Charging Batteries
Before Use
10
The battery is housed in a battery compartment accessible
from above the ProFlex 800. The compartment door can be
opened by lifting and then turning the quarter-turn finger
screw counter-clockwise.
The battery will automatically operate as a backup power
source for the receiver if for some reason the external DC
source used is removed from the DC power input.
A slide switch is available at the bottom of the battery
compartment to set the behavior of the receiver after removal
or failure of the DC power source while the receiver is on:
• Slide switch pushed to the right: Automatic re-start. The
receiver will automatically be switched on when DC power
is restored. This is the typically the setting that should be
used with ProFlex 800 CORS.
• Slide switch pushed to the left: Manual re-start. After
power is restored, the receiver will stay off. Operator
intervention is needed to switch the receiver back on.
Use for example the tip of a pen to slide the switch to the left
or right.

Special Button Combinations

• With the ProFlex 800 OFF, pressing the Power, Log and
Scroll buttons simultaneously for a few seconds will
restore all the factory settings.
• With the ProFlex 800 OFF and a USB key connected,
pressing the Power and Scroll buttons simultaneously for
a few seconds will cause the ProFlex 800 to start a
firmware upload process. If there is no USB key
connected or the key does not contain a firmware upgrade,
then the process will abort after a few seconds.
Because data has to be decompressed on the USB key
during upgrades, the USB key must be unlocked, with at
least 100 MBytes of free memory, before starting the
upgrade.
These button combinations are summarized in the table
below:
