Manual blood pressure measurement
If it seems necessary, the patient can start an additional, manual blood pressure measurement by pressing the
START button shortly. The result with a manual measurement marker will be stored in the memory of the device.
Typical causes for this use: dizziness, pain (angina pectoris or headache), palpitation.
Switching the device off
Press and hold the START button for more than 10 seconds then release it when two horizontal segments appear on
the LCD, this way BTL-08 ABPM will be switched off. If you do not release the button in 2 seconds after the two
horizontal segments appeared, the recorder will return to normal operation. This feature helps to avoid unintended
power-off. The device can only be switched on manually. While the recorder is switched off normal functions
are not available, even prescheduled measurements will not be triggered. Therefore switching off the device
is only necessary in case of valid reasons.
Switching the device on
BTL-08 ABPM is switched on to normal operation if the START button is pressed and held for more than 3 seconds. If
the device is switched off, no other functions are available.
LCD check
Press and hold the START button to light up all segments of the LCD to check if they all work correctly.
Battery voltage check
Press and hold the START button for more than 5 seconds to display battery voltage on the LCD (e.g. 2_64, equal to
2.64 V). After checking the voltage, please release the button, because after additional 5 seconds, the device may
turn off. The unit will then return to displaying time. The voltage for fully charged accumulators should be over 2.5 V,
and for fresh alkaline batteries over 3 V.
Set a patient event marker
The patient can mark any event without starting a manual blood pressure measurement by pressing the
MEDICATION button briefly. Typical causes for this use are taking medicine. The patient should be instructed to
record the reason for setting an event marker in a diary.
Mark time of going to bed and rising from bed
If this function is disabled during programming, the patient can press the DAY/NIGHT button to mark the times of
going to bed (in the evening) and rising from bed (in the morning).
Manual DAY/NIGHT shift
If this function is enabled during the programming, then the patient can manually shift the measurement frequency
period (day or night) by pressing the DAY/NIGHT button. The shift is available in the two hour period before the
prescheduled shift.
