If Incident Base does not respond to your check-in, which of the following is a suggested action?

When faced with a lack of response from Incident Base during a check-in, trying a different radio is a practical and effective action to take. This approach addresses potential communication issues that may arise from radio equipment malfunction, interference, or simply being on the wrong frequency. By switching to a different radio, you increase your chances of successfully re-establishing contact with Incident Base, which is essential for maintaining safety and coordination during search and rescue operations.

In emergency situations, maintaining communication is critical for providing updates on your status, receiving support, and ensuring that all team members are accounted for. Other options like leaving the field or starting a fire may not be viable—they could put you or your team at greater risk or may not effectively resolve the communication issue. Calling someone else on your phone might not work depending on the area’s cell signal coverage, especially if you are in a remote location. Therefore, trying a different radio represents the most immediate and reliable step to reconnect with Incident Base.
