Pressing this key switches the message screen between the first receiver screen
page and the second receiver screen page.
For example, if the current screen is currently showing the first receiver page (i.e.
518 kHz NAVTEX message display), a first keypress changes the display to show
the second receiver page ( i.e. 490 kHz/4209.5 kHz message display). A second press
changes it back to the first receiver page. See paragraph 3.5 for more details.

Pressing this key silences
the audible alarm. The

).
Holding down the key accelerates the scrolling.

When a menu is currently being displayed, pressing this key selects (highlights)
vertically listed options upward. Press

Left Key

When a NAVTEX message is currently being displayed, a single press of this key
scrolls the message text by one message forward chronologically, displaying a
newer message. Holding down the key accelerates the scroll.
When the newest message (e.g.
200 / 200
) is currently shown, a further keypress
returns you to the oldest message (e.g.
1 / 200
).
・
When a currently displayed menu has horizontally listed options, pressing this
key selects (i.e. highlights) those options in a leftward direction. Be sure to press
after highlighting the desired option.
