## Questions & Answers

**Q: Es contra agua?**
A: La placa de circuito está envuelta con una funda termorretráctil que tiene cierto efecto impermeable, pero no es adecuada para trabajar en el agua durante mucho tiempo. Si desea que logre un efecto impermeable muy bueno, se recomienda que aplique pegamento impermeable en la placa de circuito.
The circuit board is wrapped with a heat-shrinkable sleeve which has a certain waterproof effect, but it is not suitable for working in water for a long time. If you want it to achieve a very good waterproof effect, it is recommended that you apply waterproof glue on the circuit board.

**Q: I think i installed it correctly but i still need to keep the button on my remote pressed to keep the lights on. am i missing something?**
A: because when you press and release the button on the remote, it cannot hold a fixed state of the output. so it can not make the RC switch to keep a fixed status.
please use a switch on your remote to control the RC switch

**Q: Can i plug 2 of these in a dx5 spektrum radio i tring but only one is working the other two i brought brand new just keeps flashing.tried  2-3ch**
A: You can plug multiple RC switches on the receiver at the same time, they can work properly.
I'm not sure how you connected it. 
Please send an email including some pictures of wiring to our customer service.  they will solve your problem.

**Q: Want a remote start for tmaxx by shorting out switch of ez-start1 and hooking up aux to the (+) power lead of 7.4v 1.8ah battery.  possible?  4a?**
A: The switch is designed to use the aux channel on your transmitter for what ever you want to turn off/on. I use this to run lights but I see no reason why it couldn`t be adapted to turn your remote start on/off? Go for it!
