indicators appear below.

1. LCD Display
The dot-matrix LCD display is used to show system status, fault indications, and general in-use
information, as well as being used to configure the menu system items.
2. Back Button
The Back push-button is used to exit the current menu screen, and to traverse back through the
menus, ultimately to the stand-by screen.
Pressing the dedicated push-button once will exit the current menu level. When you have finished
editing the menu options, you should use the dedicated push-button to exit the menu system
completely. You need to press the button a suitable number of times to get back to the stand-by
screen (the one with the Ross Video logo, one press
back from the top level menu). This will save
any changes that you have made to the non-volatile memory.
Pressing the Back button while pressing the Rotary/Push Control knob at the same time will
lock the front panel controls. Pressing both again will unlock the front panel controls.
3. Rotary / Push Control Knob
The Rotary / Push control has two functions:
• the rotary function is used to navigate up or down items in a menu, or to cycle through a
range of values relating to a menu item,
• the push function is used to confirm a menu item selection for editing, to exit menu item
editing, or take you “forward” to the next menu item.
Selecting or editing menu items requires you to turn the Rotary Control in order to select or
change the highlighted menu item / setting, then to press the Rotary Control to select or confirm
that menu item / setting. Pressing the Rotary Control will select the highlighted menu item for
editing, exit menu item editing, or take you to the next menu level. Note that there may be more
menu lines available than can be displayed on the LCD screen; be sure to scroll down (or up) to
find the required entry.
For some menu items, there may be many values to scroll though. In order to assist in quickly
accessing the required value(s), software monitoring the signals from the rotary control applies a
ballistic response to modify the rate at which the menu values change:
• If the rotations/second occur at a reasonably constant rate, the speed at which menu
values change will increase exponentially.
• If the rotations/second decreases, the ballistic response also decreases.
• If the rotations/second stops for more than 1 second, then the ballistic response resets to
normal action.
• Switching the rotation direction will preserve the modified rate, assuming that the
direction change occurred with minimal delay.
