The batteries in the Carlson Surveyor are “smart batteries”, so when the battery reaches a very deep discharge state the firmware shuts down the battery and the data collector will not turn on.

Some batteries can get stuck in a “Critically low power state” and they will not accept a proper charge when installed in the Data Collector and the AC Wall charger is connected for a few hours.

Please follow the steps below to resolve this issue:

1) Install the battery pack into the Surveyor+ and drain the battery completely:
  a. Exit out of SurvCE by going into File / tap Exit / tap Yes
  b. Tap Start in the upper left / tap Settings / tap the System tab in the bottom left
  c. Scroll down and tap the Power Icon then tap the Advanced tab in the bottom left
  d. UNCHECK “Turn off device if not used for” under the “On battery power” as shown in the screenshot below.
  e. CHECK the box under “On External Power” and set it for 30minutes
  f. Then tap OK in the upper right to save your settings and tap X to return to the Today screen.
  g. Now you can unplug the unit from the AC Wall Charger and leave the screen powered on until the unit turns itself off {This may take a few hours if the unit has more then 10% of charge left}

2) After the battery is drained - Remove the battery from the unit by opening the back hatch and lifting it out

3) With the battery STILL removed - plug in the AC Wall Charger to the top of the Surveyor

4) Turn on the Surveyor and let it stay powered on and plugged in for 4 or 5 minutes without a battery pack installed

5) With the data collector still Powered on and Plugged into the wall charger, the battery should then be installed and if the battery was completely drained you would need to leave it plugged in for 5 or 6 hours to fully recharge to 100%

6) You can Repeat Step # 1a to 1d then CHECK the “On Battery Power” box and set it to 5 minutes then tap OK to save these settings.
