Using your Rio
Using the rechargeable backpack
The first time you charge the battery backpack, it is important to calibrate it and give it a full
charge overnight or until the calibration timer expires. Calibrating the battery ensures
accurate battery level display. You do not need to charge the battery before you calibrate it.
Note: You do not have to calibrate the battery each time you charge it—only the first time.
See the section on Battery Calibration for instructions and more information.
For subsequent chargings you can charge the backpack until the charge indicator goes off for
a quick charge—after about 1.5 hours—or leave the AC adapter attached for about 2.5 hours
for a full charge. Full charge allows you to play music for about 10 hours.
You can leave the backpack plugged into the AC adapter after charging is complete to
maintain the charge. In addition, you can use your Rio to play music while the backpack
is charging.
Warning:
Do not remove the rechargeable battery from the backpack. Batteries may
explode or leak if disposed of in fire, inserted backwards or disassembled.
