The Li-Ion batteries used in the battery packs should run at no less
than 80% capacity after 500 charging cycles. These batteries do not
need to be drained before recharging.
Power Management
Topcon’s PC-CDU software provides an interface for various
configuration, monitoring, and management functions for the
receiver.
For power management of the receiver, PC-CDU enables the power
source, enables the charging mode, and displays the current voltage
for the batteries.
1. Connect the receiver and computer. See “Connecting the Receiver
and a Computer” on page 2-20 for this procedure.
2. Once connected, click ConfigurationReceiver.
3. Select the Power Mode drop-down list to set the power source
(Figure 2-9). Current Mode displays the current power source; if
using the cradle, it will show “extbat.”
• Auto – receiver automatically selects the power source
• Mix – the batteries will discharge almost simultaneously
• Battery A – both batteries will discharge in sequence: first A,
then B, A, B, and so forth. In this case, battery B will last 1 to
2 hours longer.
• Battery B – both batteries will discharge in sequence: first B,
then A, B, A, and so forth. In this case, battery A will last 1 to
2 hours longer.
