VHF COMMUNICATION (Cont)
DISPLAY CONTROL PANEL COM RADIO OPERATION (Cont)
When the FREQ SEL setting is changed to 8.33, the recall COM radio frequency display resolution on the MFDs is three
decimal places for that radio. If the prior recall frequency had two decimal places, the MFD adds the appropriate 0 or 5 to
the frequency value. When the FREQ SEL setting is changed to 25, the recall COM radio frequency display resolution on
the MFDs is 2 decimal places for that radio. If the prior recall frequency had an 8.ss kHz frequency, the MFD changes the
frequency to the next lower valid 25 kHz frequency value. If the prior recall frequency was a 2 digit 25 kHz frequency, the
third decimal digit is removed.
CONTROL DISPLAY UNIT (CDU)
The control display unit (CDU) is also capable of tuning the communication radios, ADF receivers, and ATC transponders.
CDU COM RADIO TUNING
The CDU provides tuning control of both the on-side and cross-side radios. Data entry to the CDU is made through the
scratch pad and the line select keys. Information is entered on the scratchpad, then transferred to the appropriate location
with the adjacent line select key. Messages show if the information entered is not appropriate for the data field. Access to
CDU tuning is accomplished through the TUNE page.
To tune the radio using the CDU execute the following steps:
1. Push the TUN key on the CDU to show the TUNE page.
2. To tune a radio directly, do one of the following steps:
- Enter the frequency into the scratch pad, then push the line select key for the appropriate radio.
- Enter a preset channel number (1 through 20) into the scratch pad, then push the line select key for the appro-
priate radio.
- NAV radios only: Enter the three-letter identifier for the NAVAID, then push the line select key for the appro-
priate radio (NAV 1 or NAV 2).
3. To show the submenu for a particular radio (to set presets, select modes, etc.), push the line select key for the radio
when the scratch pad is empty.
4. To return to the TUNE page from a CONTROL submenu, push the line select key for the radio or push the TUN
key.
