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.

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.
