## Questions & Answers

**Q: Does this unit allow you to up the treble and lower the bass?**
A: This thing did nothing helpful - distorted sound - and I returned it.

**Q: will serene work w/a headset?**
A: I haven't used it with a headset, but I don't see why not as long as it has a standard phone cord. A headset works the same way as a handset, wires to the speaker and wires to the microphone are the same. It just won't work with anything cordless. It plugs into where the handset would go, and the handset or headset plugs into the unit.

**Q: what kind of battery does it need? must buy Serene Power Adapter (For UA-45 & UA-50 Phone Amplifiers)?**
A: 9V battery works w/ UA-45

**Q: I have a magic jack and it will only power 3 phones. can i use this to amplify the line voltage and power more than 3 phones?**
A: My understanding is that this is only a volume amplifier for the one phone where it is connected between the phone and the headset.  It works great for that.
