For Customers in the U.S.A. 

and Canada

This equipment complies with FCC 

radiation exposure limits set forth for an 

uncontrolled environment and meets 

the FCC radio frequency (RF) Exposure 

Guidelines. This equipment has very 

low levels of RF energy that is deemed 

to comply without testing of specific 

absorption rate (SAR).
The available scientific evidence does 

not show that any health problems 

are associated with using low power 

wireless devices. There is no proof, 

however, that these low power wireless 

devices are absolutely safe. Low power 

Wireless devices emit low levels of radio 

frequency energy (RF) in the microwave 

range while being used. Whereas high 

levels of RF can produce health effects 

(by heating tissue), exposure of low-level 

RF that does not produce heating effects 

causes no known adverse health effects. 

Many studies of low-level RF exposures 

have not found any biological effects. 

Some studies have suggested that some 

biological effects might occur, but such 

findings have not been confirmed by 

additional research.
This equipment has been tested and 

found to comply with ISED radiation 

exposure limits set forth for an 

uncontrolled environment and meets 

RSS-102 of the ISED radio frequency (RF) 

Exposure rules.

Supplier’s Declaration of Conformity

Trade Name : SONY
Model : WW734234

Address : 16535 Via Esprillo, San Diego, 

CA 92127 U.S.A.
Telephone Number : 858-942-2230
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.

Important note on use of 5 GHz wireless 

LAN

Compliance with FCC requirement 

15.407(c)
Data transmission is always initiated 

by software, which is the passed down 

through the MAC, through the digital and 

analog baseband, and finally to the RF 

chip. Several special packets are initiated 

by the MAC. These are the only ways 

the digital baseband portion will turn on 

the RF transmitter, which it then turns 

off at the end of the packet. Therefore, 

the transmitter will be on only while one 

of the aforementioned packets is being 

transmitted. In other words, this device 

automatically discontinue transmission in 

case of either absence of information to 

transmit or operational failure.

Frequency Tolerance: ±20 ppm

For Customers in Canada

5 150-5 350 MHz band is restricted to 

indoor operation only.

High-power radars are allocated as 

primary users (i.e. priority users) of the 

bands 5 250-5 350 MHz and 5 650-

5 850 MHz and that these radars could 

cause interference and/or damage to 

LE-LAN devices.
