Enabling/Disabling HD Intercom
Go in the configuration menu to change this setting.
HD Intercom enhances the two-way intercom audio from normal quality to HD quality. HD Intercom will become temporarily disabled when you enter into a multi-way intercom. If this feature is disabled, the two-way intercom audio will change to normal quality.
The intercom distance of HD Intercom is relatively shorter than that of normal intercom.
