[CA] [CA11] Axiom Pro - OK Button on Rotary Dial Not Working Properly

[Type1]

In the radar app with the VRM/EBL #1 active in edit mode and the range at say 3/4 or 1.5 miles, we will typically range out to 1.5 or 3 miles to check for traffic every few minutes. We will then range back in and reactivate the VRM/EBL.

The button sequence is:

Press the back button to freeze the VRM/EBL and enable the range out function.
Range out to 1.5 or 3 miles with the rotary knob on the uni-controller.
Range back in to 3/4 or 1.5 miles with the rotary knob.
Move the curser off the vessel with the directional controls on the uni-controller to enable the appropriate popup menu.
Press the OK button on the uni-controller to bring up the menu
Move down to the bottom of the menu to "more options" using the rotary dial or the directional controls (many more button presses).
Press the OK button again to bring up another menu including both VRM/EBL controls.
Move down to highlight the option desired (Adjust EBL/VRM #1) using the rotary knob or the directional controls (more button presses).
Press the OK button to select VRM/EBL #1 in edit mode.

This is the point at which the OK button often does not work on the first try, requiring several pushes or a long pause before it works. Sometimes it will not work at all and we need to back out of the menu system and restart the sequence to reactivate the VRM/EBL.

We normally have all three MFD in operation. The two 12" displays are at the forward nav station, one on chart and the other on radar. The 9" display is at the aft coxswain's station. We operate in dual range mode with the aft screen in split screen chart/radar mode. Range in/out operations can occur simultaneously on forward and aft displays.

Hopefully this will help to troubleshoot the issue.

Thanks!
