Voice Communication Setting
Volume settings have been preset by the
manufacturer. The preset position is shown
on picture 5. If changes are required these
can easily be made by using the trimmers
accordingly. As the system works as a
phone the transmission may result in a voice
delay, however, the system is fitted with a circuit for echo attenuation which can also be
trimmed. The volume level is set such that the microphone will automatically switch off so
that the voice does not result in an echo, see picture 5.
