The actuating elements are normally concealed behind a control panel door, and the door is so constructed that portions thereof define a plurality of deflectable keys any one of which may be depressed to engage and operate an underlying tuning element. The door, including the keys, may be moved to open position to accommodate presetting of desired frequency channels.
