If you want to monitor another frequency while
monitoring the Weather Radio in the background:
1Perform step 1 ~ 4 above.
2Press [VFO] or [MR] and turn the Tuning control to
select another frequency or memory channel.
¥ ÒWXÓ remains on the LCD.
3When the Weather Alert tone is broadcasted, the
transceiver automatically switches to the Weather
Radio frequency.
4To exit the Weather Alert Mode, press [MENU],
select Menu No. 37 (WXA), and set it to ÒOFFÓ.
Note:
uThe transceiver checks the weather alert tone every 1 second
while you are monitoring another frequency or channel.
uIf the transceiver is transmitting or receiving a signal on anotherfrequency, Weather Alert function temporarily pauses.
CHANNEL DISPLAY
While in this mode, the transceiver displays only
memory channel numbers (or Memory names if they
have been stored), instead of frequencies.
1Press [PTT]+[MR]+[ 
 ] (POWER).
¥ The transceiver displays the memory channel number
in place of the operating frequencies.
2Turn the Tuning control to select your desired
memory channel number.

SCAN
Scan is a useful function for hands-off monitoring of
your favorite frequencies.  By becoming comfortable
with all types of scan, you will increase your operating
efficiency.
This transceiver provides the following types of scans.

Note:
uWhen the CTCSS or DCS function is activated, the transceiver
stops at a busy frequency and decodes the CTCSS tone or DCS
code.  If the tone or code matches, the transceiver unmutes.
Otherwise, it resumes scanning.
uPress and hold [MONI/SQL] to pause scan in order to monitor
the scanning frequency.  Release [MONI/SQL] to resume
scanning.
uWhile the transceiver is in VOX Mode or transmitting, it causes
scan to stop (excluding Priority Scan).
uPressing [MENU] causes scan to stop.uStarting scan switches OFF the Automatic Simplex Check (ASC)
{page 38}.
uIf you press any key other than the following keys during scan,
the transceiver exits scan (excluding Priority Scan).  Priority Scan
stops while ÒPrÓ is blinking:  [F], [F] (1 s), [LAMP], [MONI/SQL],
Tuning control, and [F] then [MONI/SQL].
NORMAL SCAN
When you are operating the transceiver in VFO Mode,
2 types of scanning are available:  Band Scan and
Program Scan.
Band Scan
The transceiver scans the entire band of the frequency
you selected.  For example, if you are operating and
receiving at 144.525 MHz, it scans all the frequencies
available for the 2 m band.  (Refer to receiver VFO
frequency range in the specifications {page 122}.)  When
the current VFO receive frequency is outside the Program
Scan frequency range {page 59}, the transceiver scans
the entire frequency range available for the current VFO.
1Press [VFO].
2Turn the Tuning control to select the frequency
outside of the Program Scan frequency range. 
						

							61
3Press [VFO] (1 s) to start Band Scan.
4To stop Band Scan, press [VFO] or [PTT].
Note:
uWhile scanning, you can change the scan frequency direction by
turning the Tuning control.
uThe transceiver scans the frequency range that is stored in Menu
No. 7 (P.VFO) {page 93}.
uIf you select a frequency within the L0/U0 ~ L2/U2 range in step 3,
Program Scan {page 61} starts.
uIf you press [MONI/SQL], Band Scan temporarily pauses.Release [MONI/SQL] to resume scanning.
Program Scan
You can limit the scanning frequency range.  There are
3 memory channel pairs (L0/U0 ~ L2/U2) available for
specifying the start and end frequencies.  Program Scan
monitors the range between the start and end
frequencies that you have stored in these memory
channels.  Before performing Program Scan, store the
Program Scan frequency range to one of the memory
channel pairs (L0/U0 ~ L2/U2).
nStoring a Program Scan Frequency Range
1Press [VFO].
2Turn the Tuning control to select your desired
start frequency.
3Press [F], [MR] then turn the Tuning control to
select a memory channel from L0 ~ L2. 
						

							62
4Press [MR] to store the start frequency in the
memory channel.
5Turn the Tuning control to select your desired
end frequency.
6Press [F], [MR] then turn the Tuning control to
select a channel from U0 ~ U2, corresponding to
the channel selected in step 4.
¥ For example, if you selected L0 in step 4, select U0
for the end frequency.
7Press [MR] to store the end frequency in the
memory channel.
nPerforming Program Scan
1Press [VFO].
2Turn the Tuning control to select a frequency
within the frequency range of memory channel
L0/U0 ~ L2/U2.
3Press [VFO] (1 s) to start Program Scan.
4To stop Program Scan, press [VFO] or [PTT].
Note:
uIf you press [MONI/SQL], Program Scan temporarily pauses.
Release [MONI/SQL] to resume scanning.
uThe transceiver stops scanning when it detects a signal.uIf more than 2 Program Scan channel pairs are stored and
overlaps the frequency range among the pairs, the smaller
Program Scan memory channel number has priority. 
						

