in any way. If a battery leaks, do not let liquid touch skin or eyes. If this
happens, immediately flush the affected areas with water, or seek medical
help. Do not modify, attempt to insert foreign objects into the battery, or
immerse or expose it to water or other liquids. Batteries may explode if
damaged.
Use the battery and charger for their intended purposes only. Improper use, or
use of unapproved or incompatible batteries or chargers may present a risk of
fire, explosion, or other hazard, and may invalidate any approval or warranty.

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.

PROTECT YOUR DEVICE FROM HARMFUL CONTENT
Your device may be exposed to viruses and other harmful content. Take the following precautions:
· Be cautious when opening messages. They may contain malicious software or
otherwise be harmful to your device or computer.
· Be cautious when accepting connectivity requests, browsing the internet, or
downloading content. Do not accept Bluetooth connections from sources you do
not trust.
· Only install and use services and software from sources that you trust and
that offer adequate security and protection.
· Install antivirus and other security software on your device and any
connected computer. Only use one antivirus app at a time. Using more may
affect performance and operation of the device and/or computer.
· If you access preinstalled bookmarks and links to third party internet
sites, take the appropriate precautions. HMD Global does not endorse or assume
liability for such sites.
VEHICLES
Radio signals may affect improperly installed or inadequately shielded
electronic systems in vehicles. For more info, check with the manufacturer of
your vehicle or its equipment. Only authorized personnel should install the
device in a vehicle. Faulty installation may be dangerous and invalidate your
warranty. Check regularly that all wireless device equipment in your vehicle
is mounted and operating properly. Do not store or carry flammable or
explosive materials in the same compartment as the device, its parts, or
accessories. Do not place your device or accessories in the air bag deployment
area.
POTENTIALLY EXPLOSIVE ENVIRONMENTS
Switch your device off in potentially explosive environments, such as near
gasoline pumps. Sparks may cause an explosion or fire resulting in injury or
death. Note restrictions in areas with fuel; chemical plants; or where
blasting operations are in progress. Areas with a potentially explosive
environment may not be clearly marked. These usually are areas where you are
advised to switch your engine off, below deck on boats, chemical transfer or
storage facilities, and where the air contains chemicals or particles. Check
with the manufacturers of vehicles using liquefied petroleum gas (such as
propane or butane) if this device can be safely used in their vicinity.
CERTIFICATION INFORMATION
This mobile device meets guidelines for exposure to radio waves.
Nokia T21 User Guide
Your mobile device is a radio transmitter and receiver. It is designed not to
exceed the limits for exposure to radio waves (radio frequency electromagnetic
fields), recommended by international guidelines from the independent
scientific organization ICNIRP. These guidelines incorporate substantial
safety margins that are intended to assure the protection of all persons
regardless of age and health. The exposure guidelines are based on the
Specific Absorption Rate (SAR), which is an expression of the amount of radio
frequency (RF) power deposited in the head or body when the device is
transmitting. The ICNIRP SAR limit for mobile devices is 2.0 W/kg averaged
over 10 grams of tissue.
SAR tests are carried out with the device in standard operating positions,
transmitting at its highest certified power level, in all its frequency bands.
This device meets RF exposure guidelines when used against the head or when
positioned at least 5/8 inch (1.5 centimetres) away from the body. When a
carry case, belt clip or other form of device holder is used for body-worn
operation, it should not contain metal and should provide at least the above
stated separation distance from the body.
To send data or messages, a good connection to the network is needed. Sending
may be delayed until such a connection is available. Follow the separation
distance instructions until the sending is finished.
During general use, the SAR values are usually well below the values stated
above. This is because, for purposes of system efficiency and to minimize
interference on the network, the operating power of your mobile device is
automatically decreased when full power is not needed for the call. The lower
the power output, the lower the SAR value.
Device models may have different versions and more than one value. Component
and design changes may occur over time and some changes could affect SAR
values.
For more info, go to www.sar-tick.com. Note that mobile devices may be
transmitting even if you are not making a voice call.
The World Health Organization (WHO) has stated that current scientific
information does not indicate the need for any special precautions when using
mobile devices. If you are interested in reducing your exposure, they
recommend you limit your usage or use a handsfree kit to keep the device away
from your head and body. For more information and explanations and discussions
on RF exposure, go to the WHO website at www.who.int/healthtopics
/electromagnetic-fields#tab=tab_1.
Please refer to www.hmd.com/sar for the maximum SAR value of the device.

Nokia T21 User Guide Use the Low blue light mode
Blue light is a color in the visible light spectrum that can be seen by the
human eye. Of all the colors that the human eye perceives (violet, indigo,
blue, green, yellow, orange, red), blue has the shortest wavelength and thus
produces a higher amount of energy. Since blue light passes through your eye’s
cornea and lens before reaching the retina, it may cause itchy and red eyes,
headaches, blurred vision, and poor sleep, for example. To limit and reduce
blue light, the display industry has developed solutions such as the Low blue
light mode. To switch on the Low blue light mode on your tablet, tap Settings
Display > Night Light > Turn on . If you need to look at your tablet’s screen for a long time, take frequent breaks and relax your eyes by looking at distant objects. OZO
