Cautions for use of timing program player

Due to the rapid development of U-disc and

various memories on the market and the

complex and disordered condition of the U-disc

on the market, this product is possibly not

compatible with all the U-discs in any brand,

type and specification on the market. However,

this equipment is based on ARM system

platform, so the compatibility with U-disc is

relatively stable. This equipment is compatible

with most of the U-discs in the standard brands.

The equipment only supports the song file in

the format of MP3 with the maximum code rate

of 320KBPS; it is unable to play the audio files

in the other formats. If it is unable to play a

song, please check whether such song is

satisfactory to the above requirements.

When using the timing player, attention shall

also be paid to the following:

Prior to the editing of the timing point, the user

shall get the song program to be used for timing

in advance. In the SD card of this equipment,

some common programs have been preset, and

the user may delete or add the songs as required.

It is not allowed to change the timing programs

in the SD card at random only if such programs

are defined; otherwise, it is possibly required to

reedit all the timing points.

The programs in the SD card shall be played on

a timing basis. In order to guarantee the easy

and rapid editing of the timing point, it is

recommended to store the useful programs only,

and to delete the useless program as much as

possible. The programs not to be played on a

timing basis shall be put into the external

U-disc. The timing programs shall be classified

by inventories and placed properly. It is

recommended that there shall be no more than

10 inventories in total, and no more than 50

songs under each inventory in total so as not to

waste time and energy to edit the timing point

and seek for the songs.

For the purpose of easy display, only the

primary inventory is supported in U-disc and

SD card. Please do not create the secondary

subdirectory under the primary directory.

Limitation to length of song name: The song

name in Chinese shall consist of no more than

15 Chinese characters; the song name in

English shall consist of no more than 30

English letters; otherwise, it is possible to make

mistake in display or unable to display.

When formatting the SD card, it is necessary to

format into the file format of FAT32.

It is recommended to turn off the power of the

mainframe first when plugging in or pulling out

the U-disc and SD card; otherwise, it is possible

to burn out the U-disc or SD card in the course

of reading and writing.

When operating, in particular when editing the

timing point, please operate with the touch pen

as far as possible. The position of the touch

point operated by the touch pen is relatively

accurate and reliable.

When editing the timing point, the playing of

the current program will be stopped, which

shall be deemed as a normal phenomenon.

When editing the timing point, the execution of

the timing point will be suspended, which shall

be deemed as a normal phenomenon. After

completing the editing of the timing point, the

execution of the timing point will be restored

When editing the timing point, the same time

point is allowed; however, the overlapping of

the dates selected for the same timing points is

not allowed; otherwise, it is unable to exit the

editing interface.

By editing the timing program of the timing

point, only the programs in the built-in SD card

can be controlled on a timing basis but not the

programs in the U-disc.

If the program in the timing point is null, it

means that the playing of the current program is
