CVC-152 Notes
1. The FREQUENCY SELECTOR knobs tune the radio transceiver directly. The display shows the
frequencies to which the radio transceiver is actually tuned. In addition to the CVC-152, the Chelton
Series III transceivers may also be tuned by an ARINC 429 digital bus. In addition to the CVC-152, the
Chelton FliteLine transceivers may be tuned by either ARINC 429 digital bus or Controller Area Network
(CAN) Bus.

2. Display intensity and panel lighting are controlled by external dimmer controls.
3. Pressing and holding the FREQUENCY TRANSFER button for at least 7 seconds before releasing it
sets the COM active frequency to 121.50 MHz and puts the unit into the active tuning mode. This is true
even if segments of the display are faulty or a lighting failure occurs. From this known reference point,
any other frequency may be set by counting detents of the FREQUENCY SELECTOR knobs as they
are rotated. Each clockwise detent of the outer knob is one Megahertz difference. Each clockwise
detent of the inner knob is 25kHz or 8.33 kHz difference.

4. The FREQUENCY SELECTOR knobs rotate continuously through all detents without end stops. After
rotating the outer knob clockwise to the highest number, the next detent will be the lowest number (118

MHz).
5. Pressing and holding the left pushbutton (PWR) for more than 1 second will trigger the system to
shutdown. A warning screen will display a countdown. Releasing the PWR button before the count has
expired will return the unit to the display screen active prior to initiating the shutdown.
expired will return the unit to the display screen active prior to initiating the shutdown.
Should the system become unresponsive, a hardware failsafe shutdown can be initiated. Under this
circumstance, press and hold the PWR button for 12-15 seconds. There is no indication other than
actual system shutdown and an audible click.

6. The system that is in the off condition may be turned on by simply pressing the PWR button
momentarily.
7. Systems configured for ARINC 410 (2x5) Digital Interface will only support fixed channel operation.
There is no TX indicator on a system configured for ARINC 410 interface.
