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 green indicator light illuminates constantly;
If GPRS does not detect SIM card, the green indicator light flickers once in
one second;
If GPRS does not access network successfully, the green indicator light
flickers twice in one second;
If GPRS does not connect to the Corse station or server successfully, the
green indicator light flickers three times in one second;
If Bluetooth matches successfully, the red BT illuminates and the Bluetooth
icon appears in the condition, if the offline icon disappears, the BT
indicator light goes out.
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 (11.8V 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 (11.5V 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 (11.8V 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

corresponding server type and set up related information such as IP
address, port number and mounting point;
Note:
If the radio does not support GPRS, the settings of related parameters in the network setting
column are invalid; if the operating voltage of the radio is lower than the low-voltage alarm
threshold value, the red power indicator light flickers twice in one second; if the operating
voltage of the radio is lower than wireless data transmission voltage, the radio stops
transmitting user data; when setting up, the low-voltage alarm threshold value must be larger
than wireless data transmission voltage.
3.9 Firmware Upgrade
If the radio runs under the normal operating mode (data transmission mode),
online upgrade for serial port is supported, with the firmware upgrade
procedures as follows:
1. Firstly, use the designated power cable to connect to the big radio, with the
power supply of 9-16V; use the serial port cable (USB to RS232 serial port
cable) to connect to the power cable terminal RS232 male connector,
power on for powering the radio, if the radio has not been powered on,
long press the power button for 3 seconds before power-on, until the
system enters into the normal operating mode
Note:
“RS232”is 232 level, not TTL level. Use USB to serial port cable or RS232 serial port
cable and PC to establish connection.
2. Find the upgrade tool and open the software.

3. Select right serial port number and baud rate, open the serial port and
select internally installed radio, as shown in Figure 5.
Figure 5 Internally Installed Radio Firmware Upgrade Software Connection

4. Select the file requiring upgrade (e.g.***.**.**F.dwn)

5. Click the “Begin to Update” button (when you click the “Begin to Update”
button, one prompt dialog box pops up indicating whether a parameter is
correct, now users are required to click OK; after that, the system enters
into the upgrade condition immediately)
6. After upgrade, the prompt pops up indicating successful upgrade, click OK
for completion of upgrade this time;
7. The system powers off before powering on again, if the radio has not been
powered on, short press the power button for 1 second before power-on;

FCC Statement
FCC Caution
§ 15.19 Labeling requirements.
This device complies with part 15 of the FCC Rules. 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.
§ 15.105 Information to the user.
Note: 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.
§ 15.21 Information to user.
Any Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 2m between the radiator & your body.
