NEC N938 user manual, which introduces the use of the mobile phone, precautions and safety rules and other content.
This manual covers emergency service instructions, safety precautions for various environments (airplane, hospital, road, fuel stations), and proper handling of the device, including battery replacement and use of accessories. It also explains the phone's hardware features such as the built‑in antenna, screen operation, and key functions.
Additional sections describe warranty considerations when using non‑NEC equipment, regulatory compliance for RF emissions, and a repair guide with contact information for authorized service centers. A FAQ at the end addresses common usage problems. This manual is written in Chinese.
Press 112 (or 999 in the UK) and tell the operator the required service and your location.
The built‑in battery must be replaced only by a professional repair engineer.
If the battery is depleted, replace it with a new one or charge the phone.
