Trouble Shooting - Casio V-REGI series Programming And Reference Manual

Avoid using Return key of Android.
To finish the sales management system, finish it by the sales management's ending
operation on the top menu. Do not finish the sales management system or return to
Android system using Return or Home keys of Android system.
Update the sales data periodically.
Before Z reporting, sales data of sales management system is stored in the main
unit and in an SD card (Internal Storage) after Z reporting as a database file. As a
characteristic of Android system and SD card (Internal Storage) file system, there is
a risk of inability to read stored files. Please back up important data to SD card or
USB memory periodically.
Recommendation of shutting Android system down
As a characteristic, Android system reduces the resource if it is not shut down for
long time causing troubles such as reducing operation speed. To avoid this, we
recommend to shut the Android system down at the end of business day.
Sales management system is affected by other installed applications
Sales management system is operated as one of Android system applications.
Although it is possible for Android system to install other application than sales
management system, abnormal termination may occur at finalizations or Z reporting.
It is because the application consumes a large amount of Android resources and the
sales management system cannot access to the file system.
Hardreset may damage the file system
When Android system or an application does not respond, you might hard reset the
system. However, a hardreset may cause a damage of Android system or a file
system of an SD card. Please do not hard reset the system easily.
Press Hold when an ANR dialog is shown.
When an ANR (Android Not Responding) dialog such as "xxx is not responding." Is
shown, press Hold key. If the same message is shown repeatedly, press Forced
termination key.
