6. Electrodes are the weak link in the EMG measurement chain. Lack of proper attention to electrode
quality or site preparation is by far the most common cause of inferior recordings.
7. It may take up to 5 minutes for disposable electrodes to fully stabilize electrically once applied to the
skin. If extremely critical or precise measurements are intended, the electrodes should be applied
several minutes in advance of the recording.
8. Cable motion artifact, if present, can be minimized by immobilizing the electrode lead wires near the
snap end of the cable. Taping or wrapping the wires to the subject may prove helpful when very
dynamic movements are being measured.
9. When attaching the cable set to the electrodes, always connect the Reference lead first. This permits
any difference in static electricity between the subject and the instrument to be safely discharged.
When attaching EMG leads, prevent lead snaps that are not yet attached to
electrodes from coming into accidental contact with other conductive objects.
This will avoid a potential shock hazard. A simple way to ensure this with
disposable electrodes is to first attach electrodes to all snaps, unpeel the
adhesive cover and apply the electrodes to the patient.

1. Active Electrode Leads
Each active electrode lead has a built in pre-amplifier powered from the TeleMyo 2400T. In addition, any
of these EMG leads can be separately unplugged or replaced. The pre-amplifier electronics are contained
in the removable lead and can be in either single (standard) or a double differential configuration. When
connecting each lead to the TeleMyo 2400T transmitter, match the numbered cable to the numbered
receptacle.
It is important to switch the TeleMyo 2400T to the "0" position before
connecting or disconnecting any active lead. Failure to do so could
damage the lead electronics.
It is also important to have all leads detached from the patient while the
device is being charged. Failure to do so may subject the patient to an
unwanted electric shock.
Finally, it is important to inactivate all input leads that are not being
used. For active leads this can be done by placing back-to-back
electrodes between the lead snaps. Alternately, unplug the lead and
place the rubber protective cover over the exposed input connector.
