  2. Clear panel AC and cell troubles before diagnosing wireless devices.
  3. Read zone trouble — tamper and low battery before "missing."
  4. Verify PowerG vs IQ Card 319/345 vs hardwire sensor matches panel hardware.
  5. For cell modules: ICCID, antenna, RSSI, and dealer platform match.
  6. Power-cycle panel only per dealer policy — document user codes first.
