Battery Advisory - AT&T MiFi Liberate User Manual

Battery Advisory

As with any battery-operated mobile device being used for a certain amount of time, the MiFi
•
Liberate device can get warm to the touch. This is normal and within standard specifications,
and poses no hazard.
The MiFi Liberate device is configured to automatically stop charging and disconnect the
•
battery if the temperature rises above a set threshold. When the temperature falls below that
threshold, the battery reconnects and the unit starts charging again.
Always use Novatel Wireless original batteries and chargers.
•
It normally takes at least four hours to fully charge the battery. If the device is in use the
•
battery may take longer to charge.
Do not use sharp objects to access the battery well; this may damage the device and the
•
battery.
Do not use excessive force to remove the battery or to access the battery well.
•
Battery life depends on the network, signal strength, temperature, features, and accessories
•
you use.
New batteries or batteries stored for a long time may take more time to charge.
•
When charging your battery, keep it near room temperature.
•
When storing your battery, keep it uncharged in a cool, dark, dry place.
•
Never expose batteries to temperatures below 0°C (32°F) or above 45°C (113°F).
•
Never leave the device in an unattended vehicle due to uncontrollable temperatures that
•
may be outside the specified temperature for this device.
Some batteries perform best after several full charge/discharge cycles.
•
It is normal for batteries to gradually wear down and require longer charging times. If you
•
notice a change in your battery life, it is probably time to purchase a new battery.
Avoid placing the device on vibrating surfaces for long period of time (such as a washer or
•
dryer).
Avoid placing the device near 802.11-radiating devices such as microwave ovens and 2.4 GHz
•
cordless telephones.
Do not place the device in a closed space where there is no air circulation (e.g., do not wrap
•
the device in a blanket or place it under a pillow).
Whenever you remove or insert either the battery or the SIM card, ensure your MiFi Liberate
•
device is not connected to any device or power source.
Never use tools, knives, keys, pens or any type of object to force the door open or to remove
•
the battery. Using any of these types of objects could result in puncturing the MiFi Liberate
device battery.
Battery disposal: Contact your local recycling center for proper battery disposal.
•
In the event of a battery leak: Do not allow the liquid to come in contact with skin or eyes. If
•
contact is made, wash the area with large amounts of water and seek medical advice.
