Frequently-Asked Questions
Solutions
In the HS-2850, each input source must be
associated with only one button. If you
associate one source
one button, you will then see corrupted
images in small windows of the HS-
2850 Multiview display. To avoid this
please make sure your XPT setting is
configured to the one input to one button
configuration.
After the TIMER button is enabled on the
selected PGM channel, the countdown
timer will start on the PGM display as soon
as the user switches to the selected PGM
channel.
In this case, the Video XPT feature might
have been activated and if Audio is set to
FIX, the Audio XPT must also be enabled to
avoid out-of-sync audio and video.
Check the audio input as this could be due
an absence of the audio input.
This can occur as a result of frame rate
change (for example 1080i50  1080i59).
To correct this issue, please factory reset
your machine.
Please press the Enter key on the MENU
area of the keyboard. After that, the OSD
menu will show on the screen. Please

to high brightness/4 equals to high
brightness. For details, please refer to Keys
Brightness in the chapter 2.2.7 OSD MENU
Options.
