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.
