I. ASSEMBLY
1. Assemble the 3 piece adjustable handle; make sure the button
snaps into one of the holes. To change length, depress the button
and twist handle. Snap button into new hole.
2. Connect coil lead to control box. It is extremely important this is
done correctly:the “female” coilconnector has a channel that must
match up with the ridge on the “male” connector on the control box.
3. Adjust D-Handle and Control Box to comfortable position.
NOTE: The large loop in the search coil lead (Shown in Picture)
must be maintained. This minimizes damage to the cable during
frequent adjustments of the search head position.

II. BATTERY CHECK
The unit was checked out and completely operational when sent
from the factory. Transit time and storage may degrade the battery
charge. If this is the case, the battery should be topped off before
use.
To check battery charge: turn MODE switch to BATT position. If
the needle on the meter is high in the GREEN area battery is
charged; when the needle drops close to or is in the red area, it
needs to be recharged.
Directions to recharge the battery are in section V
(MAINTENANCE / SERVICE, paragraph A).

III. OPERATION OF UNIT
After the satisfactory battery check:
a. Turn MODE switch from BATT to RUN
b. Position detector in start position so magnetic field can align
itself correctly.
c. The meter needle will move to midscale after two full scale
deflections within about 4-6 seconds.
d. The unit will sound for a few seconds as it warms up and
creates a magnetic field.
e. The POWER lamp will switch from RED to GREEN and the
sound will stop*
f. The unit will be ready to operate in about 2-3 more seconds.
*Under some extreme temperature change conditions the sound
may continue as intermittent “grunts” for another minute or two.
NOTE: Random movement of metal detector will cause the
detector’s magnetic field to scramble causing the unit to “trip.”
If the unit is false “tripping” due to a scrambled magnetic field,
turn it off and begin start-up process as stated previously.

ENVIRONMENT
SCAN IN A “METAL FREE” ENVIRONMENT
Remember that a metal detector will not only detect metal in the
log, or lumber, but in the surrounding area as well. DO NOT place
logs on reinforced concrete pad or on ground surfaces containing
buried metal such as pipes. Using the P-4000, scan the area for
buried or hidden metal. Once you know the area is clear of metal,
begin scanning the material.

INDICATIONS OF METAL DETECTION
A. If metal is being detected a sound will be heard –a small piece
of metal will produce a small movement of the needle and a
short chirp of sound.
B. Detection of a large or particularly dense metal object may be
indicated by the power indicator light turning RED, meter
needle movement to the FAR RIGHT and a CONSTANT
ALARM sound.
HOWEVER: Check that this is not a “false” indication. Turn
unit away from scanning area. If unit settles down and resets
itself, scan area again. If the metal detector acts in the same
manner, a large metal object is being detected –this is a
normal reaction for the Metal Detector. If unit does not settle
down, RESET by turning unit off and going through start up
procedures as stated previously.
TO RESET THE UNIT
To RESET, turn MODE switch to OFF, wait 1 to 2 seconds, then
turn MODE switch to RUN.
NOTE: If the detector is set on a metal floor or near any other
large piece of metal for a time while the system is in RUN mode, it
will be necessary to perform a RESET action to remove the large
error voltage that develops. If a RESET is not performedit willtake
upwards of two minutes for the unit to restore itself to proper
operation.

DAILY OPERATION SETUP
1. Turn MODE switch to BATT position to observe battery charge
level.
2. Adjust sound volume to comfortable level.
3. Turn MODE switch to RUN position. When LED Lamp indicates
GREEN, and sound is silent, unit is ready to operate.
4. Adjust sound VOLUME as needed.
OPERATION IN A NOISY ENVIRONMENT
Sound level is adjustable from 0-100db. When using the unit in a
noisy environment, it may be advantageous to use the supplied
earphones.
CAUTION: To prevent ear damage when using earphones make
sure VOLUME control is fully counter-clockwise before switching
unit to RUN. After unit is active, turn VOLUME control to a
comfortable sound level.
TEMPERATURE CHANGES
The unit will automatically compensate for any long-term drift due
to temperature changes. To minimize the effect of drastic fast
temperature changes, store unit in a location with similar
temperature as working environment.

SUGGESTED METHOD FOR SCANNING LOGS
NOTE: In most cases scanning of a log cannot be done in one
pass. Please follow suggested scanning methodbelowandconsult
sensitivity chart in Section IV (Specifications).
1. Place search head close to the log surface and scan the entire
length of the log as shown in diagram.
2. Move to other side of the log and repeat step 1.
3. Roll log over as required to expose unscanned surfaces. Scan the
rest of the circumference of the log covering the complete surface
of the log.
This procedure will ensure that the metal detector scans the entire
surface of the log

SCANNING STANDING TIMBER
Search Head position
iseasilyadjustable. To
rotate the SearchHead
for vertical scanning,
hold firmly and rotate
D-Handle and Control
to desired position.
COMMON USER PROBLEM
TheMODE switch is sensitive to over-torqueing. The switch wiring
configuration does not allow for extra room to move in either
direction beyond the three designed spots: OFF, BATT, RUN.
Twisting too far will damage the unit, making it necessary to repair.
NOTE: Obvious excessive torque damage to the switch wiring
constitutes operator damage, and is not covered under Warranty.

V. MAINTENANCE / SERVICE (In House)
A. RECHARGING THE BATTERY
Plug charger into 120 V wall socket. Insert charger
connector into the receptacle on the rear oftheP-4000
control box marked CHARGER.
If the battery is fully discharged, it will take 14 or more
hours to fully recharge.
Unit may be left on the charger continuously when not
in use. The LED light becomes BRIGHTEST when
the battery is LOW. When the unit is fully charged the
LED light will become DIM.
B. BATTERY PACK REPLACEMENT
To replace the battery pack, loosen the two screws
securing the batterycompartmentaccessdoorlocated
at the rear of the control instrument. Grasp battery,
push on battery and lift, then pull to remove. Unplug
old battery pack. Install new battery pack and close
compartment door.
CAUTION: Handle battery pack with caution. In the unlikelyevent
a short develops or the battery pack is damaged it could cause
excessive internal heat buildup.
NOTE: Use only a RENS supplied battery charger for the
rechargeable battery pack.
