TROUBLESHOOTING

SYMPTOM

SOLUTION

The detector does not

turn on

 Ensure the battery is fully charged

 If battery is fully charged, contact your dealer to help resolve the problem

The detector turns on

but will not detect

metal

 Ensure the search coil is properly connected to the control housing

 Check the Sensitivity level – if set too low, detection depth will be greatly

limited

Target detection

appears on the screen

but there is no audio

signal

 Ensure the volume is not set too low

 Check to see if there are headphones connected to the back of the control

housing

 Plug in a set of headphones to see if there is a problem with the internal

speaker

 Ensure the wireless option has not been activated (see flashing icon on the

upper right side of the screen)

Excessive chatter or

false signals received

as the coil is swept

across the ground

 Reduce the Sensitivity level

 Try using the Frequency Shift function to minimize or eliminate the chatter

 Check the Ground Balance as ground conditions may have changed

 Try another part of the site you are searching – there may be a large number

of targets present

 Electrical interference in the area may be the cause. If reducing Sensitivity

does not help, you may need to come back at a different time to see if the

cause is no longer present.

Overload audio signal

 The overload signal indicates that the detected target is either very shallow or

very large. Try lifting the coil a few inches and recheck the area.

Target ID #”s and

audio tones jump

around

 Typically this indicates the coil is either passing over multiple targets, an

irregularly shaped object or trash. Turn 90 degrees and wiggle the coil across

the target side-to-side an inch or two. This will help you separate multiple

targets or determine if it is a larger piece of trash.

If the solutions above do not address the issue you are experiencing, try resetting the Q30 / Q30+ to its

factory settings. Turn the detector off and then hold the POWER touchpad for 5 seconds. All of the icons on

the screen will illuminate indicating the detector has been reset and this should have resolved your issue. If

not, service may be required. Contact your authorized service center for information on obtaining service.
