10.6.2.3 VHF Link: Silent mode
The silent mode is a special mode for travelling in areas where the transmission of own position impose risk to the
user. When active, no signals are sent from the Transponder unit, but the user is still able to receive information
from other vessels.
If the
Silent Mode is active for more than 15 minutes, the event is logged in the History Log.
The Silent Mode disables the AIS Transmitter functionality and will make the
Vessel invisible on the AIS system and impose a risk to other and own vessels.
10.6.2.4 VHF Link: Display devices in TEST mode
When AIS-SART was introduced as alternative to traditional Radar SART in 2011, it was obvious that testing such
equipment could lead to much “noise” on nearby ships AIS Transponders and ECS/ECDIS as this AIS-SART icon/text
message would pop up on all nearby vessels within VHF range (5-40 nautical miles). Therefore, revisions in the AIS
standards were made so the person who wants to test the AIS on-board the ship, must first activate this menu item
before it will be shown on the vessels AIS and ECS/ECDIS or Chart Plotter.
This options also applies to EPIRB and MOB (Man
Over Board) devices in test mode.

Observe that here are “2 popups” received from 2 different AIS-SARTs and each
“popup” must be acknowledged. Also observe that locating devices are displayed
in top of the list in the background, and with RED color.
