Q: Can I use a headset with 2 2.5mm plugs?
A: Yes, you can; but, you need a connector adapter that is available from Serene Innovations.

Q: Can I amplify the handset and headset simultaneously?
A: No you can't. The UA-50 can only amplify either the handset or headset at any given time.

Q: What type of battery is used?
A: The UA-50 uses a commonly available 9V alkaline battery as power back-up. The battery is not needed as long as there is power to the ac adapter.

Q: What will happen if I don't have battery back-up during power outage?
A: UA-50 will not work. In case of emergency, you can set the "compatibility" switch to position 7 to bypass UA-50 so you can hear un-amplified sound.
