| * Check the instrument alignment. Is flux getting through to the detector? How long has it been since the last NIRO camera alignment? Classic and CLIMB programs can run for about an hour before the light will drift from the central pixel. Use the Classic or CLIMB gui to view the light on the pixels by clicking the PICTURE tab and then the PIXEL AREA button. Turn the camera off with the STOP button. Is the right dither power turned on? CLIMB 1 and Classic use different dithers. If Classic or CLIMB fringes are found in a scan, but not when in recording mode, the dither powers are likely not on. Are the camera settings correct for the seeing conditions and flux levels? | * Check the instrument alignment. Is flux getting through to the detector?

| You may have to reinitialize the scope on a bright star. If the powers were turned off quickly when the problem was noticed, the position of the scope should be retained and slewing to a bright star will get it in the finder.

| + | Be aware that when restarting a dome server, the telescopes position may not be retained and the dome gui may display Az: 0.0. El: 0.0. The gui will scroll messages that say Az: 0.0. El: 0.0 with an error in scope position. If the scope is known to be at STOW position, you can manually enter the scope' | ||

| + | Also be aware that the gains do not always return to the normal values of Slew 4-7 and Tracking 7-10 when a dome server has crashed and is restarted. They may come up as Gain 22 for all axes and modes and they will need to be turned down or the scopes will oscillate badly. | ||
