initiates the first network synchronization, and performs auto-registration to Command Center. To be
able to sync to a network the GPR must have the same CRC number as that of the Network. During
auto-registration the GPR requests for operation and meter specific configurations from Command
Center. When the new configuration data is obtained, the GPR reconfigures itself, reboots, and then
changes operation to Normal Mode.
Once the GPR is properly mounted and connected to the pulser, it is ready for operation to start. To
start the GPR in Install Mode follow the procedure below.
1. The sensor cable should be installed before the battery connection to avoid false counts at
startup.
2. Apply dielectric grease compound to the battery connector. See Appendix A GPR Waterproofing
for more information.
3. Apply power to the module by making the battery connection.
4. Remove the foam between the battery and the PCB and discard it.
5. Observe the LED on the module for proper start up. Shortly after power is applied the LED will
flash once every 5 seconds for 60 seconds to indicate to the installer that the module is in
Installation Mode, and is operating normally. If an error is encountered, the LED will flash twice
per second to indicate there is an error and continue flashing until power is disconnected.
6. If the module started operation correctly, mount the cover as shown in the next 3 steps.
7. Arrange the GPR Pulse Input and Battery Interface cables as shown in Figure 7 - 15. The cables
must not interfere with or block the GPR antenna. Pull the wires over the connector as shown.

8. Install the GPR cover using the four security Torx screws included with the GPR. The cover
must be installed with the gasket tab inserted into the strain relief slot located at the bottom left
corner of the GPR enclosure as shown in the following photos.
