6.2 Placement of the Electrodes
For electrode placement, the skin should be cleaned with an electrode skin
preparation product to remove any oil and dirt from the skin’s surface. Using
a cotton-tipped applicator or your finger, rub the skin briskly but gently
several times with the product. This will help to reduce skin impedance and
ensure proper recording conditions.
After skin preparation, use a tissue to wipe away any residue of the skin prep
product and to dry the skin.
Then, with the electrode cables already snapped/clipped onto the disposable
electrodes, apply an adhesive electrode on each of the three electrode
placement points, the high forehead, temple (or cheek) and nape of the neck
(or right mastoid).
6.3 Placement of Insert earphones
IMPORTANT NOTES
Insert earphones can be used with in-the-ear disposable eartips or, on some
systems, with EarCups that adhere to the skin around the ear. The adapter
tips at the end of the insert earphone tubing is different for these 2 options
and only the adapter that is suited to the disposable type should be used. It
is also important to use only the disposable type (in-the-ear OR EarCup) that
is supported by your MB 11 hardware and software. Changing between in-
the-ear and EarCups without proper calibration of your device can result in
inaccurate test results due to calibration differences needed for these two
different disposables.
There is a RIGHT ear and a LEFT ear insert earphone. It is important that you
match the insert earphone to the correct ear for the results to be assigned
to the proper ear in the database.
6.3.1 Insert earphone tubing and adapters
Verify that the tubing and adapter that correspond to your chosen
disposable type are installed onto the insert earphones.
