V.A.D.E.R.
VOICE-ACTIVATED DIGITALLY ENHANCED RADIO
PROFESSIONAL SECURE RADIO SYSTEM
USER’S MANUAL
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 (100mW) and HI
(1W) 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 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 V.A.D.E.R. radio under any
weather conditions in outdoors.
The V.A.D.E.R. secure radio system is the most suitable equipment for professional tasks requiring high security
and confidentiality.

FUNCTIONING METHOD OF V.A.D.E.R. SR21 RADIO
The SR21 radio has multiple programmable functions such as Simplex, Semi-Duplex, Channel Hopping,
Scrambling, setting of Priority Channel, setting of ID code (code squelch), time-out-timer, etc. by using optional
programming software. Refer the details on separate Programming Manual.
For your communication security
When the Channel Hopping function is set on the SR21 radio, the Tx (Transmit) frequency on each time of
pressing the PTT button (or triggering the PTT by VOX) is randomly selected within pre-set 10 frequencies and
sends the ID code on FSK signal. The other radios in the same Group# search the FSK signal in 10 frequencies
by high speed scanning all the time while the radios are in stand-by mode, and lock on one of the frequency
when the ID Code coincides, and start to engage in the Rx (Receive) mode. By applying this function, the
communication frequency changes on each Tx/Rx session, so that it is hardly traceable by the third party to
prevent from undesired monitoring. Furthermore, in combination with the Scrambling transmission (Frequency
Conversion), a degree of communication security comes up to the highest level.
1. The SR21 radio has programmable frequencies in 1-16 Groups. Each Group #1 to #15 has max. 11 channels
where appropriate frequencies can be programmed. When the radio is to be programmed for use in
Semi-Duplex operation, the Tx frequency is set on channel #0 and the Rx frequency is set on channel #1.
When the radio is programmed for use in Simplex operation with Channel Hopping function, the same
frequency is to be set on both cannel #0 and channel #1, and appropriate frequencies are to be set on other 9
channels within the bandwidth preferred. In Group #16 (in other words, position #16 at the Group Selector
Switch), the Emergency signal alerting frequency is to be programmed. The frequency for Priority channel can
also be set in this Group #16.
2. When the radio is powered ON by turning the Power/Volume Switch to clockwise, and when the Hopping
command is programmed “1”, 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. When the Hopping command is programmed “0”, the radio receives the carrier wave on
the frequency set on the channel #1. When any frequency programmed on Group #16 for Emergency alerting
signal or for Priority channel, the radio also receive the carrier wave on this frequency.
3. When the carrier wave is detected on one of the destined frequencies, the radio immediately stops scanning to
recognize the ID code and compares it with the radio’s preset ID. If the ID in the received carrier 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 ID does not coincide with the radio’s preset ID, then the radio keeps on
scanning the destined frequencies in the Group. Though the Hopping command is programmed “0”, means that
the Channel Hopping function is not in use, the squelch can be opened only when the ID is recognized as
coincident to the pre-set ID.
Caution: If the ID is programmed “000”, the squelch can be opened for any carrier wave that the radio receives.
When the Hopping command is programmed “1”, means that the Channel Hopping function is in use, the ID must
be set other than “000”, otherwise the frequency scanning cannot work.
4. Monitor/Emergency button provides either of the following function.
Monitor ….. Short pressing of Monitor/Emergency button
By short pressing of Monitor/Emergency button (less than 2 seconds), the radio opens the squelch and
receives the carrier waves in transmission on the channel where the scanning stops. This is to be used for
checking whether the channel is open or in use.
Emergency ….. Long pressing of Monitor/Emergency button
By prolong pressing of Monitor/Emergency button (more than 2 seconds), the radio keeps on transmitting
the Emergency alerting signal until the Power Switch is turned OFF. The Emergency alerting signal can
be selected from 10 types of tones and duration/interval is also programmable.
Important: While the Emergency alerting signal is being transmitted, the Mic line of SR21 radio is also
in active, so that you can override your message over the alerting tone for letting a Group member know
of your location and emergency message. For facilitating this function, it is important that the duration of
alerting tone transmission should be programmed to hold sufficient time for enabling to transmit the
massage at the same time. While any one of the SR21 radio in a Group is transmitting the Emergency
alerting signal, all other radios in the same Group coinciding the ID are kept on capturing the signal (and
message), and are unable to communicate with others. For not blocking the Group’s communication, it is
important that the interval of Emergency alerting signal should be programmed to hold sufficient time for
enabling other radios in a Group to maintain the communication for the rescue order in the interval of
Emergency alerting tone. The default setting of signal interval is 5 seconds.
