WARNING
These radio systems shall be installed by a RF/radio professional familiar with the
applicable rules. Installation of all antennas shall be performed in a manner that will
provide at least the MPE Distance from the direction of maximum radiation, to any user
or member of the public and consistent with the settings in the applicable antenna
installation compliance section below.
FCC antenna compliance
Since professional installation is required, standard RF connectors are used. Adapters or
custom coaxial cables may be required to connect the radio output connector to the
desired antenna.
Any antenna from a reputable manufacturer with desired bandwidth, gain/pattern
coverage, and have an input impedance of approximately 50 ohms can be used.
Exposure Compliance
FCC ID: PEJ-XETA2
It is the responsibility of the licensee or user to guarantee compliance with the
appropriate MPE regulations when operating this device in a way other than described
herein. The installer of this equipment must ensure the antenna is located or oriented
such that it does not emit an RF field in excess guidelines as posted in the 47 CFR
Bulletin 65/47CFR § 1.1310 of the Federal Communications Commission.
The XetaWave XETA2 uses a low power radio frequency transmitter. The concentrated
energy from an antenna may also pose a health hazard in the near field. People should
not be near the antenna when the radio link is operating as general practice and
maintain a safe distance as calculated below.
The following calculations are based off the Maximum Permissible Exposure
requirements as outlined by the FCC.
The MPED (Maximum Permissible Exposure Distance) is calculated based on the limits
for a General Population/Uncontrolled Exposure in the 30 -300 MHz frequency band
using the stated MPE power density limit of 0.2 mW/cm2. The following table provides
safe distance for several power levels and antennas besides the worst case for
convenience.

Specifications
To calculate safe distance:
Equation 2:
Where: MPED is Maximum Permissible Exposure Distance or safe distance.
All quantities are calculated in linear or numeric quantities.
The exposure limit, MPED, and conducted power units must be consistent, mW and cm
for this case.
Duty cycle is set using packet sizes for master and slave. Packet sizes are set in the radio
Network Configuration Menu. At Power up and with no data transmitting, the radios
will transmit or beacon with a duty cycle of 6 to 10% depending upon modulation
setting. The maximum Duty Cycle is 100%.

1.5 Configuration
The following parameters are available for selection by the installer at the end-product
level for all products that incorporate the Xeta2m-T:
- Frequency (Master and Slave)
- Modulation Type
The installer shall set the frequency (or pair of frequencies) according to the
requirements of the user’s license. There are different modulations and bandwidths
available. The available modulations are limited to those listed in paragraph 1.1, and
6
further limited by frequency selection. A modulation shall be selected according to the
bandwidth (channel size and number of channels) that is specified in the user’s license.
Lower speeds have generally better sensitivity and longer range, while higher speeds
offer greater data throughput.
1.6 Password
The installer shall set a password for the end-product to prevent alteration of the radio
parameters by unauthorized parties. The procedure for setting the password is
described in the user manual for the end-product that incorporates the Xeta2m-T.
