1. Remove the dettacheble front from the tranceiver.

2. Remove the bottom case. (4 srews in each corner).

3. Put the tranceiver in front of you, upside down,  with the antenna connecter pointed at you.

4. Locate in the upper right corner on the small  vertical placed print (witch is located behind the display adaptor) a group of 4 small 0 Ohm
   resistors in smd format, numbered 0-1-2-3.

5. Remove or lift resistor 0 for extended RX

   RX band 1 = 118-136 Mhz AM
   RX band 2 = 136-174 Mhz FM
   RX band 3 = 300-400 Mhz FM
   RX band 4 = 400-520 Mhz FM
   RX band 5 = 800-999 Mhz FM

6. Remove or lift resistor 3 for extended TX

   TX band 2 = 136-174 Mhz FM
   TX band 4 = 400-520 Mhz FM

   Note: When these two resistors are removed or lifted,  in the MENU there will be een extra menu-choice  (number 0) to switch between
            AM and FM on all 5 bands (AM only receive).
