Flashlamp Inspection/Replacement Procedure
Before replacing the flashlamps, always record the flashlamp pulse count on the Service and
Repair Report along with the performance data of System Check. Note the location of the red
spot on each flashlamp end. This indicates the anode or “+” electrode of the lamp.

1. Drain the water.
2. Remove the fiber block.
3. Carefully remove the flashlamp collars from the lamps.
CAUTION: Do not handle the flashlamps with bare fingers. Skin oils can damage
the quartz envelope of the lamp. Always use finger cots or cotton gloves
4. Remove the old lamps, bottom lamp first (allowing the head to drain and reduces drip
over the optic), noting the correct position of the flashlamp anode.
5. Clean the new lamps with methanol before installing.
6. Inspect and replace O-rings if necessary.
7. Inspect and clean rod or resonator optics if any water dripped on them during
disassembly.
8. Reverse steps 3–4 of this section to install the new flashlamps.
9. Reset the appropriate lamp and rod counters as follows:
9.1
Enter Testall, and then press <space> to prompt the menu screen.
9.2 Press ‘w’ to set to the appropriate wavelength. Set to “0” for the PDL or “1” for
the YAG laser.
NOTE: If replacing both sets of flashlamps, perform steps 9.3–9.4
at both wavelength settings.
9.3 Press lowercase ‘q’ on the computer keyboard. Press uppercase ‘Z’ on the
computer keyboard. This resets the flashlamp counter to zero.
9.4 Press uppercase ‘Q’ on the computer keyboard. Press uppercase letter ‘Z’ on the
computer keyboard. This resets the rod counter to zero.
