To switch between 2 options – single short closing of wet contacts.
Upon choosing the calibration option mode close wet contacts for 1
second to start calibration process.
Upon this indicator will intensely flash, and calibration process will
start. Upon successful calibration HUD-A will automatically switch to
PO2 indication mode and store the calibration coefficients in a
nonvolatile memory.

HUD-A has 2 separate independent LEDs (red and green) to connect
the device as a common dependent HUD. There indicators does not
depend either on HUD-A electronics or on the inside, and are
managed exclusively by the external dive computer.
ATTENTION! IMPORTANT!
HUD-A does not have pressure sonsor. Calibration is done
based on the assumption that ambient pressure is equal to
1,000 mbar. When calibrating is done in high-altitude
conditions or at low ambient pressure, PO2 indications will be
higher as pro rata.
When calibrating at ambient pressure equal more than 1,000
mbar, PO2 indications will be higher as pro rata.
Take into account this information when planning your dives!
