Warning: Connecting the CM49 to the wrong AC voltage may 
destroy the unit and cause fire and/or electric shock.

Replacing Fuses

The fuse protecting the primary circuit is located outside the PSU. 
Unscrew the black fuse cover to open the fuse compartment. 
Replace the fuse with a new fuse of the same type (T 500 mA for 
115V; 250 mA for 230V)

 

 and close the fuse compartment lid.

 

AC Power Connector

If you are using the microphone in a different country, you may 
need to connect the unit to a power outlet that does not match the 
power connector on the supplied power cable. Purchase a matching 
power cable locally that complies with IEC and local safety 
standards and has a power connector with a chassis ground pin. 
While in the same area, use this “local“ power cable only.

Shutdown and storage

Before switching off the microphone or disconnecting cables, reduce 
the volume of the connected equipment. Only then should the PSU 
be switched off.

Disconnect the cables. When disconnecting a cable, always pull only 
on the connector housing and not the cable itself.

When the microphone is not in use, it should not be allowed to 
remain on the stand gathering dust.

A microphone which is unused for a prolonged period should be 
stored in a cool, dry place and protected from dust.
