Using The Handles; Cleaning - Welch Allyn GS 777 Directions For Use Manual

Welch Allyn

Using the Handles

Ensure that the transformer is plugged in.
1. Lift the handle from the cradle. The instrument
powers on. Only one instrument can be
powered at a time.
2. Adjust the light output by turning the rheostat
on the handle.
• Turning the rheostat clockwise increases
the light output.
• Turning the rheostat counterclockwise
decreases the light output.
Note: Decreasing the light output to the
minimum level does not power down the
instrument.
3. Follow the directions for use for the instrument
head when examining a patient.
CAUTION: To prevent damage, do not
overstretch the cords on the handles.
CAUTION: To minimize the external housing
temperature of the instrument head, on-time
must not exceed 2 minutes, and off-time
must be a minimum of 10 minutes.
4. Return the handle to the cradle. The 3.5V
instrument powers down.

Cleaning

WARNING: Before you clean the
transformer, unplug it from the wall socket.

CAUTION: Do not use CaviWipes to clean
the blue handle cradles. This cleaning agent
