HARDWARE INSTALLATION
Be certain to follow standard anti-static procedures when handling any of Midian’s products.
Radio Firmware: Midian recommends that the radio have the latest firmware version (R05.08.07 as of this
writing). However, the scrambler should work with firmware versions as low as R03.01.00, but this is not
recommended. If the radio has a firmware version older than R03.01.00, it
must be upgraded.
Verifying the firmware version can be done several ways. On most radios, this information is on a label on the
back of the radio. For keypad & 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. Remove the antenna, knobs, and battery.
2. With a Chassis Opener tool from Motorola or a 3/16” flat blade screwdriver, gently insert the tool into the
space between the case and the radio chassis at the bottom of the radio. Gently pull the tool downwards,
separating the bottom of the chassis from the case. Make certain the rubber seal does not get damaged.
3. Pull the bottom of the chassis downward until the knob switches are clear from the case. Flip the chassis
open so that the bottom of the case and the bottom of the chassis are end to end. Be careful when opening;
as there are flex cables installed.
4. Lift the latches on the main board to release the 40-pin flex cable and the Speaker’s 20-pin flex cable from
their connectors.
5. Remove the RF shield in the front cover. This is done by inserting a flat blade screwdriver or a scribe behind
the arm tab, pushing down, and then prying inwards. The tab should pop out. NOTE: Do not pry upwards
from underneath the arm as damage could occur to the keypad electronics or Midian’s scrambler if already
installed. After releasing all 4 arm tabs, gently lift the bottom of the RF shield and then pull downward to get
the 2 top tabs clear of the case.
Installing the Scrambler:
1. For radios without a keypad and display, there may be a plastic piece in the front cover that should be
removed, leave the rubber piece (if present) installed. For radios with a keypad and display, unlatch the flex
connectors from the keypad electronics, remove the flex cables, and remove the keypad electronics.
2. 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. Install the scrambler with the 40-pin connector towards the bottom facing up.
3. Reinstall the display flex and close the latch. Insert the other side of the 40-pin flex cable into the 40-pin flex
connector on the radio’s main board. Reinstall the speaker flex and close the latch.
