The performance of the unit may be affected by excessive temperature, humidity or altitude.

Commissioning

Before you start working with boso TM series devices, you should charge the batteries supplied. To do this, proceed as described in section ”Changing and charging the batteries”. Then install the boso XD profile manager. This software enables the programming of the blood pressure monitor and the evaluation of the stored data.
Selection and connection of the cuff on boso TM series devices
Cuff selection
Only original cuffs CA91, CA91R, CA92, CA93 and CA94 must be used.
The cuff must be selected according to the printed arm circumference.
Connecting the cuff
The air connection plug of the cuff tubing is screwed directly into the air connection socket of the blood pressure monitor (see Fig. 4).
Attachment of the protective covers (optional)
If necessary, you can also use protective covers (see section Accessories) to protect against soiling.
Put on the protective covers as shown below:

Pull the cuff through the tab of the protective cover.

Attach the protective cover to the cuff with the Velcro fasteners on the inside.
Care instructions for protective covers: machine wash at max. 60 °C

Attaching the cuff

Place the cuff on the unclothed upper arm so that the white marking lies on the arteria brachialis. For most people, blood pressure is higher on the left arm, so blood pressure is measured on the left arm. If the blood pressure is higher on the right arm, it should be measured on the right arm.
The cuff should be approx. 2-3 cm above the crook of the elbow. The cuff should not be too tight, about two fingers should still fit between the arm and the cuff.
After the end of the measurement, the blood circulation must not be impaired by the cuff. Place the cuff tube over the shoulder (see fig. 4). Fix the cuff tube to the shoulder with tape. The blood pressure monitor is carried in the pouch either on an existing belt or with the included carrying strap.

Carrying out measurements with boso TM series devices
After the cuff has been properly put on, a test measurement can be triggered on the boso TM series device by means of the START/STOP button (measurement is only displayed if the device has been programmed accordingly). If the display is off, activate it by pressing any button. If this measurement is successful, the automatic interval function (see below) can be started. The sample measurement is included in the evaluation.
Please note that the oscillometric measurement method can lead to measurement inaccuracies in some types of patients. Persons with cardiac arrhythmia, arteriosclerosis, circulatory disorders, diabetes or pacemaker wearers should have a comparative measurement taken with an auscultatory device before starting the measurement. This also applies to women during pregnancy.
External disturbing influences, such as movements of the measuring arm, disturbing vibrations, e.g. due to driving or the use of public transport during the measurement, can lead to incorrect measurements. For this reason, the record kept by the patient must be viewed and included in the evaluation of the measurement results.
Starting the automatic interval
To start the automatic interval, press and hold the black AUTO button until “ ” appears in the blood pressure monitor display and is acknowledged by a short signal tone (after approx. 5 seconds).
If the device is operated in “Sleep button” mode, the patient must press the black AUTO button before going to sleep. The display shows ” ” for automatic and “ ” for sleep mode. After getting up, the black AUTO button must be pressed again. The “ ” in the display disappears.
Automatic adjustment of the pump-up level (only in automatic interval mode)
The boso TM series device automatically pumps up to the required pressure level. If this inflation height is not sufficient, the unit automatically inflates again approx. 60 mmHg above the original inflation level.
Limiting the maximum pumping level
The device of the boso TM series has the option of limiting the inflation height. For the corresponding procedure, please refer to the boso XD profile manager instructions for use. Performing a manual measurement A manual measurement can be started by the patient at any time in addition to the automatic measurements. This can be sensible following physical or emotional stress. To do this, activate the display, then press the white START/STOP button.
Aborting measurements
To cancel the measurement, the white START/STOP button on the boso TM series must be pressed.
If the measurement is to be taken at a later time, a manual measurement can be started at any time using the white START/ STOP button.
Ending the measurement and transferring the measurement data
As soon as the device is removed from the patient after the 24-hour measurement has been completed, the automatic function must be switched off. To do this, press and hold the black AUTO button until the ” ” disappears from the blood pressure monitor display (approx. 5 seconds).
Then connect the boso TM series device to the computer using the USB connection cable. Transfer the data according to the instructions for use boso XD profile manager.
After transferring the measured data, it his highly suggested to delete the data memory.

