When FPM reading is displayed but unit is not flashing,
flash tube may need to be replaced.
1. Unplug line cord from power line. Turn power switch
OFF. Wait a few minutes until stroboscope is cool
before replacing flash tube.
2. Remove protective window by removing the 4 screws.
3. Use a rag and pull the tube out of its socket by rocking
it slightly up and down. Do not use bare hands to
remove tube, it may break and cause injury.
4. Insert new tube using the technique mentioned above.
Make sure that the tube is placed properly in the socket
otherwise it will touch the reflector. Tube should be set
