MAINTENANCE AND CLEANING
The Telos Headphone Amplifier usually requires no maintenance. Please contact your
Goldmund approved dealer if any maintenance should be required.
Always turn the power OFF before cleaning your Headphone Amplifier.
To clean the external metal of the amplifier, always use a clean, soft, damp cloth. Dampen
it with water or a mild detergent solution. Avoid abrasive or harsh cleansers (e.g. products
containing sodium carbonate).
The identification plate is plated with precious metal. Simply clean it with a soft cloth,
without any chemical solution.
