4G SIM Card Android GPS SpO2 Heart Rate Body Temperature Digital Smart Health Watch

Product Overview

1.78 inch Android 4G health watch with a one button SOS and braille alarm trigger

This watch shares the SL8541E Android 8.1 platform with the round 4G model but moves to a 1.78 inch 368x448 HD AMOLED screen in a 46.5 x 48 x 15mm case.

The difference that matters in care procurement is the one button SOS with braille alarm trigger, a tactile control a wearer can find without reading the screen.

Everything else in the care stack is present: 2G, 3G and 4G SIM calling, real time GPS location, safety guardance fence, remote listening monitor, dual 2 megapixel cameras and the full health sensing set including ECG and body temperature.

Comparison

How It Compares In Our Range

Against the round 4G model this watch is larger at 46.5 x 48 x 15mm, gains the 1.78 inch display and the one button braille SOS, and shares the same platform, cameras and battery. Choose the round model where discretion matters more than the emergency button.

Use Guide

Getting The Best Out Of It

1. Fit a nano SIM with voice and data before deployment.

2. Program the SOS call chain and test it end to end before the watch reaches the wearer.

3. Show the wearer the braille trigger by touch, with the screen off.

4. Charge daily; the specification quotes 2 to 3 days of use and up to 4 hours of calling.

5. Re-test the geofence on the deployment network after any SIM or carrier change.
