Thank you for your purchase, and welcome to the users of Cardy! Cardy is a high-reliability, high-tech device capable of monitoring your heart continuously, and provide you with information regarding the state of your heart and your circulatory system. Cardy also stores this information.

Cardy warns you immediately that you need medical attention if there is a change in your ECG. Your doctor can later analyze the data on his or her computer by downloading it from your Cardy. It is very easy to measure your ECG with Cardy. It is also durable if you follow these simple instructions:

• Always use Cardy with 2xAA batteries or compatible rechargeable batteries. Using Cardy with any mains adapter is PROHIBITED AND DANGEROUS TO YOUR LIFE. Always check polarity of the batteries when you replace them.
• Cardy is manufactured using durable and reliable components that can withstand smaller bumps. Dropping Cardy, however, can damage the device. If you experience any malfunction with Cardy, always turn to an authorized service center. Do NOT attempt to open Cardy as doing so voids your warranty. Protect Cardy from any fluids.
• When measuring your ECG with Cardy, go at least 2-3 yards away from electric devices that contain a transformer, such as a radio, TC, PC or a mobile phone, as these could interfere with the measurement and alter the results.
• Sit down to measure your own ECG. Choose a comfortable chair, and stay seated and relaxed during the entire measurement. If somebody else helps you with the measurement, lying down provides the best result. Relax your arms, your legs, and your whole body in both cases. Do not move or sigh during the measurement, try to breathe evenly, taking small breaths. Tuck the cables under your belt to prevent the cable from accidentally removing the electrodes.

Follow these simple steps to take your own ECG measurement at home:
Each step will be displayed on your Cardy (e.g. "Electrode #6 OK?"). You can respond by pressing a key.

Take off your clothes from the waist up.

Sit or lie down comfortably.

Place the 6 electrodes. Put the four limb electrodes as follows: two along your hips, and two along your shoulders, one on the left and one on your right. Put the fifth electrode on your left side below your left armpit so that it is midway between your armpit and your elbow. Place the sixth electrode by the left side of your chest bone at the same height as the 5th. Follow the illustration on the box, or consult your doctor about the proper placement of the electrodes. Do not place the limb electrodes directly on a muscle. Make sure that the free flap of the electrode sticker faces towards the middle of your body so that the clips are easy to lock.

Connect the patient cable to Cardy and the pins to the electrodes. Connect the red pins to the right side electrodes, and the black pins to the left side electrodes. Electrodes placed between your left nipple and the middle of the body constitute right side. The patient cable indicates pairing of the electrodes by the length of the lead: the longest leads go to the shoulder electrodes, while the shortest leads should be connected to the electrodes along your hip (remember: red to the right, black to the left). The two middle length leads connect to the chest electrodes.

Turn Cardy ON by pressing thebutton .
Follow the instructions on the screen.

" CARDY F23
where the number after "F" is the number of empty memory slots left for one ECG measurement each

1st measurement<"
press "Yes" button

"CARDY 6 electrodes OK?"
when you see this and the electrodes are in their place, press "Yes" button . Measurement begins and Cardy displays the following:

" CARDY Relax, measuring!"
Relax. In 5 seconds the following message appears:

"CARDY ECG sampling"
Relax during the measurement. Do not flex your muscles, do not breath too deep. Relax your muscles and breathe normally. After the 16-second measurement the analysis takes about another 10 seconds. After that, Cardy displays on of the following results:

No change
There is no need to visit your doctor unless other symptoms make this necessary.

Small change
Indicates a small change in your ECG that your doctor should see within a couple of days. Consult your doctor.

Big change!
Seek immediate medical attention!

After the ECG measurement, Cardy will offer a questionnaire regarding your symptoms and your cardiological well being. Answer the questions one by one with yes or no. Your answers will affect the analysis significantly, so make sure you answer all the questions as thoroughly as you can!

Measurement Error
During measurement Cardy checks the placement of the electrodes and the technical quality of the ECG. If the electrodes are not connecting well during the measurement, or the ECG is "noisy", an error message will appear after the ECG sampling:

"MEAS. ERROR CODE: 8"
(Most frequent error code is 8, but can be any number between 1 and 12.) Check the placement of the electrodes, check if all the pins are in place, make sure that you are not too near to an electronic device (such as a TV). If everything seems in order, press any key, relax, and repeat the measurement.

Useful Tips

Switching off:
Cardy switches off automatically after 3 minutes of inactivity (except for "Cardy Online" status that overrides automatic shutdown.) In order to preserve the battery, you can manually switch off Cardy by answering (No) when Cardy asks for a new measurement. Cardy will ask "Are you sure?" - just press the (Yes) button to turn off your Cardy.

Replacing the battery:
A standard alkali battery has an approx. 250 measurement lifetime. A 1000 mAh rechargeable battery can power Cardy for about 120 measurements. After turning on your Cardy, a message will appear if the battery is low.

Restarting Cardy (RESET):
Complex electronic devices in Cardy are sensitive to external noise such as static electricity, electromagnetic waves close to electronic devices. If for any of these reasons Cardy should "freeze" - meaning that the display would not change after 30 seconds, you can reset (reboot) Cardy as follows:

a. Press and hold the switch on key
b. Press and release the key
c. Release switch on key

Capacity:
Cardy has a memory capacity to hold 24 measurements. When the 23rd memory slot is full, Cardy will warn you by displaying "Last". After this, Cardy will only store a new measurement if there is a change in your ECG. "Full" will be displayed - you can still take a measurement, but you cannot store the results. Please visit your doctor who can download the measurements and free up your Cardy's memory.
