Sound, Volumes and Speech
This intercom is capable of full duplex speech, which means two people can have a conversation
and appear to speak at the same time. Since various manufacturers of android phones, iPhones
and tablets all differ in acoustic performance, and different users may require varying levels of
volume on their own handset, it may be possible to setup some devices in full duplex mode, but
others may need to be set in half duplex mode (phone user will press to talk). This may also be
required if a phone is in a particularly noisy environment, or the intercom is located near a busy
main road with high levels of traffic noise.
