Refer to section 17. Appendix for a complete troubleshooting guide on pairing the ECG device.
6.2 Preparing the ECG recording
Examine the ECG measuring unit and the electrode cable for externally visible damage. If any damage is noted, have the
unit repaired or replaced before using it. If the ECG cable for the BT12 shows any signs of damage, replace it before
using it.
Before using the ECG measuring unit, make sure that the expiration date of the adhesive electrodes you are using has
not elapsed and observe the user instructions for the electrodes.
Attach the electrodes to the corresponding places on the body of the patient (see Section 5.5). Then fasten the electrode
cable via the contact option for the snaps on the electrodes.
6.3 Switching the ECG measuring unit on/off
To switch on the ECG measuring unit, press the power button for 3 seconds. On power on the device carries out an
automatic self-test. If an error code appears on the display follow the instructions in Section 6.7 below and Section 8.
Fault Finding. The ECG measuring unit is ready for operation when the battery symbol and the loudspeaker symbol
appear on the display.
CAUTION:
Do not use the device if an error code is displayed, see section 6.7 for a complete list of error codes.
Briefly pressing the power button with the device switched on activates the backlighting of the display. This switches off
automatically after 5 seconds.
Pressing and holding the power button switches the ECG measuring unit off. An acoustic signal sounds when it does so.
6.4 Electrode contact
Fasten the electrodes to the patient (see Section 5.4 and 5.5). The ECG measuring unit automatically checks the contact
quality and indicates a poor electrode contact by flashing the respective point on the display. If one or more points flash
check the contact of the corresponding electrode(s) and replace if necessary. The ECG transmission begins when all
electrodes are connected. If one of these four electrodes R, L, F and N is removed or falls off during recording, the ECG
signal transmission is interrupted. The recording is not interrupted if one of the V leads comes loose.
6.5 Heart rate monitoring
The ECG measuring unit monitors the heart rate of the patient continuously after correctly applying the electrodes. The
heart rate is shown on the display, labeled “BPM”. In limited display mode, only the heart symbol flashes at the same rate
as the heartbeat. If the preset limits are exceeded or fallen short of, the device will emit a sound to indicate this. The
volume of this can be adjusted to 5 different levels or muted.
NOTE:
The sound volume should be set so that it can’t be missed.
6.6 ECG data transmission
The receiving unit establishes the wireless connection to the ECG measuring unit via the interface. Once the connection
has been established, there is a short beep on the ECG measuring unit. An existing connection is indicated on the
display by the “Radio active”
symbol. If the connection is lost because the user moves out of range of the receiver it
will emit a sound and the corresponding symbol disappears from the display.
NOTE:
If there is no data transfer within five minutes of activating the device the ECG measuring unit switches off again
automatically.
NOTE:
The range of the wireless transmission is approximately 10 m. Ensure that there are no obstacles between the
ECG measuring unit and the receiver unit to maintain a stable connection.
NOTE:
If the Bluetooth connection is interrupted for longer than 15 minutes the ECG measuring unit switches off
