Generally, no skin surface preparation is required; however, for
guaranteed stability over very dry or hairy areas, clean the target
site with an alcohol wipe or apply a tiny dab of electrode gel to each
electrode. Be careful to avoid applying the electrode gel to the skin
between electrodes, which could interfere with the signals.

For measuring EMG activity over specific muscle sites which are
not suitably monitored by the triangular configuration, or where a
wide placement is required, an extender cable can be used.
Extender Cable (T8720M): Thought Technology's 450mm
extender cable can be inserted directly into the sensor head (figure
3), being careful to align the alignment dot on the cable connector
with the groove on the sensor head.

When an extender cable is used, Disposable Uni-Gel Electrodes
(T3425) are snapped in the three electrode buttons. (See figures 2
and 3).
