19. AC Power Connection and Power Switch
Input 90V-260V, 50-60Hz AC, and the power consumption is less than 45VA.
20. Termination switch
When this switch is turned to ON position, one 300ohm termination resistor will be connected to
intercom line. If the intercom system is not terminated, the level of intercom line will be too high,
and the system stability will be influenced. However, only one termination point is allowed within
same intercom line. If multiple termination points are used incorrectly, the driving load will be
aggravated, and the level of intercom line will be too low.
This switch is set to ON position by factory default. Before using, you should set it to ON or OFF
