Maintenance
It is necessary to repair the hands-free kit if it has been damaged in any way, for example, if the housing is
damaged, if liquid or objects have penetrated the hands-free kit or if it has been exposed to rain or moisture.
Repairs are also required if the hands-free kit is not working properly or has been dropped. If smoke is produced,
or there are any unusual sounds or smells, disconnect the hands-free kit from the mains power supply
immediately. In such cases, the hands-free kit should not be used until it has been inspected by authorised service
personnel. Only have the device repaired by qualified personnel. Never open the housing of the hands-free kit.
Furthermore, the hands-free kit could be damaged upon opening and this would void your warranty.
Cleaning
Disconnect the hands-free kit from the power supply before cleaning in order to prevent hazards. Use a dry cloth
for cleaning and never use any solvent or cleaner that would corrode the plastic materials. Ensure that no liquid
enters the housing. Use a slightly damp cloth for more stubborn dirt.
