Important Safety Information
Loud sound hazard:
• Do not operate with the loudspeaker less than 30 cm (12")
from your ear.
• Do not use with the headset at high sound levels for
extended periods.
Failure to observe these precautions may result in injury.
Electric shock hazard:
• Do not attempt to repair this unit. It contains no user-
serviceable parts.
• Use only with accessories and replacement parts recom-
mended by Greenlee.
• Do not expose the unit to extreme temperatures or high
humidity. Refer to “Specifications.”
• Beware ringing voltage that may be present on telecom-
munication circuits.
• Do not use anti-static surface treatments, e.g., cleaners or
polishes; these can leave the surface slightly conductive,
which may pose a safety risk allowing higher voltages
accidentally encountered to track over the surface to your
hand.
Failure to observe these precautions may result in injury and
can damage the instrument.
