1. Describe one setup

This is a blank observational record, not a certification form. No test has been performed or recorded here. Use equipment you already have; a different setup needs a separate record. Read the companion guide before starting.

Date and time
Bag make / model
Bag condition
Closure instructions used / manufacturer document
Target device model
Operating system / software version
Existing second device / accessory and software, if used
Location, distances, and orientation

Circle one intended connection: cellular / Wi-Fi / Bluetooth. Treat each as a separate check.

How the actual connection path was established
Band / channel if available (otherwise “unknown”)
Relevant settings, including alternate connection paths
Observable event or fresh data used
How observation is possible while the bag remains closed
Chosen interval
Planned repetitions
Existing recording / log filename, if any

Keep the intended radio on, use the manufacturer’s closure instructions, and keep charging cables out of the opening. A quiet phone is not proof of isolation. The guide and its sources explain the limits.

2. Baseline → closed interval → recovery

Use the same devices, settings, placement, and location. Record changes or interruptions. Three blank runs are provided for convenience; this is not a standard or a statistical guarantee.

Run 1

Outside-bag baseline
Closed start / end time
Exactly what was observed while closed
Reopened recovery
Result / limitation

Run 2

Outside-bag baseline
Closed start / end time
Exactly what was observed while closed
Reopened recovery
Result / limitation

Run 3

Outside-bag baseline
Closed start / end time
Exactly what was observed while closed
Reopened recovery
Result / limitation

Result labels: communication observed / communication not observed during this interval / inconclusive / not tested.

For a call, caller ringback is not the target-phone observation. For data, record fresh traffic rather than a cached display. For Bluetooth audio, note continuation and interruption times; the first instant may reflect a buffer.

If baseline or recovery fails, the path is unclear, or opening the bag is required to observe the event, explain the limitation. Do not attribute the outcome solely to the bag, convert these observations to decibels, or expand them to untested bands, devices, conditions, or security claims.
