air socket and measure again. Wrap the cuff correctly and keep arm steady 
during measurement. If the error keeps occurring, return the device to your 
local distributor or service center.

E1 / Air Circuit Abnormality:

 Make sure the L-Plug is securely connected 

to the air socket on the side of the unit and measure again. Another possible 
cause can be due to the short circuit of the microphone embedded in the 
cuff. If the errors still occur, return the device to your local distributor or 
service center for help.

E2 / Pressure Exceeding 300 mmHg:

 Switch the unit off and measure 

again. If the error keeps occurring, return the device to your local distributor 
or service center.

E3 / Data Error:

 Remove the batteries, wait for 60 seconds, and reload. If 

the error keeps occurring, return the device to your local distributor or service 
center.

Er / Exceeding Measurement Range:

 Measure again. If the error keeps 

occurring, return the device to your local distributor or service center.

No display when the START/STOP key is pressed:

 Re-insert the batteries 

in the correct positions.

Note:

  If the unit still does not work, return it to your dealer. Under no circum-
stance should you disassemble and repair the unit by yourself.

20.  Troubleshooting

1.   The unit contains high-precision assemblies. Therefore, avoid extreme temperatures,

protection against electrical shocks.

*Specifications are subject to change without notice.

Here are a few helpful tips to help you obtain more accurate readings:

•  Blood pressure changes with every heartbeat and is in constant fluctua

-

tion throughout the day.

•  Blood pressure recording can be affected by the position of the user, his 

or her physiological condition and other factors. For greatest accuracy, 

wait one hour after exercising, bathing, eating, drinking beverages with 

alcohol or caffeine, or smoking to measure blood pressure.

•  Before  measurement,  it’s  suggested  that  you  sit  quietly  for  at  least  5 

minutes as measurement taken during a relaxed state will have greater 

accuracy. You should not be physically tired or exhausted while taking 

a measurement.

•  Do not take measurements if you are under stress or tension.

•  During measurement, do not talk or move your arm or hand muscles.

•  Take your blood pressure at normal body temperature. If you are feeling 

cold or hot, wait a while before taking a measurement.

•  If the monitor is stored at very low temperature (near freezing), have it 

placed at a warm location for at least one hour before using it.

•  Wait 5 minutes before taking the next measurement.

1.  Press the User-Switching key to select memory zone 1 or memory 

zone 2.

15.  Measurement Procedures

3.  Center the tube over the middle of the arm. Press 

the hook and loop material together securely. Al-
low room for 2 fingers to fit between the cuff and 
your arm. Position the artery mark (Ø) over the 
main artery (on the inside of your arm) (Fig. 3,4).  

Note:

 Locate the main artery by pressing with 2 fingers approximately 2 cm 

above the bend of your elbow on the inside of your left arm. Identify where 
the pulse can be felt the strongest. This is your main artery.

4.  Plug in the cuff connecting tube into the unit (Fig. 5).
5.  Lay your arm on a table (palm upward) so the cuff is at the same height as 

your heart. Make sure the tube is not kinked (Fig. 6).

6.  This cuff is suitable for your use if the arrow falls within the solid color line 

as shown on the right (Fig. 7). If the arrow falls outside the solid color line, 
you will need a cuff with other circumferences. Contact your local dealer 
for additional size cuffs.

     After a memory zone is selected, press the START/STOP key to reset 

the monitor so it can start measurement in the chosen memory zone.

2.  Press the START/STOP key. All digits will light up, checking the display 

functions. The checking procedure will be completed in 2 seconds.

3.  After all symbols appear, the display will show a blinking “0”. The 

monitor is ready to measure and will automatically inflate the cuff 

slowly to start measurement.

4.  When the measurement is completed, the cuff will deflate entirely. Sys-

tolic pressure, diastolic pressure and pulse will be shown simultaneously 

on the LCD screen. The memory sequence number will blink and the 

Resting Detector symbol will appear on the display. The measurement 

is then automatically stored in the memory. 

     If ( ) appears on the display, this means the measurement was taken 

in a resting state (HSD Negative). Such measurement result can serve 

as a reference for the users and will be put into the Average of the last 

3 measurement calculation.

     If ( ) appears on the display, the Resting Detector orange light will flash 

about 6 times simultaneously. This means the measurement was taken 

not in a resting state (HSD Positive) therefore such measurement result 

shall be disregarded and will not be put into the Average of the last 3 

measurement calculation.

     If the user suffers from bradycardia or very slow heart rate, the device 

may not be able to detect the HSD properly during measurement. 

When this happens, the Resting Detector icon will not appear on the 

LCD screen.

This monitor will re-inflate automatically to approximately 220 mmHg if 

the system detects that your body needs more pressure to measure your 

blood pressure.

Note:

 1.  This monitor automatically switches off approximately 1 minute 

after last key operation.

          2.  To interrupt the measurement, simply press the START/STOP or 

Memory key; the cuff will deflate immediately.

          3.  During  the  measurement,  do  not  talk  or  move  your  arm  or 

hand muscles.

3.   Leaky batteries can damage the unit. Remove the batteries when the unit is not used for 

a long time.

4.   The unit should not be operated by children so to avoid hazardous situations.

5.   If the unit is stored near freezing, allow it to acclimate at room temperature before use.

6.   This unit is not field serviceable. You should not use any tool to open the device nor should 

you attempt to adjust anything inside the device. If you have any problems, please contact 

the store or the doctor from whom you purchased this unit or please contact Rossmax 

International Ltd.

7.   As a common issue for all blood pressure monitors using the oscillometric measurement 

function, the device may have difficulty in determining the proper blood pressure for 

users diagnosed with common arrhythmia (atrial or ventricular premature beats or atrial 

fibrillation), diabetes, poor circulation of blood, kidney problems, or for users suffered from 

stroke, or for unconscious users.

8.   To stop operation at any time, press the START/STOP key, and the air in the cuff will be 

rapidly exhausted.

9.   Once the inflation reaches 300 mmHg, the unit will start deflating rapidly for safety reasons.

10.  Please note that this is a home healthcare product only and it is not intended to serve as 

a substitute for the advice of a physician or medical professional.

11.  Do not use this device for diagnosis or treatment of any health problem or disease. 

Measurement results are for reference only. Consult a healthcare professional for 

interpretation of pressure measurements. Contact your physician if you have or suspect 

any medical problem. Do not change your medications without the advice of your 

physician or healthcare professional.

12.  Electromagnetic interference: The device contains sensitive electronic components. Avoid 

strong electrical or electromagnetic fields in the direct vicinity of the device (e.g. mobile 

telephones, microwave ovens). These may lead to temporary impairment of measurement 

accuracy.

13.  Dispose of device, batteries, components and accessories according to local regulations.

14.  This monitor may not meet its performance specification if stored or used outside 

temperature and humidity ranges specified in Specifications.

15. If a constant arrhythmic pattern is present (e.g. atrial fibrillation), this will mean that HSD 

might become positive.
