| Feature | Manual Description | Real-World Implication | |--------|-------------------|------------------------| | | 0.9” red LED, 4-level dimmer | Legible at night, but red LED can bleed in pitch darkness. Dimmer is essential. | | Bluetooth | v5.0, 33ft range, auto-reconnect | Good for streaming. v5.0 means decent battery life if used as portable speaker (though mains-powered). | | FM Radio | Auto-scan, 10 presets | Basic. No mention of RDS (radio text) – so no song titles. | | Dual Alarms | Separate weekday/weekend settings | Critical for shift workers or couples. Manual shows separate alarms for Mon-Fri vs Sat-Sun. | | USB Charging | 5V/1A output | Slow by modern standards (5W). OK for overnight charging of an old phone, but not a fast-charging iPad or modern Android. | | Backup Battery | CR2032 (keeps time during power loss) | Does NOT power the alarm to wake you – only preserves clock settings. Major distinction. |
