DayStar Filters Combo Quark Hydrogen Alpha Eyepiece マニュアル
Yellow, never goes green LED indication:
If after 20 minutes of the same knob position setting the LED has not
turned green, the ambient temperature may be too hot or too cold for the Quark
to regulate the temperature. However, the filter may still be usable while slightly
mistuned and performance may not be affected.
This can also occur if plugged into a computer USB port, which causes
the filter heater to reduce its current draw. Use the supplied power adapter or a
source rated for 1.5 amps, not a data USB port.
Red LED indication:
This usually indicates that the Quark is not receiving enough voltage. If
powered by battery, recharge the battery. Make sure to use the supplied AC/DC
wall adapter, as cell phone chargers and PC USB ports do not have enough
current capability for the Quark.
Red indication can also mean an electrical fault in the Quark electronics.
If power source changes do not resolve the red indication, please return the
Quark to DayStar for inspection and repair.
