3. WARNINGSAND SAFETY INSTRUCTIONS
Before you begin using your ML 830 Laser or the Recharger, read these
important warnings and safety instructions. For your own safety and that of your
equipment, take note of the following:
Warnings:
The Recharger must be grounded. Connection to a non-grounded
outlet is unsafe. The Warranty covering this unit is null and void the
Recharger is connected to a non-grounded electrical outlet.
Wear safety glasses to filter out 830nm infrared energy.
Do not aim the laser beam directly into the eye(s). The lens of the human
eye can focus the 830nm wavelength beam, resulting in retinal burn and / or
vision problems.
When the Laser System is unattended, all three batteries must be
removed and stored in the safety compartment in the base of the Recharger
Unit. This compartment must be locked and the key kept by the authorized
user.
Safety Instructions:
Disconnect the power plug ( by pulling on the plug, not the cord ) under the
following circumstances:
If the power cord or plug becomes frayed or otherwise damaged.
If anything is spilled into the equipment, & see page 3.

Whenever power surges are expected, such as during thunderstorms or
power outages.
4. SETTING UP THE RECHARGER
Plug in the Recharger.Connect the main power cord to the power inlet socket
on the rear of the Recharger (Figure 1). Connect the main plug to a grounded
electrical outlet. Be sure that the electrical outlet is grounded to the main
breaker box.
Switch the unit on at the power switch. The power display meter (Figure 2)
will illuminate and read "00".

5. TESTING THE POWER OUTPUT
Connect the rechargeable battery to the ML 830 Laser probe by carefully
threading the battery onto the threaded end of the laser probe. (Be careful not
to strip the threads.) Thread the battery until resistance is felt then tighten
one-half turn. Do not over tighten.
The LED meter on the Recharger measures the laser energy output of the ML
830 Laser. There is a probe sensor (Figure 3) on the Recharger located to
the right of the LED meter for the triple diode laser probe.
Place the head of the ML 830 Laser probe into the probe sensor port and
gently hold the probe steady during testing. When testing the laser probe, note
the 'notch' on the head of the laser probe and line up the 'notch' with the
register pin in the probe sensor port (Figure 4)

Activate the laser's annular or tactile (on-off) switch (Figure 5). [The switch is
located beneath the black vinyl area on the laser probe which surrounds the entire
probe.] By gently squeezing, the switch will be activated, turning the power on.
This also activates an audible acoustic "beep" at half-second interval which
continues for 33 seconds. (Note: At the conclusion of the 33-second cycle, there
is a short continuous tone.)
Note the LED meter reading. Output is measured in milliwatts (mW). The meter
should read 90mW(+/-10%).

6. CHARGING THE BATTERIES
Carefully unscrew the battery from the laser probe unit (Figure 6),
Carefully thread the battery onto one of the battery mounts (Figure 7), but only
until finger tight.

Batteries should each be charged at least twelve (12) hours before initial use or after long 
periods of nonuse.
NOTE:

Note the Illuminated Indicator lights on the left of the battery mount
The "CHARGE"Indicator Illuminates when the battery is being charged.
If the battery is left attached to the battery mount, the battery will continue to be
charged at low current. 100% capacity will be reached after 10 hours of
charging.
NOTE:
If a fully charged battery is removed from the battery mount and then replaced, the
"CHARGE" light will illuminate for a short period of time. Likewise, switching OFF the
Recharger briefly, with the battery affixed, then switching the Recharger on again will
cause the "CHARGE" light to illuminate for a short time.

7. OPERATINGTHE LASER
Warning: Do not aim the laser beam directly into the eye(s). The lens of the
eye can focus the 830nm wavelength beam, resulting in retinal burn and / or
vision problems. Wear the safety glasses provided with the unit during use.
Automatic laser activation cycle is 33 seconds. This safety activation
mechanism is built into the unit to ensure the highest level of safety for the end
user. During the 33-second cycle you will hear an acoustic "beep" at half-
second intervals.
One 33-second cycle administers approximately one joule of energy per diode
according to the following formula:
Energy(joule)=Mean Power(W) x Time (sec.)
Energy = 30mW x 33 sec. = 0.99 joule
Activate the black annular or tactile switch on the laser probe. (Figure 5). Once
the switch is pressed, the laser is activated one (1) 33-second cycle or until the
switch is lightly depressed again.
8. USE OF THE REMOTE INTERLOCK
MicroLight provides a remote interlock for use in those rare situations where the
operator wishes to terminate the emission of low-level laser energy when a door or
portal into the area of usage is opened. Call your Microlight dealer for assistance
on this module.
The remote interlock module, if used, requires unscrewing the battery from the laser
probe, screwing on the remote interlock onto the laser probe, and then replacing
the battery to the open end of the interlock.
Select a switch, or microswitch, that can be operated by the opening of the door
or other portal for which the interlock function is desired. The switch should be
electrically open when the portal is open and electrically closed when the portal
is closed.
Connect the switch across the two (2) conductors at the other end of the
interlock cable and mount the switch so as to be operated by the opening of the
portal as described above. The laser can then be operated when the portal is
closed and will be inoperable when the portal is open.
