Compliance information

Exposure to radio frequency signals

The BlackBerry smartphone radio is a low power radio transmitter and receiver. When the BlackBerry
smartphone radio is turned on, it receives and also sends out radio frequency signals. The BlackBerry
smartphone is designed to comply with Federal Communications Commission (FCC), Ministry of Internal
Affairs and Communications (MIC), and Industry Canada (IC) guidelines respecting safety levels of radio
frequency exposure for wireless devices, which in turn are consistent with the following safety standards
previously set by Canadian, U.S., and international standards bodies:

• ANSI/IEEE C95.1, 2005, American National Standards Institute/Institute of Electrical and Electronics
Engineers Standard for Safety Levels with Respect to Human Exposure to Radio Frequency
Electromagnetic Fields, 3 kHz to 300 GHz

• National Council on Radiation Protection and Measurements (NCRP) Report 86, 1986, Biological
Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields

• Health Canada, Safety Code 6, 2009, Limits of Human Exposure to Radiofrequency Electromagnetic
Fields in the Frequency Range from 3 kHz to 300 GHz

• EN 50360, 2001+A1:2012, Product standard to demonstrate the compliance of mobile phones with
the basic restrictions related to human exposure to electromagnetic fields (300 MHz to 3 GHz)

• International Commission on Non-Ionizing Radiation Protection (ICNIRP), 2009, Guidelines for
Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic fields (up to 300 GHz)

• Official Journal of the European Union (OJEU), 1999, Council Recommendation of 12 July 1999 on
the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz)

• MIC, 2001, Article 14-2 of the Ordinance for Regulating Radio Equipment

To maintain compliance with FCC, IC, MIC, and EU radio frequency exposure guidelines when you carry the
