I friend of mine had to return a VT3 receiver and now has trouble matching his new receiver with his old transmitter. I took a quick look at the manual but the explanations weren't quite clear. The receiver indicated that the transmiter 1 is not available instead of on or off like the manual states (P.50 if I recall). Anybody had this happen to them already?
Stupid question, but your friend is trying to pair them while the transmitter is attached to a tank and is pressurized, right?
On and Off are the settings about whether you have a transmitter for that slot/tank (someone with 1 tank & transmitter would have tank 1 on, tank 2 & 3 off). "Not Available" is when you have a tank "on" but the receiver isn't hearing the transmitter. If you don't have a transmitter under pressure, it's not going to transmit. If you leave it at the same pressure long enough, I believe it will stop transmitting eventually as well. So trying using it on a tank, and as you try things, occasionally purge some air out to change the pressure.
Not a stupid question. My wife, friend & I hit Bonaire earlier this month. We had computers that can link with transmitters. We had enough new gear to work with & it was a new experience so when linking up the transmitters in the room didn't work, we just used out SPGs & left the transmitters at home.
We suspected that maybe it'd only work with the transmitters hooked up & pressurized, but never got around to testing it out. I looked in the VT3's manual (I've got a VT3; wife uses VT Pro, buddy Atom 1) & didn't see anything saying it had to be, but I certainly could've missed it.
My point is, it's not obvious to everyone it's got to be under pressure to transmit.
