Changing Options During a Call
Image
The Image function allows you to:
• Change the screen size.
• Set high or low resolution.
• Change the relationship between frames per second and the image resolution.
To change the screen options:
1.
Press the image button.
A transparent TV icon is displayed and remains on until switched to another
mode.
2.
Use The Control keys to make changes:
Change the screen size on your LCD.
You may want to change image size, for
example, when an external video source does
not fit on the screen.
Use the / buttons.
Change the resolution of SENT video.
You may need to drop to low resolution during
a call if you run out of bandwidth (and the
speech becomes distorted). Or during a
videoconference, low resolution may be
required by the MCU.
Change to high resolution using the Up arrow
key, or select low resolution using the Down
arrow key.
The words “Low Resolution” or “High
Resolution” are displayed on screen.
Use the Arrow keys.
Motion versus resolution
Choose a value from 1 to 9 to set your
preference for motion versus detail in the
video image. Setting the value to 1 maximizes
detail, while setting it to 9 maximizes motion.
The default setting is 5.
Use the Number keys.
