User's Manual

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 surge impedance of approximately 50 ohms can be used.

Maximum antenna gain is 11 dBi in both the 757-758MHz and 787-788 MHz bands.

However, for 11 dBi antenna gain, maximum output power must be reduced at the

radio output or cable with loss of at least 5dB must be employed. It is recommended to

use a low gain antenna, with max gain of 6dBi in the 787-788 MHz bands.

Exposure Compliance

FCC ID: PEJ-9382009

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, or the Council

of European Union as appropriate.

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 300-1500 MHz frequency band

using the stated MPE power density limit of F/1500 mW/cm

for General Population

/Uncontrolled environment.
