output at the end of a stimulation protocol so as to minimise the chance of any inadvertent stimulation of
the patient.
Resetting & Re-enabling After Output Limit Error
When an enabled output limit is exceeded the stimulator output is automatically disabled and the amber
warning LED illuminates. In this state the stimulator cannot be autozeroed or re-enabled until the orange
toggle switch is transiently pushed downwards – resetting the DS5. This action extinguishes the amber
warning LED and prompts the user to autozero the input. Once autozeroed it is possible to once again re-
enable the output by transiently pushing the toggle switch upwards.
Terminating a Stimulation Protocol
Once a stimulation protocol has been completed, the output enable toggle switch should be pushed
transiently downwards to disable the output and prevent any inadvertent stimulation of the subject while
other equipment is adjusted or electrodes are re-positioned. To start a new protocol it will be necessary to
autozero the voltage input and re-enable the output as detailed above.
If any errors are reported during the actions above, please discontinue use of the DS5 and
contact your local Digitimer representative for further technical advice, advising them of the
serial number of the stimulator and the content of any error messages displayed.
