2.1. Charging built-in lithium batteries

The DC 1500 has a lithium battery built in it. Before you start to use DC 1500 for the
very first time, please use the bundled USB cable to fully charge the built-in lithium
battery. It takes 2 hours to fully charge the lithium battery.

2.2. Installing batteries

Because the DC 1500 package doesn't provide any AAA alkaline battery, you have to
buy two additional AAA alkaline batteries for using DC 1500 if you don't want to use
the built-in lithium battery or when the built-in lithium battery runs out of electricity.
Please also note that DC 1500 are designed with a Protection Circuit, which makes
DC 1500 unable to power up if you insert the AAA alkaline batteries when the built-
in lithium battery are totally out of electricity. This protection circuit will cause DC
1500 unable to power up for a short period (5~10 minutes). During this period, the
DC 1500 use the AAA alkaline batteries as a sort of power supply to recharge the
built-in lithium battery in order to promote the operating efficiency of DC 1500.
Please don't be anxious about this temporary condition.
Follow the steps below to install battery.
