One of thes Locus unit is bliking red led's in sequence from the battery led to the solved (right to left). I have replaced the batteries, tried system reboot (per the manual) to clear the memory. It turns off when the button is pushed. When turned on we never get any green leds no maqtter how clear the sky or number of sv's. Any ideas or suggestions aside from baseball bats, 2x4's, target practice, etc, or buying a promarkII would be appreciated.

After you did the full reset did you give it 20 minutes outdoors to sort itself out?

Try the full reset again.

If it will not go back to work it is time to contact the repair shop.

I tried the full reset several times. After I turned it on it did the same thing and it shut it's self off after 5 +/- minutes. But I'll give it another shot. I'm afraid its repair shop time.
