Tones .....what a shame you've now run out of time ...

you will not have time to follow the instructions that are posted in one of my earlier posts..yes they were in german  but your supposed to be able to read that ?

the translation is from babel fish is

CARE In order to receive the maximum effect of the equipment, we recommend, to store the area audio Animator once in the month for some hours (best over night) in the refrigerator (optimal temperature + 3° to +8° Celsius) a putting you the space.

It means in english

that if the unit is not working as expected it requires reactivation/refeshing  over night in a fridge  between the following temperatures +3 +8 deg C.

this passage is on the instructions sheet pdf  on the web site I provided a link for .... and in one of my earlier post

these instruction were provided to me by word of mouth by the dealer ....and I imagine are on the printed sheet that came with the unit. 

Still you'll be able to honestly say you tried the unit but it had no effect in your system .....and hide the fact that didn't bother to  follow the makers instructions. You'll be fine as long as nobody else knows......but if the cat gets out the bag

[this is an equivalent  hypothetical example ]

Bit like borrowing a cable ...from a dealer taking it home and connecting it to an amp  but never switch the selector switch over to it ....you can  safely say it made no difference!   your not telling porkies... as the cable sounded no different to the one you had in previously ....   but is it a correct response ?
