[. . . ] Available selections are ±1 MHz, ±2 MHz, ±5 MHz, ALL, PMS-X, and BAND. ALL: The scanner will sweep all frequencies between 108 - 520 MHz and 700 -999. 990 ALL MHz. PMS-X: PMS-X The scanner will sweep frequencies within the currently-selected PMS frequency pair (X is PMS memory channel number). X BAND: BAND The scanner will sweep frequencies only on the current band. The "P-XX indication will appear on the display if you P-XX" P-XX engage PMS scanning, while the "P SC indication will P SC" appear on the display when other scanning modes are engaged. If and when the scanner encounters a signal strong enough to open the squelch, the scanner will halt temporarily; the decimal point of the frequency display will blink during this "Pause" condition. The scanner will then resume according to the Scan-Resume mode selected in the previous section. To cancel scanning, press the [SCAN(SEL )] key momentarily again (or press the microphone's PTT key). 1) When you start scanning, the FT-7900R will be changing frequency in the upward direction. If you want to change direction of the scan while it is underway, rotate the DIAL knob one click in the opposite direction (in this case, one click counterclockwise). You'll see the scanner turn around and change frequency downward!2) Pressing and holding in the microphone's [UP] or [DWN] key will cause the scanner to sweep frequencies only on the current band. If you would like the scanner not to be restricted to the current band, you may change Menu #46 (VFO. BND) to allow the scanner to hop to the low edge of the next-highest band when the VFO frequency reaches the high end of the current band (or vice- versa). See page 77 for details.

SCANNING
MEMORY SCANNING
Memory scanning is similarly easy to initiate: 1. Set the radio to the Memory mode by pressing the [V/M(MW)] key, if necessary. As with VFO scanning, the scanner will halt on any signal encountered that is strong enough to open the squelch; it will then resume scanning according to the Scan-Resume mode set previously. To cancel scanning, press the [SCAN(SEL)] key again (or press the microphone's PTT key). You may initiate the memory channel scan by pressing and holding in the microphone's [UP] or [DWN] key.
How to Skip (Omit) a Channel During Memory Scan Operation
Some continuous-carrier stations like a Weather Broadcast station will seriously impede scanner operation if you are using the "Carrier Drop" Scan-Resume mode, as the incoming signal will not pause long enough for the transceiver to resume scanning. Such channels may be "Skipped" during scanning, if you like: 1. Set the radio to the Memory Mode by pressing the [V/M(MW)] key, if necessary. Rotate the DIAL knob to select the Memory Channel to be skipped during scanning. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode. [. . . ] Menu #42 [SQL. TYP] Function: Selects the Tone Encoder and/or Decoder mode. Available Values: OFF/ENC/ENCDEC/REV TN/DCS Default: OFF ENC: CTCSS Encoder ENC DEC: CTCSS Encoder/Decoder REV TN: Reverse CTCSS Decoder DCS: Digital Code Squelch Encoder/Decoder
