Chapter 2 DFX™ Batteries

Battery Life & Memory

Volatile memory

temporarily holds any program

changes or settings not yet saved in a Custom Pro-

gram.

Short-term

or volatile memory is retained so

long as a good battery remains in the detector. To

recover volatile memory immediately squeeze and

release the TRIGGER once the detector is turned

ON. If the battery is removed all volatile memory

is lost.

Long-term

memory (programs saved in

Custom Programs) is automatically saved for up to

ten years regardless of whether a battery is in the

detector or not.

When using fresh batteries, the voltage will initially

check somewhere in the 10 to 14 volt area. Unlike

standard batteries, the rechargeable battery voltage

will quickly drop to between 9 and 10 volts and

plateau there for most of its life. Once the recharge-

able battery voltage drops below this plateau, it will

quickly drop below a usable voltage level (eight

volts) and thus require a recharge.

Low Battery

will

automatically appear on the display when the bat-

tery reaches eight volts.

Like a personal computer, there are times (such as

low battery conditions) when the microprocessor of

a metal detector becomes out of sequence with the

rest of the circuitry. This is often noted by peculiari-

ties in the nondiscrimination or pinpointing (TRIG-

GER squeezed) modes. Symptoms may be blaring

or silent non-discriminate or pinpoint modes, depth

indication inaccuracies or general abnormal opera-

tion. To correct such difﬁ culties "re-boot" by:

1. Install a good battery.

2. Turn ON wait for MAIN MENU to appear.

3. Open battery door and remove battery while

detector is still ON.

4. Wait one minute, reinstall battery, turn

detector ON, and check for proper function.

Use of maximum backlight may reduce battery life

by up to 50%, depending on battery type.

Rechargeable batteries gradually deteriorate. As

they age they do not provide the life-per-charge

they did when new. This is expected, and not

grounds for replacement under warranty. Addition-

ally, a damaged initial cell, which is caused by over-

charging with the QUICK option,

is not replaced

under warranty

. Only cell failure through normal

use, or a defect due to a problem with a White's

warranted DFX

™

charger, is covered.
