Precautionary measures GB • The blood pressure measurements conducted with this unit are equivalent to measurements obtained by a trained observer in accordance with the values achieved using the cuff/stethoscope auscultation method and are within the specified EN 1060-4 standard limits. • If the cuff causes any discomfort during the measurement, press the “START” button to turn off the unit immediately.
Warranty The warranty for this blood pressure monitor is valid for any error on the part of the manufacturer under normal use for 3 years from the date of purchase. If your unit does not function properly due to defective parts or assembly, we will repair it free of charge. With the exception of the battery and cuff, all parts of the unit are subject to this warranty. Damage caused by improper handling of your unit is not guaranteed.
Information you should know before operating the unit Fluctuation and variation in blood pressure The following chart shows possible blood pressure fluctuations during a 24-hour period. mmHg systolic diastolic The following factors will influence blood pressure measurement results and cause variations: GB • Bathing • Breathing • Conversation • Drinking alcohol • Exercise • Moving • Mental tension • Eating • Temperature changes • Thoughts • Smoking etc.
About the unit LCD Display M EM Memory STA RT access for power supply cuff On/Off Button The cuff is designed to fit arm sizes between 22 and 30cm (8.7 to 11.81 inches.
Preparation for use Installing/ Replacing batteries 1. Insert the batteries into the battery compartment matching correct polarities “+” and “-”. 2. Replace all batteries if the low battery indicator appears. 3. Remove the batteries if the unit will not be used for a long period of time. 4. REMOVE all of the BATTERIES when utilizing an optional AC adapter. Note: It is recommended that the same type of alkaline batteries be used to avoid incompatibility. Rechargeable batteries with a voltage of 1.
Preparation for use Posture during measuring 1. Sit upright and ensure that the cuff is at heart level. Relax and retain a natural posture during measurement. 2. Measure and record blood pressure at the same time every day to establish your blood pressure pattern. AC adapter (accessory) Use the device only with a medical approved stabilized AC adapter (6V, DC, 600mA). Note: 1. No batteries are required during operation using the AC adapter. 2.
Operations Setting the clock and date 1. Clock Mode Once you install the batteries, with two “beep”, the LCD will display the time and date by turns. At the same time, the machine enters the Radio Controlled Clock Mode with twinkling. After the RCC receiving, the the RCC symbol machine enters the Clock Mode and the LCD displays the time and date by turns. And the COLOUR CHANGE LED will twinkle with the colour changed in random turn. 2. Radio Controlled Clock(RCC) Receiving GB a.
Operations 3. Manual Clock Adjusting Normally, the time and date can be adjusted by RCC signal automatically. But you also can try manual clock adjusting if no RCC signal or weak signal. a. When the machine is in Clock Mode, press the “START” and “MEM” button at the same time (abt. 2 sec.), the machine enters Forced RCC Receiving mode, then press “START” button, the machine enters manual Clock Adjusting Mode. b. The number of year will twinkle first.
Operations c. Once you choose the group, and if it already has memory, LCD will show the latest result with the LED indicator (picture 2). If machine does not have memory before, the LCD will show six “0”. d. One second later, LCD shows a single “0”. While the “down arrow” pic. 2 does not twinkle until the air pressure is stable, and then it begins to measure automatically. e. Then the monitor begins to pressurize automatically.

Operations Recalling memories a. Under the clock-displaying mode, press button “MEM” will enter the mode of recalling memories. LCD will show how many results it has in the current group. Now you can modify the current group number by pressing the “START” button, and confirm the current group by pressing the “MEM” button. b. When the group is selected, the average of last three records will be displayed. If machine does not have memory before, the LCD will show four “0”. c.
