' BATTERY LOADING

Your VT»! 10 employs two Type D rechargeable batteries.
Instructions for landing are clearly written on the inside 0!
the battery lid.

Your VI-I I0 is equipped with a Battery Voltage Indicator-
When the Battery Voltage Indicator reaches the white line
between green and red, the batteries must be recharged. DO
NOT WAIT UNTIL THE INDICATOR RtiACIIliS Tlll-i
Rlil) ZONE. For re-clmrging instructions. see page 14 at
this manual.

I TAPE VIEW WINDOW

Your V'l--Iltl is equipped with 2: Tape View Windmv
(Fig. 14}. Tape position can easily be determined without
opening the recorder lid.

I CONNI-LC'I'ING TV MONITOR VM-l [0
AND RECORDER VT-I ID

As shown in Fig.15, line up the VM-I I0 with the VT-l l0
and connect the VM-I IO's protruding plug into receptacle
provided on the left side of VT-I IO.

Fit the two units together tightly and tighten screws 59
and 123 (Fig. IS).

When separating TV Monitor and Recorder, reverse the
above procedure.

Note :

Video recording is possible even with the VM-l lflscparated
from the recorder. However, if they are connected. the
operator is able to perfectly focus the picture being
recorded while viewing the monitor screen.

Nolc :

VMC-J Monitor Connection Cord (optional accessory} can
also be used for connecting the VM-HO to the VTJIO.

9. TAPE SPLICING AND EDITING

(-ut tape diagonally with an overlap so that the ends are
lined up (Cutting tape on diagonal eliminates detection of
the splice in recording].

Cover aligned ends with SI-LICthi TAPE. Press firmly.
exerting pressure to secure ends evenly. Trim of! excess
splicing tape {Cut into recording tape very slightly as
illustrated by dotted lines. This eliminates the possibility ol
a sticky splice}. Splicing of tape using scissors requires
skillful work. With our specially designed PORTABLE
SPLICER. splicing can be done very smoothly.

Caution:

It is imperative that splicing be completely smooth. If not.
the video heads will he irreparably damaged.

ll}. TAPE ERASING

Any signal information previously recorded on a tape will
he erased automatically as a new recording is made on the
same tape. For erasing only. thread the tape. and set
recorder to normal record position. There should be no
plugs connected to recorder-s input jacks. A BULK 'l'APli
ISRASliR is recommended for quick and complete erasure
(AKA! Model ATE? is highly recommended).

ll. HEAD DEMAGNETIZING
[STATIONARY HEADS ONLYl

Normally the steel pole pieces which form a part of the
recording and playback heads become slightly magnetized-
The effect of slight head magnetization is that it partially
erases the tape. especially at high frequencies. Generally,
this condition can be detected by the less of high frequency
reSponse which cannot be canceled through head align-
ment. Severe magnetization {which may be caused by using
magnetized tools in the vicinity of the heads) will result in
noise or considerable distortion in addition to the loss of
high frequency response. Although Model VT-llO already
has a built'in Head Demagnetizing Circuit, it is recom-
mended that head tie-magnetizing be performed period-
ically. This can be accomplished by touching the heads
lightly with the demagnetizer and making several small
circular motions over all stationary head surface areas as
well as the head housing.

Note :

To avoid scratching the head surface. we suggest that you
cover both prongs of the head demagnetizcr with a sort of
masking tape.

Caution :

Do not attempt to demagnetize the Video Heads as they
may be damaged.
