Cordless telephone privacy
Cordless telephones are radio devices. Communications between the handset and base of your cordless telephone are accomplished by means of radio waves which are  broadcast over the open airways. Because of the inherent physical properties of radio waves, your communications can be received by radio receiving devices other than your own cordless telephone unit. Consequently, any communications using your cordless telephone may not be private.
Emergency calling service
(i.e., 911, 999, etc.) with VoIP typically functions the same as that of traditional phone service companies. However, you are strongly advised to consult your VoIP provider to ensure that emergency service via VoIP is available in your area. In addition, you will likely be asked to register your physical address with your VoIP service provider to ensure that an emergency response team is able to locate the origin of the emergency call. Also note that it may take several days for the registration of your address to take effect.
In order to better ensure your safety, please be aware of certain circumstances in which emergency calling service may be either unavailable or limited in comparison to traditional emergency calling services.

  • During an electrical power outage, an internet service outage, or a service disruption due to non-payment, your emergency calling service may not function properly.
  • If at any point in time your broadband phone or adapter fails, emergency calling service may not function properly.
  • The relocation of your base station to a physical address other than that provided upon signup, or the use of a number outside your normal area code or exchange may cause incorrect emergency calling information to be provided to your local emergencyresponse center.
  • Please contact your VoIP service provider for more information.

Please be advised that emergency calling services generally do not recommend programming emergency numbers into the phone’s speed dial as this may lead to accidental dialing. If you dialed an emergency number in error, do not terminate the call. Stay on the phone and explain to the dispatcher that you dialed by accident and that you do not have an emergency.

Health and safety information FCC
Exposure to Radio Frequency (RF) Signals
Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on the safety standards previously set by both U.S. and international standards bodies:
This product has been shown to be capable of compliance for localized specific absorption rate (SAR) for uncontrolled environment/general population exposure limits specified in ANSI/ IEEE Std. C95.1-1992 and has been tested in accordance with the measurement procedures specified in FCC/OET Bulletin 65 Supplement C (2001) and IEEE Std. 1528-2003 (December 2003).
RF exposure FCC
Tests for SAR are conducted using standard operating positions specified by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operation can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a phone model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government-adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. Body-worn measurements may differ among phone models, depending upon available accessories and FCC requirements.
The highest SAR value for this phone when tested for use at the ear is 0.41 W/kg. While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure. For body worn operation, to maintain compliance with FCC RF exposure guidelines, use only accessories that contain no metallic components and provide a separation distance of 15mm (0.6 inches) to the body. Use of other accessories may violate FCC RF exposure guidelines and should be avoided.
