3.1 Temperature Threshold

This slider control is used to set the temperature threshold where the attenuation starts to be applied to the signal. The minimum is 100°C and maximum is 150°C.

The device recommended operating conditions specifies a maximum temperature of 140°C. It is recommended to set this threshold 15°C below the maximum recommended operating temperature of 140°C in order to let the feature act and keep the device within a safe temperature region. In addition, the slope must be considered when setting the threshold as the attenuation is gradually been applied as the temperature rises, it is not an instantaneous change.
