Abstract (en)
[origin: EP0853305A2] The terminal is very small in size and is designed to run independently without mains power for weeks or more. It is intended to reproduce one to five messages many thousands of times with perfect quality. The unit is mounted on a post which stands between 50 cm and 180 cm high. The information is held within a non-volatile memory and may be replayed when a push-button is operated. A key-operated switch is provided to allow access to the memory in order to re-record the message which is replayed. The message length may be between 2 and 120 sec., but is pref. 40 sec. The message is replayed with amplification such that it can be heard at normal volume between 10 cm and 250 cm away from the device.
