Charging the ET1 Battery
To charge the battery:

Setup the cable as shown above.
2.
Connect the 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 status of the battery charging in the ET1. See Table 1-1 on page 1-4 for
charging status indications. The 4620 mAh battery fully 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 or accessory 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
