Hi Woketman,

As you already see a lot of AMT users have the same experience with the V1.2 EDT. This EDT has a 9Volt rechargable battery which will last for approx. 2 to 3 years. Normally replacement of this battery helps. Also the control of the contrast of the LCD is depending on the supply of this battery.

In the newer once we use 3 AAA NiMh cells. In the begin there was some problem with switching off to a sleepmode but thay is solved for mor then a year already.

So please if you have problems with the EDT send them back to AMT Netherlands (Bennie) and we will look at it.

Ray,
