Zoom feature not working on DVR D6216

[butt01 0]

Hi,

 

I have set up a DVR and two small cameras. The DVR is a D6216 and the problem I have is that The Zoom +/- feature doses not work. I have tried it both from the remotre and the menu on the DVR itself.

 

Does anyone have any ideas as to why the zoom feature does not work.

 

Thanks
