1.2. Terms and Abbreviations
Router –iRZ router.
3G –General name for a set of standards describing the operation in UMTS and GSM networks like GPRS,
EDGE, HSPA.
Server –This term may be used to describe:
the server part of a software package used by a computer system,
the role of a component or an object in the structural and functional design of a technical solution
deployed with the use of the router,
a computer providing particular services (network services, data processing and storing services, etc.)
Technical Solution –An idea or a document describing a set of technical measures and/or procedures aimed
at solving a particular problem; this is implemented through involving functionalities of components of such a
technical solution which are interrelated and interacting in a particular way.
Public IP address –An Internet IP address assigned by an Internet service provider to the customer for use
on the provider's or the client's equipment for direct connection with the customer's equipment through the
Internet.
Static Public IP Address –A public IP address which can not be changed under any circumstances (change
in client's equipment type, etc.) or in any event (reconnection to the provider's network, etc.); static IP address
can only be changed through submission of a relevant application to the Internet service provider.
Authentication –The procedure of user/client/host authenticity verification by comparing details provided by
them at connection with the details correlating with the username/login in the database.
Router Web Interface –An administration tool built in the router to control and configure its functions and to
monitor the state of these functions.
Remote Device (Remote Host) –A device physically removed from the location or facility/host which is
under discussion in a particular context.

2. Information on Device
2.1. Purpose
The router is a multipurpose radio communication user device operating in mobile networks. The router is
capable of data transmitting, receiving and protecting and supporting computer network. Support of
UMTS/HSPA+/EDGE/GPRS provides highspeed access to Internet. The main feature of these routers is Wi-Fi
hotspot (IEEE 802.11b/g/n standart base), that provides wireless internet connection for other devices.

2.7. Safety Precautions
Limitations to the router use in proximity of other electronic devices:
Switch off the router in hospitals or in proximity of medical equipment (for example, cardiac pacemakers,
hearing aid devices) as it may interfere with medical equipment
Switch off the router in aircraft and take measures to prevent its accidental switching on
Switch off the router in proximity of fueling stations, chemical facilities, areas of blasting operations The
router may interfere with equipment; at short distances it may also interfere with TV and radio sets.
Protect the router against dust and moisture.
Observe the permissible levels of power supply and vibration at the place of router installation.
