SET-UP AND OPERATION
After a 15 second warm-up period, the light output will stabilize at its
normal intensity. The fiber optic bundle must be plugged in to stabilize
light output.
CAUTION: Verify that the supply voltage matches the voltage
range indicated on the rear of the Welch Allyn Light Source.
To prevent temporary blinding, turn power on only after the
fiber optic bundle is plugged in and the intensity control knob
is set to the minimum position.
The fiber optic bundle port is hot when fiber optic bundle
is removed.
1. Plug the Welch Allyn Light Source into a hospital-grade receptacle.
2. Turn the light-intensity control knob to its minimum position. Plug the fiber
optic bundle into the illuminator port and connect the opposite end to the
instrument.
3. Turn the power switch to the on position. The lamp will take 15 seconds
to complete its warm-up cycle.
4. Set light intensity to desired level.
5. Turn unit off when not in use.
NOTE: Do not restart lamp immediately after turning off. The lamp
may fail to start. If this occurs, turn the power switch off and wait
15 seconds before restarting the Welch Allyn Light Source.
