5. Insert battery into battery receptacle and snap into place. The system will beep three
times to let you know that you're in the selected operational mode. The MyoSimulator
is now provided with power through the electrode connection and is ready for use.
6. Set the flip-switch "OPEN / CLOSE" (Fig.1, Pos.6) in the middle setting.
7. Set the flip-switch "NORMAL / CO-CONTRACTION / SAFETY CONTRACTION"
(Fig.1, Pos.4) in the "normal" setting.
8. Turn the "OPEN" control knob (Fig.1, Pos.2) to the "LOW" setting and set push-
button to "OPEN / CO-CONTRACTION". The System Electrohand opens.
9. If the Electrohand closes instead of opens, switch the two electrode plugs on the
Four Channel Processor II.
10. Set the "CLOSE" control knob (Fig.1, Pos.5) to "High" and set the push-button to
"CLOSE / SAFETY CO-CONTRACTION" (Fig.1, Pos.7). The System-Electrohand
will close quickly.
NOTE: The set signal will be available for use once the respective button has
been pressed, or when the "OPEN / CLOSE" flip-switch has been set in the
"OPEN" or "CLOSE" position.
11. Set the flip-switch "NORMAL / CO-CONTRACTION / SAFETY CO-CONTRACTION"
in the "CO-CONTRACTION / SAFETY CONTRACTION" setting.
12. Press the "CLOSE / SAFETY CO-CONTRACTION" button.
NOTE: The MyoSimulator will generate with a preset signal amplitude a short,
quick co-contraction (<80 ms) and within 2 seconds a single short, quick
contraction in either one of the 2 channels.
13. This will be followed by acoustical feedback from the buzzer and a short vibration by
the 10S17 Electric Wrist Rotator.
14. Set the "NORMAL / CO-CONTRACTION / SAFETY CONTRACTION" flip-switch
in the "NORMAL" setting.
15. Increase the signal strength on both control knobs by rotation towards "Max".
16. Pressing "OPEN / CO-CONTRACTION" or "CLOSE / SAFETY / CO-CONTRAC-
TION" will rotate the 10S17 Electric Wrist Rotator to the right or the left.
17. The changeover in the "ON / OFF" mode will occur as described in points 10 through
13.
18. Control of the hand will occur as described in points 7 through 9.
6.2 Activating a Four Channel Processor II in Second Mode for the elec-
tromotor pronation and supination of a System-Electrohand with DMC plus
Control.
1. Connect a buzzer to the Four Channel Processor II.
2. Select Safety Mode 2, inserting the red coding plug.
3. Plug the MyoSimulator's electrode cable into the Four Channel Processor II (Fig.6).
4. Attach the Electrohand to the 10S17 Electric Wrist Rotator.
