2.3 Instruction of Indicator Lights
GPRS/BT is GPRS and Bluetooth red and green indicator light, red
indicator light represents GPRS module and green one represents
Bluetooth module;
RX/TX is data transmitting-receiving red and green indicator light, green
indicator light represents data receiving, red indicator light represents data
transmitting;

PWR/ALM is bi-color indicator light for normal power supply and
under-voltage, green indicator light represents normal power supply, red
indicator light represents abnormal voltage;
2.4 Bluetooth Module (Optional)
If the current radio supports Bluetooth, users can configure and query the radio
parameters by the means of Bluetooth, Bluetooth V4.0 is supported;
2.5 Network Module (Optional)
If the current radio supports network data transmission, users can transmit
their data via network, now radio can be used as CORS station, without the
need of RTK device, thus saving cost and simplifying outdoor operation. In
addition, network module supports 4G.

3 Functions and Operation
Instruction
3.1 Startup & Shutdown Button
The startup & shutdown button (power button) can be used to control radio
power-on and power-off, with specific functions as follows:
Short press the startup button for about 1 second to power on, the green
power indicator light illuminates in the case of successful power-on (under
the condition of normal power supply).
Under the condition of power-on, long press the startup button for 3
seconds to power off, the power indicator light goes out and the display is
closed.
The function of menu parameter confirmation
3.2 Left and Right Buttons
You can switch over various function menus through the left and right buttons.
3.3 Up and Down Buttons
In the current menu, you can select the corresponding menu item through the
up and down buttons.
3.4 Data Transmitting-receiving Indicator Light
While transmitting data, the red RX/TX indicator light illuminates; while
receiving data, the green RX/TX indicator light illuminates.
3.5 GPRS and Bluetooth Operating Condition
(Optional)
Include various operating conditions of the GPRS module and Bluetooth
module shown as below, if any module is abnormal, this condition can be
convenient for users to locating the problem:
If GPRS enters the condition of network data transmission successfully,
the red indicator light flickers once in three second;
If GPRS is detecting SIM card, the red indicator light flickers twice in three
second;
If GPRS is trying to access network, the red indicator light flickers four
times in three second;

If GPRS is re-connecting to the Corse station or server successfully, the
red indicator light flickers five times in three second;
Bluetooth led（green）is reserved.
3.6 Instruction of Radio Startup and Power Indicator
Light Conditions
Normal radio startup & shutdown has memory function, abnormal radio startup
& shutdown has memoryless function, with specific functions as follows:
In the case of abnormal shutdown for the last time, power on again after
outage, the radio powers on automatically;
In the case of normal shutdown for the last time, only by short pressing for
about 1 second can the radio power on after powering;
If the voltage is lower than the under-voltage threshold value (11.0V by
default, depending on the user‟s actual setting value), the red power
indicator light flickers twice in one second;
If the voltage is lower than the forbidden threshold value (10.2V by
default, depending on the user‟s actual setting value), the red power
indicator light flickers once in one second;
If the voltage is higher than the under-voltage threshold value (11.0V by
default, depending on the user‟s actual setting value), the green power
indicator light illuminates constantly;
When the voltage alarm appears, if it is under-voltage alarm, you need add
0.3V based on the under-voltage threshold value to resume to the normal
voltage operating condition (the green power indicator light illuminates
constantly);
Notes:
Abnormal shutdown means you do not power off by long pressing the
power button, for example, directly disconnecting power;
Normal shutdown refers to power-off by long pressing the power button;
3.7 Device Menu
It is categorized into two types of menus altogether: Basic radio parameter
menu and other features/functions menu.
3.7.1 Device Information
In the information column, the current channel number, current transmitting
frequency, current receiving frequency, current protocol, current transmitting

power, battery condition, device model, firmware version, hardware version
and serial number are displayed.
3.7.2 Transmitting/Receiving Channel and Frequency
In this menu column, you can set up the current transmitting/receiving
frequency, select required communication frequency through up and down
buttons, and press the OK key to select this frequency as the current
communication frequency point, the character of“*”will appear after selection.
3.7.3 Data Protocol
In this menu column, you can set up the current communication protocols such
as TRANSEOT, TRIMTALK and TRIMMK3. Select required communication
protocol through up and down buttons, and press the OK key to select this
protocol as the current communication protocol, the character of“*”will appear
after selection.

Note: After changing the protocol, you need reselect the RF baud rate
supported by the current protocol in the menu of “wireless link rate”;
3.7.4 RF Baud Rate
In this menu column, you can set up the current communication RF baud rate.
Different protocols support different types of RF baud rates. For example,
TRANSEOT supports 4800,9600, while TRIMMK3 supports 19200. Select
required RF baud rate through up and down buttons, and press the OK key to
select this RF baud rate as the current communication RF baud rate, the
character of“*”will appear after selection.
3.7.5 Transmitting/Receiving Mode
In this menu column, you can set up the current radio transmitting/receiving
mode. Now, four types of transmitting/receiving modes are supported:
transmitting-receiving, single transmitting, single receiving and relaying mode.
Select required transmitting/receiving mode through up and down buttons, and
press the OK key to select this transmitting/receiving mode as the current
communication transmitting/receiving mode, the character of“*”will appear
after selection.
3.7.6 Transmitting Power
In this menu column, you can set up the current wireless transmitting power
level. Now, three levels of power, high, medium and low, are supported, these
three levels of power values can be customized according to the demands of
users. Select required transmitting power through up and down buttons, and
press the OK key to select this transmitting power as the current
communication transmitting power, the character of“*”will appear after
selection.

3.7.7 Serial Port Baud Rate

triggering enabling. The former has memory function, if turning on the switch,
ON is displayed on the menu; if off, then OFF is displayed; self-adaptive
triggering enabling does not have memory function, the system remains in the
startup condition after power-on; only if the self-adaptive master switch has
been turned on can the adaptive function of serial port baud rate work
normally.
If the serial port baud rate is successfully self-adaptive, a message box pops
up indicating successful self-adaptive matching, meanwhile, self-adaptive
triggering enabling stops automatically. If the serial port baud rate is not
successfully self-adaptive, this function is always operating.
