Step 3. Is The Base System Transmitting Data; Step 4. Is The Base Radio Antenna Connected To The Base Radio; Step 5. Is The Rover Radio Set To The Same Frequency As The Base - ashtech Z-Xtreme System Manual

Antenna not connected
Connect the radio antenna to the radio. Ensure that the connection to the
radio and the antenna are snug and not cross-threaded.
Antenna is connected
Ensure the connections to the radio and the antenna are snug and not cross-
threaded.
Go to step 3 if the problem is not yet resolved.

Step 3. Is the base system transmitting data?

To determine if the base system is transmitting data, observe the transmit LED on the
front panel of the radio. The transmit LED will blink red each time a packet of data is
transmitted. The GPS receiver by default is set to send data to the radio once every
second. The radio will transmit this data immediately after receiving it. Therefore, the
transmit LED should blink once every second indicating data transmission.

Step 4. Is the base radio antenna connected to the base radio?

The base system will transmit data without a base radio antenna but the
range will be severely limited.
Antenna not connected
Connect the radio antenna to the radio. Ensure that the connections to the
radio and the antenna are snug and not cross-threaded.
Antenna connected
Ensure that the connections to the radio and the antenna are snug and not
cross-threaded.
Go to step 5 if the problem is not yet resolved.

Step 5. Is the rover radio set to the same frequency as the base?

The rover radio must be set to the same frequency as the base radio in order for the
rover to receive transmissions from the base. Use the field application software run-
ning on the handheld computer to determine on which frequency the base and rover
