Confidential document and information
The primary PTT is protected by extrusions to avoid inadvertent activation, as well as
allowing localization of the button when operating in low visibility.
The volume control and power ON/OFF buttons are located on the side of the unit.
There is also an AIS button for activating sending of position reports compatible with the AIS
system. Activation of position reports will send AIS-SART formatted messages. The AIS
compatible functionality can also be activated remotely from the PNG Control Panel.
On the front, there are two buttons for selecting the active configuration when in intercom
mode, or the active channel when in direct mode. There are also two buttons for menu
navigation (MENU and OK). These four buttons (MENU, OK, configuration up and
configuration down) are used to implement a four-way menu navigation.
The MP50 implements vocal audio feedback on some of the user operations. The vocal
feedback helps with the navigation and alerts the operator of unintended operation of buttons
and functions.
The display can show two letters at a time, and implements scrolling of text to display longer
strings. Most menu entries are therefore presented with a two-letter acronym, before the full
menu name is scrolled.
