ENVIRONMENT WHERE SPARKS COULD CAUSE AN
EXPLOSION.

◆
NEVER DISCARD OLD BATTERIES IN FIRE BECAUSE
EXTREMELY HIGH TEMPERATURES CAN CAUSE BATTERIES
TO EXPLODE.
1 To remove the battery cover, slide the cover outward
while slightly pushing on the grooves on the cover.
Note:
◆
It is strongly recommended to use high quality alkaline batteries
rather than manganese batteries, to enjoy longer periods of battery
life. Do not use commercially available NiCd batteries.
Grooves
◆
If you will not use the VC-H1 for a long period, remove the batteries
from the VC-H1.
◆
◆
Do not use different kinds of batteries together.
When the battery voltage is low, replace all four old batteries with
new ones.
The approximate lives of alkaline batteries depending on
the operation status are shown below:
2 Insert four AA (LR6) alkaline batteries.
•
Be sure to match the battery polarities with those
marked on the VC-H1.
Camera ON
50 minutes
2 hours
Monitor ON (memory recalled)
Monitor OFF
6 hours
When the batteries become almost empty while the
TX/RX indicator is green, the indicator starts blinking.
Replace the batteries at that time. This function,
however, does not operate while Fast FM mode is
currently selected.

ATTACHING THE STRAP
CONNECTING THE AC ADAPTER
If you want, attach the provided strap to the bottom of
the VC-H1. The strap can be used to hang the VC-H1
around your neck.
Use the provided AC adapter to connect the VC-H1 to an
AC outlet if you want to use AC power.
WARNING!
◆
USING AN AC ADAPTER OTHER THAN THE PROVIDED
ADAPTER CAN CAUSE FIRE OR PRODUCT DAMAGE.
◆
DO NOT USE AN EXTENSION CABLE UNLESS ABSOLUTELY
NECESSARY. IMPROPER EXTENSION CABLES CAN CAUSE
FIRE OR ELECTRIC SHOCK.

CONNECTION WITH A HANDY TRANSCEIVER
REMOVING/ REINSTALLING THE CAMERA UNIT
Note: Turn OFF the power to the VC-H1 before removing or reinstalling
the camera unit.
Use the provided cable to connect the VC-H1 with a
handy transceiver.
To remove the camera unit, first turn it so that it crosses
at right angles with the main unit.
Note: The VC-H1 functions as a speaker microphone only when
connected with a handy transceiver. You need not switch ON the VC-H1.
1 Confirm that the power switches of both the VC-H1
and transceiver are OFF.
2 Connect the appropriate end of the provided cable to
the DATA port of the VC-H1.
•
To remove the cable from the VC-H1, pull the cable
connector downward while pushing its tabs from both
sides.
or
To remove
3 Connect the other end of the cable to the speaker/
microphone jacks on your handy transceiver.
To reinstall the camera unit, first position the port on the
camera unit over the port on the main unit so that the
two units cross at right angles.
Note: The compatible handy transceivers are TH-26, TH-46, TH-27,
TH-47, TH-28, TH-48, TH-22, TH-42, TH-77, TH-78, TH-79, and TH-G71.
An optional PG-4T cable is available for connecting with a TM-255,
TM-455, TM-733, TM-V7, or TM-G707 transceiver. To make a cable for
connecting with a TS-570 or TS-870 transceiver, you may obtain an
optional connector kit (E59-0407-08) which mates with the VC-H1 DATA
port. For the above options, contact your authorized KENWOOD dealer,
customer service, or service center.
Note: The camera unit has a structure that allows the plug assembly to
be slightly moved. This is aimed at absorbing stress to be caused when
the camera unit is turned.

QUICK USE
If you have a handy transceiver, the steps given here will allow you to try SSTV with
your friend right away.
Note: To correctly receive or transmit images, you and your friend have to select the same SSTV mode. If you
prefer using a mode other than Robot (color) 36 which is the factory default, see “SELECTING A SSTV MODE”
{page 7} and “RECEIVING IMAGES” {page 10}.

