1 INTRODUCTION
1.1 Before using this manual
• This service manual is for the OPHTHALMIC YAG LASER SYSTEM YC-1600.
• Be sure to use this manual after understanding the operator’s manual for the OPHTHALMIC
YAG LASER SYSTEM YC-1600 thoroughly.
• This manual is subject to change without notice for improvement. Since the Technical Bulletin
will be released every time significant changes are made to the system, refer to the Technical
Bulletin together with this manual.
1.2 Before repairing
• Be sure not to lose or drop the removed screws inside the system.
• Apply a threadlocker to the screws which have been loosened and tightened again.
• Refer to the wiring diagram of the YC-1600 when repairing (see 7.1).
1.3 Handling and repairing of the laser head
• Be sure to turn OFF the power of the system when handling the laser head.
• Be sure to return the laser head to NIDEK for repair. Never disassemble, adjust and repair the
laser head.
NIDEK assumes no responsibility if the laser head is disassembled, adjusted and repaired.
1.4 Handling and repairing of the board and wiring
• Be sure to turn OFF the power of the system when handling and repairing the board and
wiring.
[WARNING]
Since Nd:YAG laser is an invisible infrared ray, it may cause the hazardous exposure to
radiation if the system is improperly handled and operated.
[CAUTION]
Be sure not to expose yourself to the laser beam at a place where the laser beam passes
through or is emitted when handling and repairing.
[CAUTION]
Be sure to use the safety goggles for the Nd:YAG laser.
1 - 1
XYC14*RDA001E/E
[CAUTION]
Never look straight at the Nd:Y AG laser even if the safety goggles are used.
[CAUTION]
Never touch the optical parts such as mirrors and lens directly .
[CAUTION]
Never emit the laser beam to the skin.
[CAUTION]
Pay attention not to get an electric shock when unavoidably opening covers to check or repair
the electrical parts.

XYC14*RDA001E/E
§
2 CAUTIONS
2.1 Cautions in laser emission
• Never emit the laser beam to personnel or things.
• Never touch the high voltage part (shown with mark) when emitting the laser beam since
there is a fear of an electric shock.
• Be sure not to drop metallic parts such as tools and screws into the laser system.
2.2 Handling of the laser head
• Never disassemble or repair the laser head.
Return the laser head to NIDEK if the repair is necessary.
2.3 Boards for repair
• The IC8 (EEPROM) on the MASTER BOARD which is supplied by NIDEK has already been
placed in the initial state. The setting values memorized in each EEPROM become optimum
for each system’s performance. As a result, the setting values may be varied according to each
system.
If using a new board, remove the IC8 (EEPROM) from the old one and attach it to a new one.
2.4 Cautions in checking connectors
• Visually check the connecting condition of connectors.
If the connector is almost disconnected, securely reconnect it.
• Verify the conditions of the contact pins and contacts.
• Cleaning of the contact pins
Clean the contacts with a spray which restores electrical continuity to them when dust or
oil makes them dirty.
• Verify the condition of the contact pins and contacts.
Disconnect the connectors and verify each cord by pulling a cord with the force approx. 1
kgf.
If the contact pin is removed, raise the hook of the pin using the precise screwdriver, and
insert it into the connector.
2 - 1
XYC14*RDA001E/E
2.5 Cautions in disconnecting cords
• If the heat-shrinkable tube covers the cord, remove it using nippers or knife.
• Use the soldering iron to remove the soldered parts.
• Remove the old solder adhered to the cord or terminal with the soldering iron.
2.6 Cautions in soldering cords
• If the cord was covered by the heat-shrinkable tube, run the cord through the tube.
• Solder the cords to bundle them before soldering the cord.
• Put the heat-shrinkable tube on the soldered part and constrict it using a heat gun.
2.7
Cautions in using the energy meter for the YAG laser
• According to the energy meter to be used, the necessity of the dispersion lens, which is attached
to the objective lens at the time of the energy measurement, is varied.
Refer to the table below when measuring the energy.
Energy meter Dispersion lens
MODEL-365 Necessary
MODEL PHDX50 Unnecessary
• There is a fear that the detector of the energy meter is damaged if the excessive energy density
is applied to the photoreceptor of the detector.
Be sure to maximize the spot size of the aiming beam on the photoreceptor as possible so that
the YAG laser never come into focus on the photoreceptor.
