I have a Sokkia EAGL3 laser that I have been using to dig a construction site to -1% grade. Saturday I put it in its box and yesterday when I took it out and put it on its tripod, then switched it on and the screen now says ERR- 1. It's starts turning right away, sometimes fast sometime slow. Can't adjust anything so I don't know whether it is level or not and if it is set on the right grade. What does this code mean?? Thanks, Dennis
New batteries and a new internal battery and a dealer reset eventually solved the problem. Batteries weren't difficult to find, the internal battery was more of a hassle as the one it had, is not available in Europe! Dealer found a different one that works.
Hi, I have the same problem... I could replace the internal battery by myself, but what do you exactly mean with "dealer reset"? Thank you in advance for your help, billypowell
My dealer changed the battery, and he had to clear the error code. Can´t tell you how. Internal battery is not available here in Europe, and i couldn´t get someone to ship it from the States. (something to do with Lithium....) So we found a similar one here, but it´s just a little less capacity. We´ll see how long it lasts. I had it calibrated while it was at the dealer too. Good luck
