Warning: Changes or modifications to this device not expressly approved by Zaxcom Inc. could void the user’s authority to operate the equipment. 

 

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, 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 instructions, 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 or 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. 

 

RF Exposure: 

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment is in direct contact with 

the body of the user under normal operating conditions. This transmitter must not be co-located or operating in conjunction with any other 

antenna or transmitter. 

 

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved 

for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen 

that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. 

 

Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain 

maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à 

l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) 

ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. 

 

This radio transmitter (contains the module PR6-XRT) and has been approved by Industry Canada to operate with the antenna types listed 

below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in 

this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. 

 

Quarter Wave Whip Antenna, 5.19dBi gain, 50 Ohms 

 

Le présent émetteur radio (PR6-XRT) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et 

ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont 

le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.

NOTICE:

 

Most users do not need a license to operate a wireless microphone system. Nevertheless, operating a microphone system without 

a license is subject to certain restrictions: 

the system may not cause harmful interference, 

it must operate at a low power level (not in excess of 50 milliwatts), 

it has no protection from interference received from any other device. 

 

Purchasers should also be aware that the FCC is currently evaluating the use of wireless microphone systems, and these rules are 

subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless 

microphone website at: 

www.fcc.gov/cgb/wirelessmicrophones.

To operate wireless microphone systems transmitting with 

greater than 50mW of radiated power, you must qualify as a Part 74 user and be licensed.
