Mobile 2 - Service Manual 27
5.1. GENERAL
1) The following information is intended to help in
troubleshooting the major components of the
INTELECT MOBILE 2 at “Board Level” only.
These tests are FACTORY standard testing
procedures and methods, used at the end of
manufacturing before shipment of any INTELECT
MOBILE 2.
2) Due to the complex nature of the technology utilized
by DJO, the recommended troubleshooting
techniques are built to determine “Bad Board” and
board replacement only. No board component level
troubleshooting is recommended/authorized nor will
information or parts be supplied by DJO. Any board
component level troubleshooting performed will be
at sole risk and liability of the Service Technician
performing such troubleshooting techniques.
3) Once an electronic board has been determined as bad,
refer to the appropriate Removal and Replacement
Section of this Manual for proper replacement.
5.2. Special Tools, Fixtures, & Materials
Required
1) Some of the tests require the use of special tools and
fixtures. These will be listed at the test section where
they are required. Testing with any other special tool
or fixture other than those stated could give wrong
readings or test results. Always perform the tests
exactly as stated to ensure accurate results.
2) Some of the special tools or fixtures required may be
obtained through DJO Service Department.
3) Scope and other standard test equipment settings will
be detailed for every test section to help in
performing the test with FACTORY standards and
ensure proper readings.
4) Troubleshooting and repair of INTELECT MOBILE 2
and Accessories must be performed only by
authorized technicians trained and certified by DJO.

4) Digital Multimeter
5) STIM lead wires (Accessory)
6) Ultrasound Applicator (Accessory)
7) Ohmic Instruments UPM DT 10 or DT 100
Ultrasound Power Meter
8) Degassed Water (<5 ppm) for Ultrasound Power Meter
5.4. RECIPE FOR DEGASSED WATER
• Boil Distilled Water for 30 minutes
• Place water in a non-porous container and immediately
close hermetically
• Allow to cool to room temperature of approximately 70
°F (21 °C) May be refrigerated to aid cooling time
NOTE :
Do not use Tap water or Distilled water in the Ultrasound
Power Meter. Use only Degassed Water in order to
obtain correct test results. The chart below illustrates
the oxygen content of Degassed, Tap and Distilled Water.
5.5. FULL FUNCTIONAL TESTS
Perform the tests found in this section to check Full
Functionality of new Intelect Mobile 2 and accessories.
Before releasing the device to the end-user, the Final
test must be done, passed at 100 % and registered in
the doc (Page 50, 56, 64 or 67)
5.6. US CALIBRATION REQUIREMENTS
The US Applicator has been calibrated during the
manufacturing process and doesn't need any
calibration during the product life.
BUT the replacement of some parts in the applicator
requires a calibration after repair.
Refer to page 28 for more information
The calibration must be performed only by a repair
center trained and equipped with a US power meter
.
A measurement of the power output is mandatory
after repair (Final Test)
For US Applicator Operation refer to page 47
