Cannot Send Data to Radio
Last Updated: 02/17/2015
If you are able to get data from the radio but you get an error message when trying to send data to it, contact technical support at 800-921-4834 or direct at 303-586-6510 between 8 AM - 5 PM Mountain Time, Monday through Friday, or email us at

Have the following information ready:

- Is your radio an IC-746 or an IC-746 PRO?

- You will find a date printed on the front of the installation CD. What is that date?

- Please be ready to provide proof of purchase. If you purchased the software directly from us, we will have that information for you, but otherwise we will need to see an email order confirmation or a scan of your invoice.
