摘要

An adjusting wheel (3) at the top controls volume loudness. Below a loudspeaker there is a large display panel (1), below which there is a flashing symbol to indicate an empty battery. There are also large on- (5) and off- (7) keys. When the on-key is activated, 'select' stays on the display panel. When the off-key is activated, 'end' stays on the display panel, which has large number keys.
