Motorola Q 9c ユーザーズマニュアル

Your device supports the use of an optional miniSD (Secure 
Digital) memory card (available separately) to expand the 
device's available memory space. You can use cards with up to 
32GB in memory, depending on market availability.

Using memory cards allows you to easily store images, videos, 
music, and voice data in your device.

If your battery has been completely drained, it cannot be 
charged via the USB cable plugged into the computer (this 
connection will only maintain current battery life). Use a wall 
charger or car charger to recharge the battery. Some 
computer USB ports provide a higher current than others, and 
will provide more rapid charging.

The mini-USB port does not support headphones. You must 
use 2.5 mm headphones or a Bluetooth mono or stereo 
headset.

Don’t bend or scratch your memory card. Keep it away from 
static electricity, water, and dirt.

The miniSD card and its adapter can be easily damaged by 
improper operation. Please be careful when inserting, 
removing, or handling them.

At the time of this printing, 8GB is the largest commercially 
available miniSD card.
