This field should not be enabled unless deemed necessary. Procedures to enter factory override information in the Factory Overrides menu should only be attempted by Qualified Service Personnel. Failure to perform procedures properly may seriously degrade the radio and/or system performance.

 

6.25 kHz step size for the 800 MHz frequency band:

Starting with Release R09.01.00, the CPS allows a 6.25 kHz step size for Conventional frequencies in the 800 MHz frequency band, to meet regulatory compliance in certain (non-FCC) countries; however, be aware that two radios operating on adjacent channels separated by 6.25 kHz only may experience an undesirable crosstalk phenomena.
