Waring:
You must have a proper license to operate on the MARS/CAP frequencies. Alinco declines responsibilities for the use of modified equipment out of ham bands. The warranty is void when the modification is done. The declared specs are not applicable out of the ham bands. DR-135T operates in the narrow FM mode TX/RX but the unit is not officially new CAP requirements compliant.
Modification:
Turn the radio off. Disconnect the power source. Open the bottom cover by removing the 4 screws located on each corner of the bottom cover surfce. Locate a BLUE looped jumper wire that comes out of a slot on the back of the front control unit (it is attached to the back of the front panel on a pad labeled JP3). Remove the jumper and trim the remaining wire properly to prevent a short circuit.
Reassemble the bottom cover. Connect the power source and turn on the unit with the FUNC key pressed to reset the microprocessor. Settings will become the factory default.
The unit will transmit and receive between approximately 140 and 170 MHz where the VCO will lock. If the display is flashing, you have lost VCO lock and operation is not possible. Alinco does not guarantee any operations outside of the amateur bands.
