A license-free transceiver is a radio set that requires no license that can be easily
used from the day it is purchased. Though it was originally designed and
developed for leisure use, now it is often used in business scenes as well. As a
result, license-free transceivers are now required to not only be lightweight and
reliable (waterproof and durable) for business use, but also to assure performance
for extended periods of time with one dry cell. To meet such market needs, we
carried out initiatives to reduce the consumption current by several mA by
reviewing the transmission and power source circuit, reducing the operating
voltage of the internal circuit, and changing the amplifier for driving built-in
speakers to a class-D amplifier that consumes little current. By installing an “eco
mode,” a function to control power consumption, in our license-free transceivers,
we also achieved an extended operation of about 72 hours with three AA size
batteries under our measuring conditions when an optional clip microphone with
earphones is used.
At the product development stage, based on the principle of recycle and
reduce, JVCKENWOOD is promoting designs that allow easy separation of
resign parts and metal parts by reconciling ease of assembly with ease of
disassembly through the adoption of a hooking structure that uses hooks
rather than screws in addition to reducing the types and the total number
of screws. We also trimmed the total number of items of parts and sharply
reduced the size and mass of chassis parts and printed circuit boards
through the development of mechaless models exclusively for digital audio
equipment. We achieved a reduction of about 23% in the number of
items of parts and that of about 45% in mass in mechaless models when
compared with our CD receiver models. In addition, the size of packaging
boxes was cut by some 30% in terms of volume ratio thanks to the
downsizing of products, which contributed to the reduction of product
transportation energy, while environmental impact was reduced as a result
of a reduction of the mass of corrugated cardboards and buffer materials
that are subject to recycling.
Since headphones directly touch human bodies when they are used, JVCKENWOOD promptly
worked on reducing harmful chemicals. We
reduce harmful chemicals under a thorough
management system, actually screening
phthalates to verify that no controlled
substances are contained in our products, not
to mention globally developing products that
conform to the RoHS directive. JVCKENWOOD
provides “peace of mind” to customers by disclosing the Green
Procurement Guideline, which specifies forbidden substances and
substances that require management, to suppliers in order to have
them deliver parts and materials in line with this Guideline.
