The station is equipped with noise cancelling microphone. The AA705 consists of an Orange Makrolon plastic (surface) housing and a membrane film keyboard.
The station has an internal 3 Watt amplifier and the speaker volume is adjustable with switches located inside the station, for four (4) levels.
