The Location ID Entry Screen
If location ID is active, enter your mile or kilometer position on the pipeline and press the button
labeled “OK”. If location ID is not active, the unit will immediately begin watching for a pig passage.
When recording has been initiated, the display will return to the main screen with two small differences.
The REC icon will have changed to one that reads “STOP REC”, and text will be displayed that
indicates that the unit is waiting for a pig passage and has seen zero thus far. Figure 20 is a picture of
how the main screen should look when the receiver is waiting for a pig passage:

The CD42-R Waiting to Record a Pig Passage
At this point the receiver is waiting patiently for a pig passage to occur. When a pig passage is
detected, you will hear a series of rapid beeps indicating that a recording has begun. If the unit has been
in screen blank mode, it will turn the screen and back light on as necessary so that an operator, if
present, can view the passage as it occurs. Once the pig and transmitter have traveled out of range, the
unit will issue a slower series of beeps to indicate that the recording process is over. Once the unit has
been set up to record pig passages in this way, it will continue to do so until its memory is full, or 99 pig
passages have been recorded.
Note:
Do not turn the CD42 receiver off during the recording process - always wait until the pig has
passed and the unit issues the slower series of beeps to turn off the power. If the unit is turned

position.
