Common Questions and Issues
I am receiving a "Nothing Enabled Error" after programming my radio
If you imported info into ARC500 and/or uploaded programming to your scanner and you receive the message "Nothing Enabled" on your radio, you need to assign the frequencies or talkgroups to a "scanlist". This can be done easily in the software by going to the scanlist column next to the alpha tag column, in either Coventional or Talkgroup under Scannable Objects, and typing in the scanlist number. When each frequency and/or talkgroup has been assigned a scanlist you can then proceed with uploading the information to the scanner.
No data is transferred to my scanner.
First make sure you plugged the USB cable in the PC/IF jack and not the headphone jack. Also verify that the led's on the USB cable are flashing during the data transfer.
If they are not flashing you selected the incorrect usb/com port and/or the driver is not installed correctly. Re-install the USB driver. Also try a different USB port.
I am receiving a "Init not ok. Can't read user data" message when trying to import data from the database
This message usually indicates that a firewall is blocking the software to access the internet. Add the ARC software to the safelist of your firewall software.
You may also see this message on satellite internet connections due to the latency on those networks. The webimport may not work on satellite internet, use dialup or cable/DSL instead. 'Hughesnet' users must disable the Turbopage option.
I lost my software registration.
