SAFETY PRECAUTIONS
WARNING: Avoid personal injury and product damage by complying with the following important
operating and maintenance instructions.
Avoid Electric Shock
WARNING: To reduce the risk of an electric shock, perform only the instructions that are included in
this instruction manual. Refer all servicing to a qualified service technician.
Do not apply power to the TX until all components have been installed and all of the wiring has
been properly terminated. Failure to do so may result in damage to the product and this will void the
manufacturer’s warranty.
Do not attempt to terminate, change or un-install any of the wiring without first switching off the unit
and unplugging the AC power cord from the TX. Be sure to switch off the power at the outlet and the
TX prior to disconnecting or unplugging the power cords from the unit.
The voltage supplied must be at the recommended VAC, otherwise the TX could suffer irreparable
damage and subsequent invalidation of the warranty.
Note:
•Do not connect the TX to the power if the power cord is damaged
•Do not cut the AC power cords
Servicing
WARNING: Avoid electric shock! Opening or removing the cover may expose you to dangerous
voltages. Do not open the cover of this product and attempt service unless instructed to do so in the
operating instructions. Refer all servicing to qualified personnel only.

1.6 Troubleshooting
1. Q. The LED indicator for Power A or Power B is flashing?
A. Check the power cord inputs and ensure the switch on the power outlet along with the device is
switched on.
2. Q. The LED indicator for SYS-WAR is off.
A. Check the laser output power using a Fibre Power Meter, this indicates a lower than nominal output.
