DISASSEMBLY
1.1 REPLACING THE FUSE
CAUTION
Before replacing a fuse and in order to prevent a recurrence of the same trouble, investigate what caused the
fuse to blow, repair it and confirm normal operation. To
protect the equipment and provide safety, be sure to
replace with a fuse having the specified part number.
(1) Set the power switch to OFF.
(2) Remove the POW board. (See section 1.6.3)
(3) Fuse F1 is located on the POW board.
(For the part No. of fuse, see Symbol No. 29 on page 4-2.)

1.5 REPLACING THE CCD IMAGE SENSOR
䡵 The image sensor is interchangeable only with a specified
image sensor.
䡵 New image sensors and crystal filters should be handled so
as not to leave fingerprints or grease on their glass surfaces.
To remove attached dirt or grease, blow on the glass surface
until it becomes misted then wipe it gently with a cotton
swab. (Do not use alcohol or other similar substances.)
䡵 After replacement, all of the adjustments should be performed
from the beginning.
䡵 Note that the image sensor is susceptible to static damage.
Be sure to take anti-static measures before replacing it.
䡵 After an image sensor has been removed, an electrical charge
may remain on the terminals of the camera circuit for a certain period of time.
If a new image sensor is inserted into the socket in this condition, the image sensor may be instantly damaged by the
remaining electric charge. To prevent this happening, wait a
while (2 to 3 minutes) after removing an image sensor until
inserting another one in the socket.
(5) Remove the two screws

(1) Start-up
1) Press the “MENU” button on the RM-P2580 for three
seconds to open the SETUP screen (see fig.2-5-2).
2) Use the “PAN/TILT” control lever to move the cursor to
“CAMERA”.
3) If the “SET” button is pressed on the RM-P2580 and
then the “ENTER” button is pressed four times within
four seconds, the SERVICE MENU will appear.
4) Use the “PAN/TILT” control lever to move the cursor to
“ADJUST”.
5) Press the “SET” button on the RM-P2580 to enter the
ADJUST mode (Fig. 2-5-1).
(2) Adjustment and Saving the Settings
Follow the same steps as described in 2.5.1 (2) and (3) except that the ”PAN/TILT control lever is used in place of the
“UP”, ”DOWN”, ”LEFT”, ”RIGHT” buttons, and the “SET
button on the RM-P2580 is used in place of the “SET” button. To exit from the SETUP screen, press the “MENU”

2.6 ADJUSTMENT OF THE WIDE-ANGLE LIMIT POSITION
• This is to adjust the wide-angle limit position for the zoom ring. This instrument is delivered after the camera has been adjusted.
Thus, there are no adjustment needs except for the replacement of the lens assemblies.
• This unit uses a variable-focal lens, if the wide-angle limit position is not in the right position, the correct focus may not be
obtained depending on the zoom position. Thus, the following adjustment must be performed when replacing the lens assembly.

DIAGRAMS AND CIRCUIT BOARDS
SCHEMATIC DIAGRAM NOTES
• Schematic safety precaution
! Parts are safety related parts.
When replacing them, be sure to use the specified parts.
• Voltage and waveform measurements
Voltage: Measured with digital voltmeter in DC range;
lens closed.
Waveform: Gray scale illuminated at more than 4000 lux at
3200K lighting.
• Unit of value
Unless otherwise specified
1) Resistance is in Ω (1/6 W)
2) Capacitance is in µF
3) Inductance is in µH
REPLACING SURFACE MOUNT “CHIP” COMPONENTS
• Some resistors, shorting jumpers (0 Ω resistance), ceramic
capacitors, transistors, and diodes are chip parts. These chip
parts cannot be reused after they are once removed.
• Chip resistors used in some circuits are of high precision
type having little error in resistance.
To demonstrate the full capacity of this set, place an order
for proper parts referring to the diagrams and parts lists in
the section 5.
• Soldering cautions:
1) Do not apply heat for more than 3 seconds.
2) Avoid using a rubbing stroke when soldering.
3) Discard removed chips; do not reuse them.
4) Supplementary cementing is not required.
5) Use care not to scratch or otherwise damage the chips.
