Exit the Setting Mode without Save
If you want to exit the setting mode without saving any changes, you must have the
scanner read the "Exit without Save" barcode.
Just like reading the "Enter Setup" barcode, the scanner will respond with three beeps
(tone ascending from low to high) after reading the barcode.

"Restore Factory Defaults" is a special barcode. The CT20 Barcode Scanner will respond
with a short beep (high tone) after reading this barcode. At this time, the scanner system
could restore factory defaults, and no need to read "Exit with Save" barcode again. The
Scanner defaults enable HID, PIN defaults 10010.
Note: Most of setting mode have restore factory defaults selection. The factory default
value for each setting is indicated by an asterisk "*".
You could use this barcode at the following status:
1、The scanner can not work. For example, it can not read barcodes.
2、You forget the settings you did to the scanner before, and you don't want to be affected
by the settings when you use the scanner.
3、After using a function which is not be used usually in the scanner.

1.1 Battery
The scanner is powered by two AA batteries or AAA alkaline batteries. The batteries can
support the scanner work continuous for 60 hours, or read 56000 barcodes (read an EAN-13
barcode per 5s).
1.1.1 Mounting the battery (charging)
1) Hold the scanner face down in one hand.
2）Press the back case and push like picture.
3) put in the batteries.
4）close the back case.
1.1.2 How to operate CT20 Barcode Scanner
Turn on the scanner
Press the Power key for about 2 seconds. The scanner will respond with a long beep (high
tone), and its LED indicator is flashing.
Turn off the scanner
Press the Power key for about 3 seconds. The scanner will respond with two short beeps
(high tone) and the LED indicator is turn off.

15
1.1.3 Auto Power Off
In order to conserve battery power, the user can specify the time interval for the scanner
to automatically turn off. By default, it is set to 10 minutes.
For example: Set 20 minutes for the scanner to automatically turn off.
1. Read the "Enter Setup" barcode;
2. Read the "Enter Auto Power Off" barcode;
3. Read the "20min" barcode;
4. Read the "Exit with Save" barcode.
Note: If you want to keep the scanner power on all the time, read "Exit Auto Power Off" in
stead of step 3 and 4.

1.2 Transmit Buffer
During the Bluetooth connection, the CT20 Scanner uses a 2KB memory as a data buffer,
and sends the collected data to the host computer one by one via the Bluetooth. Upon
reading a barcode successfully, the scanner responds with one short beep and its LED
indicator becomes green and goes off quickly. However, the host computer may not
receive the data immediately if getting out of range. With the 2KB transmit buffer, the
scanner can ignore the transmission status and keep on reading barcodes until the buffer
is full. When the buffer is full, the scanner will respond with a long beep (low tone), this
reminds the user that the space of buffer is not enough and can not read barcode any
more. @ Once the Buffer is full, the user should return to the range of BT connection
quickly, the data in the buffer can be sent back to the host computer and release the
space of buffer.
Note: The 2KB transmit buffer on the scanner can hold as many as 110 barcodes bases
on EAN13. You can choose to clear the data in the buffer every time when you
turn on the scanner.
Note: You can clear the data in the buffer via enable barcode, you can also clear the data
in the buffer via press the Power key long time.
After the Bluetooth connect successfully, the barcodes in the buffer will upload to
appointed position automatically. You also can setup upload the barcodes in the buffer or
not via read the following barcodes. By default, it is enabled.
If you don’t want to upload the barcodes automatically, you can setup as disabled, when
the Bluetooth connect, the barcodes won’t upload. You can double click Power key to start
upload the barcodes.

1.2.1 Inventory Mode
If you want to keep the barcodes in the buffer of CT20 for multiple uploading, you can
choose inventory mode. In inventory mode, CT20 will count the number of the barcodes
automatically, and control the time, position etc. for uploading. Also, you can clear the
barcodes in the buffer after uploading. Following is the setup method:
1) Read ‘Enter Inventory Mode’ barcode to enter into the inventory mode
Enter Inventory Mode
2) If you want to recover to normal mode, read the ‘Enter Normal Mode’ barcode
Enter Normal Mode
3) Read the ‘Clear the barcodes in the buffer’ barcode to clear the barcodes (only
suitable for inventory mode)
