system components

Charger

The Charger, included with the product, charges the BTS TMJOINT

probes.

The Charger can simultaneously charge all the EMG probes of the system

(6 maximum) and includes a lodging to store the receiver when not in use

for acquisition.

The EMG probes are connected to the charger using the same clips that

normally collect the EMG signal.

For correct connection simply follow the outline of the probes

shown on the base of the Charger.

At any rate, poles connected incorrectly will not recharge.
