DANPHONE Futronic MKII User Manual page 33

The test box is very sensitive to receiving signals from emergency beacons. If the display shows
"Please wait", the test box has detected the transmission but is still waiting for the rest to follow.
If nothing happens, it is usually because the signal is too strong. Then, try to move the beacon
further away or replace the 20 dB attenuator by a 40 dB.
1) Select the 406 MHz EPIRB test mode and press OK.
2) Set Number.
As you may wish to test several beacons in a row, each beacon can be given its own individual
set number for recognition. Default number is 1. Press OK to confirm, or press ↑ or ↓ to change
to another number.
3) Press OK and "Detect freq." will appear in the display.
406 MHz beacons are available for transmitting at various frequencies. If the beacon does not
provide any printed information of its frequency, select Detect freq. and the test box will
automatically detect the frequency and set itself for testing here. If the beacon provides
information of its frequency, you are advised to select the frequency manually. Press ↑ in order
to go to 406.025 MHz and further on to 406.028, 406.037 and 406.040 MHz. Press ↓ to go to
121.5 MHz.
4a) In the manual mode, select frequency and press OK. The display will show "Waiting..." for
transmission. Then activate the beacon in its test mode, and the test box will perform a full test,
measuring the frequency and signal strength level during the test transmission and recording
the data strings contained in the transmission.
4b) In the automatic Detect freq. mode, press OK and the test box will show "Detecting..." in the
display. Then activate the beacon and wait for the detected frequency to appear in the display.
Upon this, press OK and re-activate the beacon in order to perform the full test.
"Received OK" in the display confirms successful test.
Test results are automatically stored in the memory and presented on the display where they
can be viewed line by line. Use ↓ and ↑ to toggle between the lines.
In the 121.5 MHz test mode there is a choice between Ord (Ordinary) and Img (Image). First,
select Ord and Frq to measure the frequency. Then select Img and Frq to measure the
frequency again. Same result from both tests proves that the measured frequency is correct and
not just an image frequency.
