Minelab 4901 - 0059 quick start Adjusting Volume, Speaker/Headphone Volume

32VOLUME

Volume is the level of sound emitted by the detector when a target is detected. The Volume control limits the maximum volume of target signals.

The sound produced by a distant target starts softly. As you get closer, the volume level increases rapidly until it reaches the maximum level that has been set.

The sound produced by the detector in Pinpoint or Ground Balance will vary in volume and tone depending on the signal strength (from a target or ground mineralisation). This volume range is proportional to the maximum volume setting.

Speaker/Headphone Volume

The X-Terra 70 is able to save separate settings for both the speaker volume and headphones volume, switching from one to the other automatically as the headphones are connected

(Accessories, pg. 50).

When the detector battery is low (indicated by the low battery icon) the speaker volume limit will be automatically reduced. This saves battery power and extends detecting time.

You may choose to override this and increase the volume limit, but you then risk the detector shutting down sooner.

Press MENU SELECT and choose Volume.

Use the + and – buttons to adjust the Volume limit.

Press PINPOINT DETECT, to return to detection.

ADJUSTING VOLUME 33

Set the speaker volume without headphones connected. Set the headphones volume with the headphones connected. Use the simple detecting exercise (pg. 16) with different targets to confirm both the speaker and headphones volume settings.
