D NEXT and PREV Function Keys -- NEXT and PREV function keys move to adjacent pages where more than one page of the same title is used D RADIO Function Key -- The RADIO function key activates the radio tuning function and displays the RADIO 1/2 page, D Tuning Knob -- The tuning knob is used to dial in frequencies or other numeric values.
OPERATING MANUAL 2. Page Organization The radio tuning function is accessed via the RADIO function key on the MCDU, which displays the RADIO 1/2 page. All other pages are accessed from RADIO 1/2 using the line select keys or the NEXT and PREV function keys, shown in Figure 32.
OPERATING MANUAL 3. MCDU Tuning Description All of the pages that correspond to a particular radio type (e.g., VHF communications or ADF) are arranged as shown in Figures 33, 34, and 35, and typically consist of a details page along with two memory pages. The details pages allow the specific features of each radio to be configured and provide access to the memory pages associated with each radio type. Figure 34 shows the pages associated with the VHF communications radios.
OPERATING MANUAL Figure 34 shows the pages associated with the VHF navigation radios.
OPERATING MANUAL Figure 36 shows the arrangement of pages associated with the high--frequency (HF) communications radios.
OPERATING MANUAL Figure 37 shows the page associated with the automatic direction finder (ADF).
OPERATING MANUAL Figure 38 shows the pages associated with the Microwave Landing System (MLS) receiver. Figure 38 The RADIO MENU is used for manually tuning the radios. Pushing the RADIO key on the MCDU displays the RADIO MENU page 1/2.
OPERATING MANUAL 2B-- 09-- 20: BASIC OPERATION In keeping with the titling and numbering conventions used by MCDU functions, each MCDU page is arranged with a centered title at the top and a page number in the upper--right corner. Page numbers are formatted as the current page number (among those with the same page title), a slash ”/”, and the number of pages with the same title.
OPERATING MANUAL Pushing the NEXT or PREV key when this page is displayed displays the RADIO MENU page 2/2, shown in Figure 40. Figure 40 When the scratchpad is empty, pushing a line select key either moves the format cursor to the adjacent field, or performs the function indicated by the icon that appears near the key. The icons and their functions are described below. ”Swap” frequencies. This symbol indicates that exchanges between the active and preset frequencies for the associated radio can be made.
OPERATING MANUAL Exclusive selection. This icon is displayed next to a list of mutually exclusive options. Each time the adjacent LSK is pushed, the next options become selected, wrapping around to the first when the last option is reached. The selected value is displayed in the active color (green in this document) and large font, while the other selection are displayed as smaller, white characters. Immediate function.
OPERATING MANUAL If LSK 2R, the second on the right hand side, shown in Figure 41, is pushed, the format cursor and tuning curl move from the 2L field (COM1) to field 2R (COM2). Likewise, pushing LSK 3L moves the format cursor to the active frequency field for VHF NAV 1 radio. Once positioned on a field, turning the tuning knob changes the highlighted frequency.
OPERATING MANUAL When one or more characters are present in the scratchpad, the icons adjacent to fields that accept text entries are removed to indicate that pushing those LSKs enters the scratchpad data into the field, as shown in Figure 42. Entering the contents of the scratchpad into a field, or manually clearing the scratchpad, restores the icons and the normal functions of the line select keys. Scratchpad entries can be made into any editable field at any time.

Displays the COM MEMORY 1/2 page. This section is the COM memory display. This is the default field for the format cursor when the COM 1 or COM 2 pages are displayed. This section can be used in a fashion similar to the RMU’s memory tune feature.
OPERATING MANUAL 2B-- 09-- 40: TCAS/XPDR 1/1 The TCAS/XPDR 1/1 detail page, described below, accesses the controls and data specific to the transponder and TCAS systems, including transponder code, source selections, and operating mode. It also displays the pressure altitude being transmitted and the flight ID. The format cursor defaults to the transponder code preset (4L), which defaults to 1200 (VFR).
OPERATING MANUAL This LSK selects absolute or relative altitude display for TCAS targets. The selected altitude is displayed in green. This section displays the Active TCAS/transponder mode. TA/RA is the typical setting, while the TA ONLY setting inhibits resolution advisories and the STBY places the TCAS system in the standby mode.. These LSKs select the altitude range for TCAS target display. AUTO includes the typical TCAS detection range, while ABOVE and BELOW extend the range in the selected direction.
OPERATING MANUAL 2B-- 09-- 50: HF COM 1/1 The HF communications detail page, described below, is used to control HF tuning (manually and from memory), HF tuning mode selection, transmit power selection, squelch, and to select the operating mode. The tuning functions work just like the VHF COM selections, but each of the tuning modes that HF radios provide: simplex, split (duplex), emergency, and ITU (channel numbers) is also selectable on this page.
OPERATING MANUAL This section displays and controls the HF memory display. This is the default field for the format cursor when the HF 1 or HF 2 pages are displayed. Turning the tuning knob while field 3L is selected cycles through the frequencies stored in memory, by location. This section displays and controls HF COM preset frequency (when in simplex, emergency, or ITU tuning modes) or HF COM receive frequency (when in split tuning mode). The preset feature is not available when in split mode.
OPERATING MANUAL 1. HF MEMORY 1/2 The HF MEMORY 1/2 and 2/2 pages, described below (HF MEMORY 1/2 only), work like the VHF COM and VHF NAV memory pages, but have a slightly different appearance due to the need to support two line frequency displays (for split mode tuning). As a result, space limitations do not allow assigning labels to HF memory locations.
OPERATING MANUAL These areas display and control stored HF COM memories 1--3 (7--9 on HF MEMORY 2/2). When a memory field contains a split frequency pair, the first push of the associated line select key moves the format cursor to the first frequency, the second push moves it to the second frequency field 3L as shown. This LSK displays and controls the Active HF COM frequency on the selected radio (the field title reflects which radio was selected).
OPERATING MANUAL 2B-- 09-- 60: ADF 1 PAGE The ADF page, described below, displays the active, preset, and selected memory frequencies for the automatic direction finders, along with controls for the active mode (antenna or ADF) and the BFO setting (ON or OFF). It is also used to the ADF memory pages.
OPERATING MANUAL This section displays the ADF preset frequency. This section displays and controls the Active ADF frequency on the selected radio (the page title reflects which ADF was selected). Pushing LSK 1L exchanges the active and preset frequencies (when the format cursor is on field 2L) or copies a frequency stored in memory (when the format cursor is on field 3L) for the selected ADF radio. A scratchpad entry into the field replaces the preset frequency with the previous active frequency.
