MICROPROCESSOR RESET
If your transceiver seems to be malfunctioning,
resetting the microprocessor may solve the problem.
The following 3 reset modes are available.  When
performing the reset, you may lose memory data and
stored information.  Back up or write down important
data before performing the reset.
INITIAL SETTINGS
For each VFO, the factory defaults for the operating
frequency and mode are as follows.
¥ A-band:  144.000 MHz/ FM
¥ B-band:  440.000 MHz/ FM (TH-F6A)
B-band:  430.000 MHz/ FM (TH-F7E)
The Memory channels have no data stored.  Refer to
pages 19 and 20 for the Call Channels and
Information Channels default values.
VFO RESET
This resets the transceiver parameters excluding the
Menu contents and Memory channel contents.
Note:  Menu No. 4 (PROG VFO) and No. 6 (OFFSET) return to the
factory default values.
MENU RESET
This resets the parameters only in the Menu items to
factory default values.
FULL RESET
This resets all transceiver parameters to the factory
default values.
PERFORMING RESET
There are 2 ways to enter the reset mode selection.
However, the transceiver must be configured to the
Lock function OFF {page 38}.
When the transceiver is turned OFF:
1Press [F]+[ 
 ] (POWER).
¥ All indicators are lit.
2Release [F].
¥ Proceed to step 3 {below}.
From the Menu:
1Press [MNU].
2Turn the Tuning control or press [
]/ [] to select
Menu No. 31 (RESET?).  Press [
] or [MNU].
3Select the reset mode by turning the Tuning
control or press [
]/ [].  If you select ÒNOÓ, the
transceiver exits the reset mode.
4Press [] or [MNU] to proceed.
¥ If you press any keys, other than [LAMP] and
[MONI], the transceiver exits the reset mode.
¥ A reset confirmation message appears.
5Press [] or [MNU] to reset the transceiver.
¥ If you press any keys, other than [LAMP] and
[MONI], the transceiver exits the reset mode.

15  TROUBLESHOOTING
OPERATION NOTICES
The transceiver has been designed and engineered
to avoid possible hardware glitches.  However, you
may notice the following symptoms when you operate
the transceiver.  These symptoms are not
malfunctions.
OPERATING VOLTAGE
As stated in ÒSPECIFICATIONSÓ {page 53}, this
transceiver operates on a DC voltage from 5.5 V ~
7.5 V DC (battery terminal) or 12.0 V ~ 16.0 V DC
(DC IN jack).  If you find that the transceiver cannot
be switched ON, or ÒVOLTAGE ERRORÓ appears, the
supplied power source may be outside of the
specified range.
In such a case, remove the DC power cable from the
transceiver immediately and confirm that the supplied
voltage is within the specified range.
TUNING IN SSB/ CW MODE
The transceiver uses a general purpose IF filter to
receive signals in LSB, USB, CW and AM modes.
So, when you receive signals in LSB or USB mode,
the opposite side band signal is not fully attenuated.
At the same time, since the same filter is used for CW
reception, you may have difficulties seperating the
CW signal from other signals in the crowded band.
To best tune in to a SSB signal, follow the instruction
below.
When you receive signals in USB mode:
1Turn the Fine Tuning function ON {page 35}.
2Tune to the target signal while starting at a lower
frequency, using the Tuning control.
When you receive signals in LSB mode:
1Turn the Fine Tuning function ON {page 35}.
2Tune to the target signal while starting at a higher
frequency, using the Tuning control.
RECEIVING IN AM BAND
If you receive a weak signal in AM band, you may
notice a high pitched squealing noise in the
background.  This noise is generated by the internal
DC/DC converter and it cannot be removed.
RECEIVING SIGNALS IN CITIES
When you receive signals in cities, the receiverÕs
entire S-meter may light up without receiving any
strong signals.  This happens when the RF amplifier
in the receiver is overloaded by strong interference
signals that are nearby.  In this case, turn the
Attenuator function ON {page 36} to reduce the
interference signal level.  You may further have to
adjust the volume level while receiving the target
signal.
BEAT AND NOISE
When you have the same 2 m, 1.25 m (TH-F6A
only), and 70 cm band frequencies for both A and
B-band receiver s, the Visual Scan may indicate the
signals on the bar-graph display even if no signal is
monitored on the A-band  receiver.   This error occurs
due to the internal spurious harmonics that are
generated by the B-band-receiver.  Refer to
ÒINTERNAL BEATSÓ {below} for the frequencies.
You may also hear some noise in the receiving signal
in the following cases.
¥ You perform any scan on the other receiver.
¥ You perform the Visual Scan on the B-band
receiver.
TRANSMISSION
If you continuously transmit for more than 3 minutes
at high power (5 W), the transceiver becomes warm.
If you continue or repeat the transmission before the
transceiver cools down, the thermal protector
automatically decreases the output power to 0.5 W.
ÒHÓ also blinks at the same time.  If this happens, let
the transceiver cool down for a while before
transmitting again.
INTERNAL BEATS
If one of the formulas on the next page is true, the
S-meter moves without receiving any signals or you
cannot receive any signals.  This is inevitable when
you use superheterodyne receivers.
