TROUBLESHOOTING
No Picture-in-Picture Option Appears on Main Menu
If no PIP menu is available from the Main Menu (where PIP is installed), the PIP has not
been detected by the controller. Recycle power to the unit by disconnecting power and
then reconnecting power. If no PIP is detected again when the Main Menu is powered up
again, call Z Microsystems’ Customer Support Department for assistance.
No Picture-in-Picture Display Image
There are a few scenarios which may cause the image on the optional PIP to be black. To
eliminate these concerns, follow the instructions below in the order they are presented:
1. Ensure the PIP is viewing something with contrast and shape and can be
easily detected under normal viewing conditions.
2. If the PIP is viewing something with these qualities, and should be easily
detected, the values associated with Contrast and Color Balance may re-
quire adjustment. To ensure the Contrast and Color Balance values are not
the cause of the black screen, set the values to the factory default settings.
3. In some Command Console confi gurations, there are two inputs for the
RGB channel and one input for the Video channel. Ensure the correct
channel is chosen for the desired PIP.
4. If the black screen is for the RGB PIP, perform an Auto Adjust in the PIP
submenu.
5. If no PIP image appears, call Z Microsystems’ Customer Support Depart-
ment for assistance.
