(1) For the exclusive use of the Technical Support Service
(2) An earphone with a 150 ohm impedance can be directly connected to EAR+ and EAR–
(3) On this pin a maximum of 47nF bypass capacitor is allowed.
(4) When activating the Easy camera these pins will not be available for other use
(5) This output requires an external circuit to connect it to a serial port.
