Figure 3-6 Battery Switch on Bottom Left of the Monitor
This switch is designed to remove the batteries from the circuit
during shipment and recessed to prevent inadvertent contact from
changing its position. There are a few active components on the
options B and C battery board used to switch the battery V+ lines
and communication line to host with a single switch. These signals
are communicated to the power supply MCU which control battery
charging and front screen icon indications. The battery switch has
symbols to show when to turn the switch on and off. Turn the switch
off for shipping and service (refer to
Figure 3-7 ). Turn the switch to
on for regular operation (refer to Figure 3-8 ).
