Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by the circled numbers, which are described in detail below:
(1)
To check for electromagnetic noise near the machine, use a frequency signal monitor
constructed as shown in the schematic below:
The circuit lights the LED for every heart beat and/or disturbance that is received: in this way
it possible to determine whether there is any interference, and identify its sources.
(2)
Check the battery power level, using a tester if possible. Otherwise use a receiver or another
“reference” machine to check operation up to a distance of about 80 cm from the receiver.
Consult paragraph 11.1. “Technical notes on cardio receivers” in the Appendix.
