Tsunami DANGER: INVISIBLE LASER RADIATION Operating the laser with the cover off may expose people to high voltages and high levels of radiation. It also increases the rate of optical surface contamination. Therefore, operating the laser with the cover off is not recommended. The alignment procedures in this manual require internal adjustments while the laser is operating. The interlock can be defeated to allow this. When the cover is removed and access to the pump beam is required, raise the red shutter lever to defeat the interlock and hold the shutter open. In this position, the red lever clearly shows the defeat and prevents cover installation until the shutter lever is lowered to the closed position. Maintenance Required to Keep this Laser Product in Compliance with Center for Devices and Radiological Health (CDRH) Regulations This section presents the maintenance required to keep this laser product in compliance with CDRH Regulations. This laser product complies with Title 21 of the United States Code of Federal Regulations, Chapter 1, Subchapter J, Parts 1040.10 and 1040.11, as applicable. To maintain compliance, verify the operation of all features listed below, either annually or whenever the product has been subjected to adverse environmental conditions (e.g., fire, flood, mechanical shock, -- spilled solvents). This maintenance is to be performed by the user, as outlined below. 1. VeriQ that removing the laser head cover closes the laser shutter. 2. Verlfy that, when the cover interlock is defeated, the defeat mechanism is clearly visible and prevents installation of the cover until disengaged. 3. Verlfy that all labels listed in Figure 2-4: Tsunami Radiation Control Drawing are present and firmly affixed.
