							1. INTRODUCTION
The frequency-synthesized SABER Handie-Talkie
portable radios are advanced-design, microcomputer-
based transceivers that incorporate the latest technol-
ogy available in two-way radio communications. All
channel frequencies and squelch codes are stored in
an electrically erasable, programmable read-only
memory (EEPROM), with all transmit and receive
operations controlled by a microcomputer.
The functions provided by the radio are identified
by the model and option numbers as illustrated by the
model and option charts at the front of this manual.
Model and option numbers will be shown on the
radios customer information sheet, which is shipped
with each new radio.
a. Physical Description
The channel selector switch, on/off/volume con-
trol, multifunction LED, antenna, coded/clear selector
switch (optional) and emergency button (optional) are
located on top of the radio. The PTT switch, monitor
button, and repeater access (RAT) buttons are located
on the left side of the radio (viewed from the front),
and the display and keypad (SABER II and III models)
are an integral part of the front cover. On the back of
the radio are the rf connector and universal connector.
The SABER radio is small in size and weight, and
constructed of a highly durable, impact resistant,
molded polycarbonate-blend housing. O-rings and
seals are used throughout the radio. All controls,
including the PTT switch, the monitor button, and the
keypad are weather resistant, and the microphone
and speaker are covered with a special diaphragm to
provide extra resistance against dirt, dust, and water
intrusion. This proven rugged construction offers
excellent protection against adverse environmental
conditions. 
The total radio height is determined by the battery
size and whether the radio is a SECURENET model.
All other dimensions are standard.
b. Electrical Description
Electrically, the radio can be divided into two basic
sections: the main radio board and, on SABER II and
III radios, the display board. The main radio board
performs the transmit and receive, frequency genera-
tion and distribution, power generation and distribu-
tion, control, and interface functions.
The display board includes circuitry for displaying
user information, an electrically-erasable read-only
memory (EEPROM) for storage of user-programmable
parameters, and a dual-tone, multi-frequency (DTMF)
GENERAL DESCRIPTION
generator.
2. STANDARD FEATURES
The SABER radio has an internal microphone and
speaker, but can be operated with an optional external
microphone and/or speaker. External rf and univer-
sal connectors provide easy access for testing, and
for attaching a remote antenna and a variety of audio
accessories. Radio models are available with up to
120 channels of carrier, tone Private-Line (PL),
and/or Digital Private-Line (DPL) squelch operation.
The type of squelch is enabled on a per-channel basis
with up to 16 code pairs available per radio. Two
power output levels are offered: medium power (1 watt
on mid-band models, 2.5 watts on vhf models, and 2
watts on uhf models), and high power (6 watts on mid-
band and vhf models, and 5 watts on uhf models).
The battery slides onto the bottom of the radio and
is held in place by a spring-loaded latch. Batteries are
available in three different sizes, which correspond to
the battery capacity (light, medium, and ultra-high).
The different size batteries affect the operating time
between charges, and the overall height and weight of
the radio.
A red multifunction LED on the top of the radio pro-
vides feedback to the user. The LED indicates when
the radio is in transmit (continuous red), a low battery
condition (flashing red in SABER I radios only), or
channel busy (SABER II and III radios and SABER I
radios with the channel busy option).
3.  SPECIAL STANDARD FEATURES
a. Field Programming
The SABER radio uses a reprogrammable 
EEPROM, which permits operating characteristics to
be changed without opening the radio. Programming
is accomplished via a programming cable interface 
to an IBM PC, Laptop PC, or Personal System/2 
computers.
b. Multiple Digital Private-Line (DPL) And Tone
Private-Line (PL) Coded Squelch
Coded squelch allows only those calls with a
radios particular code to be heard, and can be
enabled on a per-channel basis. Thus, a SABER radio
can have carrier squelch on some channels, DPL
squelch on others, and tone PL squelch on others.
You can choose from among 80 DPL codes and 28
tone PL codes.
c. SECURENET™ Radios
The SABER SECURENET radios can operate in
either the secure coded voice mode, or the standard
clear voice mode. The mode used for transmission
