Electronic boards are electrostatically sensitive. Failure to observe proper handling precautions for static-sensitive components can result in damage to the electronic components. Do not remove the electronic boards from the 3300 Radar Transmitter.

To ensure long life for your radar transmitter, and to comply with hazardous location installation requirements, tighten covers on both sides of the electronics housing.

The transmitter monitors its own operation. This automatic diagnostic routine is a timed series of checks repeated continuously. If the diagnostic routine detects a failure in the transmitter, the 4–20 mA output is driven upscale (high) or downscale (low) depending on the position of the Alarm switch.

Security write protection prevents unauthorized access to configuration data through the Rosemount Configuration Tool (RCT) software, a HART 275 Communicator or Asset Management Solutions (AMS) software.
