pMDDL2450 Regulatory Requirements

 - PLEASE READ THIS SECTION 

CAREFULLY 

 

 WARNING

:   

To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 27 cm or more should be maintained 
between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is 
not recommended.  The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter. 

 

 

 WARNING

:   

Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept 
any interference received including interference that may cause undesired operation. 

 

 WARNING

:   

Changes or modifications not expressly approved by Microhard Systems Inc. could void the user’s authority to operate the equipment. 
This device has been tested with UFL to Reverse Polarity SMA connectors with the antennas listed in Appendix A When integrated in 
OEM products, fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not 
listed in the tables must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). 

 

 WARNING

MAXIMUM EIRP 
FCC Regulations allow up to 36 dBm equivalent isotropically radiated power (EIRP).  Therefore, the sum of the transmitted power 
(in dBm), the cabling loss and the antenna gain cannot exceed 36 dBm.   

 

 WARNING

EQUIPMENT LABELING 
The FCC and IC numbers depend on the model of the radio module. Do NOT use the Marketing Name of the product but the Model 
to distinguish the Certifications Numbers.  This device has been modularly approved.  The manufacturer, product name, and FCC 
and Industry Canada identifiers of this product must appear on the outside label of the end-user equipment. 

 

 WARNING

:   

This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions: 
(1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause 
undesired operation of the device. 

 

SAMPLE LABEL REQUIREMENT for Model: pMDDL2450: 

 

 
 

 
 
 
 
 
 
 

 

 

 

Contains:    

FCC ID: NS918PMDDL2450   IC : 3143A-18PMDDL2450 

This device complies with Part 15 of the FCC Rules.  Operation is subject to 
the following two conditions: (1) this device may not cause harmful 
interference, and (2) this device must accept any interference received 
including interference that may cause undesired operation.
