INITIAL INSPECTION
Please inspect the shipment immediately upon delivery. Check the received goods against the
packing list to insure that all items were received. If the shipment is missing items, or is damaged
in any way, you will need to contact the freight carrier. You should also contact Kigre's
Customer Service Department (the address is on the front page) or your local Representative
for assistance with your claim.
WARRANTY
Unless otherwise specified, all laser power system products manufactured by Kigre are warranted to be free from
defects in workmanship and materials for a period of one (1) year following delivery of the equipment to the F.O.B.
point.
Liability under this warranty is limited to, at Kigre's option, repairing or replacing the part or product which is
determined by Kigre to be defective during this warranty period, provided prior authorization for such return has
been given by an authorized representative of Kigre and the product is returned, prepaid, to Kigre within thirty (30)
days from discovery of the defect. Equipment repaired or replaced under warranty are warranted only for the
remaining unexpired portion of the original warranty period.
This warranty does not apply to laser power system products which upon inspection by Kigre are determined to have
been damaged through improper storage or installation, misuse, neglect, accident, or for any cause beyond Kigre's
control. Repair or alteration of any part of the laser power system by person other than Kigre authorized personnel
immediately voids this warranty.
Buyer assumes all risk and liability for the results obtained by the use of any product delivered hereunder and in no
event shall Kigre be held responsible for special or consequential damages or charges. When products manufactured
by others are used in conjunction with Kigre equipment, this warranty only extends to the equipment manufactured
by Kigre.
This warranty is in lieu of any and all warranties or representations, expressed or implied, and no agreement or
understanding affecting this warranty shall be binding upon Kigre unless in writing and signed by an authorized
representative of Kigre.
Kigre reserves the right to make changes to its products without incurring the obligation to incorporate such changes
in products previously purchased and delivered to the buyer.
RETURN PROCEDURE
Your Kigre laser system is designed and constructed to provide years of trouble free service.
Should your system require service, return it to our service facility by contacting our Customer
Service Department for a Return Material Authorization number (RMA#). You will need to
provide the model and serial number of the damaged equipment and a brief description of the
failure. Return shipments should be made prepaid. Kigre will not accept C.O.D. or collect return
shipments. Damages caused by inadequate packaging will not be covered under the warranty.

INTRODUCTION
The MK-367 (or MK-480) laser was developed primarily for the ophthalmic range-finder
markets as a permanently aligned, reliable, low cost laser requiring minimal service and having a
usable life in excess of 300,000 shots. The MK-1000 system adds the following components to
the MK series laser:
! AC to DC power supply
! Hand Controller
! Pulse Forming Network (PFN) and High Voltage (HV) Power Supply (PS) unit
! Trigger Module
1. AC to DC Power Supply
! 12VDC 10W output
! 100-130VAC 15W input
2. Hand Controller
! ON/OFF toggle (enables HV)
! Fire Button
! HV status LEDs (Green = charged, Red = not charged)
! HV program adjustment dial
3. PFN and HVPS
! MK106-10 units: 6W, 20uF, 20uH 2.5-9J at 500-950V output. 2.5lb (1.13kg)
! MK106-20 units: 6W, 40uH, 40uH 5-18J at 500-950V output. 2.8lb (1.26kg)
! 12VDC 1.5A input (charging)
! 12VDC 0.3A input (regulating)
! 0-9J at 0-950V output
! 4.00" x 6.00" x 1.50" (refer to attached DWG #A1964)
CONTROL I/O PINOUT (Amphenol #17D-DE-9P, 9pin Dsub connector)
1) 12VDC 1.2A input positive.
2) 12VDC negative (return). Also used as trigger return.
3) Trigger input. 10Kohm input resistance. Requires 10-13 volt amplitude, 100uS pulsewidth.
4) Charge indication output. 12V signal via a 22Kohm current limiting resistor indicates that the
PFN is not fully charged. The laser is ready to fire when this signal goes to 0 volts. 200mA sink.
5) Program voltage input: 10Kohm potentiometer - CW.
6) Program voltage input: 10Kohm potentiometer - WIPER.
7) Program voltage input: 10Kohm potentiometer - CCW.
8) Not used.
9) Not used.
WARNING: A 10Kohm potentiometer must be connected to pins# 5,6,7 before power is
applied to pin #1. Otherwise, damage to the unit will result!
Operating Manual Page #2

HIGH VOLTAGE PINOUT (ITT-Cannon #DEM-5WIS, Combo Dsub
connector with HV pin: ITT-Cannon #DM51155)
A1) HV OUTPUT. 0-1000 volt high voltage output to flashlamp anode (positive)
1) TRIGGER + 300V 100mS pulse to trigger transformer for lamp ionization.
2) OUTPUT RETURN Common return for pins #A1 and 1.
4. Trigger Module
! Mounts directly to MK series lasers.
! 10KV pulsed output to ionize flashlamp (hard trigger).
INSTALLATION
1. Remove power supply, laser, trigger module, and hand controller from the packing material.
Carefully unwrap each item and inspect for damage. Please contact Kigre, Inc. immediately if
any damage is suspected.
2. Connect the laser head to the trigger module. Align the three pins and gently push together
until secure. Mount laser head as desired.
3. Connect the trigger module to the HV power supply (unit with PFN). Align the plastic
connector, push in and turn to secure.
4. Connect the hand controller to the HV power supply. Align the 9pin Dsub connector and push
to secure. Refer to the pinout information above when not using the Kigre hand controller.
5. Connect the wall mount transformer to the hand controller. The transformer operates only
from 120 volts AC (contact the factory for special AC voltage requirements). Plug the
transformer into a 120VAC outlet. Less than two (2) amps are required, so most outlet types are
acceptable.

OPERATION
1. Start at a lower energy setting until you are familiar with the unit's operation. Adjust the HV
ADJ adjustment knob on the hand controller fully to the left (CCW) to begin.
2. Turn the toggle switch on the hand controller up to enable the high voltage power supply. The
green indicator will light after the PFN is fully charged.
3. Momentarily press the fire button on the hand controller to fire the laser.
WARNING: A sufficient bleed time of at least three (3) minutes should be allowed before
handling and high voltage components or connections!
MAINTENANCE
! No scheduled maintenance is required.
! Failure symptoms should be identified to the module if possible.
! The factory will repair units or sub-assemblies at the prevailing labor and material rates.
Please ensure that a complete description is given of all symptoms and events leading to
failure. This may reduce repair time.
