Hi all,

We are having a connectivity issue with our TDC650 unit that is occurring while we are in the field.  We generally work long field days (10+ hours in summer) and need to swap out the battery with a second one while in the field, generally in the afternoon. We are running into a problem where the TDC650 will not provide a location after the battery has been swapped.  The unit will connect to 20+ satellites but will not provide a horizontal or vertical position and will not let us record a location. Trimble Mobile Manager will also not connect.

Our TDC650 does not have cellular service.  The problem seems to resolve when the unit is brought back inside, connected to WiFi, and synced.  However this is not possible in remote places when working long field days.  Is it possible a setting is changing when the battery is being swapped? I surely hope an internet connection is not required after a battery swap as that renders this unit almost complete useless to us in summer...

Thanks!

Hi Sam

To help the community 'detectives' offer best practice, how are you swapping the battery out please?

• Are you saving and closing your applications first then powering down the TDC650?  Or are you just removing the battery?
• What applications are you using?
• Finally what GNSS firmware are you using? You can find this out If you run the Trimble Installation Manager application - the latest is 4.35

If you can detail this you should get some informed responses, alternatively you can try contacting your local Trimble reseller who you purchased your equipment from to offer advice

Thanks Tom.  Additional information below.

• We are saving all applications and powering the unit down before performing the battery swap.  We have been following the directions provided in the manual.
• The main application we are using is TerraFlex.  Interestingly, the time on the unit is also incorrect after a battery swap so I am wondering if this problem is not restricted to the TerraFlex application.
• Unit is currently running GNSS firmware v. 4.33.  We will update to 4.35.
