26.4. RECEIVER DATA CIRCUIT
26.4.1. Circuit Operation:
Only received data pass through the low pass filter formed by R216 and C129 to be input to pin 22 of IC101, where its wave form
is adjusted.
The resulting signal is output from Pin 13 and sent to CPU directly.
is adjusted.
The resulting signal is output from Pin 13 and sent to CPU directly.
26.5. BATTERY LOW DETECTOR CIRCUIT
26.5.1. Circuit Operation:
When the battery voltage goes down less than 3.60 V. This level is detected by the inside of IC101, so its output is sent to Pin 26
of IC901.
The CPU detects this level by its Pin 26 and battery low indicator lights starts flashing.
The IC101 check the level of the battery, if this level is less than 3.3 V, the output of Pin 11 of IC101, then CPU stops working to
keep memory.
