Accept only own call sign: if this entry is active then only one D-Star transceiver
with the same call sign as the DV4mini call sign can operate via the hotspot. All
others are locked out. This is a requirement in some countries regulations.
Language: English or German. This setting changes the language of the user
interface and also the language of the announcements.
Bootloader/Firmware update:
In order to update the frmware a boot loader is installed in the DV4mini. This is
how you create a frmware update:
First you save the new frmware fle on your computer. Normally you will fnd it at
www.ham-dmr.de/dv4m
Then you click on the screen Expert mode on Start-Bootloader .
This makes the LEDs on the stick blink in color and then the red one will stay on.
To the question whether you want to make an update you answer YES. Now the
program terminates.
You restart the program and click on Flash Firmware.
This opens a fle selection window and you navigate to the location of the new
frmware fle. After selecting it the frmware will be updated. Now end the program
and restart it again. It may take a little while until the stick is found again. Be
patient.
