OMU System and may cause injury to the user.
Throughout this manual, there are "Caution" warnings. "Caution" calls attention to a procedure or practice,
which, if ignored, may result in injury or damage to the system, system component or even the user. Do not

Safety to Equipment
When installing, replacing or using this product, observe all safety precautions during handling and operation.
Failure to comply with the safety precautions and with specific precautions described elsewhere in this manual
violates the safety standards of the design, manufacture, and intended use of this product. Axell Wireless
assumes no liability for the customer's failure to comply with these precautions. This entire manual should be
read and understood before operating or maintaining the OMU System.
Class 1 Laser
This product is equipped with class 1 lasers, as per definition in EN 60825-1.
Caution
Un-terminated optical receptacles may
emit laser radiation. Do not stare into beam
or view with optical instruments.
Optical transmitters in the opto module can emit high energy invisible laser radiation. There is a risk for
permanent damage to the eye.
Always use protective cover on all cables and connectors which are not connected. Never look straight into a
fibre cable or a connector. Consider that a fibre can carry transmission in both directions.
During handling of laser cables or connections ensure that the source is switched off. Regard all open
connectors with respect and direct them in a safe direction and never towards a reflecting surface. Reflected
laser radiation should be regarded as equally hazardous as direct radiation.
