7 .4 Operating custo cardio 300 On/off switch The large black button on the device switches the device on and off. Only switch the device on shortly before starting the recording. After the recording, the device does not need to be switched off. It deactivates automatically after 15 minutes of inactivity. The maximum duration of operation is ten minutes in Bluetooth mode at a sampling frequency of 4 khz. (Four hours in WLAN mode) Afterwards the battery needs to be recharged. If the device is operated in battery mode, the maximum duration of operation is five hours in Bluetooth mode. (1.5 hours in WLAN mode) LED display When the device is switched on, the upper LED indicates the state of charge of the accumulators/batteries. Accumulator mode Green / flashing green: Good / good and charging Yellow / flashing yellow: Medium / medium and charging Red / flashing red: Low / low and charging Battery mode Green: Good Yellow: Medium Red: Low If the LED is red and flashing quickly, the accumulator must be recharged / the battery replaced. The middle LED indicates whether the USB connection is active between the device and the PC. If there is a connection, the LED is illuminated continuously again. If there is no connection, the LED is dark. The lower LED indicates whether the radio connection is active between the device and the PC. It illuminates in blue when the device is in radio mode. The device can then be connected via BT or WLAN (depending on the version) or is already connected. This LED flashes as soon as data is transmitted via radio. If there is no connection, the LED is dark. MHW 0013 DK 1716 Version 001 3/0/018 custo med GmbH [] Resting and Stress ECG hardware, custo cardio 300 page 7

8 Switching on custo cardio 300 If you touch the capacitive on/off switch on custo cardio 300, all LEDs first start to flash and then the device switches on and can be connected Electrode control After the device is switched on, the LEDs in the LED ring indicate the electrode system quality. If the electrodes are not applied on the patient, all LEDs are illuminated in red. If the electrodes are applied to the patient correctly, they are illuminated in green. The same applies, even without a connection to custo diagnostic. Recording can start. Starting/stopping recording on the device The start/stop and blue LED ring functions depend on the settings in custo diagnostic and only work if the device is connected to custo diagnostic and a patient was already selected for a new recording: An x-second ECG is set in custo diagnostic (x is usually ten seconds). If the start button is then pressed on the device, a ten second recording starts. The blue LED ring indicates the progression of the recording, i.e. it is dark at zero seconds, half illuminates at five seconds and fully illuminated at ten seconds. In custo diagnostic, the ECG recording is configured to be stopped manually. The blue LED ring behaves as described above for the first ten seconds. Afterwards, it illuminates in the reverse order and needs a further ten seconds per additional cycle. The recording can be stopped by pressing.

11 .6 Instructions for the recording.6.1 Instructions for stress ECG with treadmill The patient should ideally be wearing running shoes or trainers. The patient should not hold onto the handles of the treadmill during the recording process. This will lead to muscle tension which will affect the ECG signal. Missing skin tension, in interaction with shoulder movement, will increase artefacts in the ECG signal. The extremity leads should if possible be applied on taut skin areas in order to avoid excessive movement artefacts and therefore interference in the other terminal lines. During the ECG recording, the electrode leads must not come into contact with the patient, the treadmill or other objects. Normal electrode application Artefact reduced electrode application Artefact reduced electrode application results in smaller amplitudes in the extremity leads.
