Product Introduction
This MP3 Timing player based on ARM32 bits microprocessor system platform and integrating
the playing of program from U-disc and SD card and the timing control of the playing of the program
from SD card. In the equipment, 4.3”liquid crystal touch screen is used for display with the captions in
Chinese and English for option. All the functions and the condition of the equipment are absolutely
clear. It is easy to operate by touch. Any operation of the equipment is visualized and clear, and the
human computer interaction manifests the humanization and intelligence.
This equipment supports most of the marketable USB memory equipment and SD cards. Therefore,
it is possible to implement the timing playing control of the program from SD card, edit the information
on the timing point on the computer, and copy through the SD card to this equipment for
implementation, or copy the timing point on this equipment through SD card to the computer for
storage and backup; it is allowed to turn on the power of the equipment within 1-60 seconds (time
settable) before the timing point is coming.
The earphone monitoring circuit is built in the equipment. By access of the earphone on the front panel
of the equipment, it is possible to monitor the playing state of the equipment. In the equipment, there is
a route of AC 220V power output socket which is used to provide the working power for the other
equipment. Furthermore, the on-off state of such power output socket is subject to the timing control by
the timing point or the manual control so as to facilitate the user. In this equipment, there is a route of
short-circuit signal output interface, which is connected to the equipment needing the short circuit
trigger signal so as to play a role in emergency linkage.

On the screen calibration interface, click the
center of the small cross icon (In the black
circle in the diagram) with the pen point (Note:
Be sure to click the center).
Calibrate as above-mentioned at the four
corners and the center of the screen
respectively; if the four corners and the center
of the screen are not calibrated accurately, it is
impossible to move the selection icon to the

Important prompt:
When calibrating the screen, it is required
to align with the “cross” cursor carefully
and then click; be sure not to click the
screen at random; otherwise, it is possible
to make the mistake in calibration,
resulting in the occurrence of the
inoperability. Furthermore, when
calibrating the screen, it is required to
operate with the touch pen so as to reduce
the probability of the operation mistake.

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

stopped without the audio output. Similarly, it
is allowed to stop the playing of MP3 at certain
time by such method.
The daily program is only used as the special
supplementation to the weekly program and
executed in parallel to the weekly program.
However, if the timing point in the daily
program is the same as the time of the timing
point in the weekly program, the priority shall
be given to the execution of the timing point in
the daily program.
The equipment is able to export the timing
point of the mainframe to the SD card; after the
exporting, please keep a backup of the timing
point in such SD card into the computer.
After the download or exporting of the timing
point or the exporting of the song, it is required
to restart up.
If the equipment fails to execute the timing
point, please check whether the equipment is in
the manual state or whether the timing program
to be executed is not selected.
