Safety Precautions iii
Safety Precautions
Use Caution to Prevent
Hearing Loss
BluePack contains a headphone
amplier that is more powerful than
the typical consumer product.
JK Audio products are designed for
the broadcast industry. The broadcast
professional must be able to hear
headphone signals over the ambient
noise level. From the cheering crowd
at a football game to trackside at a
car race, the program material or cues
must be heard at high volumes without
distortion.
Road Safety
Never use headphones while driving
or cycling, etc. It can be dangerous
to turn up the volume even while
walking. Doing so may hinder your
hearing and can be hazardous on the
roadways or at pedestrian crossings.
Note: While BluePack was designed
to be very rugged and durable, it is not
waterproof and care should be taken to
keep the unit dry.

* HD Voice. While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD
Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives
voice a more natural sound, while the additional upper octave dramatically improves speech
clarity and intelligibility.
Wireless HD Calls. To take advantage of this extended bandwidth, both phones on the call
must support HD Voice, and both phones must be on the same carrier, in coverage areas
that support HD Voice.
