Transmitter
Batteries
The 15.00-in. (381.0-mm) transmitters require two C-cell alkaline batteries or one DCI SuperCell Lithium
Battery. The 19.00-in. (482.6-mm) long-range transmitter requires one DCI SuperCell Lithium Battery,
although two C-cell alkaline batteries will work for a very short period of time. The mini transmitter
requires one AA alkaline battery. DCI does not recommend using non-alkaline or rechargeable batteries.
The batteries are loaded into the battery compartment with the positive terminals going in first.
The amount of power remaining in the batteries is displayed on the depth and predicted depth display
screens (see Locating section). However, the SuperCell battery will display as fully charged until
moments before it goes dead. Therefore, it is necessary to monitor drilling hours when using the
SuperCell battery.
When using two C-cell alkaline batteries, it may be beneficial to solder or wrap the batteries to avoid
battery chatter in hard ground conditions.
Temperature Updates and Overheat Indicator
Transmitter temperature information is displayed both digitally and graphically on the receiver. When the
transmitter’s temperature increases, audible warning tones are emitted by both the receiver and the
remote display. Temperatures are displayed in degrees Fahrenheit (°F) when the depth measurement
mode is in English units, and degrees Celsius (°C) when the depth mode is in metric units.
Normal drilling temperatures range from 64°F (16°C) to 104°F (40°C). DCI recommends that you keep the
transmitter temperature below 104°F (40°C) by slowing penetration rates and/or adding more drilling fluid.
Each transmitter has a temperature overheat indicator (temp dot) located on the stainless-steel front end
cap. The temp dot on a new transmitter is white (see photo). If the temp dot is black, the transmitter has
been exposed to temperatures in excess of 220°F (104°C). The transmitter should then be deemed
unreliable and should not be used on further projects.
