This manual introduces the TC-890GM high‑end cluster walkie‑talkie, which complies with GA176‑1998 police standards and supports cluster operation, 6‑channel phone calls, GPS positioning, and an LCD colour display. It also details the supported signalling standards (CPSX, MPT1347) and the device’s ability to work with MPT1327‑based systems.
The guide covers pre‑use preparation (battery charging, SIM card installation, accessory mounting), basic operation (power on/off, mode switching, volume control, call handling), module‑specific functions (cluster mode, conventional mode, police information module, mobile phone module), troubleshooting, maintenance, warranty terms, optional accessories, and a glossary of terminology. This manual is written in Chinese.
