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

3.1.2 Power supply
The M300Pro has a built-in internal Lithium battery, which can work for up to 16
hours. If you set M300Pro as a permanent site (reference station), a uninterruptible
power supply (UPS) is recommended to protect receivers from power surges and
power outage.

quality of your M300Pro receiver. Poor or incorrect placement of the antenna may
impact the accuracy and reliability of observation, resulting a degraded performance
of normal operation.
