5.2 Preparing the MB 11 for use
The MB 11 unit consists of a USB interface box connected with the MB11
Classic preamplifier by a cable.
A USB cable connects the MB 11 interface box with a USB port of a mobile
or desktop computer.
The MB 11´s power is directly supplied through the computer via the USB
port. No external power supply is needed.
The insert earphones and electrode leads plug into jacks in the preamplifier
(see Figure 3).
The MB 11, like any hearing screening device, should be operated in a quiet
room, so that the screening results are not negatively influenced by outside
acoustic noises.
Electro-medical instruments with strong electromagnetic fields (e.g.
microwaves - radiotherapy devices), can influence the function of the
MB11 Classic. Therefore the use of these instruments in close proximity to
the MB11 Classic should be avoided.
The test room must be at normal temperature, usually 15
°
C / 59
°
F to 35
°
C
/ 95
°
F. If the device has been cooled down (e.g. during transport), please
wait until it has warmed up to room temperature.
