How to Use the Device (ATP-C70)︱Instructions for Operating and Attaching the Device (ATP-C70)
12︱AT-Patch User Manual
■Instructions for Operating the Device (ATP-C70)
①The device (ATP-C70) is initially packaged in Sleep Mode and delivered to the customer. Patient
who wishes to attach the device should press the Power Button, #❸in [Figure 1.2], for 3 seconds,
upon which the green LED blinks twice and a long “beep” sound occurs once. The device is now in
Active Mode.
②Once the device (ATP-C70) is attached and connected to the App (AT-Note), it begins storing
measured ECG signals in the internal memory. The device continues to store the ECG signals for
the duration of use, and automatically goes into Sleep Mode after use. NOTE: If there is no App or
AT-Report (PC S/W) Hookup connection for about 8 minutes after Active Mode is on, then the
device goes into Sleep Mode following a single red LED blink and three “beep-- bebeep--” sounds.
•During the initial connection process, the connection between the device (ATP-C70) and AT-Report
(PC S/W) Hookup or the App must be established at least once. Otherwise, the connection process
is terminated as described in ②, and the device will not operate normally. After the initial
connection is established, ECG measurement is performed normally even if AT-Report (PC S/W)
Hookup or the Bluetooth paring for the App is terminated for some reasons.
- The device cannot be used with a PC or smartphone that does not support Bluetooth.
•The working status of the device (ATP-C70) can only be confirmed through the App's real-time live
monitoring or AT-Report (PC S/W) Hookup.
•Once the initial one-time connection is confirmed, AT-Patch is not terminated for the duration of use
(7 days).
- Physically turning the power off is not possible. Automatic Power-Off will occur after the duration
of use (7 days) has elapsed.
- In case the buzzer or the Red LED blink was missed after AT-Patch's duration of use has
passed, the App or AT-Report (PC S/W) Hookup can be used for confirmation.

■Instructions for Attaching the Device on the Body (ATP-C70)
►State of the skin before attachment
An area larger than the device (ATP-C70) attachment area needs to be cleaned on the patient's skin.
If body hair is abundant in the attachment area, shaving will be required to remove the hair.
NOTE: If a wound or bleeding occurs when removing body hair, the device should be attached after
the bleeding stops.
As demonstrated in the "confirm patch
attachment site" figure ❶, place the end of
the patch about a finger's distance below the
clavicle, and confirm the attachment site at a
45-degree angle.
If necessary, remove possible obstructions like
hair using a razor, etc. as shown in the "shave
the patch attachment site" figure ❷.
Figure 1.3 Attachment preparation step –Confirming attachment site
To produce the accurate ECG signals, clean the attachment area using alcohol swabs to remove any
possible obstructions such as dead skin cells, etc. from the skin surface. Then, fully dry the skin for at
least one minute before attaching the device (ATP-C70).
Cleansing the patch attachment site with alcohol
As illustrated in Figure ❸, cleanse the attachment site to remove dead skin cells and possible
obstructions by wiping horizontally, vertically and diagonally with alcohol cottons or swabs. Then,
fully dry for at least one minute to make sure no alcohol is left on the surface.

►Attaching the device to the body
After pressing the device (ATP-C70) Power Button, attach as follows
Figure 1.5 How to attach ATP-C70
1. As shown in [Figure 1.5] ❶, remove the tape designed to protect the patch side. Once the
protective tape is removed, attach the device to the body.
2. As shown in [Figure 1.5] ❷, attach the device so that it is tilted toward the left nipple area, using
the line in the middle between the two clavicles as the center. However, if the patient has a fuller
chest or if diagonally attaching the device is difficult, the part directed toward the nipple should be
raised a bit higher and then attached.
3. As shown in [Figure 1.5] ❸, remove the bottom protective tape from the ECG Sub Patch, then
attach it in line with the Main Patch. Apply even pressure on the attached Sub Patch.
4. As shown in [Figure 1.5] ❹, evenly apply pressure on the patch so that no gap occurs
when the device is attached to the body, and then remove the protective tape.
