Never blow air at the microphone.

 

When operating in a dusty environment, take the precautions discussed in https://convergenceinstruments.com/pdf/Dust_Issues.pdf.

 

Avoid over-discharging the battery.

• Recharge the instrument immediately if the LED indicates a low-battery condition.

• Even if the instrument is Idle all or most of the time, recharge it fully at least once every 6 months.

• When leaving the instrument idle for a long time, make sure the WiFi™periodic connection is disabled.

 

Do not store or operate the instrument at temperatures exceeding the following limits.

• -20 °C to 60 °C (-4 °F to 140 °F)

 

When using instrument outside, make sure the USB connector is facing down like in Figure 15. This way rain will not accumulate in the connector and microphone port.

 

Do not mount on a metal plate. That would drastically weaken the WiFi™signal.
