Part 2. Batteries and Charging

Gradiometer includes 8 standard rechargeable batteries – AA type with 2500 mAh capacity each. They
allow the device to operate for 50 hours. If only 4 similar batteries are installed the device will work for
25 hours. Time necessary for complete recharging of batteries is 4-6 hours. Regular, non-rechargeable
AA batteries can be used as well. Time of operation will be between 15 and 60 hours depending on the
manufacturer of batteries.
CAUTION! NEVER RECHARGE NON-RECHARGEABLE BATTERIES!
Need for charging is indicated by the blinking symbol ≤≤≤ in the upper right corner of the display.
Charging is done by connecting the AC or car charger to the plug on the battery compartment of the
device. Both types of adapter are included with the device.
To charge gradiometer – turn it off and plug the appropriate adapter into the battery compartment.
The device will test the level of the battery charge and display it on the screen in %. After batteries are
fully charged the device will play a sound and stop charging. The sound will continue to play every 3
minutes.
Replacing batteries. Remove 4 screws on the battery compartment, remove the batteries, and install
new ones. CAUTION! ALWAYS INSTALL SIMILAR TYPE BATTERIES FROM THE SAME BATCH! OTHERWISE
THEIR SAFETY AND LIFE OF OPERATION ARE NOT GUARANTEED!
Non-rechargeable AA batteries can be used as well. If batteries of a different capacity than the ones
used by the manufacturer are installed, level of charge indicated by the device may not be precise.
Since all batteries are magnetic, after replacing them, check balancing and alignment tuning of the
sensors.
