CAUTION! The transmitting element in some versions of the Pure Digital Fiber-

link transceiver unit is a solid-state Laser Diode located in the optical connec-

tor on the unit. This device emits invisible infrared electromagnetic radiation

which can be harmful to human eyes. The radiation from this optical connector,

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.
