as low as is possible; to avoid masking the smallest and deepest desired

targets.

Ground Balance

This knob is used to set the balance of the CREDO DDM to suit the soil

conditions on any given site.

Threshold and Auto Mode

This knob sets the level of the threshold tone. The CREDO DDM may be

operated in silent mode, with no audible background tone or with this tone

set to give a slight tone level. In order to readily discern the faintest and

smallest of signals, operation with a slight background tone is

recommended.

The Threshold control knob is combined with a switch that enables the

Auto function. When the Threshold knob is turned fully anti clock wise the

switch will click and the Auto function will automatically set base levels for

the Threshold, Discrimination, Ground Balance and Iron Rejection controls

(those controls will not work manually unless the Auto Mode is turned off

from the Threshold knob). In Auto mode, the Sensitivity level is

recommended to be set to minimum.

Once the Auto function is turned on three LED lights will indicate that

Ground balance, Discrimination and Threshold are automatically controlled.

Sensitivity

This knob controls the level of sensitivity of the responses. The sensitivity

level setting chosen will depend on the soil conditions but, in general, the

highest possible setting should be used. On contaminated or mineralised

sites, it may be necessary to reduce the sensitivity to avoid some false

signals.

Volume and Power On/Off switch.

This knob sets the volume of the tone and responses and it is used also to

turn on/off the CREDO DDM. This knob should always be used for setting

the volume. Any volume control on the headphones should be set to

MAXIMUM.

When the Power is turned on an LED light above the Volume control knob

will indicate that detector is turned on.

Multitone.

This knob activates and adjusts the audio discrimination option and gives a

high-pitched tone response for non ferrous and low-pitched tone for ferrous

(iron) responses.
