However, when using your phone equipment, safety instructions should be followed to avoid the risks of fire, electric shock, injury to person, and damage to property. General Safety Instructions 1. When using your wireless phone, ensure your safety and the safety of others: a. Always watch where you are walking and standing. b. Don’t let a phone call distract you from working safely. c. If power goes out, it won’t work. Recommend backup power. 2. In an emergency: a. If an emergency occurs, dial the emergency phone number. Remember: if you are in an area where your phone does not have a clear signal from the base, it is highly probable that the call may not go through. Locate the nearest landline telephone or other communications device to call for help. b. Emergency calls may not automatically provide emergency personnel with your name, phone number or location. 3. Notice to Hearing Aid Users: This phone system is compatible with inductively coupled hearing aids. 4. Notice to Cardiac Pacemaker Users: Preliminary studies done by the US FDA and others have shown that, although interference to the implanted cardiac pacemaker may occur when operating very closely, wireless telephones “do not seem to pose a significant problem for pacemaker wearers.” However, until more is known, FDA suggests that people with pacemakers may want to take precautions when using or carrying a wireless telephone to ensure that there is ample distance between the telephone and the pacemaker. Do not carry the handset in a breast pocket. If you have any reason to suspect that interference is taking place, turn off your handset immediately.
