Transmitter Overheat Indicator (Temp Dot)
Each transmitter has a temperature overheat indicator (temp dot) on the front end cap. The
temp dot has an outer yellow ring with a
1
/
8
in. white dot in the center.
Transmitter Temp Dot
If the temp dot changes to silver or gray, the transmitter has been exposed to heat but not in
excess of specifications. If the temp dot is black, the transmitter has been exposed to
excessive temperatures and can no longer be used. The DCI warranty does not cover any
transmitter that has been overheated (black dot) or had its temp dot removed.
Avoid transmitter overheating by practicing proper drilling techniques. Abrasive soils, clogged
jets, inadequate mud flow, and improperly mixed mud all contribute significantly to the over-
heating of a transmitter.
The Falcon transmitter stores the maximum temperature, which you
can view using the Transmitter Info function. Note that the external
temp dot can reach 220° F and turn black before the internal
temperature reaches 220° F.
