3. Install the scrambler into the radio per the Hardware Installation Section of this manual. 4. Program the radio per the Radio Programming Section of this manual. *** Midian is not responsible for any damage/loss resulting from the use of Midian’s products.
VS-110: Midian’s VS-110 is a rolling double inversion scrambler that offers 1020 possible codes (4 groups with 255 codes per group). Of these codes the scrambler may be programmed with up to 4 of these codes. The VS-110 series is compatible with Icom’s UT-110.
English keyboard such as 0-9, A-Z (upper and lower case), *, #, @, $, etc. Spaces are also allowed. Midian does not recommend using international language character such as ñ, ä, ß, ü, é, etc. as these have not been tested.
The scrambler uses programmable gain amplifiers to accomplish this. Determining the gain settings for these amplifiers is an involved process, so Midian simplified this process by developing an algorithm that requires the technician to make only four voltage measurements. From these four measurements, all of the many internal settings are determined.

Adjust the slider bar such that the value appearing in the appropriate column matches what was measured as closely as possible. The following table shows Midian’s recommended levels for the VS-1200/VS-1100/VS-110 at 60% modulation:...
HARDWARE INSTALLATION Be certain to follow standard anti-static procedures when handling any of Midian’s products. VX-350: Remove the battery, exposing the option board cover and remove the cover. Plug the scrambler onto the options connector. Replace the option board cover and battery. The scrambler requires this radio have firmware version 1.0 or higher.

VX-4000, VX-5500 & VX-6000: Remove the cover of the radio exposing the options connector. Plug the FIF-7A (from Vertex) onto the options connector per Vertex’s instructions. Then plug the scrambler onto the FIF-7A. Replace the cover of the radio. The scrambler requires firmware version 2.02 or higher in the VX-4000. The VX-5500 has been tested with firmware version 0324.
RADIO PROGRAMMING VX-350: For the VX-350 radio programming software CE-86 v1.01 or higher must be used. Read the radio with the option board installed. Select “Common” from the menu and then “Option”. The “Option Unit” should be read as “FVP-35”. Under the “Common”...

VX-800: For the VX-800 radio programming software CE-31 v1.20 or higher (DOS) or v1.05 (Windows) must be used. Read the radio with the option board installed. Select “Common” from the menu and then “Miscellaneous”. Set the “Encryption Type” to “Hi Level”. This will also change the “Encryption Device” setting under “Common” > “Option”...

VX-4500 & VX-4600: For the VX-4500 & VX-4600 radio programming software CE-115 v1.01 or higher must be used. Read the radio with the option board installed. Select “Common” from the menu and then “Option”. The “Option Unit” should be read as “FVP-35”. Under the “Common”...
OPERATION Scrambler Operation: Mode Select: Press the radio key that was assigned in the radio programming. A tone followed by a higher tone indicates the unit was toggled into scramble mode. A tone followed by a lower tone indicates the unit was toggled into clear mode.
TECHNICAL NOTES Radio Compatibility: Midian has taken the utmost care to ensure the option board integrates into the radio with minimal impact to the features of the radio. However, some features may not be available in the radio when an option board is used.
