   2. If no, relocate the antenna to the highest point in the vault and Step 3.
5. Is the antenna SMA connector corroded?
   • If yes, move to Step 4.
   • If no, continue to Step 3.

Step 3: Swipe a magnet along the FM200 serial number barcode

1. Listen for a series of error beeps. Wait approximately 5 minutes
   • Did you hear a series of error beeps?
     • If yes, see the chart below for the next steps
     • If no, continue to step 3-B

Step 4: Verify Status in the FM200 Activator 

1. Verify communication Signal Test in the FM200 Activator
   • Did the device communicate?
     • If yes, continue to Step 3-D
     • If no, continue to Step 4
2. Verify battery level in the FM200 Activator.

     • If yes, complete the forms and depart the site.
     • If no, continue to step 4.

Step 6: Replace the FM200 device.

DO NOT replace the device BEFORE completing steps 1-5 and failed to establish good service.

1. Install a new FM200 flow monitor.
2. Complete the Device Replacement Form
3. Return the old FM200 flow monitor via RMA. Do not discard the device.

Error Code Beeps

Confirm the error code by swiping the magnet once again. Carefully listen for the total number of beeps emitted by the device. The beeps will occur in rapid succession. Additionally, the beeps emitted from the device will have a different tone from the beeps heard during the installation process. As a reminder, it may take up to 5 minutes for the device to generate and emit the error. Please be patient.
