## Questions & Answers

**Q: Once batteries are charged do i need to unplug charger or can i leave batteries in the charger (i don’t want to damage the batteries)**
A: I myself, remove the batteries and charge them after each performance.  After they  have completed charged, I remove them from the Charger and store them separately from the headsets.  The batteries are lithium ion and should never be overcharged as they could explode.

**Q: This comes with a master and 3 remotes.  can spare remote be used as master if master is damaged?**
A: The battery went dead on the master unit during a show and none of the headsets would work without it.  Fortunately, I had extra batteries for all the units and replaced them.

**Q: Does this system come with the case that's pictured?**
A: Yes a small bag is included with the package

**Q: If I buy the 4 singles, they will be able to speak and hear all together at the same time? do I need a base?**
A: You need the base master unit.  You should buy a set of 4 so they talk to each other.  I bought a single and could not get it to talk to the other units.
