In this situation, it often helps to reduce the Volume / Sensi-
tivity setting, so changes in loudness are easier to discern.
Also, the thumbwheel may be used to reduce the loudness
of the HOUND 3 in quiet office surroundings, so its use is
less obtrusive to nearby workers.
6.5: Earphone Jack (G)
The earphone jack accepts a standard 1/8" (3.5mm) mini-
plug. This type is often used with portable music playing
devices. The earphone may be either a stereo or mono type.
For best results, the lead wire should be shielded to reduce
the possibility of feedback occurring between the lead wire
and the HOUND 3’s probe. When the plug is inserted into
the jack, the HOUND 3’s speaker is turned off, and the sound
can only be heard through the earphone.
To use the earphone, set the HOUND 3’s Volume / Sensitiv-
ity thumbwheel to minimum, plug the earphone into jack,
and press the Power button. Adjust the thumbwheel for a
comfortable sound level in the earphone.
Helpful Hint:
Setting the Volume / Sensitivity thumbwheel to minimum
prior to using the earphone, as previously described, can
often save the user from a jarring experience. Sounds that
are not very loud in the speaker, can be very loud in the
earphone. While the HOUND 3 does provide some compen-
sation for this, the earphone loudness can varying greatly
depending on the earphones actually used.
