Perform this required modification to avoid problems such as low-level audio signals or too loud and distorted voice signals being emitted from the speaker. Refer to the SC20-460 boards instructio

23、n manual for details.3. Change the time constant in conjunction with the transmit audio level and receive audio level. Replace R1 with a 39k component, R3 with a 330k component and C1 with a 1000pF component in conjunction with the receive audio level. Replace R2 with a 39k component in conjunction

24、with the transmit audio level.Note: Perform this required modification to avoid problems such as low-level audio signals or too loud and distorted voice signals being emitted from the speaker. Refer to the SC20-460 boards instruction manual for details.4. Wrap the SC20-460 board with the cloth sheet
