Hytera Communications MT680F4 TETRA Mobile Terminal User Manual
Hytera Communications Corporation Ltd. TETRA Mobile Terminal
User Manual
Preface
Thank you for purchasing Hytera MT680 TETRA digital mobile
terminal. MT680 is equipped with a large transflective TFT color
display and a built-in GPS module, and can operate in both TMO
and DMO modes. The benefits that this terminal can deliver will
dramatically improve your working efciency.
To derive optimum performance from the terminal, please read the
Safety Information Booklet and Owner’s Manual carefully before
use.
Telephone Call
Telephone call is usually a full duplex call initiated between
the terminal and a PSTN subscriber (such as telephone
user or mobile phone user).
To send or receive telephone calls, the mobile terminal
must operate in TMO mode, and must be authorized to
access public network through PSTN gateway. Telephone
call is a network service. For more details and availability
of the service, please contact your service provider.
Emergency Call
Emergency call has the highest priority, and is very helpful
for the user to request help when emergency occurs.
Generally, it is set to group call type. Emergency call can
break off any non-emergency calls in progress.
DMO (Direct Mode Operation)
DMO mode allows the terminals to communicate directly
with each other in simplex mode, without network
restriction. But functions that require network access, such
as telephone call and short message, will be disallowed.
TMO (Trunked Mode Operation)
TMO mode allows the terminals to communicate with
each other via the TETRA network, in half duplex or full
duplex mode. Functions that require network access are
supported.
Icon Information
The following icons are available through this manual:
Caution: indicates situations that could cause
damage to your terminal.
Note: indicates tips that can help you make
better use of your terminal.
Term Explanation
Key Operation
Short press: to press a key and release it quickly.
Long press: to press and hold down a key for above 2.5
seconds.
Hold down: to press a key and remain holding it down.
Individual Call
Individual call is a simplex or duplex call initiated by a
single user to another user, involving the calling party and
the called party only.
Group Call
Group call is a simplex call initiated by a single user to a
group of users, involving the calling party and all the group
members.
To operate in TMO mode, the terminal must be granted
authorization by your service provider, and must be within
the network coverage.
Full Duplex
Full duplex allows the ability to communicate in both
directions simultaneously.
Half Duplex
Half duplex, also known as simplex, allows the ability to
communicate in only one direction, at a time. Two-way
communication is possible, but not simultaneously.

standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at operating duty factors of up to 50%
transmitting and is authorized by the FCC for occupational use only. In terms of measuring
RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable
RF energy only while it is transmitting (during talking), not when it is receiving (listening) or
in standby mode.
● The device complies with SAR and/or RF field strength limits of RSS-102 requirement
Your radio complies with the following of RF energy exposure
standards and guidelines

● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
● To ensure optimal performance and compliance with the occupational/controlled environment
RF energy exposure limits in the above standards and guidelines, users should transmit no
more than 50% of the time and always adhere to the following procedures:
● Gain of antenna must not exceed 5.5dBi.
● Antenna Installation: Install the mobile antenna at least 108 cm away from your body, in
accordance with the requirements of the antenna manufacturer/supplier.
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) key; to receive, release the PTT key.

FCC Licensing Information
Part 15 Compliance
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. 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 and 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:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
● Consult the dealer or an experienced radio/TV technician for help.
Note:“Changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.”

Appendix 2 SSI&TSI Dialing Rules
This terminal supports these dialing methods: SSI&TSI,
PABX and PSTN. Each method shall follow a specific
dialing rule. Currently, this terminal is only capable of
checking SSI&TSI dialing rule:
For target number less than 8 digits, input it directly;
For example, when MCC = default value, MNC =
default value and ISSI = 504, you just need to input
504 to make the call;
For target number with 9-13 digits, input MNC+ISSI,
where ISSI must be 8 digits long. Add 0 before
the first digit to supplement the balance when it is
less than the said length. For MNC, input it as it is.
For example, when MCC=default value, MNC=20 and
ISSI=504, you need to input 2000000504 to make the
call;
For target number over 13 digits, input
MCC+MNC+ISSI, where ISSI must be 8 digits long,
MNC must be 4 or 5 digits long and MCC must be 3
digits long. Add 0 before the rst digit to supplement the
balance when any of them is less than the said length.
For example, when MCC = 460, MNC = 20 and ISSI =
504, you need to input 4600002000000504 or to make
the call.
Note: MCC stands for Mobile Country Code, MNC
