PROBLEM	SOLUTION
No Video.	•	Make sure the BasicDome is properly powered.
	•	Ensure all cables are connected properly.
No Control of Camera.	•	Make sure the address is set properly.
	•	Make sure the biphase or RS-232 is connected.
	•	Make sure other cameras can be controlled; if not, check
		the control system.
Camera moves when moving other cameras.	•	Make sure the address is set properly. If the FastAddress is
		not set, the camera will respond to commands for any
		address.
Picture Dark.	•	Make sure the Gain Control is on (ON-43-ENTER).
	•	Make sure the Iris level has not been changed; if so, adjust
		using IRIS control on the keyboard, to permanently adjust,
		use ON-11-ENTER.
Cannot access user settings.	•	Unlock commands (OFF-90-ENTER).
	NOTE: Commands will automatically lock 30 minutes after being
		unlocked.
Colors are not correct.	1.	Try resetting factory defaults (ON-40-ENTER).
	2.	Position the camera so the entire view is white (piece of
		paper or white wall).
	3.	Turn on White Balance (OFF-30-ENTER). Move the joystick
		until one shot is selected. Wait 2 seconds. Press IRIS to
		return.
	4.	If this does not work, restore factory defaults
		(SET-899-ENTER). Note that this will erase all presets and
		settings.
	5.	Once you have restored the proper settings, it is
		recommended to store those settings in Preset #1
		(SET-1-ENTER) so they are recalled each time the Preset
		is called.
Periodic loss of control.	•	Verify that a 110 ohm resistor is across the +/- biphase
		code terminals at the last dome being controlled.
Background is too bright to see subject.	•	Turn on Backlight Compensation (ON-20-ENTER).
	NOTE: Backlight Conpensation will turn off with any camera
		movement.
Picture is rolling, noisy, or distorted.	•	Electronic AC power line noise may distort the picture and
		cause loss of Sync. If the picture is distorted, try switching
		to Internal Crystal (OFF-42-ENTER). If this corrects the
		picture problems, there may be excessive line noise on the
		power supply.
