How do you go about switching on the WA7 after adding the WA7TP to the chain? Is it switching on the WA7TP on first via the front button, and then flicking the rear switch on the WA7?
That won't work. The WA7tp will not power on unless the WA7 has already been switched on.
Or do you keep the WA7 permanently in the ON position and it turns off when you turn the WA7TP off?
This, this is what I do.
