5.5.5 Reacquiring UTS lock
If the UTS loses lock on the target while you are working, the No UTS Data
message flashes on the guidance screen. To reacquire lock:
1. Stop the machine as soon as safely possible in clear view, and within 15m to
300m (50ft to 985ft), of the UTS.
Note – To acquire lock, the target must be within the search window defined
during UTS set up.
2. If Auto Search is enabled, wait for the UTS to reacquire lock on the target.
Otherwise, from any guidance screen, press UTS. The UTS dialog appears. Use
one or more of the following tools to reacquire lock:
To initiate a search of the entire search window, press Search.
To initiate a search of an area of the search window within 20m (66ft)
horizontally and 10m (33ft) vertically of your last known position, press
Quick Search.
5.5.6 Re-initializing orientation after moving the machine
After moving the machine you must re-initialize the orientation of the machine. For
more information, see 5.2.3 Initializing single-3D excavator orientation.
5.5.7 Clearing the UTS benched elevation
If you benched a UTS system, where the UTS instrument was set up with a known
elevation, the benched elevation of the instrument is used for position calculation
instead of the elevation specified during set up.
To clear the benched elevation and return to using the set up elevation:
1.
From any guidance screen, press and hold down \.
Note – Alternatively, to begin benching from the Setup Menu – Configuration
menu, select Bench.
2. Press Clear Bench.
Note – If the UTS instrument did not have an initial elevation, clearing the benching
data stops guidance.
