Curlin 6000 Infusion Pump

I am having a problem and wondered if anyone else has experienced this; if so, how did you work around this.

I charge the pump on AC. I have charged it with/without batteries in place. I use the pump as an ambulatory pump.

When I boot the pump the power level will display "full".

When I prime the pump I get a low C battery display; but if I turn the pump off and reboot after priming I get a power level display of "full".

I am unable to use one set of batteries for two infusions (each 6 hours)

I have a call in to the company; but have not received a reply. So much for service after the sale!

Thanks in advance for any assistance!
I always check the internet when something just won't work to see if anything's wrong. Is this your device? Well, I was able to find the manual too, but some problem with it not linking to the manual once I put it on AN?!http://www.ivteam.com/moog-fda-iv-pump-alert/
