Notice to SR390/SR450 User

"This wireless portable device has been shown to be capable of compliance for localized specific
absorption rate (SAR) for uncontrolled environmental/general population exposure limits specified in
ANSI/IEEE Std. C95.1-2005 and has been tested in accordance with the measurement procedures
specified in FCC/OET Bulletin 65 Supplement C (2002) and IEEE Std. 1528-2003. SAR Compliance for
body-worn operation is based on a separation distance of 1.4 cm between the rear of the unit and the
body."

ABOUT THE V.A.D.E.R. SYSTEM

The V.A.D.E.R. communication system was developed for professional use in mobile communications
within a small group that has tasks requiring high confidentiality. To secure the communication, the
V.A.D.E.R. radio features a scrambling transmission along with a high-speed frequency scanning that
makes group's communication hard to be intercepted.
The RF output power is selectable between LO (200mW) and HI (2W) according to the group's range of
activities. Minimizing the RF output power prevents detection and interception from outside of the
group.
The V.A.D.E.R. radio does not come with a built-in microphone or a speaker. You can use this radio by
connecting the external audio device either a Headgear or an Ear Microphone both applies Temco's bone
conduction technology. Neither the Headgear nor the Ear Mic prevents you from wearing a helmet.
Furthermore, neither device sets its microphone near your mouth. The system's complete face-free
configuration assists your active tasks.
A remarkable feature of the V.A.D.E.R. radio is to have the DSP (Digital Signal Processor) that makes
VOX (Voice Activation) work steadily even in highly noisy condition. This achieved to offer the
enhanced VOX that first meets the tasks of professional communications. The DSP activates the VOX
circuitry only when the input signal is recognized as the human voiced sounds, and switches the radio to
the transmit mode.
The DSP also enables to temporarily store the speech on memory and send them to transmit with a slight
delay.
This completely prevents clipping the voice syllable at the beginning of speech that the conventional
VOX currently in use could never achieve. You can also enjoy the noise cancellation function featured
by the DSP that suppresses noise elements through digital processing and creates the clear audio to
transmit. Along with Temco's noise-resistant bone conduction microphones, the higher the ambient noise
level is, the more you can feel its excellent performance.
The Radio Housing is made from aluminum alloy that allows the unit to be light but sturdy.
An easy detachable battery housing is made from reinforced polycarbonate resin that resists against heat
and shock. You can use rechargeable battery coming with original kit. Or replacement of regular type
AA battery clip (BC390) is also available in Temco’s variety of optional products. You can use world
