Introduction
The height mark allows you to hook the measure tape onto it
so you can unroll the tape down to the survey mark and read
the slant height measurement directly on the tape.
Special Button
Combinations
With the ProMark 800 OFF, pressing the Power, Log and
Scroll buttons simultaneously for a few seconds will
restore all the factory settings. Always use this
combination after changing the radio module. This allows
the receiver to recognize the new module.
With the ProMark 800 OFF and a USB key connected,
pressing the Power and Scroll buttons simultaneously for
a few seconds will cause the ProMark 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 10 MBytes of free memory, before starting the
upgrade.
These button combinations are summarized in the table
below:
