If the battery in your Surveyor2 will not take a charge or the unit will not turn on even after charging for a few hours
you can try the steps below:
#1) Make sure you are using the correct charger for the product. It should provide a 12V output at 18 - 20 watts (1500 -
1700 mA). Some chargers for other products may be similar, but not provide the correct output. Even chargers for our own
older product models may provide the correct voltage, but not enough wattage (amperage) to fully charge the battery
within a reasonable amount of time.
#2) Perform a Hard Reset by pressing and holding the Power button for a full count of 20 seconds. If the unit was
running on external power before, the screen will flash off and on two or three times while holding the Power button,
and even a blue screen with sliders will appear. Keep holding the Power even until the blue screen disappears, and then
release. You then may need to hold the Power button again for 2 - 3 seconds before the unit will start booting.
#3) A battery that has been severely depleted will enter a "recovery mode" which can take 2 to 4 hours on external power
before it will even begin to show a change in charge status and then operate (even briefly) without an external power
source. When a battery is in such a condition, it is recommended to leave external power attached over night or weekend
(as is usually recommended for between work days) to ensure full charge the next work day.
To best avoid such a condition in the future, charge every night and weekend.
For short term storage (such as less than 2 weeks), Tap File / Exit / Yes to exit out of SurvCE then hold the Power
button for a few seconds and release it when you see the pop-up menu. Tap "Power Off" from the menu then tap OK.
For long term storage of any unit (such as more than 2 weeks), Tap File / Exit / Yes to exit out of SurvCE then charge
the battery to full then remove the battery pack store it separately.
