• The laser is enabled by pressing the gray button close to the optical

output connector on the front panel of the module. The laser is on

when the green LED on the front panel of the instrument is lit.

• The use of the instruments with this product will increase the

hazard to your eyes.

• The laser module has built-in safety circuitry which will disable the

optical output in the case of a fault condition.

• Refer servicing

only

to qualified and authorized personnel.
