charge. Fully charge the battery will take 4 hours typically. The battery indicator is red
when charging, will turn green when fully charged.
3.3 Insert radio antenna
The antenna is required in radio working mode.
3.4 Measure antenna height
In order to get correct elevation value, we need to know the correct phase center
height of the receiver. However, it is almost not possible to measure the phase center
directly. Normally, the software will read the receiver antenna offset parameters.
Once user input the measurement height, software will calculate the phase center
height automatically. Typically, there are two ways to measure the height:
A: Slant height (to measurement line)
• Centering and leveling the tripod on known point, then measure slant height from
the ground point to the arrow at the side of the receiver.
B: Pole height (straight height to device bottom)
• Read the straight pole height
A: Slant height Measurement Line B: Pole height
