Volume Gain

Range: 1–30

Factory Preset: 24

The Volume Gain controls the amplication

of a target’s audio response, relative to the

target signal strength. The Volume Gain

control is the Audio setting that is most

similar to volume adjustments in other

devices (e.g. radio or television

volume controls).

With a setting of 1 the target signal will not

be amplied. Weak target signals will sound

quiet, medium target signals will sound mid-

range and strong target signals will sound

loud. There will be greater dierentiation

between target signal strengths, however,

weak signals will be harder to hear.

Volume Limit

Range: 0–30

Factory Preset: 30

The Volume Limit sets the maximum volume

of target signals. When detecting, the sound

produced by a distant target will be quiet.

As the coil gets closer to the target, the

volume increases until it reaches the Volume

Limit setting.

A high Volume Limit will allow a greater

dierence between a small and large target.

The Factory Preset for Volume Limit is set

at an appropriate level for E-Trac’s built-in

speaker. If the audio is too loud whilst using

headphones, use the Volume Limit setting to

reduce the audio volume.

To adjust the Volume Limit:

1 Press the Menu button

2 Scroll across to Audio (using the Right or

Left Navigation button)

3 Scroll down to Volume Limit (using the

Down Navigation button)

4 Press either the Left or Right Navigation

button to change the Volume Limit

5 Press the Detect button to exit the Menu

and resume detecting

A low Volume Limit will not allow a great

dierence between a small and large target.

With a setting of 15, the audio response

will be partially amplied. Weak to medium

strength signals will sound louder, but strong

signals will not sound much louder than

medium signals as the volume reaches the

Volume Limit.

With a setting of 30, all target signals will

be amplied to a loud audio response. At

this setting there will be less dierentiation

between medium and strong signals, but

weak target signals will be easier to hear.
