CONNECTING WITH A REGULATED POWER SUPPLYTo connect the transceiver with an appropriate regulated
power supply, use an optional PG-2W DC cable.
1Confirm that the power switches of both the
transceiver and power supply are OFF.
2Connect the optional PG-2W DC cable to the power
supply; red lead to positive (+) terminal, and black
lead to negative (Ð) terminal.
3Connect the barrel plug on the DC cable to the DC IN
jack on the side of the transceiver.Note:u
Only use the power supplies recommended by your authorized
KENWOOD dealer.
u
The supply voltage must be between 5.5 V and 16 V to prevent
damaging the transceiver.  If input voltage exceeds approximately
18 V, warning beeps sound and a warning message appears.

To connect with an external 24 V power source via a DC-DC
converter, only use the optional PG-3J Cigarette Lighter cable.
Using the PG-2W DC cable in this situation may cause a fire.
Note:  If input voltage exceeds approximately 18 V, warning beeps sound

OPERATING BASICS
SWITCHING POWER ON/OFF1Press the POWER switch (1 s) to switch ON the
transceiver.
¥ A double beep sounds.
2To switch OFF the transceiver, press the POWER
switch (1 s) again.ADJUSTING VOLUMETurn the VOL control clockwise to increase the audio
level and counterclockwise to decrease the audio level.¥ If background noise is inaudible because of the Squelch
function, press and hold [MONI], then adjust the VOL
control.  While pressing [MONI], you will hear background
noise.
SELECTING A BANDPress [A/B] to select band A or B.¥ The cursor indicates the current band.SELECTING A FREQUENCYPress [UP]/ [DWN] or turn the Tuning control to select a
frequency.¥ Pressing and holding [UP]/ [DWN] causes the frequency to
step repeatedly.
¥ To change frequencies in steps of 1 MHz, press [MHz] first.
The 1 MHz digit blinks.  Pressing [MHz] again cancels this
function.
¥ You can also select frequencies by directly entering digits
from the keypad.  See ÒDIRECT FREQUENCY ENTRYÓ
{page 45}.

listening to background noise output from the speaker
when no signals are present.  The appropriate squelch
level depends on ambient noise conditions.  You can
program a different level for band A and B.

u
The recommended duty cycle is 1 minute of transmission and
3 minutes of reception.  Extended transmissions in the high
power mode may cause the back of the transceiver to get hot.
u
Transmitting with the supplied antenna near other electronic
equipment can interfere with that equipment.  Also, transmitting
near a poorly regulated power supply, that is not recommended
by KENWOOD, may cause the power supply to output an
extremely high voltage.  This voltage could damage both your
transceiver and any other equipment connected to the power
supply.
Note:  If input voltage exceeds approximately 18 V while using an
external power source, warning beeps sound and a warning message
appears.
n
Selecting Output PowerSelecting lower transmit power is a wise method to
reduce battery consumption, if communication is still
reliable.  You can program a different power for band
A and B.
Press [F], [MENU] to select high (default), low, or
economic low power (lowest).¥ ÒHÓ, ÒLÓ, or ÒELÓ appears to show the current selection.
TRANSMITTING1To transmit, press and hold the PTT switch and speak
into the microphone in a normal tone of voice.
¥ Indicator A or B lights red depending on which band you
have selected.
¥ The battery meter appears to show the current relative
battery charge.
¥ Speaking too close to the microphone, or too loudly,
may increase distortion and reduce intelligibility of your
signal at the receiving station.
2When you finish speaking, release the PTT switch.Time-Out Timer:  Holding down the PTT switch for more than 10
minutes causes the transceiver to generate a beep and stop transmitting.
Release, then press the PTT switch to resume transmitting.  You cannot
switch this function OFF.

12CURSOR KEYSThis transceiver employs 4 cursor keys so that you can
program most of the functions with only one hand.
UP/ DWN keys
The UP/ DWN keys function in the exact same way as
the Tuning control.  These keys change frequencies,
memory channels, or other selections, depending on the
current transceiver mode.Note:  You can use the Tuning control instead of the UP/ DWN keys in
each operation step.  This manual often omits the Tuning control to
simplify descriptions.OK key
Press to move to the next step or to complete the setting
in various selection modes such as Function Select or
Menu mode.
ESC key
Press to move back to the previous step or to quit the
setting in various selection modes such as Function
Select or Menu mode.
BAND A & BIn this manual, bands recalled beside Ò
Ó and Ò
Ó are
referred to as band A and band B.  The band A default is
VHF (144 MHz) and the band B default is UHF.  In band
A you can also recall a 118 MHz sub-band (TH-D7A
only).  In band B you can also recall a VHF (144 MHz)
sub-band.
This transceiver is capable of simultaneously receiving
on 2 bands (A and B).  So, for example, it is possible to
receive packet data on one VHF frequency while
receiving audio on another VHF frequency.  To transmit,
you must select either band.  Ò
Ó indicates the current
data band {page 55}.
The following diagram should help you understand how
to select or recall the desired band.
Note:u
You cannot recall another band by pressing [F], [A/B] in Memory
Recall mode.  First press [VFO] to select VFO mode.
u
The 118 MHz band cannot be used for transmitting.
TH-D7A only

BASIC TRANSCEIVER MODESThis section introduces you to the basic modes you can
select on this transceiver.
VFO mode
Press [VFO] to select.  In this mode you can change the
operating frequency by pressing [UP]/ [DWN] or entering
digits directly from the keypad {page 45}.
Memory Recall mode
Press [MR] to select.  In this mode you can recall the
desired memory channel by pressing [UP]/ [DWN] or
entering digits directly from the keypad {page 28}.  For
further information, refer to ÒMEMORY CHANNELSÓ
{page 26}.Function Select mode
Press [F] to select.  In this mode you can scroll FÐ1
through FÐ8 (except FÐ6) by pressing [UP]/ [DWN]; to
access FÐ6, first select the 118 MHz band {page 51}.
After accessing the desired function, press [OK], then
press [UP]/ [DWN] to select the desired parameter.
Last, press [OK] again to complete the setting.  After
recalling a memory channel, you can also access FÐ0
and FÐ9.  On the TH-D7E you cannot access FÐ6.
Pressing [F], [0] ~ [9] is a much simpler method than the
above.  For example, pressing [F], [1] switches the Tone
function ON or OFF.  This method is described in the
appropriate sections in this manual.
Menu mode
Press [MENU] to select.  In this mode you can access
the desired menu item by pressing [UP]/ [DWN] and
[OK] or entering digits directly from the keypad.  For
further information, refer to ÒMENU SET-UPÓ {page 16}.
