AOR AR2700 Operating Manual page 16

For example 133.7 MHz [1] [3] [3] [MHz] [7] [ENT] there is no need to add
trailing zeros. Frequencies below 1 MHz may be preceded by [0] [MHz]
frequency then [ENT].
The [UP] key may be used to force the receiver to continue search / scan from
a busy channel and to reverse the direction of search / scan should the
receiver be tracking downward. The key will also act as an upward tuning
control just like DIAL.
The key is also used to select menu options under certain circumstances.
The key may be used to place the receiver in manual search mode by pressing
and holding the [UP] key for more than 1.5 seconds while in manual mode.
The key sequence [2ndF] [UP] places the receiver in ready condition to
CLONE data to another AR2700 connected to an optional CU8232 via the
optional IF-ADP. This facility enables an exact data copy of one receiver to be
made with another possibly belonging to a friend etc. The display "COPy
SEnd" and a flashing legend "SERIAL" indicates operation.
Use the UP / DOWN keys or [DIAL] to toggle between SEND and RECEIVE
modes, press [ENT] to accept the selection, always select the receive unit first.
The first segment of the signal bar graph will appear to confirm operation,
as the data transfer progresses so the bar graph will grow to indicate that
the process is functioning correctly. It will take a few minutes to transfer
all the data.
The sequence [2ndF] [UP] with the UP key being held for more than 1.5
seconds places the receiver into the menu to select the RS232 parameters for
connection to a computer via the optional IF-ADP and CU8232 adaptor and
interface units.
The [DIAL] is used to select the baud rate between 9600, 4800 and 2400 bps
and the UP / DOWN keys select the addition of LF (line feed).
[DOWN] / kHz / SS - key
The [DOWN] key is used as a kHz key during frequency entry and
provides an alternative method of frequency entry to the MHz (decimal)
key method.
For example, a frequency of 945 kHz may be entered as [0] [MHz] [9] [4] [5]
[ENT] or [9] [4] [5] [kHz] [ENT] the later taking one less key press.
This kHz method of entry makes entry from short wave frequency listings
particularly easy. A listing of 6045 kHz (6.045 MHz) may be entered as
[6] [0] [4] [5] [kHz] [ENT]
The [DOWN] key may be used to force the receiver to continue search / scan
from a busy channel and to reverse the direction of search / scan should the
receiver be tracking upward. The key will also act as an downward tuning
control just like DIAL.
