For your better understanding of this manual, please read the following conventions first.   
1.1 Instructional Conventions 
Icon Description  
Note  Indicates references that can further describe the related topics.   
Caution  Indicates situations that could cause data loss or equipment damage.   
1.2 Notational Conventions 
Convention Description

The quotation marks enclose the name of a software interface element. For 
example, click “OK”. 
Bold
The text in boldface denotes the name of a hardware button. For example, press 
the PTT key.   
->
The symbol directs you to access a multi-level menu. For example, to select 
“New” from the “File” menu, we will describe it as follows: “File -> New”.

Group Call  A half-duplex call initiated by an individual user to a group.   

Document Conventions  Owner’s Manual

Term Description  
Half-duplex 
Half-duplex communication is also called “two-way alternate communication”. It 
indicates the communication is provided in both directions, but only one direction at 
a time, that is, only one party is allowed to transmit or receive at a time.   
Full-duplex  
Full-duplex communication is also called “full-duplex synchronous communication”. 
It indicates the communication is allowed in both directions simultaneously, that is, 
both parties can transmit and receive at the same time.   
Direct Mode 
Operation 
(DMO)
DMO supports half-duplex operation and allows the terminals to communicate 
directly with each other, without using a TETRA network infrastructure. Thus 
functions that require network access, such as telephone call, will be unavailable.   
Trunked Mode 
Operation 
(TMO)
TMO supports either half-duplex or full-duplex operation and allows the terminals to 
communicate with each other via the TETRA network. Thus functions that require 
network access are available. To operate in TMO mode, the terminal must be 
granted authorization by your service provider, and must stay within the network 
coverage.

4.1 Installation
4.1.1 Installation Instructions   
z  This terminal is designed for a 10.8–15.6V (typical: 13.2V) negative ground electrical system. Please 
check the ground polarity and voltage of the vehicle power supply before you install this terminal.   
z  Plan a proper position to ensure sufficient space for heat dissipation, thus avoiding unexpected 
damage to other equipments in the vehicle due to overheating of the terminal that operates under 
high current.   
z  It is suggested to route the antennas and power cords in a concealed way, so that the driver can 
access the controls and operate easily.

12.1 SSI&TSI Dialing Rules   
In the TETRA system, subscribers are distinguished by different identities. Each subscriber is assigned 
with a unique short subscriber identity (SSI), which serves a part of the TETRA subscriber identity (TSI). 
And TSI is generally composed in this way: Mobile Country Code (MCC) + Mobile Network Code (MNC) 
+ SSI. To initiate an individual call, please dial the SSI or TSI in compliance with the rules below.     
z SSI Dialing  
Make sure there are not more than 8 digits.   
z TSI Dialing  
¾MNC+SSI:
1) Input the MNC as it is;   
2) SSI must be 8 digits long. Add 0 before the first digit of SSI which is shorter than 8 digits.   
For example, when MNC is 20 and SSI is 504, you need to input 2000000504.   
¾MCC+MNC+SSI:  
1) MCC must contain 3 digits. Add 0 before the first digit of MCC which is shorter than 3 digits; 
2) MNC must contain 4 or 5 digits. When the MNC is shorter than 4 digits, add 0 before its first 
digit; when it is 5 digits long, use it directly;   
3) SSI must be 8 digits long. Add 0 before the first digit of SSI which is shorter than 8 digits.   
For example, when MCC is 460, MNC is 20 and SSI is 504, you need to input 460002000000504.
