Waste Electrical and Electronic Equipment (WEEE) Directive

In the European Union and the United Kingdom, this label indicates that this product should not be disposed of with household 

waste. It should be deposited at an appropriate facility to enable recovery and recycling.

Federal Communications Commission RF Exposure Notice:

Antennas used for the purpose of radiating signals are limited to a maximum gain of 14 dBi. Each antenna must be positioned 

to observe minimum separation requirements from all users and bystanders. The following guidelines should be used when 

considering separation distances.

Antennas must be placed such that, under normal conditions, personnel cannot come within 72 cm (~2.5 ft.) from any antenna. 

Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF exposures beyond the 

maximum permissible limit as defined by 47 CFR 1.1310, i.e., limits for General Population/Uncontrolled Exposure.

WARNING: 

Voltages in this equipment are hazardous to life. No user­serviceable parts inside. Refer all servicing to qualified service personnel. The safety cer­

tifications do not apply when the operating voltage is changed from the factory setting.

Note: 

Use only with the included power supply or a Shure-approved equivalent.
