6. Installation Setup and Test
6.1 Initial Power On
The TC90 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
 Music Volume
 Music Muting
The items accessed on the second level of menu are:
 Frequency Step Size
 Auxiliary Input Volume
 Auxiliary Input Muting
 Sidetone Volume
 Receiver Squelch Offset
 Microphone gain adjustment
 Display Dim and Brightness settings
 Single PTT configuration
 Audio Test Tones
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.
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.
6.2.4 Music Muting
Turn this feature ON if the music should mute during radio reception. Turning this feature off leaves
the music playing during reception. The music always mutes when the radio is transmitting.
