Quatech Serial Device Server User Manual

This equipment has been tested and found to comply with the limits for a 

Class A digital device, pursuant to part 15 of the FCC Rules. These limits 
are designed to provide reasonable protection against harmful 

interference when the equipment is operated in a commercial 
environment. 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. Operation of this equipment in a residential area is 

likely to cause harmful interference in which case the user will be 

required to correct the interference at his own expense. 

The user is cautioned that changes and modifications made to the 

equipment without approval of the manufacturer could void the user’s 

authority to operate this equipment. 

 

It is suggested that the user use only shielded and grounded cables to 

ensure compliance with FCC Rules. 
Caution: To comply with FCC RF exposure compliance requirements, a 
separation distance of at least 20 cm must be maintained between the 

antenna of this device and all persons. 

 

This device complies with Industry Canada ICES-003 regulations.    

Cet appareil est conformé à la norme ICES-003 du Canada. 
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. 

 
To prevent radio interference to the licensed service, this device must be 

operated indoors only and should be kept away from windows to provide 
maximum shielding. 

 

This device has been designed to operate with an antenna having a 
maximum gain of 2.2 dBi. Antennae having a higher gain are strictly 

prohibited per regulations of Industry Canada. 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. 

 
The installer of this radio equipment must ensure that the antenna is 

located or pointed such that it does not emit RF field in excess of Health 
Canada limits for the general population.
