Don’t worry! It is normal. eOneBook has e-paper screens. One of the best features of e-paper is that the screen will retain the image displayed even without power.
Depending on the condition of the batteries used, they may run out before the message to urge you to replace the batteries appears. If your eOneBook doesn’t go to another page when you press any buttons, or if it displays “Just a moment" message repeatedly, please replace the batteries with brand new ones. If the problem continues even after replacing batteries, please contact us.
For your comfortable and economical use, employing rechargeable batteries is recommended. It allows you to read more longer than other disposable batteries do. You can also use them repeatedly by recharging.
During the warranty period: The cassette will be repaired or replaced at no charge(if the problem occurs under normal use following the User's Manual and the Safety Precautions.)
After the expiration of the warranty period: You can replace it with a brand-new one with 3,000 JPY handling charge. The cassette for replacement will be shipped after the broken cassette returned.
The manga cards are compatible only with eOneBook. Do not load it into other devices, as this could result in data corruption and damage to the device.
