Safety Symbols caution C A U T I O N caution The warning sign denotes a life-threatening hazard. It calls attention to a W A R N I N G procedure which, if not correctly performed or adhered to, could result in injury or loss of life.
General Safety Considerations Before this instrument is switched on , make sure it has been properly W A R N I N G grounded through the protective conductor of the ac power cable to a socket outlet provided with protective earth contact. Any interruption of the protective (grounding) conductor, inside or outside the instrument, or disconnection of the protective earth terminal can result in personal injury.

The Instrument at a Glance Lightwave Connector Care Cleaning lightwave adapters Equipment N O T E As noted in a previous caution statement, the foam swabs can leave lmy deposits. These deposits are very thin however, and the risk of other contamination buildup on the inside of adapters greatly outweighs the risk of contamination of foam swab deposits left from cleaning the inside of adapters.

The optical channel calibration accuracy is heavily dependent on the accuracy to which you know the optical source power. For best results, measure the optical source power with an optical power meter such as the HP 8153A and use precision optical connectors. In addition, proper connector cleaning procedures are essential to obtaining an accurate calibration.
