ATTACHMENTS, OPTIONS
MANUAL SWITCH
When this switch (2) is pressed, an image of a camera appears on
the monitor display.
At that time, a mark "CAM1" appears on the upper left side of the
display and a figure "5" on the upper right side of the display.
REMARK
When the manual switch is pressed to call an image and the
operation is suspended thereafter, the image disappears in
approx. 5 minutes, turning the display into a waiting condition.
This is a function in case the operator forgets to switch off the
display (timer function).
The time until the monitor display is automatically switched off
is shown on the upper right side of the display. It changes by
minute and in the descending order as 5→4 →3 → 2 → 1.
Moreover, when the remaining time comes down to just 10
seconds before the monitor display goes off, the last figure "1"
on the upper right side begins to flash.
When the manual switch is pressed to call an image and it is
pressed again while the image is shown on the monitor display,
it remains on the display for approx. 5 more minutes from the
moment the switch is pressed.
When the gearshift lever is in the "R" position, the timer function
does not work.
ZOOM/IRIS SWITCH (REVERSE LIGHT COMPENSATION SWITCH)
Zoom Function (press the switch)
By pressing this switch (3), an image on the monitor display can be
enlarged by 1.4 times.
At that time, a mark of "ZOOM" is shown on the upper right side of
the display.
When the switch is pressed again, "ZOOM" disappears and the
display returns to the original image.
Iris Function (Reverse Light Compensation Function) (Keep the switch pressed for more than 1 second.)
When the iris function is activated (turned "ON"), the whole monitor display becomes brighter. As a result, some portion on the
display becomes difficult to read or discern, while it is easy to do so with the iris function turned "OFF". Therefore do not use this
function except when it is necessary to read or see a dim portion.
When it is difficult to see a monitor display due to a reverse light, keep this switch (3) for more than 1 second, and
then the iris function (reverse light compensation function) is turned "ON", turning the display brighter and making
it easier to see.
At that time, a mark of "IRIS" appears on the upper left side of the display.
If the switch is further kept pressed for more than 1 second, the iris function (reverse light compensation function)
is turned "OFF" and "IRIS" mark goes off.
