3. Plug the USB plug on the opposite end of the input/output cord into a USB port on a computer
or a USB power adapter (such as Tekkeon MP1600). The charging lamp will light as follows to
indicate the battery status:
Red On Batteries are charging
Green On Batteries are fully charged
Red Flashing Batteries are not usable, or are not rechargeable
Green Flashing No battery is installed, or batteries are installed incorrectly
If the lamp is flashing, ensure that the batteries are installed correctly, or replace the batteries with
good, rechargeable batteries.
4. When the charging lamp turns green (in approximately 3 hours for two batteries or 6 hours for four
batteries), the batteries are fully charged. Unplug the input/output cord from both TekCharge MP1550
and the computer or charger.
NOTE: The charging lamp will function only when
TekCharge is connected to external power via the mini
USB port. In this case, the capacity indicators on the
front of TekCharge MP1550 will be turned off.
It is strongly recommended to recharge the batteries only
when completely empty.
