Nokia T21 User Manual - Page 33

Nokia T21 User Guide Replace the battery only with another battery that has been qualified with the system per this standard, IEEE-Std-1725. Use of an unqualified battery may present a risk of fire, explosion, leakage or other hazard. Avoid dropping the device or battery. If the device or battery is dropped, especially on a hard surface, and the user suspects damage, take it to a service center for inspection. Improper battery use may result in a fire, explosion or other hazard. To unplug a charger or an accessory, hold and pull the plug, not the cord. Additionally, the following applies if your device has a removable battery: • Always switch the device off and unplug the charger before removing the battery. • Accidental short-circuiting can happen when a metallic object touches the metal strips on the battery. This may damage the battery or the other object. SMALL CHILDREN Your device and its accessories are not toys. They may contain small parts. Keep them out of the reach of small children. MEDICAL DEVICES Operation of radio transmitting equipment, including wireless phones, may interfere with inadequately shielded medical devices' function. Consult a physician or the medical device's manufacturer to determine if it is adequately shielded from external radio energy. IMPLANTED MEDICAL DEVICES To avoid potential interference, manufacturers of implanted medical devices (such as cardiac pacemakers, insulin pumps, and neurostimulators) recommend a minimum separation of 15.3 centimeters (6 inches) between a wireless device and the medical device. Persons who have such devices should: • Always keep the wireless device more than 15.3 centimeters (6 inches) from the medical device. • Not carry the wireless device in a breast pocket. • Hold the wireless device to the ear opposite the medical device. • Switch the wireless device off if there is any reason to suspect that interference is taking place. • Follow the manufacturer directions for the implanted medical device. If you have any questions about using your wireless device with an implanted medical device, consult your health care provider. © 2022 HMD Global Oy. All rights reserved. 33
