RF SAFETY INFORMATION
The USB modem has an internal antenna. For optimum
performance with minimum power consumption do not
shield the device or cover with any object. Covering the
antenna affects signal quality and may cause the modem
to operate at a higher power level than needed.
RADIO FREQUENCY ENERGY
The USB modem is a low-power radio transmitter and
receiver. When switched on it intermittently transmits
radio frequency (RF) energy (radio waves). The transmit
power level is optimized for best performance and
automatically reduces when there is good quality
reception. Maximum power is only used at the edge of
network coverage so under most circumstances the power
output is very low. Under poor network conditions the
modem transmits at a higher power level and may get hot.
