By remove the cover, you see a blue wire. Cut this wire and reset your TRX (PWR-on + FUNC).

Now you get the following frq. range:

VHF range:
76-108 mhz wfm only RX
108-136 mhz AM only RX
136-174 mhz FM RX and TX

UHF range:
400-480 Mhz FM RX and TX
800-999 Mhz FM RX
334-400 Mhz FM RX

To switch between bands use F and the CALL keys.
You can RX also on every band in AM by holding the F and pressing the LOCK keys.

Showoff display:
Use pwr onn together with V/M button, stop it by pwr on/off

• Set all nessesary data like: Frequency, Power, Shift...
• Then Push Powerbutton "OFF" - Hold the Band-Button and Power "ON"
  
  The Display shows "*R" above SubbandFrequency and no Buttons works only Power

To deactivate Hold Bandbutton and Power "on"

You can also set Repeaterfrequency with shift but not the same Band VV/UU and no High Powersetting because the Receiver is mutet.

1. Open the cover of the main unit and locate the CPU just behind the left side corner.
   
    
2. Locate a jumper wire marked JP3 on the circuit board near the CPU.
   
   
   
    
3. Cut the jumper wire, remove it and reassemble the radio.
   
    
4. Reset CPU by holding in the F key while powering the radio on.

After the mod, RX frequency expands to:
MAIN: 76-108MHz (WFM), 108-136 MHz (AM/FM), 136-174 MHz (AM/FM), 400-480 MHz (FM), 800-1000 MHz (FM), 335-400 MHz (FM)
SUB: 136-174 MHz (FM), 400-480 MHz (FM), 335-400 MHz (FM)

(T version is opened for RX already as default with 800 MHz cell frequencies blocked)

The TX frequencies should now be 140-150 MHz / 415-455 MHz MAIN BAND ONLY

The radio MAY actually TX over a wider range, but Alinco states that you risk damaging the unit.

NOTE: There is no cross-band repeat function in this unit; Alinco suggests that those requiring this function purchase the DR605.
