6.1 Maintenance

6.1.1 Instrument Batteries

The ORBISPHERE 3650 instrument operates on battery power (two standard C-type cells). If battery power should drop, a LO BAT warning message appears in the instrument LCD's top-left corner.

To install the batteries, unscrew the battery cap (on the right side of the instrument) with a coin or flat screwdriver, place the cells lengthwise into the battery compartment (positive end first), and then replace the cap. Refer to the diagram on the back of the instrument.

Rechargeable nickel-cadmium batteries may be used - expect about 40 hours of autonomy. Alkaline batteries provide the longest continuous use though mercury-free batteries are available that present less of a disposal problem.

Make sure that a fully charged (or fresh) set is installed before switching on the instrument.
