Scan is a useful feature for hands-off monitoring of your
favorite frequencies.  Becoming comfortable with all
types of Scan will increase your operating efficiency.Note:u
Adjust the squelch level before using Scan.  Selecting a squelch level
too low could cause Scan to stop immediately.
u
You cannot start Scan while Tone Alert is ON.
u
While using CTCSS, Scan stops for any signal received; however,
you will hear audio only when the signal contains the same CTCSS
tone that you selected.
u
Starting Scan switches OFF the Automatic Simplex Check.

SELECTING SCAN RESUME METHODThe transceiver stops scanning at a frequency (or
memory channel) on which a signal is detected.  It then
continues scanning according to which resume mode
you select.  You can choose one of the following modes.
The default is Time-operated mode.
¥Time-Operated mode
The transceiver remains on a busy frequency (or
memory channel) for approximately 5 seconds, and
then continues to scan even if the signal is still
present.
¥Carrier-Operated mode
The transceiver remains on a busy frequency (or
memory channel) until the signal drops out.  There is
a 2 second delay between signal drop-out and scan
resumption.
¥Seek mode
The transceiver remains on a busy frequency (or
memory channel) even after the signal drops out and
does not automatically resume scanning.Note:  To temporarily stop scanning and monitor weak signals, press and
hold [MONI].  Release the key to resume scanning.

MEMORY SCANUse Memory Scan to monitor all memory channels
programmed with frequency data.
1Select the desired band.
2Press [MR] (1 s).
¥ Scan starts with the channel last recalled.
¥ The 1 MHz decimal blinks while scanning is in progress.
¥ To reverse scan direction, press [UP] (upward scan) or
[DWN] (downward scan).
3To quit Memory Scan, press [ESC].Note:u
On the current band at least 2 or more memory channels must
contain data and must not be locked out.
u
The L0 to L9 and U0 to U9 memory channels are not scanned.
u
You can also start Memory Scan when in Channel Display mode.
While Scan is being interrupted, the channel number blinks.
VFO SCANVFO Scan monitors all frequencies tunable on the band,
using the current frequency step size.
1Select the desired band.
2Press [VFO] (1 s).
¥ Scan starts at the frequency currently displayed.
¥ The 1 MHz decimal blinks while scanning is in progress.
¥ To reverse scan direction, press [UP] (upward scan) or
[DWN] (downward scan).
3To quit VFO Scan, press [ESC].

Locking Out a Memory ChannelSelect memory channels that you prefer not to
monitor while scanning.
1Recall the desired memory channel.
2Press [F], [0] to switch Lockout ON (or OFF).
¥ A star appears above the channel number when the
channel is locked out.
Note:u
The L0 to L9 and U0 to U9 memory channels cannot be locked
out.
u
If you have recalled a memory channel on the non-current band
(A or B), you cannot select the same channel on the current band
to lock out.
MHz SCANMHz Scan monitors a 1 MHz segment of the band, using
the current frequency step size.  The current 1 MHz digit
determines the limits of the scan.  For example, if the
current frequency is 145.400 MHz, then the scan range
would be from 145.000 MHz to 145.995 MHz.  The exact
upper limit depends on the current frequency step size.
1Select the desired band.
2Press [VFO] to select VFO mode.
3Select a frequency within the desired 1 MHz
segment.
4Press [MHz] (1 s) to start MHz Scan.
¥ Scan starts at the frequency currently displayed.
¥ The 1 MHz decimal blinks while scanning is in progress.
¥ To reverse scan direction, press [UP] (upward scan) or
[DWN] (downward scan).
5To quit MHz Scan, press [ESC].

CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)
You may sometimes want to hear calls from only specific
persons.  The Continuous Tone Coded Squelch System
(CTCSS) allows you to ignore (not hear) unwanted calls
from other persons who are using the same frequency.
First select the same CTCSS tone as selected by the
other persons in your group.  A CTCSS tone is
subaudible and is selectable from among the 38
standard tone frequencies.Note:  CTCSS does not cause your conversation to be private.  It only
relieves you from listening to unwanted conversations.
SELECTING A CTCSS FREQUENCY1Press [A/B] to select band A or B.
¥ If necessary, press [F], [A/B] to recall the sub-band.
2Press [F], [4] to select ÒFÐ4 (CTCSS FREQ)Ó.
3Press [UP]/ [DWN] to select the appropriate CTCSS
frequency.
¥ The selectable frequencies are the same as for the tone
frequency.  See the table given in ÒSelecting a Tone
FrequencyÓ {page 22}.

¥ If necessary, press [F], [A/B] to recall the sub-band.
2Press [F], [3] to switch the CTCSS function ON (or
OFF).
¥ ÒCTÓ appears when CTCSS is ON.
You will hear calls only when the selected tone is
received.  To answer the call, press and hold the PTT
switch, then speak into the microphone.Note:u
You cannot use the CTCSS and Tone functions simultaneously.
Switching the CTCSS function ON after activating the Tone function
deactivates the Tone function.
u
If you select a high CTCSS frequency, receiving audio or noise that
contains the same frequency portions may cause CTCSS to function
incorrectly.  To prevent noise from causing this problem, select an
appropriate squelch level {page 8}.

CTCSS FREQ. IDThis function scans through all CTCSS frequencies to
identify the incoming CTCSS frequency on a received
signal.  You may find it useful when you cannot recall the
CTCSS frequency that the other persons in your group
are using.
1Press [F], [4] (1 s) to activate the function.
¥ The CTCSS function is switched ON.
¥ If you access ÒFÐ4 (CTCSS FREQ)Ó using [UP]/ [DWN]
in Function Select mode, press [OK] (1 s) to activate the
function.
¥ To reverse scan direction, press [UP] (upward scan) or
[DWN] (downward scan).
¥ To quit the function, press [ESC].
¥When the CTCSS frequency is identified, the identified
frequency appears and blinks.
2Press [OK] to program the identified frequency in
place of the currently set CTCSS frequency.
¥ The previous frequency display is restored with the
CTCSS function remained ON.
¥ Press [ESC] if you do not want to program the identified
frequency.
¥ Press [UP]/ [DWN] while the identified frequency is
blinking, to resume scanning.
Note:  Received signals are audible while scanning is in progress.

DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS
The keys on the keypad also function as DTMF keys; the
12 keys found on a push-button telephone plus 4
additional keys (A, B, C, D).  This transceiver provides
10 dedicated memory channels.  You can store a DTMF
number (16 digits max.) with a memory name (8 digits
max.) in each of the channels to recall later for a quick
call.
Some repeaters in the U.S.A. and Canada offer a
service called Autopatch.  You can access the public
telephone network via such a repeater by sending DTMF
tones.  For further information, consult your local
repeater reference.MANUAL DIALINGManual Dialing requires only two steps to send DTMF
tones.
1Press and hold the PTT switch.
2Press the keys in sequence on the keypad to send
DTMF tones.
¥ The corresponding DTMF tones are transmitted.
n
TX HoldThis function makes the transceiver remain in
transmit mode for 2 seconds after you release each
key.  So you can release the PTT switch after
beginning to press keys.
1Press [MENU] to enter Menu mode.
2Press [1], [3], [3] to select Ò1Ð3Ð3 (TX HOLD)Ó.
3Press [UP]/ [DWN] to switch the function ON (or
OFF).
4Press [OK] to complete the setting.
5Press [MENU] to exit Menu mode.
