necessary to adjust the darkest setting of the backlight to best match other equipment and to improve
the cockpit appearance at night.
Note – it is only practical to do this in pitch darkness, since that is the in-flight environment that you
are trying to reproduce. If you are working in a hangar with any other lighting it may be better to leave
the setting in the mid-range.
6.2.13 LCD Brightness Curve
The actual maximum brightness of the LCD cannot be increased with this control. What it controls is
the rate at which the lighting increases in brightness as the ambient light increases. This allows the
brightness to be matched to other avionics displays during light level changes as far as possible.
6.2.14 Single PTT Mode
In the factory standard configuration pressing PTT1 sends only Mic 1 to the transmitter; PTT2 sends
only Mic 2. For a retrofit installation, for example when replacing an SL40 radio, a single PTT is
shared between the two microphones. Enabling Single PTT mode means that whenever PTT1 is
pressed both Mic 1 and Mic 2 audio is sent to the transmitter.
