In 12.5 kHz .or 25kHz step size. direct frequencyselection will be completed in the 10kHz digit. Whenyou enter the fo llowing keys for the 1 0k Hz digit. 1 kHzand 10 0 Hz digit frequencies are automatical ly selectedthe list below.(10 kHz dIgit) Frequency (10 kHz d,git) Frequencykey .

Press the F key momentarily. then press theM Hz/STEP key. The current frequency step size wi llbe displayed.( F )STEP(MHZ) I!IAPO2. Rotate the Tuning control until the desired tuning stepsize appears in the display. The frequency step isindicated in the chart below.16S±> 10 ±> 1S ±> 20 ±> 1 2. S±> 2S ±> S3. To complete the programming of the step size you canpress the M Hz/STEP key.The chart below illustrates the way the displayed frequency will changewhen you change from one step size to another.51015201012525 12525t05101520, , ,0,5,10,15 0 0 020,25.30,35 25 12.5 1040,45,50,55 50 25 2060,65,70,75 7580,85,90,9537.5 3050 5062.5 6075 7087.5 80For example:Assume you are presently displaying a frequency of 439.920 MHz andhad previously selected a 20 kHz step size. If you were to change thestep size to 12.5 kHz the display would then read 439 . 925 MHz.4 -2-4. Pr ogrammable VFO Tuning Lim itsThe radio provide the capability of programming the VFOtuning range. in 1 MHz band segments. as well aproviding a separate programmable band scan function.(See section 4-5.) For example you could tell the trans-ceiver that you only wish to tune the 144.000 MHz and
