3. WARNINGS
NOTE : THIS INFORMATION IS BELIEVED TO BE CURRENT AT THE TIME OF
PUBLICATION, BUT IS PROVIDED WITHOUT WARRANTY OF ANY KIND AND
WE ASSUME NO RESPONSIBILITY WITH RESPECT THERETO.
1) SERVICE AND REPAIR OF THE SYSTEM SHOULD BE RESTRICTED QUALIFIED
TECHNICAL PERSONNEL AUTHORIZED BY OPTIKON 2000.
2) THE "OPTIKON OPTIKON ASSISTANT" CONTROL CONSOLE IS PROVIDED WITH A
VOLTAGE CHANGER. CHECK THAT THE CONSOLE IS SET TO THE PROPER
VOLTAGE BEFORE CONNECTING TO A MAINS SUPPLY. TO GUARANTEE SAFETY, A
HOSPITAL GRADE POWER CORD AND PLUG MUST BE USED, THE UNIT MUST BE
GROUNDED.
NOTE: SETTING A DIFFERENT INPUT VOLTAGE MAY REQUIRE REPLACING THE
MAINS FUSES. REFER TO THE TECHNICAL SPECIFICATIONS PARAGRAPH.
3) THE SYSTEM SHOULD NEVER BE USED IN THE PRESENCE OF FLAMMABLE
ANAESTHETICS, DISINFECTING AGENTS, CLEANING AGENTS, ETC., DUE TO
POSSIBLE FIRES OR EXPLOSION.
4) TO REDUCE THE RISK OF ELECTRIC SHOCK, UNPLUG THE EQUIPMENT FROM THE
MAINS BEFORE REMOVING COVER FOR SERVICING.
5) THE ASSISTANT CONTROL CONSOLE SHOULD BE CONNECTED TO A MAINS
SUPPLY ONLY AS MARKED ON THE REAR PANEL. TO GUARANTEE SAFETY, A
HOSPITAL GRADE POWER CORD AND PLUG MUST BE USED, THE UNIT MUST BE
GROUNDED.
6) FOR OPERATING SAFETY DO NOT INSTALL THE SYSTEM IN A LOCATION WHERE IT
WILL BE EXPOSED TO HEATING EQUIPMENT OR RADIATORS, DIRECT SUNLIGHT,
OR ANY OTHER SOURCE OF EXTREMELY HIGH TEMPERATURES.
7) DO NOT INSTALL THE ASSISTANT SYSTEM IN SUCH A WAY THAT THE VENTILATING
OPENINGS ARE BLOCKED.
8) BE SURE THAT THE POWER SWITCH ON THE CONTROL CONSOLE IS OFF WHEN
PLUGGING IN, OR REMOVING THE POWER CABLE FROM A WALL OUTLET.
9) TURN OFF THE MAIN POWER SWITCH WHENEVER THE ASSISTANT UNIT IS NOT IN
USE.
10) RISK OF BURNS OR FIRE; DO NOT USE DIATHERMY NEAR CONDUCTIVE
MATERIALS SUCH AS METAL BED PARTS, INNER-SPRING MATTRESSES, AND THE
LIKE. RENEW ELECTRODE CABLES UPON EVIDENCE OF DETERIORATION.

Assistant Service Manual
OPTIKON 2000
Code 121008S 3-2 Rev. D
11) SEVERE RF BURNS CAN RESULT IF THE DIATHERMY OUTPUT CURRENT IS
DIVERTED TO THE OPERATOR BY CARELESS HANDLING.
12) WHEN THE BIPOLAR DIATHERMY HANDPIECE AND A MONITORING SYSTEM ARE
USED AT THE SAME TIME, ALL THE ELECTRODES OF THE MONITORING SYSTEM
THAT ARE NOT PROTECTED BY RESISTORS OR HIGH FREQUENCY INDUCTORS
SHOULD BE PLACED AS FAR AWAY AS POSSIBLE FROM THE DIATHERMY
ELECTRODES.
13) THE CABLE OF THE BIPOLAR DIATHERMY HANDPIECE SHOULD NOT TOUCH THE
PATIENT OR OTHER CABLES.
14) ALWAYS USE THE LOWEST OUTPUT DIATHERMY POWER LEVEL WHICH IS
COMPATIBLE TO THE SURGICAL APPLICATION.
15) AN EVIDENT LOW OUTPUT LEVEL OR A FAULTY OPERATION OF THE BIPOLAR
DIATHERMY HANDPIECE, EVEN THOUGH THE INSTRUMENT HAS BEEN SET FOR A
NORMAL USE, MAY INDICATE A BAD CONTACT IN THE ELECTRODES CONNECTION.
16) DURING BIPOLAR DIATHERMY HANDPIECE OPERATION, DO NOT USE FLAMMABLE
ANAESTHETICS NITROGEN MONOXIDE, OXYGEN, UNLESS THEY ARE VENTED BY A
SUITABLE ASPIRATION SYSTEM.
