The 0.0-9.9kHz range
is repeatedly searched
in
100Hz steps.
When the DS switch is ON in SSB/CW mode, the frequen-
cy is searched, that is, the digits for "kHz" and "100Hz"
are set to "00" and the 0.0 to 9.9kHz frequency range is
swept repeatedly at a speed of 60mS per step.
If a signal is present during search swept, tone will be
heard, allowing you to check the signal in SSB mode. It is
thus possible to locate stations quickly.
NOTE:
If the transmitters are keyed in this Mode, a momentary
tone will sound to remind you that the transceiver is in
search mode.
3.4 MEMORY SWITCH
Using this switch, commonly used frequencies (repeaters,
etc.) can be stored in the memory. Frequencies set by the
VFO are stored in channels 1 through 5 by using the M
switch. Stored frequencies can be called-up by placing the
MR switch ON.
Two different frequencies (transmit and receive can be
stored in channel 5, so the transceiver will operate on any
repeater split. The receiver frequency is stored in memory
just as for channels 1-4. To store the transmit frequency in
memory, set the transmit frequency in the receiver mode
and then press the M switch in the transmit mode. (See Fig.
3-3)
NOTE:
1. When a memory is vacant, the memory frequency is
144.0000MHz.
2. The memory frequency called-up by the MR switch is
displayed in 5 digits, regardless of mode.
3. To clear a frequency stored in memory, simply store a
new frequency in that memory.
4. If you desire to retain the memories, back-up power
should be supplied to the micro-computer
(1) A power cord should be connected directly to the
battery terminal.
(2) A back-up supply (Part No. W09-0008-05) should
be used.
In either case, back-up current of about 2.5mA is re-
quired.
5. If power is disconnected, the back-up function is retain-
ed for only 1-1.5 sec. If instantaneous voltage drop at
engine starting continues for more than 2 sec, the micro
computer will be reset and the memory cleared.
6. If you wish to retain the memories even when changing
the installation between the car and the fixed station,
utilize a back-up cord as shown in Fig. 3-4.
3.5 SCAN OPERATION
TR-9000 scan operation is classified into auto scan (signal
stops at a certain point and scan restarts when signal is ab-
sent) and free scan.
• Auto scan
Auto scan is available only in the FM mode.
1. Set the squelch control to the threshold point (noise
disappears at no-signal time and BUSY lamp goes off).
2. Next, press the SCAN button to start scan operation.
3. When a signal is present, scanning stops. When the
signal drops scan restarts automatically.
