Hearing Aid Compatibility (HAC)
The CN4 conforms to the FCC rules and ANSI C63.19:2007, and is rated T3 and M3 with the rating statement located on its box.
The Hearing Aid Compatibility Act of 1988 (HAC Act) requires digitial wireless phones to be compatible with hearing-aids to
ensure reasonable access to telecommunications services for persons with hearing disabilities.
Some hearing devices (hearing aids and cochlear implants) used near some wireless phones may detect interference with buzzing,
humming, or whining noise. Some hearing devices are more immune than others to that noise and phones also vary in the amount
of interference they generate. Results will vary depending on the user’s hearing device and hearing loss. If your hearing device is
vulnerable to interference, even a rated phone may not be used successfully.
A rating system developed by the Alliance for Telecommunications Industries Solutions (ATIS) for wireless phones is intended to
assist hearing device users find phones that may be compatible with their hearing devices. Not all phones have been rated. Phones
rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices, where M4 is the better/
higher rating. Phones rated T3 or T4 meet FCC requirements and are likely to be more useable with a hearing device’s telecoil
(T Switch or Telephone Switch), if so equipped, compared to unrated phones, where T4 is the better/higher rating. To check
compatibility of your hearing device with this wireless device, the numeric rating values of your hearing device and this wireless
device should be added together. A sum of 5 is acceptable for normal use and a sum of 6 or higher is better.
Important Radio Information
The CN4 complies with Parts 15, 22, and 24 of the FCC rules and with RSS-132, -133, and -210 of Industry Canada. 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 can cause undesired operation.
This equipment complies with the FCC and Industry Canada RSS-102 radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operation instruction for satisfying RF exposure compliance. Please follow
operation instructions as documented for this product.
This product meets the RF exposure guidelines when used with the Intermec accessories supplied or designated for this product.
Use of other accessories may not ensure compliance with RF exposure guidelines. When installing and using this product within a
20-cm (8-inch) distance (per MPE calculation) from the CN4 to the body or head of the user or nearby persons, the time duration
of such exposure must be minimized to protect the user from harmful RF radiation effects. The antenna must not be touched
during transmitter operation.
Specific Absorption Rate (SAR) Information
This product has been tested and meets the FCC RF exposure guidelines when used with the Intermec accessories supplied or
designated for this product. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. For residents
of Canada and the United States and other countries/regions that have adopted the SAR limit recommended by the Federal
Communications Commission Office of Engineering and Technology (OET) Bulletin 65C and Industry Canada RF exposure
standard RSS-102, the maximum allowed SAR value is 1.6 W/kg over 1 g of tissue.
Radio Frequency (RF) Exposure and Specific Absorption Rate (SAR) Test Results for Intermec Model CN4:
Simultaneous radios 1.067 W/kg (SAR-to-Peak Location Separation Ratio, antenna to antenna)
UMTS/HSPA Radio 0.684 W/kg (maximum SAR value tested at the ear)
0.939 W/kg (maximum SAR value tested for body-worn operation)
802.11b/g radio 0.784 W/kg (maximum SAR value tested at the ear)
0.078 W/kg (maximum SAR value tested for body-worn operation)
Bluetooth radio Negligible due to very low output power.
