Installation Setup and Test
6.1 Initial Power On
The TY96 will display a splash screen when the radio is first switched on. The splash screen shows the
software versions currently loaded and what model of radio is connected.
6.2 Configuration Items
There are a small number of installation parameters that can be adjusted. Those that are expected to be
operated in flight are accessed by pressing and holding the MON button for approximately 2 seconds.
Those that are infrequently accessed only appear when a second step is accomplished by pressing and
holding the MEM button for 2 seconds after the settings screen is displayed.
The individual setup items are selected using the large tuning knob, and adjusted using the small tuning
knob. Pressing MON again will exit from the setup mode.
The base set of parameters are:
•
Intercom Volume

Intercom Squelch

6.2.1
Intercom Volume
This setting controls the volume of the built-in intercom.
6.2.2
Intercom Squelch
The intercom includes a voice activated squelch control, to limit the background noise heard over the
intercom. Increasing the squelch level requires a louder microphone input to turn on the intercom. If
you set the intercom squelch to minimum (turning the knob anti clockwise), then you can speak quietly
or at greater distance from the mic. If you have trouble with audible background noise opening the
squelch when you’re not speaking, you can increase the squelch to make the radio to ignore
background noise.
6.2.3
Music Volume
This setting controls the volume of the stereo music input. The listening level is controlled by this
setting, and also by the volume controls on the music source. Set the music volume so that a
reasonable level is achieved with the source set to a typical playback setting.
