A Message from...
Kenneth R. White
Congratulations, and thank you for choosing the TM 808.
As an avid detectorist, I commend you for making an excellent choice
in deep seeking equipment. White's continually strives to achieve
performance and reliability above and beyond your expectations.
Your new TM 808 has been hand built and carefully tested. Properly
cared for, it will last years.
The following instructions are intended to familiarize you with this
ne detector, and give you a good understanding of the basics. Obviously, there is no substitute for eld experience. Practice using your
detector in the eld, and study this manual carefully. Before long
you may be able to teach the experts a thing or two!
People use White's metal detectors to nd valuables every day.
Regardless of a metal detectors performance, it is the operator who
makes the critical decisions that result in great recoveries. A metal
detector is simply a tool which greatly increases the capabilities of
the user to nd such valuables. Knowing your detector, and researching good places to use it, are key elements to successful metal
detecting.
Another important factor today is obtaining permission prior to
searching private property, and the necessary permits prior to
searching publicly owned lands. These steps, as well as relling dug
holes, and removing trash you discover, will go a long ways toward
protecting the hobby from future restrictive legislation.
We know in a very short time you will be using the TM 808 to help
you nd valuables. We are proud to continue White's tradition of
high performance and reliability with your TM 808.

size batteries. Alkalines are recommended as they supply more consistent power
for longer time periods. Rechargeable "C" size batteries may also be used in this
holder, although they will need to be removed from the holder for recharging.
Using The Standard Battery Holder:
1)
Remove the battery holder lid by applying gentle pressure down on the two
locking tab openings on one side (just enough so that they unlock), flip the pack
over and apply gentle pressure on the other two locking tab openings. The lid will
then slip off.
2)
Insert the small foam squares inside the two springs on the lid, and
the two in the holder, to prevent loss of spring tension
3) Note the position of each cell. The flat side of each battery cell fits against one
of the four springs. There are two springs on the lid, and two in the case. The bat-
teries fit alternating +, -, +, -.
4) Install new "C" cells. Caution: If the cells are put in backwards the detector
may blow a fuse. Fuses can only be replaced by authorized service centers.
5) Line up the locking tabs on the lid with the locking tab openings on the battery
holder. Snap the lid and holder together.
6) Open the battery compartment door on the side of the control box nearest the
rear antenna, by pulling the battery door knob.
