From the "manual":-

1. The LED blinks alternatively red and green : the batteries are
being disharged for max. 10 minutes (Refresh-Function)

2. The LED blinks green : the charge of the batteries is being
checked and afterwards being charged with a battery-sparing impulse
loading for ca. 3 minutes at a reduced charging current.

3. The LED glows continuously red : the batteries are being charged.

4. The LED continuously glows gree : Batteries are fully charged.

5. The LED blinks red : the inserted batteries are not positioned
correctly in the charging slot or are defective.

Thanks.
I have of course long ago mislaid the manual.
I did try googling for it, but didn't have any luck.
