Certications
United States FCC
This equipment has been tested and found to comply with the limits for a Class B digital
devices, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of more of the following
measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Warning: Changes or modications not expressly approved by Monnit could void
the user’s authority to operate the equipment.
RF Exposure
Monnit Wireless Sensors and Ethernet Gateway Contain: FCC ID: ZTL-RFSC1
This device has been designed to operate with an approved antenna listed below, and
having a maximum gain of 5.1 dBi. Antennas not included in this list or having a gain
greater than 5.1 dBi are strictly prohibited for use with this device. The required antenna
impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that
required for successful communication.
Approved Antennas
The following antennas are approved for use with Monnit devices.
• Hyperlink HG905RD-RSP (5.1 dBi Rubber Duck)
• Pulse W1063 (3.0 dBi Rubber Duck)
• ChangHong GSM-09 (2.0 dBi Rubber Duck)
• Specialized Manufacturing MC-ANT-20/4.0C (4” whip)
WARNING: To satisfy FCC RF exposure requirements for mobile
transmitting devices, the antenna used for this transmitter must not be
co-located in conjunction with any other antenna or transmitter.
