Proper Battery Use and Disposal
IMPORTANT
In event of a battery leak:
Do not allow the liquid to come in contact with the skin or the eyes. If contact has been
made, wash the affected area with large amounts of water and seek medical advice.
Seek medical advice immediately if a battery has been swallowed.
Communicate the appropriate steps to be taken if a hazard occurs. Due to the transmission
and reception properties of wireless communications, data occasionally can be lost or
delayed.
Please review the following guidelines for safe and responsible battery use.
Do not disassemble or open, crush, bend or deform, puncture, or shred.
Do not modify or remanufacture, attempt to insert a foreign object into the battery, immerse
or expose to water or other liquids, or expose to fire, explosion, or other hazard.
Only use the battery for the system for which it was specified.
Only use the battery with a charging system that has been qualified with the system per
this standard. Use of an unqualified battery or charger may present a risk of fire, explosion,
leakage, or other hazard.
Do not short circuit a battery or allow a metallic or conductive object to contact the battery
terminals.
Replace the battery only with another battery that has been qualified with the system per
this standard. Use of an unqualified battery may present a risk of fire, explosion, leakage, or
other hazard.
Promptly dispose of used batteries in accordance with local regulations.
Battery usage by children should be supervised.
Avoid dropping the 4G LTE Broadband Router with Voice or battery. If the 4G LTE Broadband
Router with Voice or the 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.

Glossary
1X
— The core CDMA2000 wireless air interface standard. The designation "1X", meaning 1 times Radio
Transmissio Technology, indicates the same radio frequency (RF) bandwidth as IS-95: a duplex pair of
1.25 MHz channels. The 1X standard supports packet data speeds of up to 153 kbits/s with real world
data transmission averaging 80-100 kbit/s in most commercial applications.
3G
— Third Generation. 3G refers to the third generation of mobile telephony technology. 3G
telecommunication networks support services that provide an information transfer rate of at least 200
kbit/s. However, many services advertised as 3G provide higher speed than the minimum technical
requirements for a 3G service. 3G finds application in wireless voice telephony, mobile Internet access,
fixed wireless Internet access, video calls and mobile TV.
4G LTE
— Fourth Generation Long Term Evolution. LTE is a standard for wireless data communications
technology and an evolution of the GSM/UMTS standards. The goal of LTE is to increase the capacity
and speed of wireless data networks using new DSP (digital signal processing) techniques and
modulations that were developed around the turn of the millenium. A further goal is the redesign and
simplification of the network architecture to an IP-based system with significantly reduced transfer
latency compared to the 3G architecture. The LTE wireless interface is incompatible with 2G and 3G
networks, so that it must be operated on a separate wireless spectrum.
802.11 (b, g, n)
— A set of WLAN Wi-Fi communication standards in the 2.4, 3.6 and 5 GHz frequency
bands.
bps
— Bits per second. The rate of data flow.
Broadband
— High-capacity high-speed transmission channel with a wider bandwidth than
conventional modem lines. Broadband channels can carry video, voice, and data simultaneously.
CDMA

mobile phone standards.
DHCP
— Dynamic Host Configuration Protocol. Software found in servers and routers that
automatically assigns IP addresses and other configuration data to computers, tablets, printers, and
other devices connected to the IP network.
DHCP Server
— A server or service with a server that assigns IP addresses.
DNS
— Domain Name System. A system for converting host names and domain names into IP
addresses on the Internet or on local networks that use the TCP/IP protocol.
EV-DO Rev 0
— CDMA EV-DO Rev. 0 is a leading-edge 3G wireless technology with higher data rates
and higher system capacity. It is a fully backward compatible standard and remains interoperable
with deployed EV-DO networks and devices around the world. Rev 0 provides access to mobile
devices with forward link speeds of up to 2.4 Mbit/s, and reverse link speeds up to 152 kbit/s. For more
information, visit

EV-DO Rev A
— CDMA EV-DO Rev. A is a leading-edge 3G wireless technology with higher data rates
and higher system capacity. It is a fully backward compatible standard and remains interoperable with
deployed EV-DO networks and devices around the world. Rev A provides access to mobile devices
with forward link speed of up to 3.1 Mbit/s, and reverse link speeds up to 1.8 Mbit/s. The increased
data rates on Rev. A’s physical layer enable richer applications and services. For more information, visit

operating code for the device.
GB
— Gigabyte. A multiple of the unit byte for digital information storage. Usage depends on context.
When referring to disk capacities it usually means 10
9
bytes. It also applies to data transmission
quantities over telecommunication circuits.

over the Internet.
IEEE —
Institute of Electrical and Electronics Engineers. An international technical/professional society
that promotes standardization in technical disciplines.
IMEI
— International Mobile Equipment Identity. Used in LTE networks to identify the device. It is
