Check and clean
Inspection and Cleaning Describe how to inspect for dirt and damage. It also describes how to clean the exterior or

maintenance can prevent instrument failure and increase its reliability.
Preventive maintenance includes visual inspection and cleaning of the instrument, and maintaining general care while
operating the instrument.
The frequency with which maintenance is performed depends on the severity of the environment in which the
instrument is used. The proper time to perform preventive maintenance is before instrument tuning.

swab dampened with a 75% isopropyl alcohol solution. Use a cotton swab to clean up the space around the controls
and connectors. Do not use abrasives on any part of the case that could damage the case.
Clean the On/Standby switch with a clean towel dampened with deionized water. Do not spray or wet the switch itself.
