Chcek List Before Use

1. Visual inspection

(1) Whether the RTK antenna is damaged

(2) Check whether the casing is damaged, so as to prevent the circuit board from being damaged due to

the entry of external water

(3) Whether the sealing plug is tightly closed to prevent the circuit board from being damaged due to the

entry of external water

2. Power-on check

(1) When the device is in the off state, after pressing the Power button (t>1.8s), the device will enter the

on state, and the 9 LEDs on the interface will light up at the same time (mainly to check whether all the

LEDs work normally), after 2s, the device will enter the power-on state. system initialization;

(2) System initialization:

1 PWR LED is always on;

2 The Battery LED first displays the battery level (3s) and then turns off

3 Function module LEDs (communication, WiFi/Bluetooth, DGPS, fault) turn on and off in sequence

4 After the startup is completed, the PWR LED continues to keep on

(3) Note

1 It can be turned off at any time during startup.

2 At any time, pressing the Power button for more than 15s will trigger the device (hardware) to

force shutdown.

3. Shutdown check

(1) When the device is on or working: Press the Power button (2.5s<t<15s), the 9 LEDs on the interface will

turn off at the same time, and the device will enter the standby state first. If there is no instruction for

more than 10s, the device will enter the shutdown state ;

(2) If the user tries to press the Power button to turn on the device during standby (t>1.8s), the device will

resume the power-on state; if there is no instruction after 10s, the device will enter the power-off

state;

4. Battery check

(1) Short press the switch button (0.1s<t<0.5s), observe the battery light to display the remaining power;

(2) After pressing the Power button (0.1s<t<0.5s), the Battery LED will display the battery level (3s), and

after the display is over (>3s), the LED will turn off; if you press the Power button (t<0.1s or t>0.5 s), the

power is not displayed (the command is regarded as invalid);

5. Battery display

(1) In the case of non-charging,:after pressing the Power button (0.1s<t<0.5s), the user can check the

power according to the displayed power grid information.

For example: when 50%<SoC<75%, Batt1+Batt2+Batt3 is always on for 3s, and goes out after 3s;

(2) When charging: the corresponding battery bar flashes, and the fully charged battery bar is always on.

For example: when charging 50%<SoC<75%.Batt1+Batt2 are always on, and Batt3 is blinking. When the

battery is fully charged, the 4 battery bars are always on. The flashing frequency of the battery bar

indicates fast charging or slow charging.
