Electromagnetic interference can still occur in the home health care environment as
control over the EMC environment cannot be guaranteed. An interference event can be
recognized by gaps in G6 readings or gross inaccuracies. The user is encouraged to try
to mitigate these effects by one of the following measures:
• If the G6 reading changes by 30% or more in 5 minutes and the change does
not reflect symptoms or recent actions, take a meter reading. Compare the two
readings and contact Technical Support if they do not follow the 30/30 rule. The
30/30 rule is the following: If the meter shows less than 70 mg/dL, CGM should
read within ± 30 points. If the meter shows 70 mg/dL and above, the CGM should
read ± 30%. Example: a 202 mg/dL sensor reading and a 188 mg/dL glucose
meter value = a 7% difference (this is still considered accurate). If a reading is
outside of the 30/30 rule, if you want, calibrate again to more closely align your
CGM and meter.
• If display device misses 20 minutes of sensor glucose data (4 readings), the Signal
Loss error displays. To resolve, see Chapter 14 Troubleshooting.
• If display device shows the loading screen unexpectedly and does not display the
trend screen within 3 minutes, contact Technical Support. For more information,
see Chapter 14 Troubleshooting.
• If your receiver touch panel does not work for 6 minutes, contact Technical
Support.
