Operation
1. Set the power switch on the rear of the master and slave units to the on (I) position. The power
indicators will flash indicating that the units are in standby
*
.
2. Push the on/off button on the front of the master and slave units
*
. The power indicators will
become continuously lit. The Magstim Bistim² system will start an initialisation sequence during
which the armed indicator
will flash three times and LED’s in the user interface will light
sequentially.
Once the initialisation sequence is complete, the coil indicator and disarmed indicator LED’s will
be lit and the output display will read 30% on the first line, 30% on the second line and 10ms on
the third line.
Note:
During the initialisation sequence, the operator must check that all LED’s are lit. If they do
not, the items must not be used and should be returned to The Magstim Company Limited for
servicing and repair.
3. Use the output control on the master unit UI to adjust the power level or the inter-pulse spacing to
the desired setting
*
. Rotating the control clockwise increases the power level, rotating anti-
clockwise decreases the power level.
4. Depress the output control to toggle the value being adjusted between the master power output,
the slave power output and the inter-pulse spacing
*
.
The inter-pulse spacing range can be change between 0-999ms and 0-99.9ms, when adjusting
the inter-pulse spacing, rotating the control knob on the clockwise several times until the display
shows the maximum inter-pulse spacing (999ms or 99.9ms). Press and hold the stop button on
the user interface and rotate the control knob clockwise at the same time. The display should
revert to either 1.0ms or 10ms. Turn off the Bistim² system and then turn on again and the default
inter-pulse time displayed should be in the new range (1.0ms or 10ms).
5. Press the run(green) button on the master unit UI to arm the Magstim Bistim²
*
. The armed
indicators of both the master and the slave system should light, and once the system is charged,
the ready indicators will also illuminate
*
.
Note:
If the system is not triggered within a minute of being armed, it will revert back to the
disarmed state and will need to be re-armed before continuing.
6. Remove the stimulating coil from the coil holder* and position the coil over the desired target.
