| ** Note ** Its best to do this mod before applying any power to the radio. |
| Channel Modification 1) Remove the back cover. 2) Locate the small circuit board that has the PTT, UP, Down, and Lamp buttons. 3) On the back side of the board, towards the bottom outside edge, you'll see 3 circuit pads that just end. 4) Solder a jumper across all 3 of these pads connecting them all together. 5) Put radio back together. You cannot increase the modulation or power on this radio. It doesn't have enough power to do so. If you already applied power, (battery Pack) you will have to reset the microproccessor on the radio. You will only have to do this once. 1) Remove the battery pack and clip a jumper across the battery termanals. 2) Turn on the power switch. 3) Let the radio sit 1-2 days with the radio switch in the ON position. 4) After 1-2 days, remove the jumper off the battery termenels, but do not turn the switch to the OFF position! 5) While the radio is still in the OFF position, press and hold down the CH9 button while sliding on the battery pack. Hold the button down for about 4 seconds. 6) Release the CH9 button. You now have 400 channels. You can press the CH9 button to change bands. You will need to hold down the CH9 button while turning on the radio to get the extra channels. If you don't, the radio will just operate normally. |
