THANK YOU
We are grateful you decided to purchase this
KENWOOD FM transceiver. The TM-733 series of
mobile transceivers were developed to satisfy the
requirement for a compact rig that's simple to operate
yet contains numerous sophisticated features. The
dual band operation will be appreciated by hams who
want access to VHF and UHF bands with a transceiver
smaller than some single banders.
KENWOOD believes you will be satisfied with this
product's quality and features.
PRECAUTIONS
Please observe the following precautions to prevent
fire, personal injury, and transceiver damage:
+ Do not transmit with high output power for extended
periods. The transceiver may overheat.
+ Do not modify this transceiver unless instructed by
this manual or by some other approved
KENWOOD communication.
+ Do not expose the transceiver to long periods of
direct sunlight or place the transceiver close to
heating appliances.
+ Do not place the transceiver in excessively dusty or
humid areas, or on unstable surfaces.
+ If an abnormal odor or smoke is detected coming
from the transceiver, turn OFF the power
immediately. Contacta KENWOOD service station
or your dealer.
+ The transceiver is designed for a 13.8 V power
source. Never use a 24 V battery to power the
transceiver.
+ Ensure the Front Panel of the transceiver is installed
correctly to prevent the panel from falling. Refer to
pages 17 and 111.

PREPARATION FOR MOBILE OPERATION
When operating mobile, do not attempt to configure
your transceiver while driving because it is simply too
dangerous. Stop the car first, then make the necessary
changes. Also, be aware of local laws pertaining to the
use of headphones/headsets while driving on public
roads. If in doubt, do not wear headphones while
mobiling.
MOBILE INSTALLATION
Install the transceiver in a safe, convenient position
inside your vehicle that minimizes danger to your
passengers and yourself while the vehicle is in motion.
For example, consider installing the transceiver under
the dash in front of the passenger seat so that knees or
legs will not strike the radio during sudden braking of
your vehicle. Try to pick a well-ventilated location that
is shielded from direct sunlight. Leave sufficient space
behind the Rear Panel for the transceiver fan to
exhaust warm air.
gw Installation Example
1 Install the mounting bracket using the supplied
flat washers and self-tapping screws. There are
4 washers and 4 screws supplied.
The bracket can be mounted with the bracket
opening for the transceiver facing down for
underdash mounting, or with tne opening
facing up. Study the accompanying diagram
to determine the best installation method for
your situation.

2 Position the transceiver in the bracket to
determine the best viewing angle.
3 Insert and tighten the supplied hexagonal SEMS
screws and washers. There are 2 screws and 2
washers supplied for each side of the bracket.
* Double check that all hardware is tightened to
prevent vehicle vibration from loosening the
bracket or transceiver.
DC POWER CABLE CONNECTION
Route the DC power cable supplied with the transceiver
directly to the vehicle's battery terminals using the
shortest path from the transceiver. If using a noise
filter, it should be installed with an insulator to prevent it
from touching metal on the vehicle. It is not
recommended to use the cigarette lighter socket since
some cigarette lighter sockets introduce an
unacceptable voltage drop.
To prevent the risk of short circuits, disconnect other
wiring from the negative (—) battery terminal before
connecting the transceiver. Confirm the correct polarity
of the connections before attaching the power cable;
red connects to the positive (+) terminal, black connects
to the negative (-) terminal. Use the full length of the
cable without cutting off excess even if the cable is
longer than required. In particular, never remove the
fuse holders from the cable. After completing