5. When PTT Button is pressed, or when the radio PTT is triggered by VOX, channel scanning is immediately
stopped and searches the existence of any carrier wave in that frequency in air. If no carrier wave is detected in
that frequency, the radio is engaged in Tx status and starts to transmit its Group’s ID code. When the Tx status
is engaged, the operator can hear a short “Pip!” tone via his speaker of Headgear or Ear Mic for letting him
know that his transmission becomes established. If the existing carrier wave from other transmission is
detected in that frequency, no Ready-to-Tx tone as “Pip!” is heard, and Tx status cannot be engaged. In this
case, release the PTT Button for making the radio restart to scan the channels, and press the PTT Button once
again, or make voiced sound again after 0.7 second in VOX mode, to catch the “open” channel.
Remarks: If the Hopping command is programmed “0”, the Tx frequency is fixed, as it is pre-set on Channel #1.
Remarks: Engaging the Tx status by neglecting the existence of other carrier wave in air can be programmed.
6. 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 the operator can start to transmit speech message in air. Virtually, the time required for
sending the ID is very small, so that the operator can start to speak right after hearing of Ready-to-Tx tone via
his Headgear or Ear Mic.
7. When PTT Button is released, or when the radio is turned to Receive/Stand-by status by no detection of voiced
sounds to trigger the VOX, the Mic line is to be OFF and send the End-of-Transmit signal for indicating to
terminate transmission. When the Tx status is disengaged, the operator can hear a short “Pip! Pip!” tone via a
speaker of Headgear or Ear Mic for letting him know that his transmission is now terminated, and the radio
returns to scan the channels for receiving.
Remarks: If the Hopping command is programmed “0”, the radio returns to the Channel #1for Receive/Stand-by
status after sending the End-of-Transmit signal.
Caution: If the Tx status keeps on engaging for more than 30 seconds*, the transmission is automatically shut off
and the radio returns to scan the channels for receiving, or returns to Channel #1 when the Hopping command is
programmed “0”. (*programmable factor)
8. On the radios that have been receiving the message, the channel scanning is restarted when they receive the
End-of-Transmit signal. If the radio(s) can not, or failed to, receive the End-of-Transmit signal, the channel
scanning starts after 2.5 seconds* from the end of carrier wave being tuned in. (*programmable factor)
9. When the Group #16 is selected by Group Selector Switch, and when either the frequency for Emergency
alerting signal or Priority channel is programmed, the radio can be used as a conventional two-way transceiver
by simple PTT or VOX operation on this channel. This function can be used for All Call of all radios in a
Group.
10. To deactivate particular Group(s) for Tx/Rx can be programmed though the frequencies are programmed on
all Groups’ channels. When the Group Selector Switch selects the inactive Group #, the operator hears alerting
signal as “Boop, Boop” signaling the user that the Group selected is out of order.
11. When the battery runs low (voltage detection), the operator can hear short alerting tone such as “Pu!, Pu!” for
signaling the user of low battery life. When this tone is heard, replace the battery immediately.
Remarks: This Low Battery alerting tone can be heard only in the Transmit status and may be resumed in the
Receive/Stand-by status. This is due to high current consumption required for transmission. In any status when the
Low Battery alerting tone is heard, it is requested to replace the battery.
SET-UP
1. Hand tighten the Antenna by turning it clockwise on to the Antenna Connector on the top panel of radio.
Caution: There are 3 types of Antenna depending on the frequency bandwidth programmed on the SR21 radio.
#1:AT20A-01 for 150-158MHz
#2:AT20A-02 for 158-166MHz
#3:AT20A-03 for 166-174MHz
Be sure to use the right Antenna for optimizing the performance. Use of wrong Antenna will make insufficient
coverage of communication area, and may cause malfunction of radio due to excessive load put on the transmitter.
2. Mate the key guide of audio connector of Headgear or 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 (turn counterclockwise) and take 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 Remote PTT Switch and press
in. Turn the Lock Screw clockwise until it is firmly tightened.
Caution: 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 the waterproofing.
4. Put the Headgear or Ear Mic in the on position.
Caution: Make a good contact of the Microphone and Speakers of the 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 ear tip 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 Ear Mic to your
ear may cause insufficient audio performance as like deterioration of microphone sensitivity or lack of
intelligibility in transmit audio.
Caution: Ear Mic is NOT waterproof. DO NOT use in the water or under heavy rain or splash of water.
