DANGER! The transmitting element in the Pure Digital Fiberlink 7222, 7224 and
7226 transmitter units contain solid state Laser Diodes located within the
optical connectors. These lasers emit invisible infrared electromagnetic
radiation which can be harmful to human eyes. The radiation from these optical
connectors, if viewed at close range without a fiber optic cable connected to
the optical connector, may be of sufficient intensity to cause instantaneous
damage to the retina of the eye. Direct viewing of this radiation should be avoided
at all times.
