Andy I thought for sure that I read somewhere that you were supposed to REMOVE internal batteries from the Portable when connecting to an external power source(?) .. It may be that it was never intended to "charge" batteries at all. That might explain the high temps. Curt - 95


Yes if the batteries are not rechargable.

The manual is clear on this - "The battery type must be set under the settings menu. Never use disposable batteries when the battery type is set to “rechargeable”."

There is no requirement to remove non-rechargeable batteries when connected to an external power source as long as the correct battery type has been selected in the menu!
