WAX CHASSIS
The
circuit boards used in these models have been processed using Lead Free Solder.
The boards are identified by the LF logo located close to the board
designation.. The servicing of these boards requires special precautions to be
taken.
It
is strongly recommended to use Lead Free Solder material in order to guarantee
optimal quality of new solder joints.
Due
to the higher melting point of Lead Free Solder the soldering iron tip
temperature needs to be set to 370 degrees centigrade.This requires soldering
equipment capable of accurate temperature control coupled with a good heat
recovery characteristics.

How
to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth ground. If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms.

The unit
contains a self-diagnostic function. If an error occurs, the POWER LED
will automatically begin to fl ash. The number of times the LED fl ashes
translates to a probable source of the problem. A definition of the
POWER LED flash indicators is listed in the instruction manual for the
user’s knowledge and reference. If an error symptom is difficult to
reproduced use the Remote Commander to display the record that is stored
at the internal NVM to specify the cause of the failure.
Diagnostic Test Indicators
When an error
occurs, the POWER LED will fl ash a set number of times to indicate the
possible cause of the problem. If there is more than one error, the LED
will identify the first of the problem areas. If the errors occur
simultaneously, the one that corresponds to the fewest flashes is
identified first. Results for all of the following diagnostic items are
displayed on screen. No error has occurred if the screen displays a “0”.
