SAFETY INFORMATION FOR IBM-3920
Your cordless telephone contains a low power transmitter. When the Push-to Talk (PTT)
button is pushed it sends out radio frequency (RF) signals. This device is authorized to
operate at a duty factor not to exceed 50%. In August 1996, the Federal
Communications Commission (FCC) adopted RF exposure guidelines with safety levels
for hand-held wireless devices.
CAUTION:
To maintain compliance with the FCC' s RF exposure guidelines, hold
the transmitter and antenna at least 0.5 inches (1.25 centimeters) from your face with
the antenna pointed up and away from the face. If you wear the handset on your body
while using the headset accessory, use only the manufacturers supplied belt clip for this
product and ensure that the antenna is at least 1 inches (2.5 centimeters) from your
body when transmitting.
Use only the supplied antenna. Unauthorized antennas, modifications, or attachments
could damage the transmitter and may violate FCC regulations.
