mode, channel step, and attenuator information.

condition ready for data entry. The display legend “MANUAL” appears toward

receiver is in, press the [MANU] key.
Manual mode is used for frequency entry, change of mode, general listening
and memory write (data entry - into memory channels and program search
banks).
The key sequence [2ndF] [MANU] (with the [MANU] key held for more than
1.5 seconds) places the receiver into MANUAL SEARCH MODE with the
legend “SEARCH MANUAL” appearing on the top line of the LCD. The
receiver will search upward or downward from the currently displayed
frequency in whatever mode and channel step selected. The UP / DOWN keys
or [DIAL] may be used to reverse the direction of manual search.
The receiver will stop on active channels and the UP / DOWN keys or [DIAL]
may be used to force the process to continue passed the busy frequency. To
cancel manual search and monitor the currently displayed frequency press the
[MANU] key. (Holding the UP or DOWN keys for more than 1.5 seconds also
places the receiver into manual search mode.
