Keypad Primary and Secondary functions
Most of the 1090’s keys are dual function. Their primary function is shown in blue on the
lower half while the secondary function is shown in red, on the upper half. To access the
secondary functions press the ‘SHIFT’ key before the required secondary function key. The
display indicates when the ‘SHIFT’ key has been pressed by showing an ‘S’ on the right
hand side. This mode is always cancelled after the secondary function is selected, or the
‘CLEAR’ is pressed.
