GM-P420PCE GM-P421PCE GM-P420E GM-P420PCEG The REMOCON THROUGH function is a function that is capable of controlling such equipment as a karaoke system connected to the REMOCON THROUGH terminal by receiving the IR (infrared ray) signal at the sensor of the remote controller unit of this model. 1. REMOCON THROUGH output terminal The REMOCON THROUGH terminal and MAKE (mini DIN 4 pin) terminal at the back of the main body share the same terminal. Therefore, it is necessary to change the setup at the SERVICE MENU when the REMOCON THROUGH function is used. For the pin layout at the terminal, the 4 pin will become an output terminal and the 1-3 pins will be GNDs. REMOCON THROUGH OUTPUT TERMINAL Pin No 1 Signal name GND GND GND OUTPUT 2.

(1)Do not touch the LIVE side GND or the LIVE side GND and the ISOLATED(NEUTRAL) side GND simultaneously. If the above caution is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out. (2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or never measure with a measuring apparatus measure with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time. If the above precaution is not respected , a fuse or any parts will be broken. Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice.
