GENERAL INFORMATION
This pilot’s guide contains information about and instructions for operating the KTR 909/909A UHF Comm Transceiver with the KFS 599A UHF Comm Control Head. The KTR 909 must be installed and operated with a KFS 599A UHF Comm Control Head. The KTR 909A can be operated with either a KFS 599A UHF Comm Control Head or a Radio Management System (RMS) using the ARINC 429 interface. This pilot’s guide only covers operation using the KFS 599A UHF Comm Control Head. Refer to the RMS operating procedures on using the KTR 909A in an RMS installation.

On units without volume control, the audio level is controlled by the aircraft audio/radio control system.
Channel Select Button
The Channel Select button switches the unit between the manual and preset frequency selection modes and also enables the programming
mode. Manual frequency selection (when top display line is blank) |
CHAN |

allows direct tuning of the frequency. Preset frequency selection (Channel number displayed in the top line) allows radio tuning using one of the twenty preset channels or the guard frequency. Pressing and holding the CHAN button for more than three seconds activates the Program Mode.
Frequency/Channel Select Knob
• Manual Frequency Mode — Outer knob tunes the trans- |
|

|
the main and guard frequencies. Both the GD and the MN annunciators illuminate during scan. When a signal is detected, the receiver stops on the active frequency and illuminates the active frequency annunciator. Scanning will resume when the receiver becomes inactive. The ADF mode activates an independent ADF receiver.
