The set of dip switches on the right under the little cover marked "quite" is used to program the radios uhf frequency and also used to set the ctcss frequency.
I have the owners manual and it makes no mention of the left hand set of dip switches or the set button in the middle. You have to remove the entire plastic cover to expose all the hidden switches. It is not mentioned in the service manual on how to program this either, but it does say the radio CAN be programmed to any frequency from 461 to 469 mhz. Also the owners manual states if taken to a "authorized facility", it says that it can be set to other frequencies than the 8 listed in the owners manual.
There is a way to do this but who has the secret programming info on how to do it other than the mentioned "authorized facility"
Any help out there??
