If the batteries are weak or the wrong power adapter is used, it can cause the machine not to power up.

• If you are using batteries, replace ALL of them with new six "AA" batteries.. Follow the pictures in the batteries compartment on positioning the "+" POSITIVE end of the batteries.


• If using an AC power adapter, check the rating of the adapter. The label on the adapter should list the OUTPUT as 7VDC 1.2A. The label should also indicate the "+" POSITIVE and the "-" NEGATIVE contacts of the adapter plug. The outside surface of tip at the end of the plug should be "+" POSITIVE and the inside contact should be "-" NEGATIVE. Using a wrong adapter can damage the machine internally and void the warranty. The recommended adapter for this machine is the AD30.
