Senior Solutions™ Therapy System
5 TROUBLESHOOTING
A. General
The following information is intended to aid
in troubleshooting the major components
of the Senior Solutions Therapy System to
“board level” only. These tests are FACTORY
standard testing procedures and methods
used at the factory before shipment of any
Senior Solutions Therapy System.
Due to the complex nature of the technology
utilized by Chattanooga Group, the
recommended troubleshooting techniques
are to determine “Bad Board” and board
replacement only. No board component-
level troubleshooting is recommended nor
will information or parts be supplied by
Chattanooga Group. Any board component-
level troubleshooting performed will be at
sole risk and liability of the Service Technician
performing such troubleshooting techniques.
Once a particular PC Board has been
determined as bad, refer to the appropriate
Removal and Replacement Section of this
Manual for proper replacement.
B. Special Tools, Fixtures, & Materials Required
Certain tests require the use of special
tools and fixtures. These will be listed at
the particular test where they are required.
Testing with any other special tool or fixture
other than those stated could give erroneous
readings or test results. Always perform the
tests exactly as stated to ensure accurate
results.
Any special tools or fixtures required can
be obtained through Chattanooga Group
Service Department.
Scope and other standard test equipment
settings will be listed for each test performed
to aid in performing the test to FACTORY
standards and ensure proper readings.
The troubleshooting and repair of the Senior
Solutions Therapy System, Modules, and
Accessories should be performed only by
authorized technicians trained and certified
by Chattanooga Group.

Senior Solutions Therapy System Ultrasound
Applicators (Accessories).
Dielectric Withstand (Hi-Pot) and ground
resistance tester.
NOTE:
Adjust Dielectric Withstand tester to indicate
fault with 120 k Ohm Load across the output
when at specified test voltage.
Milliohm Meter.
Ohmic Instruments UPM DT 10 or DT 100
Ultrasound Power Meter.
Audio Signal Generator, B-K Precision,
Model 3001.
Dissolved Oxygen Test Kit. Used to test
oxygen level of degassed water.
Degassed Water (<5 ppm) for Ultrasound
Power Meter.
D. Recipe(s) for Degassed Water
Boil distilled water for 30 minutes. Place
water in a non-porous container and
immediately cover with cellophane. Allow to
cool to room temperature of approximately
70 °F (21 °C). May be refrigerated to aid
cooling time.
Bring distilled water to a boil. Place the
container under vacuum for 5 to 10 minutes.
NOTE:
Two liter soft drink bottles are ideal storage and
transport containers for degassed water as they are
designed to keep oxygen out. Do not allow aeration of
degassed water during transport or filling of the power
meter.
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.
WATER TYPE ppm of Oxygen
Degassed per recipe 1 or 2 Less than 5 ppm
Tap Water Up to 35 ppm
Distilled Water Up to 20 ppm
