SE™ Operator’s Manual 39
If the temp dot changes to silver or gray, then the transmitter has been exposed to heat but not in excess
of the specifications. If the temp dot is black, then the transmitter has been exposed to temperatures in
excess of 220°F (104°C) and can no longer be used. The DCI warranty will be void for 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, in-
adequate mud flow, and poorly mixed mud are some of the factors that can contribute significantly to the
overheating of a transmitter.
