Installation and Maintenance Instructions Replacing the Flash Tube SHOCK HAZARD Strobe and HID light systems generate high voltages. Disconnect power from the strobe system and wait at least 5 minutes before opening the unit. Do not apply power to the unit while the unit is open.
Installation and Maintenance Instructions HANDLE STROBE AND HALOGEN LAMPS CAREFULLY Strobe and halogen lamps get hot enough to burn you. Always allow these devices to cool before handling them. Halogen and strobe lamps are also pressurized and if broken can result in flying glass.
Installation and Maintenance Instructions Carefully remove the flash tube from its socket by grasping the connector and lifting upwards using a slight rocking motion. DO NOT TOUCH LAMPS WITH BARE HANDS Oil deposits on the glass portion of a strobe or halogen lamp can cause the glass to fracture during use.
