1. Remove power from the radio. 2. Remove the covers and locate the TMP87PP21DF Microprocessor( see Picture ) near the front right of the unit. 3. Locate and Remove the surface mount Resistor R138 to the left side of the Microprocessor this will let the radio TX on all the channels but the ?????? Government Frequency?????? range which is Listen Only!. 4. Resistor R619 controls the TX on the ??????Government Frequency?????? range and is not installed from the factory. Install the resistor that you removed from R138 to the R619 pads. (1k) to activate the ?????? Government Frequency?????? range. 5. Power from the radio by disconnecting the Power leads for 15 seconds to reset the Microprocessor.
