The multipoint corrections are protected with switch SW4 (see F IGURE
6-1 ). Turn the switch SW4 to write ENABLE position (ON) to be able
to turn the multipoint corrections on or off.
NOTE Changing the multipoint corrections on or off will automatically
cancel the previous date of calibration of the transmitter (see CALD
