HARDWARE INSTALLATION
Be certain to follow standard anti-static procedures when handling any of Midian’s products.
Radio Firmware:
For the mobile radios listed, it is necessary to have radio firmware version R05.00.00 or higher.
If the radio has an older firmware version, it is necessary to upgrade to the newest firmware.
Verifying the firmware version can be done several ways. On most radios, this information is on a label on the
bottom of the radio. For display radios, selecting the SoftwareVer# option from the utility menu will report the
version. Consult Motorola if you cannot determine the firmware version.
Disassembling the Radio:
Additional disassembly instructions are also available in Motorola’s Basic Service Manual.
1. Disconnect
power.
2. Remove plastic cover from the radio chassis by prying the sides away and lifting up.
3. Remove the 6 retaining bolts from the metal lid using a Torx™ size 20 screwdriver. Carefully begin removing
the lid. If there is already an option board installed such as a voice storage board, disconnect it by gently
lifting the latch holding the 40-pin flex cable in place.
4. Remove the lid completely. Unscrew the three bolts holding the option board frame to the lid if one is present.
Note: It is not recommended to use the radio for transmitting while disassembled, as some model radios require
the lid to be installed for RF power.
Installing the Scrambler:
1. Insert the 40-pin flex cable into the 40-pin flex connector on the scrambler, making certain it is seated
properly, then close the latch. The silver foil side of the flex should face the edge of the board.
