Safety
To optimize safety and expedite installation and service, read this document thoroughly. Follow
all warnings, cautions, and instructions marked on the equipment and included in this document.
To aid in the prevention of injury and damage to property, cautionary symbols have been placed
in this document to alert the reader to known potentially hazardous situations, or hazards to
equipment or procedures. The symbols are placed before the information to which they apply.
However, any situation that involves heavy equipment and electricity can become hazardous, and
caution and safety should be practiced at all times when installing, servicing, or operating the
equipment.
Caution Symbol - possible equipment or property damage
Warning Symbol - could cause personal injury or otherwise be hazardous to
your health
Navini Networks, Inc., expressly requires that when using Navini electronic equipment always
follow the basic safety precautions to reduce the risk of electrical shock, fire, and injury to
people and/or property.
1. Follow all warnings and instructions that come with the equipment.
2. Do not use the equipment while you are in a bathtub, shower, pool, or spa. Exposure of the
equipment to water could cause severe electrical shock or serious damage to the equipment.
3. Do not allow any type of liquid to come in contact with the equipment. Unplug the
equipment from the power source before cleaning. Use a damp cloth for cleaning. Do not use
any soaps or liquid cleaners.
4. Follow all airport and FAA regulations when using the equipment on or near aircraft.
5. Only operate the equipment from the type of power source(s) indicated in this manual (110
VAC or Navini supplied battery). Any other type of input power source may cause damage to
the equipment.
6. Power the equipment using only the battery or the AC adapter cable provided, and in
accordance with the instructions specified in the User Guide.
7. Do not use a frayed or damaged power cord. Do not place the power cord where it can be
stepped on or tripped over.
8. Do not touch wires where the insulation is frayed or worn unless the equipment has been
disconnected from its power source.
9. Do not overload wall outlets, power strips, or extension cords. This can cause serious
electrical shock or fire.
10. Do not place the equipment on an unstable surface. It can fall and cause injury or damage to
the equipment.

11. Do not disassemble the equipment. Removing covers exposes dangerous voltages or other
risks and also voids the warranty. Incorrect reassembly can cause equipment damage or
electrical shock. Only an authorized repair technician should service this product.
12. Do not expose the equipment to extreme hot or cold temperatures.
13. Do not use the equipment under the following conditions:
• When the equipment has been exposed to water or moisture.
• When the equipment has been damaged.
• When the power cord is damaged or frayed.
• When the equipment does not operate properly or shows a distinct
change in performance.

Regulatory Information
FCC Notice
WARNING! This device is a Radio Frequency transmitter. It is required to comply with
FCC RF exposure requirements for transmitting devices. A minimum separation distance
of 8 inches (20 cm) or more must be maintained between the antenna and all persons
during device operations to ensure compliance with the FCC’s rules for Radio Frequency
Exposure. If this minimum distance cannot be maintained, exposure to RF levels that
exceed the FCC’s limits may result.
FCC Compliance and Advisory Statement
This equipment has been tested and found to comply with the limits for a class B digital
device, Pursuant to Part 15 of the FCC rules. The operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed or used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
(1) Reorient or relocate the receiving antenna;
(2) Increase the separation between the equipment and the receiver;
(3) Connect the equipment to an outlet on a circuit different from that to which the
receiver is connected;
(4) Consult the dealer or an experienced radio/TV technician for additional suggestions.
INFORMATION TO USER
This device has been authorized as a radio frequency transmitter under the appropriate
rules of the Federal Communications Commission. Any changes or modifications not
expressly approved by Navini Networks could void the user’s authority to operate the
equipment.

Battery Caution & Procedures
WARNING! To reduce risk of injury or fire, follow these instructions when handling the
battery.
1. Risk of explosion is possible if the battery is replaced with one not supplied by Navini
Networks.
2. Do not dispose of the battery in a fire. It may explode. Check with the local codes for
battery disposal guidelines.
3. Do not open or mutilate the battery. The battery contains substances that are toxic,
corrosive, or harmful to humans. If battery substances come in contact with the skin,
seek medical help immediately.
4. Do not attempt to recharge the battery by any means except per the instructions in this
manual.
5. Remove the battery from the equipment if the equipment is not going to be used for a
long period of time. The battery could leak and cause damage to the equipment.
6. Exercise care when handling the battery to prevent shorting the battery with conducting
materials such as bracelets, rings, and keys.
7. Store the battery pack in a dry place, 0 to +40 degrees Celsius.
8. Dispose of used batteries according to environmental guidelines.

A protocol that allows mobile users to send text-based messages
from one device to another. The text appears on a device’s screen
and may be a maximum 160 characters in length.
2
A Windows
T process that allows a network administrator to inventory all
hardware and software on the network, then perform software
distribution over the LAN.
Simple Network Management
Protocol
Standard management request-reply protocol for managing
TCP/IP networks. A device is said to be SNMP compatible if it
can be monitored or controlled using SNMP messages.
Signal-to-noise Ratio Related to RSSI, a measurement of the intended signal being
transmitted against the other entities that can interfere with the
signal.
Small Office/Home Office Small, remote office with a MAN or WAN connection back to a
larger corporate network and/or the Internet.
Signal Strength Indicator See “RSSI”.
Software Computer instructions or data.
Synthesizer Card A circuit card in the Navini BTS digital shelf that provides a
local oscillator and system clock with a single calibration
transceiver. The card is used to calibrate the Base Station so that
no external spectrum analyzer or signal generator is required.
Synchronous Digital packets or signals that are sent at the same, precisely
1
Traffic Channel or 2Transmission
Control Code
clocked fixed rate of speed.
1
A portion of a radio channel used to enable transmission of one
direction of a digitized voice conversation (as opposed to the
Voice Channel).
2
A way of segregating traffic in order to define
controlled communities of interest among subscribers.
Transport Control Protocol A standardized transport protocol between IP-based network
nodes that allows two hosts to establish a connection and
exchange streams of data. TCP operates on top of Internet
Protocols and handles the multiplexing of sessions, error
recovery, reliability and flow; it guarantees packets are delivered
in the same order in which they were sent.
Transport Control
Protocol/Internet Protocol
A set of protocols that allows cooperating computers to share
resources across the network. TCP provides the reliability in the
transmission, while IP provides connectionless packet service.