							63
uTo perform Program Scan, the ÒLÓ channel must be lower
than the ÒUÓ channel.  Otherwise, Band Scan starts {page
60}.
MEMORY SCAN
Memory Scan monitors memory channels in which you
have stored frequencies.
All-Channel Scan
The transceiver scans all of the memory channels in
which you have stored frequencies.
1Press [MR] (1 s).
¥ Scan starts from the last memory channel number and
ascends up through the channel numbers (default).
Turn the Tuning control to change the scanning
direction.
2To stop All-Channel Scan, press [MR] or [PTT].
Note:
uYou must have 2 or more memory channels that contain data,
excluding special function memory channels (L0/U0 ~ L2/U2, Pr,
and AL).
uYou can perform All-Channel Scan in Channel Display Mode{page 57}. 
						

							64
CALL SCAN
You can alternate between monitoring the Call Channel
and the current operating frequency.
1Select the frequency (in VFO or Memory Recall
Mode) you want to monitor.
¥ In VFO Mode, turn the Tuning control to select the
desired frequency.
¥ In Memory Recall Mode, turn the Tuning control to
select the memory channel you want to monitor.
2Press [CALL] (1 s) to start the Call Scan.
3The Call Channel and the selected VFO frequency or
memory channel are monitored.
4To stop Call Scan, press [PTT] or [CALL].
Note:
uYou must configure the CALL key function to ÒCALLÓ (Menu No.
18) prior to using Call Scan.  Otherwise, a 1750 Hz tone will be
transmitted.
uThe transceiver stops scanning when it detects a signal.uYou can perform Call Scan even if the recalled memory channelhas been locked out {page 67}. 
						

							65
PRIORITY SCAN
You may sometimes want to check your favorite
frequency activities while monitoring other frequencies.
In this case, use the Priority Scan function.  Priority
Scan checks the activities of the Priority Channel every
3 seconds.  If the transceiver detects a signal on the
Priority Channel, it recalls the frequency.
Note:  If you do not operate any control or key for 3 seconds after the
signal drops, the transceiver returns to the original frequency and
resumes Priority Scan.
Programming Priority Channels
1Press [VFO].
2Turn the Tuning control to select your desired
Priority Channel frequency.
3Select selective call functions, if necessary.
4Press [F], [MR].
¥ The memory channel number appears and blinks.
5Turn the Tuning control to select ÒPrÓ.
6Press [MR] to store the data on the Priority Channel. 
						

							66
Using Priority Scan
1Press [MENU] and turn the Tuning control to select
Menu No. 10 (PRI).
2Press [MENU] and turn the Tuning control to select
ÒONÓ.
3Press [MENU] to store the setting.
¥ ÒPRIÓ appears.
4Press any key other than [PTT], [LAMP], and
[MONI/SQL] to exit Menu Mode.
¥ The transceiver checks for a signal on the Priority
Channel every 3 seconds.
¥ When the transceiver detects a signal on the Priority
Channel, ÒPrÓ blinks and the frequency changes to the
Priority Channel.
¥ If you do not operate any control or key for 3 seconds
after the signal drops, the transceiver returns to the
original frequency and resumes Priority Scan.
5To quit Priority Scan, select ÒOFFÓ in step 2.
¥ You can also press any key other than [PTT], [F],
[LAMP], [MONI/SQL], [F] then [MONI/SQL] and
[F] (1 s) to exit Priority Scan while ÒPrÓ is blinking.
Note:
uIf a signal is received on a Priority Channel with a CTCSS or
DCS code programmed, the Priority Channel is recalled only
when the programmed tone/ code matches.
uPress and hold [MONI/SQL] to pause Priority Scan when the
transceiver is not displaying the Priority Channel.  Release
[MONI/SQL] to resume Priority Scan.
uIf you clear the Priority Channels {page 47}, Priority Scan stops.uIf you press any key other than the following keys while ÒPrÓ is
blinking, the transceiver exits Priority Scan: [LAMP],
[MONI/SQL], [F] (1 s), [F] then [MONI/SQL] (Squelch
adjustment) and [PTT].
