Q&A: Can the IHC-200's alarm be disabled?

The IHC-200’s alarm cannot be disabled. Please understand that the maximum value of AH (Alarm High Humidity Set Value) setting can only be set up to 99%.
Because the probe of the IHC-200 is not waterproof, if the humidity reaches 100%, the probe may be damaged. The maximum value of AH can be set to 99% which is also designed to protect the probe.

The alarm buzzing is really really annoying and upsets my neighbours. There has to be a better design or a way at least to quieter it?

Sorry, at present it can only be solved by setting the alarm range to the maximum.
