## 7. Full Description

### A communication tool you can rely on, every single day

If you've ever watched a dropped call, a dead battery or a fragile phone slow down a shift, you know exactly why the UNIWA F400 exists. It's built around one idea: communication that simply works — whenever and wherever you need it. Think of it as the dependability of a landline, but portable, powerful and built for the real world.

### Instant contact, at the press of a button

Forget dialing, waiting for pickup and fumbling with apps. The F400's dedicated Push-to-Talk (PTT) button gives you walkie-talkie-style communication over 4G cellular networks — press and talk, release and listen. Whether your team is spread across a warehouse, a construction site, a delivery route or your own property, everyone stays in the loop in seconds. It works with popular PoC apps like Zello and PoCstar, and it still makes crystal-clear standard phone calls whenever you need them.

### Made to take a beating

The F400 is engineered for demanding environments. Its IP65-rated housing keeps out dust and protects against water jets, while the reinforced PC + fiberglass two-color body and tough buttons are designed to survive the drops, bumps and rough handling of daily field work. Rain, dust, mud — the F400 keeps right on talking.

### The latest Android, ready for work

Running Android 15 with a MediaTek Helio G81 octa-core processor, 4GB of RAM and 64GB of storage (expandable to 256GB with a microSD card), the F400 handles dispatch apps, forms, messaging, maps and workflow software with ease. A bright 4.0-inch capacitive touchscreen keeps everything readable — even in bright daylight.

### Power that lasts the whole shift

The removable 4350mAh battery is built for long days, and 15W fast charging gets you back in action quickly. When you're on back-to-back shifts, carry a spare battery and swap it on the spot — no downtime, no charging cables hunting for an outlet.

### Safety at your fingertips

A dedicated SOS button lets you call for help instantly in an emergency, and the programmable custom key gives you one-touch shortcuts for the apps and actions you use most. Front 13MP + 5MP cameras with an infrared night-vision camera let you capture clear evidence and images even in the dark, so you can document incidents, inventory and job sites around the clock.

### Connected everywhere you work

Multi-GNSS positioning (GPS, GLONASS, Galileo, BDS) keeps you and your team on the map, while NFC supports secure access, asset tracking and data transfer. Dual-SIM support (2× Nano SIM) lets you separate work and personal lines, and dual-band Wi-Fi plus Bluetooth 5.0 handle the rest of your connectivity needs.
