Frequency Step Size Changing the frequency step size by
pressing the PUSH/STEP button on one
controller does not affect the other controller.
Brightness The brightness is separately adjusted on
each controller.
Memory The frequencies stored in the memory are
local to each controller. The memory data is
not transferred between controllers, although
a frequency selected from the memory will
appear on the screen on the other controller.
General Low Temperature Operation
The TY91/TY92 is certified to operate correctly down to -20°C, but at
low temperatures the controller display may be impaired. On a cold
day you may need to wait for the cockpit to warm up to ensure normal
operation.

maintenance organisation. Press the flip-flop button to clear the
