4.5 Recording test
After activating the recording test, the preselected speed and the sensitivity will be displayed. In
this state (STOP) the parameters can be modified using the appropriate keys. After the start the
first two channels will be recorded with the selected parameters. Other channels cannot be
selected. Recording is continuous and must be aborted by pressing the Start/Stop key. Quit the
test by pressing any arrow key ( , ). The next test will be displayed.
4.6 IR test (MicroSmart MC only)
After activating, test the IR interface as follows:
Arrow key ->: a test string is continuously transferred until the Start/Stop key is activated
Arrow key <-: data can be received from a remote station and be shown on the display.
Initiate data acceptance with the arrow key " <- ". The interface is set for
the receiving mode when striking this key. From this point on the operator
has 20 seconds for an entry (data transfer). Always conclude a transfer by
striking the carriage return key. Note that there is a minimum and
maximum number of transferable characters. At least two valid characters
plus carriage return must be transferred to make them show on the display.
If more than 200 characters are transferred before carriage return, a buffer
overflow will be signaled. If there is no overflow, the first 16 of the
transferred characters will appear on the display. If, after activating data
acceptance, no characters have been received within 20 seconds, an
appropriate error message will be shown.
Quit the test by pressing the Start/Stop key again.

After activating, the test results will be written out. This output supplies data on the software
contained in the unit (reference number, version number, date of preparation of the firmware),
the results of the tests carried out during power-up, and details on the connected patient lead.
