2. To search or seek (Up or Down) a station
After frequency is entered, depress UP or DOWN seek button to start search. Squelch control must be adjusted to just
above noise level to activate search. Channels M1 through M16 can be searched by depressing individual channel buttons and
then the UP or DOWN seek button accordingly. Frequencies will be searched in increments or decrements of 5 KHz or
12.5 KHz according to bands.
If exact frequency desired is unknown, enter a frequency a few KHz lower to begin search. For example, if the frequency
desired is approximately 470.015, start the search frequency at 469.000 or lower.

B) If you want to enter a frequency which you have already known, depress button in the following sequence; For example,
4
--> 7 --> 0 ---> • ST --> 0 —> 2 -->

-->
M
470.025 (Programmed into memory bank)
If there is more than a 5-second delay in entering the frequency, time will be automatically displayed and you must
re-program. If the frequency that was selected is not desired, to reprogram, simply enter new frequency as outlined above.
4. Recall
Once frequency has been programmed, for example, 156.175 is entered into channel M3, by depressing M3, the frequency
will be recalled.
5. Scanning
"SCAN

A"
To use
"SCAN
-
A"
mode, when this button is depressed, all channels from M1 through M16 will be scanned repeatedly until
a signal is received. To stop scan, depress
•ST
key. The Scan Delay control located in the rear plate of the unit is used to
delay resumption of scanning during a pause in transmission. Moving the slide switch to the positions 1, 2 and 3 varies the
holding time on a frequency for zero second (Position 1), 2 seconds (Position 2) and 4 seconds (Position 3) respectively.
6. Scanning
"SCAN
-
B"
"SCAN
-
B"
is a programmable scan mode. It allows the SX-200 to scan any combination of its 16 memory channels.
(i.e. you may scan e.g. ch. 3 and 5 or 2, 5 and 10 etc.) Programming of
"SCAN
-
B"
is quite simple, for example we wish to
scan only channels 1, 2, 15 and 16. The following operation is performed:-
PUSH

CK
key first, push
H
key 4 times and push

key 16 times (P and 10 will appear.) and push
CK
key, and push
n
key
15 times.
9. Limit Write Key, "LIM"
To enter upper and lower frequency of search range, the following keys must be depressed in sequence:
Upper frequency desired, for example:
470.000 -* ENT --> LIM
-
Lower frequency desired, for example:
-~
Now, the search between 450.000 and 470.000 is limitedly made by depressing UP or DOWN key.
To retrieve this limitter, the following operation shall be made.
ENT -> LIM
514.000 -->
CAUTION
1. When the frequency selection becomes inoperative by some entry mistakes during memory writing or scanning ("E"
(ERROR) does not appear on the display), unplug the power supply cord once, leaving power switch on and then plug it
again to clear.
2. If you attempt to program a frequency that is outside the tuning range of the receiver, an
"E"
(ERROR) appears on
the display. If this happens, simply enter a new frequency.
3. Under the condition of:
Clock switch ---- ON
Power switch ----> OFF
--~ Time displays continuously.
But if the power supply cord is disconnected and then re-connected, 89APL-E will appear in the display as error.
To retrieve this error, set the clock switch to "OFF" position and frequency readout will appear. Meanwhile if time
readout is desired, set the clock switch to "ON" position.
