Releasing Program Options

Some of the functions of the OCTOPUS 300 are offered as options and are not accessible in the basic version of the software.
Basically all the functions are present in the software, but some can only be made accessible with a code. This code is delivered by
HAAG STREIT and is then entered by the customer or the service technician into the instrument. Information about such additional
functions can be obtained directly from HAAG STREIT or from your representative.

4.2.1 Procedure

Procedure to make additional functions accessible in the perimeter.

IMPORTANT: The 'Dongle code' function is only used, when additional program options have been purchased. To avoid

free access and faulty manipulations the function is protected. The 'Dongle' button is only released after the
two headrest sensors and the 'Dongle' button are pressed at the same time. As from Serial No. 1031 the
head rest sensors have been replaced with non-contact head sensors. In this case hold your hand (close) in
front of the head rest and simultaneously press the ‘Dongle’ button.

5 PRINCIPLE OF OPERATION

HAAG-STEIT is the only company offering perimeters with direct projection systems (OCTOPUS 300, 1-2-3). By means of the
‘Optical unit’, which is replacing the cupola, stimuli are directly projected into the patient eye. This technique does not require dark
room condition to take a visual field.

5.1 Functional Diagram

5.2 Stimulus Intensity Control

The required dynamic range of the stimulus intensity of 40 dB (1:10'000) is achieved with a combined control mode:

Tradition and Innovation

5.2.1 Current Control

Two current reference values (operating points) are ascertained during the stimulus calibration procedure:

 Operating point OP1: 0dB (max. stimulus intensity)
 Operating point OP2: 20dB (max. stimulus intensity/100)

Thus the entire dynamic range is divided into two segments:

 Segment 1 / operating point OP1: 20dB ... 0dB
 Segment 2 / operating point OP2: 40dB ... 20dB

Figure 5-3: Stimulus LED current control

5.2.2 Pulse-width Modulation

A typical stimulus of 100ms duration is formed by a burst of 20 5ms pulses. The width (ratio LED switch-on/LED switch-off time) of
the 20 pulses can be increased or decreased by processor control in steps of 0.4s (12'500 steps for 5ms). With a longer switch-on
time the LED is emitting light for a longer time period, resulting to the human eye, which has an integrating characteristic, in an
impact of higher brightness. Pulse-width and light emission are proportional. Pulse-width modulation and stimulus duration are
controlled by the microprocessor software through logic timer signals.

OCTOPUS 300 Service Manual Page 13 / 64

Tradition and Innovation

Figure 5-4: Stimulus LED pulse-width modulation

5.3 Background Intensity Control

The light source for the background illumination consists of a number of white LED’s. During initialization of the perimeter the
background brightness is measured by a photo sensor and controlled by a DAC value. Pulse-width modulation is not used for
background illumination.

5.4 Reference Point

During initialization of the perimeter the stimulus projection unit is centered to the optical system (position x/y = 0/0). The photo
sensor for background illumination calibration is used as reference point.

7 MAINTENANCE AND REPAIR

WARNING: Before opening the instrument make sure that the mains cable is separated from the instrument.

WARNING: Some of the modules need alignment after being exchanged. Therefore it is important to go through all the steps

described in exchanging the module that needs to be replaced.

WARNING: Electronic circuits of the OCTOPUS 300, particularly the 'Processor board', the 'Interface board' and the LEDs in

the 'Background LED module' are all very sensitive to electrostatic charges. Keep all modules in static shielding
bags for storage, transportation and shipping.

Besides an ordinary set of regular tools the following tools and instruments are recommended:

 Set of Allan- (hexagonal) wrenches, metric 1.3 to 8mm
 Set of Torx screwdrivers (the sizes in this manual refer to the screwdriver size)
 Universal digital voltmeter, range 200mV to 250V

Cleaning Materials

 Can of compressed air
 Lens tissue
 Lens cleaner (diluted alcohol)
 Cotton swabs

Whenever possible, field repairs of the OCTOPUS 300 should be restricted to module exchange. The sub module (part) causing a
problem should be localized with the help of the service manual and error list. It should then be replaced with an exchange module.
