  •  Do not allow the electrodes of the device to come into contact with other conductive parts (including earth).
  •  Do not store the device in the following locations: locations in which the device is exposed to direct sunlight, high temperatures or levels of moisture, or heavy contamination; locations near to sources of water or fire; or locations that are subject to strong electromagnetic influences.
  •  Vital signs measurements, such as those taken with this device, cannot identify all diseases. Regardless of the measurement taken using this device, you should consult your doctor immediately if you experience symptoms that could indicate acute disease.
  •  Do not self-diagnose or self-medicate on the basis of this device without consulting your doctor. In particular, do not start taking any new medication or change the type and/or dosage of any existing medication without prior approval.
  •  The device has no alarms and will not sound if the measurement reading is too low or too high.
  •  Check the SpO2 sensor application site every 6-8 hours to determine the positioning of the sensor and the circulation and skin sensitivity of the patient.Patient sensitivity varies depending on medical status or skin condition. For patients with poor peripheral blood circulation or sensitive skin, inspect the
    sensor site more frequently.
  •  Do not use the Oximeter on the same hand/arm when using a blood pressure cuff or monitor.

 Daily Check
About Daily Check
Daily Check measurement is a function that combines the measuring of ECG (Electrocardiograph), SpO2 (blood oxygenation) and systolic blood pressure. It takes only 20 seconds to collect your vital signs before giving you vital signs readings and your health evaluation.
Using Daily Check
To start a Daily Check, follow the steps as below.

  1.  If you have not created user, then please follow the instruction in [Settings Section] to add your user account.
  2.  Tap the <Daily Check> icon in the middle of the screen.
  3.  choose the right user.
  4.  Hold the device according to the instruction, keep the device at the same level as your heart, and keep stable posture and stay calm. Don’t exert too much pressure on the ECG electrode, which may result in EMG (electromyograph) interference.Just hold gently and ensure good contact with the ECG electrode. Do not exert
    pressure on the finger that put.
    1. Viatom-Checkme-Pro-Health-Monitor-image-4 Put the right forefinger into the built-in SpO2 sensor. Use the finger nail to squeeze the edge of the SpO2 sensor cover, then move in upward to the left to raise it up as shown below.
    2.  Press the right thumb on the right electrode.
    3.  Press the right middle finger on the back electrode.
    4. Press the left electrode to the left palm.
  5. Once the device detects stable waveform, it will automatically start the measurement. The countdown bar moves from left to right.
  6.  When the bar is fully filled, the device will analysis your data, and then show the measurement result.

Viatom-Checkme-Pro-Health-Monitor-image-5

Daily Check provides the trending graph of heart rate, SpO2 and blood pressure. To view the trend, tap the button, then select one record, and then tap the button.
BP Calibration
Warnings and Cautionary Advices

  •  For a given user, it is suggested to make BP calibration every three months.To get blood pressure readings, this device should be calibrated by a doctor with a traditional cuff blood pressure (BP) meter. Because of individual differences, each user must make his/her own calibration before using Daily Check to measure or track the
    blood pressure. The calibration should be performed when the user is under calm status.

To calibrate with a cuff BP meter, follow the steps as below.

  1. Select the <Settings> icon, select <BP Calibration>, and then choose the right user.
  2. Ensure that the cuff and the Checkme monitor are at the same level as your heart.Then start the blood pressure measurement from the cuff BP meter.
  3.  Press the button on the Checkme screen, and start the Daily Check measurement.
  4. When the blood pressure measurement is finished, manually input the readings of systolic pressure reading in the Checkme.
  5. Repeat the calibration once again by following the above steps.

Where, P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey a, should be less than the compliance level in each frequency range b.

Interference may occur in the vicinity of equipment marked with the following symbol:

 

 

Note 1: At 80 MHz to 800 MHz, the separation distance for the higher frequency range applies.

Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection

from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.

b Over frequency range 150kHz to 80MHz. For Resp field strength

should be less than 1V/m.

RF communications equipment and the device
The Health Monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Health Monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the monitor as recommended below, according to

the maximum output power of the communications equipment.
