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. If a feature is not available, please contact Midian to see if the feature can be added.
Known Issues:
Tones:
Tones such as the Go-Ahead Beep, programming tones, etc. are not heard on this radio.
Multi-Code:
If using multiple codes in the TVS-2-TAIT or VPU-15-TAIT and other Midian TVS-2 or VPU-15 Series
scramblers are being used in other types of radios, it should be noted that in the TVS-2-TAIT and VPU-15-TAIT
the binary is reversed. This means that code 4 in the TVS-2-TAIT or VPU-15-TAIT would equate to code 1 in a
regular TVS-2 or VPU-15 scrambler.
