## Questions & Answers

**Q: does this need a sim card for the recording function?**
A: Yes, this voice amplifier need a TF card or U drive for the recording function. The item itself doesn't have memory to save recording data. 
Kindly be informed that it is TF card but not sim card.

Thanks

**Q: Is it possible to disable the Bluetooth so people cannot have access to the speaker while teaching?**
A: Hi, sorry to tell you that you can't disable the Bluetooth directly. However, kindly inform you that people have to manually press the button M on the speaker to switch to Bluetooth but NOT like other devices could directly be access to it. 

Thank you.

**Q: Can I set up 2 voice amplifers for a larger room and just use one mic?**
A: Hi,

This model voice amplifier comes with wired headset but not wireless, so you can't set up 2 voice amplifier with one mic. However. This voice speaker is specially designed for outdoors, so even it is 10W output powerful but it louder than the 25 watts. 

Or if you would like to choose a more powerful voice amplifier, kindly suggest you our another model S92 25W portable pa system (with handheld mic and headst mic ) or H2 30W pa system. If you are insterested in them, please click the following link for more item detailed information:

Thank you.

**Q: I teach water aerobics is everything water proof?  I need a headset I can wear while I am in the water instructing the class**
A: This wouldn’t last in the pool. It’s more water resistant. The plugs have covers to keep water out. But if you want to plug a headset in, your going to half to remove the cover and exposing the plugs. I’d say it would be fine for poolside if you can find a water proof Bluetooth headset.
