• Optical grade cleaning cotton swabs
• Canned air
• Isopropyl alcohol
• Fiberscope or similar if available
• Lint-free tissue or cleaning cartridges
Use only high quality cleaning supplies that are non-abrasive and leave no residue
Procedure 1. Turn the XTA-50 off (see section Turning off the XTA-50, p. 21 ) and unplug the power
