Operating Procedures
The key to operating the heat seeker is to always keep it in motion when scanning. Set the gain control to proper gain. Point the
heatseekertoaneutralareawhere there are noknownheatsources. Turnon the unit whileobservingtheLEDdisplay, or listening tothe
earphone. Ifyou are watchingtheLED display,youwillsee the power-up sequence. If youare listening to theearphone,you will hear
the maximum pitched sound momentarily. With the unit on, scan back and forth from left to right. Scan at a moderate, even pace
making sure your sweeping motion is horizontally level. Scan horizontally, not vertically. Keep scanning in wide sweeps, much like
usinga flashlight. Now usethesameprocedureto scan anareawithaknown heat source. Remember to alwayskeeptheheatseeker in
motion. When you get a reading, keep scanning past the area. As you scan back and forth, you can pinpoint the area that gave you the
reading. The morevarianceintemperature between theobjectandthe surroundings, the furtheryoucandetect the object. If the object

What Affects The Detection of Heat?
This section will give you some guidelines on how weather and other environmental conditions affect infrared detection. Please use
theseguidelinesindeterminingwhat kindofrangetoexpect.
Ground cover, trees and other solid objects.
Althoughitisentirelypossibletogetagoodreading through some brush, tree cover,andothersimilarobjects,theruleofthumbis:
the more cover an object has, the less heat that can be seen by the detector. This also means that the denser the cover is, the shorter the
range of detection will be. A little common sense goes a long way here. Heat can be radiated through some objects such as leaves, but
the more of them that are between you and the object, the less heat that can be detected. A good example would be a deer lying in the
snow. If the deer hasabodytemperatureof100degreesitis going tobeeasytodetectonthecoldsnow. Ifthatsamedeerwascoveredin
a foot of snow, you would probably never see it. However, the deer could be found if there was a hole in the snow, allowing heat to
escape.
Temperature.
Inorderto detect an object, there mustbeadifferenceintemperaturebetweenitandthesurroundings. Again,commonsensegoes
a long way here. The greater the difference in temperature between the object and the surroundings, the further you can detect the
object. If the object is the same temperature as the surroundings, the detector has no way to determine it is there. The heat seeker can
detectchangesaboveandbelow thesurroundingtemperature.
Wind, rain, fog, and snow.
The general rule for these conditions is much the same for ground cover and trees. If the conditions are such that the heat is
blocked,itmaynotbe detected. Thismainlyappliestosnow,butallweatherconditionsshould always betakenintoconsideration.
Sunshine.
Although sunshine will not effect the operation of the heat seeker, keep in mind that when the sun heats an object, it emits infrared
energy. This means that any infrared detector may detect heat from rocks, trees and other objects. Stay in close so if you get signals
from these objects you can readily see what you are detecting. It is also a good idea to check the area from different angles to eliminate
thesesignals,andtomake sureagoodsignalwasnotmissed.
