Safety and Care
***PLEASE NOTE: USE CAUTION WHEN PRESSURE TESTING. NEVER
INFLATE TO MORE THAN 15 PSI. DO NOT STAND IN FRONT OR ABOVE A
COMPRESSION PLUG OR ANY PLUG WHEN UNDER PRESSURE.
***PLEASE NOTE: IT IS EXTREMELY IMPORTANT TO ALWAYS TURN DOWN
THE VOLUME, REMOVE HEADPHONES OR USE MUTE FUNCTION ON LT1000
WHEN MOVING EITHER THE POOL SCOPE™, PIPE MIC™,
DECKPLATE, SOILPROBE, SLIDE MIC OR ANY COMPONENT FROM
ONE LOCATION TO ANOTHER. FAILURE TO DO SO CAN CAUSE SERIOUS
HEARING INJURY OR HEARING LOSS.
***AVOID STORING CABLES WITH TANGLES OR KNOTS. ALWAYS STORE
CABLES IN A LOOSELY WRAPPED COIL. PLEASE USE EXTREME CARE AND
KEEP THIS MANUAL HANDY FOR ALL USERS.
***LOWERING THE POOL SCOPE™ OR THE PIPE MIC™ TO THE
BOTTOM OF A POOL AND DRAGGING ALONG THE POOL FLOOR WILL NOT
DAMAGE THE UNIT.
***LEAKTRONICS COMPONENTS ARE DURABLE UNITS THAT WHEN
TREATED WITH CARE WILL LAST FOR MANY YEARS. EACH UNIT IS HAND
BUILT IN THE U.S.A. WHILE ALL COMPONENTS ARE MADE TO USE IN
HARSH ENVIRONMENTS, THE HEADPHONE, AMP OR BODY OF THE VIDEO
SCOPE CAN NEVER BE SUBMERGED. DOING SO WILL VOID THE
WARRANTY.
***ALL PRODUCTS INCLUDING THE LT1000™ AMPLIFIER, POOL
SCOPE™ AND THE PIPE MIC™ SHOULD BE WIPED DOWN WITH A DRY
RAG BEFORE STORING.

Change batteries with #2 Phillips screwdriver
***PLEASE NOTE: Mute button MUST be in off position (down) when powering
LT1000 amplifier on.
Battery installation and type:
We highly recommend using high quality alkaline battery, Energizer max or Duracell
Coppertop are recommended. To install battery, remove one set screw and pivot door
open by loosening other screw. Hold amp upside down, tap lightly and battery holder
should pop out. If it does not come out easily, grab with fingers and edge it out, being
careful not to pull too hard on two wire leads which attach battery compartment to amp.
Using a flat head screwdriver, pop batteries out of holder and replace properly as
marked. Gentry push battery compartment back into amp, DO NOT FORCE IT. Pivot
battery door closed and retighten screws.
Power ON/OFF, LED display:
Power ON & OFF is a simple toggle switch. Up is power on, down is power off. The
LED will light up when amp is turned on and will flash when battery power is low.
When battery power is very low light will go off, however amp will work. At this point,
battery must be replaced as soon as possible.
Mute button makes it easy to go from on location to another without having to adjust
volume or meter null. By placing the mute toggle switch in the up position, all sound
will be muted out, until it is switched off (put in the down position).
Meter Null / Sensitivity / Meter
Meter null is an adjustment knob which is used to get a baseline for background noise.
In order to use properly, with the sensitivity switch down, choose the listening devise,
start listening and watch the meter to see if there is any background noise. A 100
reading indicates that what you're hearing is inundated with background noise, or you're

hovering over the leak itself. Starting with the meter null notch facing up, turn the null
to the left to establish a noise baseline (low). You can then turn the meter to the right to
get a noise baseline (high). Turning the sensitivity switch on (up) will allow for a higher
and lower range.
Filter Switch (UP is on, DOWN is off)
By using the Filter Switch you are able to filter many different background noises.
Using the equipment as shown in previous pages, turning on the switch will dim out
many different kinds of background noises, traffic, lawn equipment, a/c units, etc.
Volume
Turn to the right to increase volume, turn to left to decrease. Always be sure to turn the
volume on the amplifier to the left (lowest setting) prior to each use or to powering on.
USEFUL TIPS: The LT1000 comes with 2 round rings located on either side to
be used with the strap (included). It is important to use this feature when using
around construction sites and wet locations to avoid dropping and becoming
damaged. Always carry a supply of fresh batteries. The Pool Scope™ and Pipe
Mic™ has certain voltage requirements. Once the batteries fall below the required
voltage, the signal to the headphones will cut out intermittently and/or distort. This is an
indication that the batteries should be replaced. All troubleshooting should begin by
replacing batteries with new, high quality alkaline batteries. If using noise reducing
headphones, always keep replacement batteries. As the batteries in noise reducing
headphones (such as Bose or JBL) expire, the signal heard will be intermittent and
distorted.
Troubleshooting
In the case that the pool scope or pipe mic begin to not function properly or if you
experience problems, always replace the battery in the amp with a new high quality AA
batteries. If you are using noise canceling headphones always replace with new batteries
if you begin to experience problems. As the batteries power fades, the signal will
become intermittent and subject to interference. New batteries will solve the problem. If
problems persist, test the unit with a new or another set of headphones. If a different set
of headphones corrects the problem, then the headphones or headphone cable are faulty.
Replace headphones. If the problem continues after replacing the headphones, contact
LeakTronics for assistance.
