30 • Functional Check Procedures SRG-4500 User Guide (v7.0)
6. Much of the functional check can be carried out immediately. However, some calibration settings are only
guaranteed once functional temperature has stabilized (which should occur after 20 minutes). It is good
practice to soak the instrument before proceeding.
7. 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 either 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 or video outputs;
be sure to scroll down (or up) to find the required entry.
8. Pressing the blue push-button once will exit the current menu level or item.
• When you have finished editing the menu options, you should use the blue 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). This will save any changes that you have made to the non-volatile memory.
9. If preferred, user settings can be adjusted using DashBoard.
Initial Configuration
The SRG-4500 should arrive configured to a “factory default” condition, i.e. all video outputs will have a pattern
selected that is relevant to the format of the output, all of the audio channels will be configured for “1kHz Tone and
Silence”, etc.
Additionally, any pre-ordered options (i.e. GPS or NTP) will have been enabled. This can be confirmed by viewing
the Option Enable page in the menu; enabled options will have valid Option Keys entered for them.
The following procedures will systematically progress through all of the outputs available from the SRG-4500. The
range of menu entries available for each procedure may relate to whether associated options have been enabled.
In all but the first of the procedures that follow, some intermediate instructions relating to cursor movements and
control button presses may have been omitted for clarity.
Also, menu screens almost always contain more lines then can be displayed on the LCD or the OSD - be sure to
scroll up/down to find the menu entry you require.
