¾There is no sleep mode; therefore, the power supply must be turned off manually at the end of the day. Failure to turn off the power overnight can result in an overheated cable transmitter.
¾A low battery indication (BAT) could signify that another battery is needed.
¾The remote steering feature may be used.
¾The DataLog Mapping System may be used.
¾An extraction/insertion tool is provided to remove and install the cable transmitter in the housing. The cable transmitter’s wire must never be used to remove the transmitter.

Remote Display with Cable Transmitter Capability
The remote display used with the Cable Transmitter System has special components to accept pitch, roll, voltage, and temperature information directly off the wire from a cable transmitter. (When tracking a standard transmitter, the receiver sends the pitch, roll, battery status, and temperature information to the remote display using telemetry.)
The depth and left/right steering information, which is processed by the receiver, is sent to the remote display by telemetry. Therefore, the information on the remote display is a combination of information received from the cable transmitter and from the receiver. The receiver must be set to the same channel as the remote display.
A delta symbol or triangle in the top left window of the remote display indicates if it is operating in the cable transmitter mode. Temperature will be displayed in the top right window of the remote display following a 4°C increase. To view the cable transmitter’s temperature at any time, simply turn the remote display unit off and then on (do not turn off the power supply). The temperature will display in degrees
