E-Trac has a Battery Icon on the LCD that

indicates the present charge level, and

provides advanced warning of the need to

recharge or replace the battery. The Battery

Icon displays the battery charge level in

four segments.

As E-Trac operates, the segments of the

Battery Icon will decrease relative to the

voltage left in the battery. When the last

segment disappears, the Battery Icon will

begin to ash and the Battery Low sound will

emit every 20 seconds. If the detector is still

operating at this time the voltage will drop to

a point when a “FLAT BATTERY” message will

appear and the detector will turn itself o.

Note: The detector regulates the output voltage

so the performance of the detector will remain

the same regardless of the charge remaining in

the batteries.

To extend battery life:

– Use headphones. The speaker uses

signicantly more power than headphones.

– Turn o the Backlight. The Backlight

increases the power consumption by

approximately 8%.

– Turn the detector o when not in use.

The typical discharge times for both

good quality alkaline and Minelab NiMH

rechargeable batteries under constant use are

compared on the graph on p. 85. This graph

assumes the Backlight is o, and headphones

are used instead of the speaker.

Typical alkaline batteries will power E-Trac for

over 16 hours of constant use. The Minelab

NiMH 1600 Slimpack will power the

detector for over 14 hours of constant use

and the Minelab NiMH 1800 Slimpack for

over 16 hours.

Unlike Nickel Cadmium batteries, the Minelab

NiMH Slimpack DOES NOT need to be fully

discharged before recharging.

Whenever the detector has been unused for

a lengthy period, recharge the battery pack

to ensure full charge level. NiMH batteries do

not hold their charge when not in use.

Charging the battery for longer than 18hrs

will not damage the NiMH Slimpack.

When the battery voltage has been depleted

(indicated by the Battery Icon), Minelab

recommends the Slimpack be recharged, or

alkaline batteries replaced, as soon as possible

to avoid missing any targets.
