13 Schematic Diagram
13.1. For Schematic Diagram
13.1.1. Base Unit (Schematic Diagram (Base Unit_Main))
Notes:
1. DC voltage measurements are taken with voltmeter from the negative voltage line.
2. The schematic diagrams may be modified at any time with the development of new technology.
13.1.1.1. Microphone Input Level (Base Unit)
Adjust the signal level to -47 dBm (11 mVp-p) with no load.
Then input the signal to MIP and MIN of the base unit through PQLT3E3A-M.
13.1.1.2. Acoustic Testing Mode
13.1.2. Handset (Schematic Diagram (Handset_Main))
Notes:
1. DC voltage measurements are taken with an oscilloscope or a tester with a ground.
2. The schematic diagrams may be modified at any time with the development of new technology.
13.1.2.1. Microphone Input Level (Handset)
