Page 115) The transceiver actually changes frequency only after the 1 kHz digit is entered. The 1 kHz digit is notdisplayed if it is a zero.If you do not enter the 1 kHz digit, the 1 kHz indicator flashes and the transceiver defaults to the previousoperating frequency.Notes1 If the frequency step of the UHF band is 10 or 20 kHz, the 1 kHz digit becomes zeroautomatically when you enter the 10 kHz digit.2 If you press an invalid key, the valid value nearest to that number is entered.3 If you do not press a key within 10 seconds, the normal frequency display returns.4 If you press the VFO key during input, the digits showing - return to the values that appearedbefore the direct entry mode was selected.If the frequency step is 12.5 or 25 kHz, the input ends with the 10 kHzdigit. The 10 kHz keys and frequencies set with the keys are listedbelow.Key Frequency Key Frequency0 00 5 501 12.5 6 62.52 25 7 753 37.5 8 87.54 37.5 9 87.5Using the Tuning ControlThe tuning control selects frequencies in up or down sequentially.Rotate the tuning control clockwise or counterclockwise to select the desired operating frequency.4 Step Size SelectionThe transceiver must be in the VFO mode to select frequency steps.To select the desired tuning or scan step size use the following procedure:1) Press the F key for longer than one second then press the 3 key. The current frequency step size will bedisplayed.2) Rotate the Tuning control until the desired tuning step size appears in the display. The frequency step isindicated in the chart below.VHF BAND 5!10!15!20!12.5!25!5
