[TenTec] Haunted Omni V keypad beep without pressing any buttons

[n2ouv at optonline.net]

Hello all,

Just wondering if anyone has ever had a problem with an Omni V where if the rig is sitting idle in receive mode you every once in while hear the beep as if you pressed a key on the keypad. 

Nothing changes or happens as if you did press a key it just beeps. Really spooky thing.

Just recently got the rig and have been putting it through its paces and noticed this issue. 
It is stock and I do have the V.9 chip but havent installed it yet.

Any ideas or suggestioins?

TIA
