Display 

The STARwatch band has an illuminated display that provides status indicators to 
both device administrators and subjects. When the band is docked the display has a 
landscape orientation and off the dock it has a portrait orientation.  

Touch 

Users can toggle display modes of the STARwatch band using the touch interface on 
the front face. A long press on the face will awaken the screen. Subsequent short 
presses will toggle the display page. 

Battery 

Power is provided by an internally-sealed rechargeable Lithium-Ion battery. The 
battery charges when placed on the dock. Recharge time will vary based on the level 
of battery, but a full charge from empty to full will complete within 1.5h. A battery 
full indicator is shown on the band display, and within the software when a full 
charge has been achieved. 

Dock 

 

Charge-only use 

The dock can be used just to charge bands, by connecting the USB cable to any USB 
port that can provide power. The USB port may be a USB wall-adapter, a computer 
(with or without the STAR software), or on a USB hub.  

Charge and data connectivity use 

When the dock’s USB cable is connected to a computer that is running the STAR 
software, it provides both battery charging and data connectivity. When a band is 
connected to the dock its battery will charge automatically if it is not full, and the 
band will appear in the STAR software. 

 

Range 

±4g, ±8g, ±16g 

Maximum acceleration range. Higher ranges 
allows faster movements to be detected. 
Lower ranges provider greater sensitivity for 
slower movements.
