2.6 Firmware Upgrade
You can upgrade the firmware of the receiver, motherboard and module by using a USB cable, the web
management system or online remotely.
2.6.1 Upgrade by USB Cable
Steps to using a USB cable in order to upgrade the firmware:
1. Turn on the receiver and connect it to a computer with the cable attached. This will show the updated drive
in the receiver.
2. Copy the firmware (which can be downloaded from our official website or the technical team) to the receivers
update drive. Disconnect the computer and restart the receiver, which automatically recognizes the firmware
and starts the firmware upgrade process.
3. There will be different prompt voices for the success or failure of the upgrade. If it fails, please contact our
technical team.

Notice: Don’t move the tripod or change the collecting set while the receiver is collecting data.
1. Make sure the pole height is consistent with the set pole height before the tilt survey.
2. When turning on the Tilt Survey switch, you will need to complete the initialization operation
before normal use.
3. To meet most users’ operational needs, the maximum measurement angle of the tilt survey is
70°.
4. To ensure measurement accuracy, do not turn the device quickly during the measurement
process.
5. Data quality is not as good in an occluded environment. If accuracy requirements are high,
please try to use this function in an open environment.
6. When you enter the tilt survey for the first time every 7 days, you need to complete the static
calibration according to the prompts you receive. Let the device stand for about 10 seconds to
complete this.
