Maintenance and replacement of the recorder's standby battery 
When the recorder’s LED light blinks green,  check the recorder performance as follows.
1) Remove the standby battery.  If the LED light is off and the recorder stops working, the 
main power supply of the recorder fails.  Check the main power supply for connection and 
any other issues.  When the main power is available and the recorder starts working 
properly, Install the standby power supply.  If the LED light stops blinking, it means the 
standby battery is in good condition.  If the LED light continues to blink, it indicates the 
standby battery is low in power and it should be replaced.  The green LED light will stay on 
and the does not blink any more.
2) Remove standby power.  If the LED light continues blinking and the recorder works 
properly, it means the main power supply is in good condition and the standby battery is low 
and should be replaced.
    Replace recorder paper
Please follow the steps below for the replacement of recording paper: 
1. Find the pressing button (3#) at the top left corner in the front of the recorder panel; 
2. Press and hold the button (3#) for about 1 second till the recording pen begins to move toward the 
left of the paper; 
3. After the recording pen completely moves outside the recording paper, loosen the central bolt and 
remove the old recording paper. When replacing a new recording paper, carefully align the timeline 
on the paper to the time slot on the panel (there is a small indentation at the left of the panel); 
4. Retighten the central bolt, press and hold the button 3# for about 1 second to make the recording
 pen reset and start to record temperature; 
5. Examine whether the recording pen is easy to use on the paper; if it is not easy to use, adjust the 
crossbeam of the recording pen to make the nib contact with the recording paper. (Note: Do not
damage the nib and crossbeam. If it is difficult to be adjusted, use a screwdriver to dismount the
crossbeam. After bending the crossbeam with a little strength, install back the crossbeam and repeat 
the above operations); 
6. Ensure the accuracy of the recorder. Calibrate the preciseness of the recording pen after each
replacement of paper. Methods are set as follows: Press and hold the button (3#) till the recording
pen leaves the recording paper; then repress and hold the button (3#) till the pen get back to the
recording paper. At the moment, the pen will pause at the outermost temperature scale of the
recording paper (such a scale may not be marked with temperature value, but it is the outermost
scale). If the pen does not pause at the above location, you may utilize arrow key of 1# or 2# to
adjust the location of the pen within 5 seconds to make the nib aligning to the outermost scale.
Repeat step 6 if you do not complete the adjustment of the location of pen within 5 seconds.
