And 2 Q:
Why the default voice volume is so little, and the voice is OK when I turned it to the max ?(HF is using.)
Answer -
You did not give me the model number for the Nokia phone.
You can download the owners manual yourself from the Nokia web pages. It has detailed description of all the specifications and features.
Default level is always kept on the low side for safety of the listener; you can reset it to your own desires.
SWC usually means software code, but don't do anything until you give me the model number and your country of use.
Thanks,
Cleggssn
Answer Well, you have audio outs for both left and right from the pop-port. These are analog audio signals that can be used to drive the input of an audio amplifier.
If the level is too low, you may need a booster amp or preamp; or you may be going into a line input level whereas you should be going into a mic level input.