Changing the batteries

We recommend changing the used battery pack after each 24-hour measurement and replacing it with the freshly charged battery pack. To prevent data loss, the data stored in the boso TM series device is buffered by an internal battery. This battery is automatically charged via the battery pack. With a fully charged battery pack, the data remain
stored for approx. 10 days. To fully charge the battery when using the unit for the first time, switch on the unit with fully charged batteries for approx. 24 hours.
To change the batteries, proceed as follows (see fig. 5):
Open the battery compartment cover (step 1)
Remove the empty batteries (step 2) and reinsert the charged batteries (step 3) (note polarity!) (Step 4))
Close the battery compartment cover (Step 5)

Insert the rechargeable batteries into the charger and plug it into a power socket. If the blue LED lights up, the battery packs are being charged. The charging process takes roughly 11 hours for a fully charged battery pack. After 13 hours, the charger automatically switches off the charging process.
Important note regarding battery charging
To ensure proper functioning of the boso TM series device for more than 24 hours, use only rechargeable batteries with the following ratings: min. 1900 mAh; 1.2 V; NiMH or batteries (Type AA 1.5 V).
In addition to the two rechargeable batteries required for the power supply, the device of the boso TM series also contains an internal battery to save the programme setting in the device.
To avoid loss of programming and stored readings when the internal battery is discharged, please observe the following procedure:
Insert charged batteries into the unit even when it is not in use.
The state of charge of the internal battery is thus constantly kept at a high level. If the power supply to the internal battery is interrupted, the settings of the boso TM series device will be lost after approx. 10 days.
Before placing the unit on a patient, please replace the batteries in the unit with a set of freshly charged batteries.
If the batteries are short-circuited, they may become hot and cause burns and scorching damage to the unit.
Do not touch the batteries and the patient at the same time.

Longer storage of the device

If the unit will not be used for a long time (4 weeks or more), remove the batteries to prevent possible damage due to leakage.
Before the device is then attached to a patient again, the internal battery must be charged and the device reprogrammed.
Insert freshly charged batteries.
Please leave the battery packs in the device for two hours. The internal battery is recharged during this time.
Reprogram the device.
Before attaching the device to a patient, replace the batteries with a set of freshly charged ones.

With P as the nominal power of the transmitter in watts (W) according to the transmitter manufacturer’s specifications and d as the recommended protective distance in metres (m). The field strength of stationary radio transmitters is lower than the compliance levelb at all frequencies according to an on-site investigationa.
Interference is possible in the vicinity of units with this symbol.
NOTE 1: For 80 MHz and 800 MHz, the higher value applies.
NOTE 2: These guidelines may not apply in all situations. The propagation of electromagnetic waves is influenced by absorption and reflection from buildings, objects and people.
a The field strength of stationary transmitters, such as base stations of radio telephones and land mobile services, amateur stations, AM and FM radio and television transmitters, cannot theoretically be predicted exactly. To determine the electromagnetic environment due to stationary HF transmitters, a site survey is recommended. If the determined field strength at the location of the boso blood pressure monitor exceeds the compliance level specified above, the boso blood pressure monitor must be observed with regard to its normal operation at any application location. If unusual performance characteristics are observed, it may be necessary to take additional measures, such as reorienting or relocating the boso blood pressure monitor. b Over the frequency range from 150 kHz to 80 MHz, the field strength is less than 3 V/m.
Recommended safe distances
between portable and mobile HF communication devices and the boso blood pressure monitor. The boso blood pressure monitor is intended for operation in an electromagnetic environment in which radiated HF disturbances are controlled. The customer or the user of the boso blood pressure measuring device can help prevent electromagnetic interference by maintaining minimum distances between portable and mobile HF communications equipment (transmitters) and the boso blood pressure measuring device as recommended below according to the maximum output power of the communications equipment.

Rated power of the transmitter| Protective distance according to transmission frequency m
---|---
W| 150 kHz to 80 MHz
d = 1.2 √P| 80 MHz to 800 MHz
d = 1.2 √P| 800 MHz to 2.5 GHz
d = 2.3 √P
0.01| 0.12| 0.12| 0.23
