VADER
VOICE—ACTIVATED DIGITALLY ENHANCED RADIO
PROFESSIONAL SECURE RADIO SYSTEM
USER’S MANUAL
ABOUT THE VADER SYSTEM
The VADER 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 VADER radio features a
scrambling transmission along with a high-speed frequency
scanning that makes group's communication hard to he
intercepted
The RF output power is selectable between LO (IOmW) and HI
(lOOmW) according to the group's range of activities. Minimizing
the RF output power prevents detection from outside of the group.
The VADER radio does not come with a built-in microphone or a
speaker, You can use this radio by connecting the external audio
device elflter a Headgear or on Bar Microphone both applies
Temco's hone conduction technology
Neither the Headgear nor the Bar Mic prevents you from wearing
a helmet. Furthermore, neither device sets its microphone near
your mouth. The system's complete facevfree configuration assists
your active tasks.
A remarkable feature of the VADER 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 tin
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 ftmction 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
performance
The Radio Housing is made from magnesium 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 fill size AA dry batteries or same-sized rechargeable cells into the pack,
Both the radio transceiver and the battery pack are submersible. You can use the VADER radio under any weather
conditions in outdoors
The VADER secure radio system is the most suitable equipment for professional tasks requiring high security and
confidentiality.

FUNCTIONlNG METHOD OF VADER RADIO
1. The VADER radio has programmable frequencies in 1716 Groups. Each Group from til—ttli has max. 10
channels where appropriate frequencies are to be programmed. In Group #16 (in other words, position #16 at
the Group Selector Switch), the Emergency signal alerting frequency is to be programmed. This frequency is
also used for transmitting the Homing signal.
2, When the radio is powered by turning the PowerNolume Switch to clockwise, an immediate scanning of each
channel (max, of 10) within the Group being selected by the Group Selector Switch is commenced to search
any transmission of carrier wave on the destined frequencies.
3. When the carrier wave on the destined frequency is received, the radio recognizes the ID signal and compares
it with the radio’s preset ID. If the ID in the received cam'er wave coincides with the preset ID of the radio,
squelch is opened and the radio is engaged in the Receive mode. If no ID is detected, or if the detected l'D does
not coincide with the radio’s preset ID, then the radio keeps on scanning the channels in the Group,
4. When PTT Button is pressed, or when the radio is turned to Transmit mode by VOX, channel scanning is
immediately stopped and searches the existence of any carrier wave in that £requency in air. If the radio detects
the carrier wave from other transmission in that channel, no Transmit mode is engaged, In this case, release the
FIT Button and make the radio restart to scan the channels, and press the FIT Button once again to catch the
“open” channel. If no carrier wave is detected, the radio is engaged in Transmit mode and starts to transmit its
1D signal. When the Transmit mode is engaged. you can hear a short “Pip!" tone via a speaker of Headgear or
Ear Mic for letting you know that your transmission becomes ready,
5. When sending the ID is completed, the Mic line to process the audio signals from Headgear or Ear Mic is
turned to be ON. and you can start to transmit your message in air. Virtually, the time required for sending the
1D is very small, so that you can start to speak right after your hearing of Transmit indication signal via your
Headgear or Ear Mic.
6, When PIT Button is released, or when the radio is turned to Receive/Standby mode by no detection of voiced
sounds to trigger the VOX circuitry, the Mic line is to be OFF and send the End-of—Transmit signal for
indicating to terminate transmission. When the Transmit mode is disengaged, you can hear a short “Pip! Pip!”
tone via a speaker of Headgear or Ear Mic for letting you know that your transmission is now terminated, and
the radio returns to scan the channels.
Remarks: If the Transmit mode keeps on engaging for more than an sgonds". the transmission is automatically
shut oif and the radio returns to scan the channels. (* adjustable factor)
7r On the radios that have been receiving the message, the channel scanning is restarted when they receive the
End—of-Transrnit signal, If the radio(s) can not, or failed to, receive the EndvofvTransmit signal, the channel
seaming starts after 2.1mm from the end of carrier wave being tuned in. (* adjustable factor)
8. When the Group Selector Switch is set at 1816, the Emergency and Homing signal is able to transmit. The
programmed frequency for Emergency and Homing transmission at #16 of each radio is automatically
monitored by the other radios in each Group, and is received when the preset ID coincides.
Emergency : Press and hold on the FIT Button. The Emergency signal (Peep! Peep!) is transmitted while the
FIT Button is depressed. During the Emergency Transmit, the carrier wave is continuously transmitted and the
Mic line is kept engaged. so that the voice message can also be transmitted with the Emergency signal. The
preset interval of Emergency signalis 5 scsgndfi (* adjustable factor)
-'
havlng coinciding ID keep on receiving and are not able to transmit. Be sure not to continuously transmit
the Emergency signal. It is recommended to transmit the Emergency signal intermittently, so that the other
radios are able to transmit rescue order in the interval of Emergency signal.
While the Emergency signal is being transmitted from one radio in the Group, other radios
Homing : Press the Homing Button. The Hunting signal (Pip! Pip!) is automatically transmitted after the
Homing Button is released until the Group Selector Switch is changed to set other than $016 or the radio is
powered off. The carrier wave is intermittently transmitted in tune of the Homing signal for saving battery. The
preset interval of Homing signal is Mr (* adjustable factor)
Remarks: Though the Homing signal is being automatically generated. its carrier wave is intermittently
transmitted in tune of the Homing signal, so that the other radios are able to transmit in its interval of 10 seconds*.
SET-UP
1. Hands tighten the Antenna by turning it clockwise on to the Antenna Connector on the top panel of radio.
2. Mate the key guide of audio connector of Headgear 01 Ear Mic with the AF Connector (6 pin) on the top panel
of radio and press in. Turn the Lock Screw clockwise until it is firmly tightened.
3. if required, unscrew and mke off the water-sealed cap on the Program Connector (7 pin) on the top panel of
radio, and mate the key guide of the audio connector of RemoteP'l'l' Switch and press in. Turn the Lock Screw
clockwise until it is firmly tightened.
@. Be sure to securely tighten the Antenna and all other audio connectors on right position
Insufficient tightening of Antenna and connectors may cause improper performance of waterproof.
4. Put the Headgear or Ear Mic on position.
@: Remember to steadily contact the Microphone and Speakers of Headgear to your head. Loose
contact may cause insufficient audio performance as like deterioration of microphone sensitivity or low
audio volume from the speakers.
When Ear Mic is used, remember to select the earth) either Medium or Large for your comfortable fit to
your ear, and insert the earpiece as deep as possible into your ear canal. Loose contact of Bar Mic to your
ear may cause insulticient audio performance as like deterioration of microphone sens'tivity or lack of
lntelligfltility in transmit audio.
EEutton: Ear Mic is NOT waterproof. DO NOT use in the water or under heavy rain or splash of water.