17) FLAMMABLE MATERIALS SUCH AS DISINFECTING AGENTS AND CLEANING AGENTS
SHOULD BE EVAPORATED BEFORE USING THE BIPOLAR DIATHERMY HANDPIECE.
SOME MATERIALS SUCH AS COTTON WOOL OR GAUZE, IF SOAKED WITH OXYGEN,
CAN CATCH FIRE BECAUSE OF THE SPARKS CAUSED BY THE INSTRUMENT IN ITS
NORMAL USE.
18) THERE IS A POSSIBLE RISK FOR PATIENTS CARRING CARDIAC STIMULATOR OR
STIMULATING ELECTRODES BECAUSE OF RF INTERFERENCE CAUSED BY
DIATHERMY GENERATOR. THE STIMULATOR ITSELF CAN FAIL. SHOULD ANY
DOUBT ARISE, APPLY TO THE CARDIOLOGY DIVISION FOR ADVICE.
19) CAUTION: POSSIBLE INTERFERENCE WITH OTHER MEDICAL EQUIPMENT WHEN
THE BIPOLAR DIATHERMY HANDPIECE IS IN USE.
20) EXCHANGING FUSES AND HALOGEN LAMPS SHOULD BE DONE A FEW MINUTES
AFTER THE MAINS SWITCH HAS BEEN TURNED OFF IN ORDER TO ALLOW TIME
FOR COOLING.
21) REPLACE FUSE AS MARKED.
22) NEVER LIFT OR MOVE FOOTSWITCH BY THE CABLE. DAMAGE MAY RESULT.
23) DO NOT ALLOW THE TIP OF THE VITRECTOMY PROBE, DIATHERMY, OR I/A
HANDPIECE TO TOUCH METALLIC OBJECTS.
24) DO NOT ATTEMPT TO ALTER THE SHAPE OF ANY PART OF A HANDPIECE.
25) DO NOT ATTEMPT TO SEPARATE THE PLUG FROM THE CABLE.

Assistant Service Manual
OPTIKON 2000
Code 121008S 3-3 Rev. D
26) DO NOT SUBJECT THE HANDPIECE TO HOT AIR STERILIZATION OR "CHEMCLAVE".
27) DO NOT STORE OR USE THE HANDPIECE IF WET OR MOIST.
28) ALTHOUGH THE FIBER OPTIC ENDO-OCULAR ILLUMINATION SYSTEM IS PROVIDED
WITH SAFETY FILTERS TO MINIMIZE EMISSION OF INFRA RED AND ULTRA VIOLET
RADIATION, TO AVOID POSSIBLE DAMAGE TO THE RETINA, ALWAYS USE THE
MINIMUM LIGHT POWER LEVEL WHICH IS COMPATIBLE TO THE SURGICAL
APPLICATION.
29) TO REDUCE THE HAZARD OF RETINAL DAMAGE, DO NOT GO WITH THE EDGE OF
THE FIBER OPTIC ILLUMINATION PROBE IN THE IMMEDIATE PROXIMITY OF THE
RETINA.
30) DO NOT ACTIVATE THE VITRECTOMY HANDPIECE WITH THE TIP IN AIR. THE TIP
SHOULD ALWAYS BE TEST RUN IN A BEAKER OF STERILE SOLUTION. TESTING IN
AIR WILL CAUSE IRREPARABLE DAMAGE TO THE TIP.
31) HANDPIECES AND OTHER NON DISPOSABLE ACCESSORIES ARE SUPPLIED NON
STERILE. THEY MUST BE FIRST CLEANED, THEN STERILIZED IN AUTOCLAVE AS
INDICATED ON THE RELATIVE INSTRUCTIONS. THEY COULD BE DAMAGED BY THE
USE OF OTHER STERILIZATION METHODS, LIKE HOT AIR OR "CHEMCLAVE"
STERILIZATION.
32) THE USE OF INFLAMMABLE ANAESTETICS, (N
2
0 ), ( 0
2
), SHOULD BE AVOIDED
UNLESS THEY ARE REMOVED BY A GAS ASPIRATION SYSTEM.
33) DO NOT ACTIVATE THE PHACO U/S HANDPIECE WITH THE PHACO TIP IN AIR. THE
ULTRASONIC POWER SHOULD BE APPLIED TO THE PHACO HANDPIECE WITH THE
PHACO TIP IMMERSED IN A TEST CHAMBER FILLED WITH INFUSION FLUID OR IN A
BEAKER OF STERILE FLUID AT AMBIENT TEMPERATURE. OTHERWISE HANDPIECE
DAMAGE MAY RESULT.
34) DO NOT CHECK VIBRATION BY PLACING HAND OR FINGER AGAINST HANDPIECE
TIP. PROLONGED EXPOSURE TO OR DIRECT CONTACT WITH THE VIBRATING TIP
MAY CAUSE DAMAGE TO HEALTHY TISSUE.
