Want to control 3 additional radio functios from a remote location?

Here's how:

On the front board, locate the three solder pads labeled OPF0, OPF1, & OPF2. They are located near the corner. Applying a ground to these pads will activate whatever function that you programmed into OPF0, OPF1, &OPF2 in the menu "Key and Display Assign".



Remotely turn on/off scan

Remotly return the radio to its home channel.
