BLUETOOTH OPERATION

All gC.A.T models offer Bluetooth connectivity to Radiodetection’s C.A.T Manager mobile app for Android available from Google’s Play Store.

gC.A.T4 models from August 2016 onwards are also compatible with Apple devices. 

To quickly identify if a gC.A.T4 is iOS compatible you can check if the sentence “Works with Android and iOS devices” is present at the bottom of the label directly above the battery compartment.

GPS/GNSS OPERATION

gC.A.T4 models are equipped with an internal GPS/ GNSS positional receiver module which adds positional data to the internal logging system.

When the unit’s trigger is pulled, the positional module activates and will try to lock on to the satellite positioning system. The locking time will vary depending on a number of factors such as the area being located, the weather conditions and the time of day, but generally this should be less than 2 minutes.

The GPS icon on the screen will flash until the module has acquired a satellite lock, at which point it will remain constantly visible.

NOTE: When a valid depth measurement is displayed, the GPS icon will momentarily disappear from the screen.

If a GPS lock is present when the trigger is released the gC.A.T positional module will remain active for a predefined period of time (GPS Remain On, 3 minutes by default) to enable an immediate GPS lock next time the C.A.T is used.

If a GPS lock has not been acquired when the gC.A.T4’s trigger is released, the positional module will first remain on for a predefined period of time (GPS Lock Seek, 3 minutes by default) or until a lock is acquired. When the lock is acquired, the gC.A.T4 will log the positional data and maintain a GPS fix for the GPS Remain On period.

GPS Lock Seek and GPS Remain On time periods can be customized using the C.A.T Manager software application.

Refer to the C.A.T Manager manual for further information.

WARNINGS

Signal Overload

If the C.A.T4 is used in areas where very large power signals are present, the signal bargraph will flash. In this condition the sensitivity control and depth function will not operate and you are advised to try lifting the C.A.T4 to bring it out of the overloaded condition or use the C.A.T4 in a different location.

When taking depth readings

Conductor out of range.

Selected mode does not support depth estimations

Not possible to indicate depth eg, high levels of electrical interference.

StrikeAlert

The optional StrikeAlert feature warns the operator of shallow pipes and cables. To check if your C.A.T4 has StrikeAlert, look for the StrikeAlert Activation sticker on the side of the C.A.T4.

When a shallow cable or pipe is detected in Power, Genny or Avoidance Mode, StrikeAlert flashes an asterix and sounds a distinctive warbling audio tone. StrikeAlert is not activated when tracing Radio signals.

The unit StrikeAlert status can be changed using C.A.T Manager, and is momentarily displayed at start up:

Indicates that StrikeAlert is not active

Indicates that StrikeAlert is active

eC.A.T4 and gC.A.T4 models

	Warns that a C.A.T is being used too far from the vertical or moved too quickly for reliable cable or pipe location.
	On startup, warns that the C.A.T is due for service in less than 31 days, followed by number of days until service is due.
	If C.A.T is CALSafe™ enabled, the unit is past its calibration due date. Return for immediate service.
All eC.A.T4 and gC.A.T4 models will log warnings when displayed.

Deactivating warnings

If required, for example if it is necessary to locate at an angle, the StrikeAlert and SWING warnings can be temporarily disabled by pressing and holding the depth button for the duration of the battery test bleep at switch on. eC.A.T4 and gC.A.T4 models will log this action.
