Cleaning Instructions
Clean the GB1400 often enough to prevent dust and dirt from accumulating. Dirt
acts as a thermal insulator, preventing effective heat dissipation, and can also
provide high-resistance leakage paths between conductors or components in a
humid environment.
Cleaning the Exterior
Clean the dust from the outside of the instrument with a soft, clean cloth or small
brush. A brush is especially useful for removing dust from around the buttons
and connectors. Remove hardened dirt with a soft cloth dampened with a mild
detergent and water solution. Do not use abrasive cleaners.
Cleaning the CRT
Clean the light filter and CRT face with a soft, lint-free cloth dampened with
denatured alcohol. Do not use abrasive cleaners.
Cleaning the Interior
Interior cleaning and maintenance should be performed by qualified service
personnel only.
