FF9 transmitter display incorrect battery voltage

[Mick]

Hi,can some one please help me to resolve this problem;
my transmitter(futaba FF9)shows the wrong voltage value.I have repeatedly
controled the correct value(10volt) of the battery,before placing it into the TX,few minutes after use,the TX alarm goes on and it shows about 2 volt lower than the real value.

Have you tried a different battery?

Hi Nells,I did try two different battries,unfortunatly ,both of them were(I suppose) wornout.I have had a chat with one dealer near my home town and he will send a new one,of what I understood,he is quite sure that the fault was in the batteries.
Thanks for your reply.
All the best,
Mick.
