Checking the Instrument Battery Power Supply
To check the power supply in the Spectra Precision FOCUS 35 Total Station battery using the built in
battery gauge, press the button on the side of the battery:
When you press the button, four LEDs on the battery show the power level. Each LED corresponds to
a power level of 25 % so that when the power level is at 100 %, all four LEDs are lit. If the battery is
completely discharged, all LEDs are unlit.
When the button is pushed and all the LEDs flash, the battery needs to be reconditioned in the
battery charger.
When the battery capacity is between 0 and 10 % one LED is flashing. A battery that has a flashing
LED might not be able to start the instrument. If started, with a battery that has a flashing LED, the
operating time will be between 5 and 15 minutes.
Charging the Instrument and the Radio Batteries
The batteries are supplied partially charged. Charge the batteries completely before using it for the
first time.
