3. Setting up the receiver
3.1 Guidelines
Please follow these guidelines when setting up your receiver.
3.1.1 Environmental requirements
To keep the receiver with a reliable performance, it is better to use the receiver in
safe environmental conditions.
• Operating temperature: -40°C to +80°C
• Storage temperature: -45°C to +85°C
• Out of corrosive fluids and gases
3.1.2 Power supply
If you set M300Plus as a permanent site (reference station), an uninterruptible
power supply (UPS) is recommended to protect receivers from power surges and
power outage.
3.1.3 Mounting the antenna
Choosing the optimal location for the GNSS antenna is critical to the performance
quality of your M300Plus receiver. Poor or incorrect placement of the antenna may
