3. COLLAR FITTING
The receiver/collar should be fitted so that the surgical
stainless steel contact points press firmly against the dog's
skin. When properly fitted, you should be able to fit a finger
or two snugly in between the contact points and your dog's
skin. When properly fitted, the receiver/collar should not
move on the dog. The best location for the receiver/collar
box is either side of the dog's windpipe.
A loose fit can allow the receiver/collar to move around
on the dog's neck. When this happens, the contact points
may rub the skin and cause irritation. If the receiver/collar
is too tight, the dogs may have difficulty breathing.

4. HOW TO FIND THE RIGHT STIMULATION
The 640C unit comes with the rheostat dial on the
transmitter. The rheostat intensity dial controls the
stimulation level, with level 0 being the lowest level and
level 127 being the highest.
The level of stimulation best suited for your dog depends
on your dog's temperament and threshold for stimulation.
Always start at the lowest level and work your way up.
The appropriate level can be found when the dog responds
to the stimulation with a mild reaction, such as a tensing of
the neck muscles. The stimulation level may vary depending
on the training situation. When highly distracted, dogs will
require a higher level of stimulation.
NOTE : The stimulation intensity can be adjusted even
while the stimulation is in use.
5. TO MAXIMIZE THE DISTANCE
The 640C has a maximum range of 600 metres. The range
may vary depending on the way the transmitter is held.
Hold the transmitter away from your body to receive the
greatest range. For maximum signal strength, keep the unit
properly charged.
