How the BT-3 Works
Corrections
When the collar detects a bark or howl it generates an annoying “correc-
tion” which always consists of an audible tone and, if enabled, a low cur-
rent shock to the dog’s throat area. The dog learns that the annoyance
goes away when they stop barking or howling.
Progressive Corrections
The number and frequency of corrections progressively increases if the
dog keeps barking or howling. The rst correction is just a short tone to
get the dogs attention, but following corrections add shock (if enabled)
and multiple pulses if the dog continues to bark or howl.
Automatic Correction Reduction
As the dog’s barking slows the processor automatically reduces the fre-
quency and intensity of the corrections. When there is no barking/howl-
ing for 30 seconds, the correction is reduced to it’s minimum.
Panic Recovery Period
If the dog happens to panic and bark or howl uncontrollably for more
than 15 seconds, the processor disables all corrections for a 20 second
recovery period to let the dog calm down.
Bark vs. Noise
Detection of a bark is relatively reliable in the BT-3 due to the internal
digital processing. However any very loud sound that has the same
amplitude envelope and duration of a normal dog bark can be miss-
interpreted as a bark and generate an unnecessary correction. This
is confusing to the dog. Therefore when you rst start using a BT3 we
recommend you avoid locations where there is chance of loud sounds
triggering the collar. This includes areas such as automotive repair
shops, and construction zones.
The No-Bark Reward
If your dog has not barked in a long time, the rst bark or loud noise will
not trigger a correction. This feature prevents generation of an unneces-
sary correction to a random event such as something falling and creating
a loud noise. This feature is implemented in the Normal and Anti-Intruder
TM
modes, but not the Howl-Prevention mode.
Continuous Status Indicators
During normal operation, the BATT and SHOCK lights will ash in syn-
chronization with every tone and shock correction respectively. This may
be used to visually observe the corrections if you cannot hear the tone.
