The heater can be disabled for a given Setting Profile to reduce power consumption, but this is not recommended in most circumstances.
About this task
Disabling the heater means the SMART MIC-1 cannot clear itself of condensation or rainwater. Collected moisture will significantly reduce the microphone's sensitivity until the water evaporates. We recommend only disabling the heater if the additional power draw required by the heater would create a significant issue for your deployment.
Procedure
When editing a Setting Profile, leave the Heater On
Period and Heater Off Period blank.
