PROGRAM SETTING
The programs are set in "Program" mode indicated by "P" letter displayed at "Program / Frequency„ display (4).
The instrument is automatically set up in this mode after initialization. You can also switch to this mode by pressing
"P/F" push-button (2). Press push-button (3) to set A program. Hold the push-button pressed to speed up adjustment.
FREQUENCY SETTING
Set the frequency in 'Frequency" mode indicated by letter "F" displayed at "Program / Frequency" display (4). Press
"P/F" push-button (2) to enter this mode. Press push-buttons (3) to set frequency in the range of 1.0 - 60 Hz. Keep
push-button pressed to change data continually. Up to 20 Hz you can set frequency in steps of 0.1 Hz, above 20 Hz
you can set frequency in steps of 1 Hz.
BTL-09 enables you to generate pulses with fixed and varying frequency. Average value of generated frequency is
seen on "Program/Frequency" display (4). If you wish to generate pulses of stable frequency, continue directly to set
therapy time. When pulses with variable frequency are needed, set magnitude of frequency change:
Press "Select" push-button (9) to get to frequency change mode (wave swing). The control light under Time / WS
display (8) indicates Hz. Press push-buttons (7) to set frequency on Time / WS display, in 0.1 Hz steps for up to 10
Hz, and 1 Hz steps from 10 Hz. During generation the frequency changes around average value of about set value
with the period of 90 sec. maximum. Generated frequency is moving between 1 - 60 Hz.
TIME SETTING
Therapy time is shown on Time / WS (8) display; the control light "min" below is on. If the control light "Hz" is on,
switch the instrument into the time setting mode by pressing "Select" (9) push-button. To set the time (in steps of
5 minutes), press push-buttons (7). Maximum therapy time is 90 minutes (with limits described in the section "Limits to
maximum intensity and therapy time"). During generation the time is counted-down in steps of 1 minute. The unit
makes a sound signal when the set time has elapsed.
INTENSITY SETTING
Intensity of magnetic field is shown on "Intensity„ display (12). Intensity displayed is the maximum intensity
at applicator’s surface. Intensity around individual applicator is described below. Maximum reachable intensity
depends on the type of applicator, program and therapy time set – see the "Limits to maximum intensity and therapy
time“ section. If solenoids are used, maximum intensity is around 12 mT, with other applicators the intensity is
at maximum of 20 mT.
Solenoids have lower maximum intensity values, yet the set intensity is spread nearly everywhere inside solenoid.
Other applicators have higher intensity limits but the intensity is concentrated solely around surface and further from
the surface (around 10 cm) it rapidly decreases.
Set the intensity by pressing push-buttons (10). Intensity is set in steps of 1mT (or 5% in case of use of adapter plug).
Keep the push-buttons pressed to decrease or increase value continuously. When intensity value is set (either in mT
or in %), signal light under "Intensity„ display (12) is on. You cannot set intensity if an applicator is not connected or if
both applicators are not connected to adapter plug.
Limits to maximum intensity and therapy time
Maximum intensity depends on type of applicator, program and therapy time. Some of the combinations do not allow
setting maximum intensity. If higher intensity is required, decrease the time of therapy or use a different program.
Intensity can be set during short or zero time period. If -- during the intensity increase -- an acoustic signal is heard
and yellow control signal at the top of bar-graph is alight (14), the therapy time will be limited, i.e. the therapy period
cannot be set to maximum possible value.
Magnetic induction if adapter plug is used
If you use adapter plug, up to 4 applicators can be connected to the unit. If you connect two applicators to one
channel, the limits described above have to be taken into account. Two applicators connected to one outlet have the
same program (frequency) set. Also the intensity of magnetic field (in %) is set for both applicators. However, intensity
in mT does not have to be, in case of use of two different applicators, identical!
