Using your Rio
Using the rechargeable backpack
Calibrating the battery ensures accurate battery level display. 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. 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 lamp 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 main-
tain the charge. In addition, you can use your Rio to play music while the backpack is charg-
ing.
Warnings:
Do not remove the rechargeable battery from the backpack. Batteries
may explode or leak if disposed of in fire, inserted backwards or disassembled.
