Important
Preventing malfunction
• Never place the equipment in close proximity of electric motors,
welding equipment or other devices generating strong (electro)
magnetic fields. Exposure to strong (electro) magnetic fields
may cause malfunction and corrupt the communication.
• Moving the equipment rapidly between warm and cold
temperatures may cause condensation (water droplets) to form
on its internal and external surfaces. Water droplets may cause
malfunction of the equipment and corrupt or end
communication or damage the equipment. When condensation
is noticed, stop using the equipment. Switch off the phone,
remove the battery and unplug the mains adapter from the
power outlet. Wait until the moisture evaporates from the
equipment before putting it in operation again.
• Avoid accidental drop of the phone. Use the clip, security clip or
carrying case specified for carrying purposes of the phone.
• Avoid the phone being squeezed between furniture and your
body when carrying the phone in your pocket or attached to
clothing.
Exposure to Radio Frequency Signals (SA)
A cordless telephone is a radio transmitter and receiver. It is
designed and manufactured not to exceed the emission limit for
exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the US government and Canada.
These limits are part of comprehensive guidelines and established
permitted levels of RF energy for the general population. These
guidelines are based on the safety standards previously set by both
US and international standard bodies. These standards include a
substantial safety margin designed to assure the safety of all
persons, regardless of age and health.
The exposure standards for cordless telephones employs a unit of
measure known as the Specific Absorption Rate, or SAR. The SAR
limit set by the FCC and Canada is 1.6W/kg averaged over one
gram of tissue.
Tests for SAR are conducted using standard operating positions
specified by the FCC with the phone transmitting at its highest
certified power level in all tested frequency bands.
