Notes on Using the Wireless LAN Function of the Equipment
(wireless network models only)
1 Make sure you use this product within the wireless functional range as below:
 Operating frequency: 2.4 - 2.4835 GHz
 Equivalent isotropic radiated power (EIRP): ≤ 100 mW
 Maximum power spectral density: ≤ 10 dBm / MHz (EIRP)
 Carrier frequency tolerance: 20 ppm
 Out-of-band emission power (Outside the 2.4 to 2.4835 GHz frequency band)
≤-80 dBm / Hz (EIRP)
Spurious emission (radiation) power (Outside the range of the corresponding carrier ± 2.5

times the channel bandwidth):
≤-36 dBm / 100 kHz (30 - 1000 MHz)
≤-33 dBm / 100 kHz (2.4 - 2.4835 GHz)
≤-40 dBm / 1 MHz (3.4 - 3.53 GHz)
≤-40 dBm / 1 MHz (5.725 - 5.85 GHz)
≤-30 dBm / 1 MHz (1 - 12.75 GHz for others)
2 Do not, without appropriate permission, attempt to alter the emission frequency or increase the
emission power (including by installing an additional RF power amplifier), or connect any
external antenna or use any unspecified transmitting antenna.
3 This equipment must not cause harmful interference to other radio services. In case such
interference occurred, the equipment must be stopped immediately and cannot be used until
the appropriate measures are taken to eliminate the harmful interference.
4 This micro-power wireless equipment must accept any interference caused by the legal
operation of other radio services or radiated interference received from the industrial, scientific
and medical appliances.
5 Do not use this equipment anywhere near the plane or airport.
