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.

Midian recommends the following values based on 60% modulation: The following table shows Midian’s recommended levels in mVpp for the VS-1200, VS-110 & VS-1100 at 60% modulation for tested models of radios:...
HARDWARE INSTALLATION Be certain to follow standard anti-static procedures when handling any of Midian’s products. When ordering the scrambler, the radio must be specified as audio levels vary between radio models. TK-2180, TK-3180: Plug the unit into the options connector located behind the options door under the battery. Before plugging the unit in, remove R-659 to open the radio’s TX path and R-670 to open the radio’s RX path.
RADIO PROGRAMMING TK-2180, TK-3180: Use KPG-89 version 1.51 or higher. Under the “Edit” menu select “Extended Function” and set “Optional Board” as “Voice Scrambler”. Under the “Edit” menu select “Key Assignment” and set “Side 2” under the “Top/Side” tab as “Scrambler”. This will set the button under the PTT as the mode select button.

TK-5710: Under the “Edit” menu select “Extended Function” and set “Optional Board” as “Voice Scrambler + ANI Board”. Under the “Edit” menu select “Key Assignment” and under the “Head 1” tab set the desired button (PF1-PF5) as “Scrambler/Encryption”. This will set the programmed button as the mode select button. If Emergency ANI in the VS-1200 or VS-1050 is being used PF5 must be set to “Emergency”.

Under the “Edit” menu select “Key Assignment” and under the “Panel” tab set the desired button Triangle, A, B, C or Square as “Scrambler”. This will set the programmed button as the mode select button. If using Midian’s Kryptic ENI set the triangle button to Emergency.
However, some features may not be available in the radio when an option board is used. If a feature is not available, please contact Midian to see if the feature can be added.
