USB/Charge Cable Setup
3. Connect the USB/Charge Cable cup to the bottom of the ET1. Align the ends of the cup with the alignment
marks on the ET1. The Battery Charge LED indicates the battery charging status. See Table 1-2 on page
1-6 for charging status indications. The 4620 mAh battery charges in approximately six hours.
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). Charging is intelligently controlled by the
ET1. To accomplish this, for small periods of time, the ET1 alternately enables and disables battery charging to
keep the battery at acceptable temperatures. The ET1 indicates when charging is disabled due to abnormal
temperatures via the Battery Charge LED. See Table 1-2 on page 1-6.
Communication
When the ET1 is connected to a host computer using the USB/Charge cable, the ET1 appears as a
Removable Disk on the host computer. Refer to the ET1 Enterprise Tablet Integrator Guide for more