SELECTING A SSTV MODE
To correctly transmit or receive images,
you and the other party have to select
the same SSTV mode. So first consult
with your party about the mode to be
used. You can select either Robot
(color) 36 or Fast FM; the factory default
is Robot (color) 36.
Note: The Fast FM mode is available only when
using a TM-255, TM-455, TM-733, TM-V7, or
TM-G707 transceiver; 9600 bps must be selected on
the transceiver as the data transfer rate. For details,
contact your authorized KENWOOD dealer,
customer service, or service center. In Fast FM
mode, the VC-H1 does not output audio from the
speaker while receiving an image, and does not
function as a speaker microphone.

store a maximum of 10 desired
images.
CAPTURING IMAGES
The VC-H1 has 10 memory channels to
store captured images.
• When all channels are full, the
currently selected channel is
overwritten with a newly captured
image.
1 Slide the PWR switch upward to turn
the power ON.
•
The TX/RX indicator lights green.

Note:
◆
While capturing images, the VC-H1 does not
receive images sent from other parties.
4 Press [S] again to capture the image.
◆
If no operation is performed for approximately
30 seconds with Battery Saver ON {page 11}, the
camera and monitor are deactivated; the default
is ON.
•
When capturing is completed, the
camera is deactivated and the TX/RX
indicator lights green again.
◆
◆
Pressing [S] again immediately after activating
the camera and monitor may cause the captured
image to be distorted; the camera is not yet
ready for image capture.
5 Press [MR] to store the captured
image in a memory channel.
The VC-H1 does not allow you to specify an
individual image to be erased. To erase
unnecessary images, use one of the following
methods:
•
You may skip this step if you do not
store the image.
•
Perform Memory Reset to erase all images
at one time {page 11}.
•
When all channels are full, recall the
unnecessary image, capture a new image,
then press [MR].

• You may just look at the LCD monitor
and focus the camera onto an object
instead of recalling an image; you
need not press [S] to capture an
image.
TRANSMITTING IMAGES
When an appropriate SSTV mode and a
desired image is selected, the VC-H1 is
ready to transmit images.

When the VC-H1 receives an image
signal, it automatically identifies and sets
the appropriate SSTV mode. The
compatible modes are listed below:

Note:
◆
When you fail to receive the first portion of an
image signal in a mode other than AVT 90, AVT
94, and Fast FM, pressing [RX] allows you to
receive the remaining portion. However,
because of possible insufficient synchronization,
the VC-H1 could show an inappropriate color of
an image, or fail to receive an image even if the
TX/RX indicator lights orange.
The automatically identified SSTV mode is used
for your next transmission unless the mode is
manually changed. If the identified mode is
neither Robot (color) 36 nor Fast FM, switching
OFF the VC-H1 causes it to restore the

If using a handy transceiver, switch OFF Battery
Saver. When Battery Saver is ON, the
transceiver may fail to receive an image.
If using a TH-G71 transceiver, increasing the
audio volume beyond a certain amount may
cause the transceiver to fail to receive an image.

You can also connect a computer to the DATA port of the
VC-H1 in order to control the VC-H1 via the computer.
This, however, asks you to manually send ST commands

A STC command should consist of a command name,
space, call sign, comma, color parameter, and [CR];
ex. STC JA1YKX, 1 [CR]. You can enter up to 8
characters as a call sign, using “0” to “9”, “A” to “Z”,
“/”, “-”, “!”, “?”, or a space. The parameters of call
sign colors are listed below:

■ Commands Format
The formats of STM and STR commands are the
same as of STC commands except that a message or
RSV replaces a call sign; ex. STM CQ SSTV, 2[CR].
The characters which can be entered are also the
same as for STC commands.
Note: Use capital letters to enter a command name.
A STS command should consist of a command
name, space, parameter, and [CR]; ex. STS 0 [CR].
