operating manual & user's guide

Connection to the mains

Read the "Safety Instructions" before using instrument!

Make sure that the mains switch is at "0". Connect mains cable to the connector on the rear panel with mains 230 V/50 Hz. Switch the main switch to "1". The program number, the preset treatment time, and the ultrasound frequency are lit up on the display.

Choose the irradiation surface area and the emitter head (1 cm2 or 4 cm2). Connect the emitter head with emitter head connector on the front panel. Never change emitter heads during ultrasound generation. Change emitter heads only if the instrument is switched off with the START/PAUSE button (17). Use RESET button if you begin therapy with another patient.

Choosing the ultrasound frequency

Use the FREQUENCY push-button (15) to choose the 1 MHz or 3 MHz frequency. The green diodes (13), situated to the left of the FREQUENCY button, indicate which of the two frequencies is activated. Both frequencies can be applied with either emitter head sizes. Choose a 1 MHz frequency if you wish to therapeutically affect deep tissues and a 3 MHz frequency for superficial tissues.

Choosing and connecting emitter head

Two emitter heads of either 1 cm2 or 4 cm2 can be used with the BTL-07p.

Connect the emitter head to the Connector (11, 21). Connect the 1 cm2 emitter head to Connector (11) and the 4 cm2 head to Connector (21). The LED diode (19) indicates which emitter head is in use. Both emitter heads can be used for either continuous or pulse modes and for both frequencies. The emitter head must be connected before intensity of acoustic output is set. The therapy cannot start without connecting and identifying the emitter head.

The red diode on the emitter head indicates insufficient contact between the emitter head and the tissue. If contact is insufficient, the control light lights up red.

The countdown on the TIME display (3) stops. Power absorption (indicated by the light blinking) stops. Therapy is interrupted until contact is restored.

If there is proper contact, the control signal on the emitter head will light up green.

Choosing PPR (pulse-to-period ratio)

Different pulse-to-period ratios are related to different ultrasound thermic effects. Continuous ultrasound deeply heats tissues. A 1:2 or 1:4 PPR ultrasound only has a moderate thermic effect and 1:8 or 1:16 PPR ultrasound has an athermic.

Use the DUTY CYCLE push-button (9) to set the PPR. The activated PPR is indicated by the green diode (17).

Choosing pulse frequency

The pulse ultrasound (1:2 - 1:16 PPR) allows the user to choose one of the pulse frequencies and the time duration.

The BTL-07p uses 50 Hz and 100 Hz pulse frequencies. Press the PULSE FREQUENCY button (16) to switch between the two frequencies. The activated pulse frequency is indicated by the diode next to the PULSE FREQUENCY button (14). Impulse and pause duration of both frequencies are specified in the following tables.

Frequency 50 Hz, period duration 20ms			Frequency 100 Hz, period duration 10ms
Duty cycle	Impulse	Pause	Duty cycle	Impulse	Pause
	duration	duration		duration	duration
1: 2	10 ms	10 ms	1: 2	5 ms	5 ms
1: 4	5 ms	15 ms	1: 4	2.5 ms	7.5 ms
1: 8	2.5 ms	17.5 ms	1: 8	1.25 ms	8.75 ms
1: 16	1.25 ms	18.75 ms	1: 16	0.625 ms	9.375 ms

Choosing intensity of acoustic output

Press up/down arrow push-buttons (7) to set intensity. Continuous mode employs intensities up to 2 W/cm2, pulse mode up to 3 W/cm2 (in steps of 0.1 W/cm2). Pressing down the up/down push-button will increase or decrease intensity.

BTL – 07p

operating manual & user's guide

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/cm2 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 (-).

operating manual & user's guide

Starting the combined therapy

Set the instruments after they are connected. Set all needed parameters on the BTL 07p and press the START/PAUSE button (17). Press the STOP button (V/mA) (18) to set the voltage (the V control light is on). Choose the program and set the therapy time. Apply the electrode and the emitter head to the treatment area. The moment the emitter head touches the skin, the ultrasound will start and the time will begin to count down. Press the button (19) on the electrotherapy unit to set the voltage and start the combined therapy. Caution: Keep the ultrasound emitter head on the treated area during the therapy!

Ending the combined therapy

After the pre-set time has elapsed and the START/PAUSE button (17) on the BTL-07p has been pressed, the combined therapy stops. If there is a need to stop or interrupt the application before the pre-set time elapses, press the button (18) on the BTL-06 before removing the emitter head or the electrode from the skin.
