Battery Life & Memory
Volatile memory temporarily holds any program
changes or settings not yet saved in a Custom
Program. 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
battery 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 pecu-
liarities in the nondiscrimination or pinpointing
(TRIGGER squeezed) modes. Symptoms may be
blaring or silent non-discriminate or pinpoint
modes, depth indication inaccuracies or general
abnormal operation. To correct such difficulties "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.
Chapter 2 DFX™ Batteries
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
overcharging with the QUICK option, is not re-
placed under warranty. Only cell failure through
normal use, or a defect due to a problem with a
White's warranted DFX
™
charger, is covered.
