 AudioCharta® - compact system: The characteristic feature of AudioCharta compact is the smart construction, which keeps all units inside a case. All functions can be controlled by the ergonomic keyboard - the sound volume can be adjusted with a separate turning knob. The individual shaped buttons supply the needs of blind people. Combined pressing of several buttons is not necessary. The excellent integrated stereo speakers support the smooth and up-to-date synthesised voice at its best; even at a high volume level.
