TX Operation Description (Finder) Transmit Frequency : 433.92MHz Modulation Type : ASK Press Key ‘FIND’ hold for some time, the device goes into working mode. Backlight is on. And press key ‘FIND’ once again, IC4 is RF Module oscillator with 433.92MHz. IC2 is memory. IC1 is MCU and LCD display drive. Pin 9 of IC1 output data signals to RF Module and transmits out. At the same time, Pin10 of IC1 control the Q1. When pin10 is zero level, the Q1 is off, and the backlight is not working; when pin10 is one level, the Q1 is on, and the backlight is working. Without operation for 10s, the device automatically goes in stand by mode, and the LCD is not display.
