Telinga Pro6 /Fostex FR2 Problem

I have been using a Telinga Pro 6 for a few months with a Fostex FR2 
and am experiencing a really strange phenomena.

On starting the FR2 from cold and going into standby recording there 
is a rumbling noise on top of the self hiss that can be heard 
through the headphones. After 2-5 minutes this noise cuts out ( with 
a click ) and the self noise is acceptable(?). This rumbling noise 
is recorded on to audio tracks which is not great.

The first time I was aware of this noise I actually thought it was a 
generator running in the background at one of my regular sites - 
that's how bad it is.

I use the FR2 on stereo, 44.1, 16 bit and use phantom power to run 
the Pro6, which is set in the middle position. I use a Tekkeon "My 
Power Lithium" rechargeable set on 12 volts in to the DC of the FR2, 
but it also makes this noise with x8 AA rechargables in the machine 

I also have a ME67 and this doesn't create or induce this noise 
which is making me suspect the Pro6 mic / recorder combination.

However, once the noise cuts, the FR2 can be switched on and off 
with no problems. Seems ridiculous to say it but it is like the mic 
needs to warm up ?! 

Has anyone else experienced this and solved it ? Is there a problem 
with my mic or my recorder ? What do you think Klas ?
