GENERAL INFORMATION

Midian’s SVR-1 is a simplex repeater maker that can be installed into a portable radio. The SVR-1 detects COR
or VOX from an incoming transmission and records the incoming audio (up to 3 minutes). When the COR or VOX
is no longer detected the SVR-1 keys the radio and retransmits the recorded audio. The SVR-1 enables users to
expand radio coverage into poor coverage areas.

PRODUCT PROGRAMMING

The SVR series are programmed using Midian’s KL-4F and the MPS software

Go to our website midians.com and under downloads> software download the latest MPS software version. If
using the supplied CD-ROM insert it into the PC’s CD-ROM drive. In the browser that will pop-up, install the MPS
programming software. Be certain that the “Install KL-4 USB Driver” box is checked during the installation
process.

Open Windows’ Control Panel and go to Device Manager.

Open Ports (COM& LPT) to identify the port assignment issued by computer. Plug in the KL4 programmer to the
USB port and the screen will flash and show the device location.

Open the software and choose product from product tree then set appropriate comport selection in the MPS
software as needed

After entering the parameters, save the file by going to File - Save As. Enter the file name in the File Name block
and click Save. Saving the file will allow for quick and easy reprogramming of units.

KL-4 Programming: The Yellow and Green KL-4 leads need to be connected to the unit for programming.
Connect the green KL-4 lead to the program in hole (see below), connect the yellow KL-4 lead to the program out
hole (see below) on the unit. The black lead does not need to be connected when using the KL-4. Plug the board
onto the KL-4 p-7 KW2 connector. Push and hold the power button on the KL-4 and wait three seconds, then
click “Program Unit” in the KL-3 software.

KL-4 Reading: The Yellow and Green KL-4 leads need to be connected to the unit for reading. Connect the
green KL-4 lead to the program in hole (see below), connect the yellow KL-4 lead to the program out hole (see
below) on the unit. The black lead does not need to be connected when using the KL-4. Plug the board onto the
KL-4. Push and hold the power button on the KL-4 and wait three seconds, then click “Read Unit” in the KL-3
software.

Store on COR/Store on VOX: Select the appropriate method that the unit should use to start recording incoming
audio.

COR Hold-Up Time This sets the amount of times after a loss of COR or VOX that the unit will wait until it
retransmits the recorded audio.

VOX Settings > Sensitivity: This is a threshold detection based on the energy level in the audio.

VOX Settings > Attack Time: This sets the minimum time before the unit will detect VOX based on the sensitivity

setting.

VOX Settings > Decay Time: This sets the time before the unit will drop the VOX detection. Be certain to set this
long enough so that you do not have drop outs between words or on brief pauses.

Beep Options > Power Up: Enables a short beep sequence that takes place immediately after power-up.

Beep Options > Error: This beep may be triggered by any input event if programmed to do so. For example, if a

long press on the Mode Input is not assigned to a function, it may be configured to generate the error beep.

Beep Options > Mode: Not used as the radio offers its own mode tones for the option board enable.

Beep Options > Go Ahead: Not currently used.

Beep Options > Wake Up Beep: Enables a short beep to be sent over the air immediately after PTT is pressed.

Enabling this beep is recommended when the 'Wake on VOX' feature is used. This may also be used to get the
attention of the party receiving a call.

Beep Options > Courtesy Beep: If selected, once the unit is done retransmitting the recorded audio it will
generate a courtesy tone to let others know it is done retransmitting.

Voice Compression: If checked the SVR-1 can store up to a 3-minute voice message. If unchecked the SVR-1
can store up to a 2.25 minute voice message, but with a higher level of audio quality.

Power Up In Store/Retransmit Mode: If selected the unit will power up in repeat mode. This box must be
selected if doing repeat enable on a per-channel basis.

Key-Up Delay: This sets the amount of time the unit waits after keying the base station radio before it starts to
retransmit the recorded audio.

Trunking Delay Enable: Check this box if using a trunking system. This will cause the unit to hold off
regenerating the recorded audio until it has received a channel acquisition acknowledgement from the base
station radio.

Common PTT: Check this box if PTT In and Out are connected to the same point.

PTT Cancels Store/Retransmit: If checked and the PTT is pressed during store/retransmit the unit will not

retransmit the incoming transmission.

Number of Retransmits: This sets how many times the unit will retransmit the last recorded audio clip.

Retransmit Interval: This sets the time interval between the retransmits set in the Number of Retransmits field.
