Warnings
Static electricity, ESD
Static electricity may damage the product. In BeoSound 5/BeoMaster 5 there are
integrated circuits which operate with 1.8 volt, and that makes the product
extremely sensitive to static electrity.
Static-protective field service kit.
A static-protective field service kit must always be used when the product is
disassembled or modules are handled.
Follow the instructions in this Service Manual and use the ESD-mat for both old

Please note:
When mains voltage on the product is required, remove the connection between
the product and the ESD-mat.
The chassis or modules must always be connected to the static-protective field
service kit or placed in an ESD-proof bag.
