4.3 Low Battery Warning and NiMH Recharging

When the batteries are reaching the point at which they will no longer

operate, the Eureka Gold will emit a distinct sharp “pip” from the speaker,

approximately every 30 seconds. Shortly after this, the threshold will

increase to a loud continuous signal that cannot be reduced by the threshold

control. When this tone is heard, it is recommended that the NiMH battery

pack be recharged or alkaline batteries be replaced as soon as possible to

avoid missing any targets. The NiMH battery pack can be recharged using

either the supplied mains powered charger or a 12V charger (available as

an accessory) that can be plugged into the cigarette lighter of your vehicle.

Caution: Check the mains charger voltage. Only use the appropriate mains

charger for the country you are in.

4.4 Using your NiMH Chargers

Plug the charger into the socket on the rechargeable NiMH battery pack,

and plug the charger into the power source and switch on. The car charger

has a red light that indicates that it has power. A green light will appear on

the battery pack during charging. A completely flat battery will take

approximately 12-14 hours to fully charge. The green light on the battery

pack will fade/dim once it is fully charged. A fully charged NiMH pack will

give between 15 and 20 hours detecting time, depending on the number of

targets found.

5. The Eureka Gold Controls

This section gives detailed descriptions of the controls of the Eureka Gold

detector and their functionality. Having knowledge of these controls means

that you will be able to achieve the best performance from your detector.

As you gain experience with your detector it may be useful to refer back to

this section.

The Control Panel of the Eureka Gold has been carefully designed,

especially the placement of the controls, so those you will need to use

most frequently are at your finger tips (see figure 12).

5.1 Volume Control

The Volume Control incorporates the On/Off switch. It is off when the

control is fully counter clockwise. Turn the Volume Control clockwise and

the Eureka Gold ‘clicks’ on.

This control sets a maximum limit on the loudness of the audio signal

obtained from various targets. If the Volume Control is close to the

maximum, the audio signal is proportional to the target signal level

(see figure 13). However, if the Volume Control is turned down, the audio

signal is the same for a smaller target, but limited for a bigger target.
