Name	Definition location	Description
GetGain	Local	Used to query the properties Gain, GainMAX and GainMIN of the OCA object. If the query was successful, the result is output in the properties stGain, stGainMAX and stGainMIN.
SetGain	Local	Use this method to set the gain of an OCA object in dB. If the method was executed successfully, the result is output in the property stGain.
RNtfGain	Local	If the OCA object was prompted to notify changes (using the Subscription method), this method is used to read incoming notifications.
