PocketWizard TT5 & AC9 Problems

am using 2x TT5 with AC9 and AC3. It works on and off.

I have cero in on the TT5 & AC9 on the PCB WL X1600. The green ready light in the back panel of the X1600 and the red dump light alternate from green to red. When that happens light stops working.

Fix…..

1. Open and close battery compartment door

2. 2. Disconnect & reconnect AC9 from TT5

3. 3. Disconnect & reconnect telephone cable connection of AC9 to X1600

After repeating this several time eventually the ready light stays on steady and

X1600t starts to work normal with control of power settings from the camera.

When I turn everything off and on again I may have to do all of above to get it to work again.

Anybody encountered this problem?
