For EMC no testing performed. CE marking based on
careful selection of parts, including USB protection
IC, as well as special filters to reduce noise from
microprocessor (8MHz) and DC/DC converter
(200kHz). Due to the low volume of production,
testing is not warranted.

Software upgrade for the following:
 Correct setting of T-wave amplitude during Auto Pacing
mode (previous software set this to 0.0mV, should be 0.2mV)
 Correct mode selection (due to addition of ANSI/AAMI
exponential waveform in the main function list, some
automated features selected the incorrect mode).
Software upgrade for the following:

Added functions for ANSI/AAMI EC 13
Software upgrade for the following:
 Reduction in streaming interruptions
 Software controlled calibration procedure
 Added new software functions for IEC 60601-2-27:2011
(heart rate testing)
 Updated software functions to better suit IEC 60601-2-51