35) THE PHACO HANDPIECE MUST BE CONNECTED TO THE ASSISTANT IRRIGATION-
ASPIRATION SYSTEM AND MUST NOT BE USED WITHOUT IT.
36) AN EXTERNAL STERILIZING FILTER MUST BE INSERTED TO THE AIR SOCKET TO
PREVENT INFECTIONS. THE FILTER IS INTENDED FOR SINGLE USE AND MUST BE
REPLACED AT ANY NEW SURGERY.
37) THE USE OF NON STANDARD AIR SUPPLY TUBING KIT, MAY COMPROMISE THE
ACCURACY OF INTRAOUCULAR AIR PRESSURE.
38) DURING SILICONE OIL INJECTION, THE INTRA-OCULAR PRESSURE IS NOT
CONTROLLED BY THE ASSISTANT UNIT. THEREFORE, THIS IOP CONTROL IS
UNDER THE SURGEON’S RESPONSIBILITY. IT'S IMPORTANT TO CHECK SILICONE

Assistant Service Manual
OPTIKON 2000
Code 121008S 3-4 Rev. D
FLOW (CORRESPONDING TO THE PRESET INJECTION PRESSURE) BEFORE
INSERTING THE CANNULA IN THE EYE. FOR A BETTER FLOW CONTROL DO USE
1000 CS SILICONE OIL.
39) TO STOP SILICONE OIL INJECTION RELEASE THE INJECTION SWITCH. IN CASE OF
EMERGENCY CONDITIONS CLOSE THE INJECTION STOPCOCK OR DETACH THE
SILICONE INFUSION LINE FROM THE SILICONE DELIVERY DEVICE.
40) BEFORE USING A SURGICAL OR NON SURGICAL ACCESSORY IN CONNECTION
WITH ASSISTANT, VERIFY THE COMPATIBILITY OF THE SAME WITH ASSISTANT
EQUIPMENT. COMPATIBILITY IS STATED ON THE ACCESSORY ACCOMPANYING
DOCUMENT.
41) DISPOSE WASTE COLLECTION FLUIDS ACCORDING TO THE LOCAL
LAWS/REGULATIONS ON DISPOSAL OF ORGANIC MATERIALS.
42) WHEN AIR INJECTION IS ACTIVE, AN INTERMITTENT BEEP (0.9 SEC PERIOD) IS
GENERATED BY THE EQUIPMENT AS A WARNING SIGNAL.
43) SOUND EMISSION CAPABILITY OF THE EQUIPMENT IS TESTED AT POWER-ON.
VERIFY THAT AN AUDIBLE BEEP IS EMITTED DURING SYSTEM BOOT.
44) A ROTATING LOGO, PLACED AT THE LOWER SIDE OF THE USER INTERFACE
SCREEN, SHOWS THAT THE SYSTEM IS RUNNING PROPERLY. IF SUCH SYMBOL
STOPS MOVING IT MEANS THAT THE SYSTEM IS IDLE AND EQUIPMENT OPERATION
MUST BE STOPPED.
45) THE SILICONE INJECTION STOP VALVE IS TESTED AT POWER ON. VERIFY THAT NO
GAS LEAKAGE IS AUDIBLE DURING SYSTEM BOOT.
46) A VERY HIGH VOLTAGE (20KV) IS DELIVERED TO THE LAMP AT POWER ON FOR
IGNITION: DO NOT TOUCH INNER CABLE AND WIRING WHILE SWITCHING THE
LAMP ON. DO NOT POWER ON THE LIGHT IF THE ILLUMINATION MODULE WIRING
IS DISCONNECTED..
47) THE HID LAMPS OF THE ASSISTANT CONTAIN GAS AT A VERY HIGH PRESSURE.
THEY MAY EXPLODE CAUSING SERIOUS INJURIES TO THE EYES: WEAR
PROTECTIVE GOGGLES DURING BULB REPLACEMENT AND CALIBRATION. HANDLE
WITH EXTREME CARE. DO NOT TOUCH THE GLASS OF THE BULBS WITH FINGERS
AS STAINS AND GREASE MAY CAUSE LAMP EXPLOSION.

1) IRRIGATION PINCH VALVE
The valve allows starting and sto ing irrigation at surgeon’s demand.
2) REFLUX PINCH VALVE
The Reflux/Venting inch valve ermits introduction of fresh BSS solution
in the as iration line, thus releasing the vacuum in the line and,
eventually, reversing direction of flow.
3) ACS3 VACUU SENSOR
The ACS3 vacuum sensor monitors the vacuum level in the as iration line in
a sterile manner. It also revents sudden vacuum surges, thus stabilizing
the anterior chamber.
4) PERISTALTIC PU P
This um allows eristaltic as iration in the ASSISTANT. The um rotor is
automatically moved to allow tubing installation and/or Venturi as iration.
5) I/A CASSETTE RELEASE BUTTON
