KIT-SEAL 8Q6290 - Caterpillar

Probable Causes
Another base radio is nearby and configured to the same network
The machine radio is configured as a base radio (and is not actually synchronized to anything)Problem Isolation
Ensure that power is removed from your base radio.
Cycle power to the rover radio and observe the lights on the bottom of the radio. If the orange (power) and green (data) LED indicator lights illuminate immediately upon power application, the radio is probably configured as a base radio and not as a rover radio. If the orange LED indicator light illuminates first followed by the green LED indicator light (typically 10 to 30 seconds to synchronize) the radio is probably configured as a rover.
Verify that the radio is configured as a rover. Cycle the power to the radio and note whether it synchronizes or not. If it does synchronize (to a base radio other than your base station radio), consider changing the network settings for all on-site radios.Intermittent Machine Radio Synchronization
Machine radio synchronization to the network is intermittent.Probable Causes
Near the outer limit of reception range of the base radio
External jamming or interference
Someone else is transmitting on the same network setting
Move the base closer to the work areaProblem Isolation
Move the machine closer to the base radio or add a repeater in order to add coverage. Use the following sources of information in order to verify the radio coverage area: AccuGrade system and AccuGrade Office.
"Jamming" can occur if the rover radio is in close proximity to a powerful transmitter such as another radio, microwave tower, or cellular tower.Machine Radio On Network But Not Receiving Corrections
Machine radio is synchronized to the network but the machine radio does not receive any corrections and the machine GPS remains in autonomous mode.Probable Causes
The base radio is powered and the network settings between the base radio and the machine radio are correct but any or all of the following conditions may exist:
The base GPS receiver is not plugged into the radio.
There is a port setting mismatch between the base radio and the base GPS receiver.
There is a configuration problem with the base
