Time setting
The therapy time is shown on the TIME display (3). Press the up/down arrow push-buttons to increase or
decrease time (4). The time is adjustable in steps of 0.5 minute up to 5 minutes and in steps of 1 minute up to 25
minutes. The maximum application time is 25 minutes. Hold the up/down push-button pressed to increase or
decrease time.
Ultrasound generation
Generation of ultrasound begins after the following operations have taken place:
Connect an emitter head to the instrument.
Set intensity and time. READY control light should light up. If it does not, check the emitter head (19) connection
and the head type (5). Try the other emitter head (8).
Press START/PAUSE push-button (18). The set time must not be 0. The time display starts to count/down the
pre-set time.
If there is sufficient contact between the emitter head and the skin, the “Program” display will stop showing the
program number and will start to count the amount of absorbed energy. The lowest green light in the CONTACT
row will light up (10) and the light in the TIME and INTENSITY decimal boxes will start to blink. The columnar
graph (10) and the emitter head control light both monitor the quality of contact during application. If contact is
insufficient, diodes light up red. If this happens, moisten the skin with more ultrasound gel.
A cold emitter head can also cause insufficient contact. In this case set the intensity to 0.1 W/cm
2
and generate
ultrasound for approximately 1 minute to warm up the head. Then set the intensity. If there is insufficient contact
between the head and the patient, the unit stops. If there is proper contact, the therapy continued. All parameters
can be changed at any time.
Indication of stationary waves
Any ultrasound application to a bone or bony area situated just under the skin (condyles, epicondyles, ankles)
may, if the emitter head is not moved sufficiently, result in interference between a reflected wave and an arising
wave arising (stationary wave). Consequently, there are "peaks of intensity". A peak of intensity is an area, which
is exposed to intensity higher than the preset intensity level. There is an increased local temperature in these
areas.
BTL-07p emitter heads have a very low BNR. Further more, the BTL-07p features an optic indicator to signal
stationary waves, placed on the Bar-graph (10) (the orange LED diode). Respond to this signal by immediately
removing the emitter head from the application site in order to eliminate any risk of soft tissue damage.
Interrupting the therapy
Pressing the START/PAUSE push-button (18) immediately interrupts the therapy. The time countdown stops and
the pre-set intensity level, as well as the amount of absorbed energy, do not change. To continue therapy, press
the START/PAUSE push-button again. To start a new treatment, set the time and start the ultrasound generation.
Selecting the program
The unit has pre-set programs for ultrasound and combined ultrasound/electrotherapy. The list of programs and
procedures can be found in the user’s guide. Press button (2) to select the program or diagnosis. Any parameters
can be changed before starting the application. Press the START/PAUSE button (18) to start the therapy.
Saving personalised programs
The BTL-07p enables you to save your own programs, which can be stored under codes 80-99. Set all
the parameters. Press and hold the START/PAUSE button. After 2 seconds the bar-graph (10) blinks and there is
an acoustic signal. Programs are stored when the unit is turned off.
Combined ultrasound/electrotherapy
The BTL-07p allows the user to apply ultrasound and electrotherapy at the same time. The ultrasound instrument
can be connected to the BTL-06 electrotherapy unit. Do not connect the BTL-07p to electrotherapy units
manufactured by other companies.
Connecting the units
Place the BTL-06 on the ultrasound BTL-07p. For combined therapy, the units are connected with a special cable.
Plug the cable connector of an ultrasound emitter head into the outlet on the front panel (21). Insert the cable for
combined therapy into the electrotherapy unit outlet (channel B for voltage mode). Insert the red banana plug into
the BTL-07p outlet (20). Connect the electrode to the green banana plug. The ultrasound emitter head then
serves as the anode (+) and the electrode as the cathode (-).
