To perform the test, select Receive DSC and press OK. Following this, the DSC frequency will
appear in the display. Press OK again and activate the transmitter to send a DSC call.
The received MMSI number, DSC data and the measured frequency and power values will be
stored in the test box memory and at the same time appear in the LCD display, line by line.
You may toggle between the lines using ↑ and ↓ to view all the results.

If you only want to check DSC data and frequency (no power measurement), connect the
telescopic VHF antenna to RF IN and use this setup:
If there are DSC transmissions from more than one radio in the area – for instance in ports with
many ships – the test box will receive data from the radio first detected.
To make sure that the test box will be receiving data from one particular radio, use the test
mode "Receive DSC sele" below.
Receive DSC sele
In the Receive DSC sele mode, the test box will receive data from the radio having its MMSI
number currently registered in the test box. So, please check and change number, if required,
using the Edit ship's MMSI menu on page 12.
Use the same setup as above.
