1 Safety Precautions
1. Before servicing, unplug the power cord to prevent an electrical shock.
2. When replacing parts, use only manufacturer’s recommended components for safety.
3. Check the condition of power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, make the insulation resistance test to prevent a shock hazard.
1.1 For Service Technicians
•Repair service shall be provided in accordance with repair technology information such as service manual so as
to prevent fires, injury or electric shock, which can be caused by improper repair work.
1. When repair services are provided, neither the products nor their parts or members shall be remodeled.
2. If a lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced.
3. FASTON terminals shall be plugged straight in and unplugged straight out.
•ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help prevent recurring malfunctions.
1. Cover plastic parts boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on worktable.
4. Do not grasp IC or LSI pins with bare fingers.
1.2 Insulation Resistance Test (by Insulation resistance tester)
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal part, such as
screw threads, control shafts, handle brackets, etc.
Note:
Some exposed parts may be isolated from the chassis by design. These will read infinity.
3. If the measurement is outside the specified limits, there is a possibility of shock hazard. The equipment should be
repaired and rechecked before it is returned to the customer.
1.3 Power Caution
The power socket wall outlet should be located near this equipment and be easily accessible.

2 Warning
2.1 Battery Caution
Risk of explosion if battery is replace by an incorrect type.
Dispose of used batteries according to the instructions.
2.2 About Lead Free Solder (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that
contains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.
Caution
•PbF solder has a melting point that is 50° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron with
temperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature soldering iron, please
be careful not to heat too long.
•PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (600°C).
•If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as
possible and be sure that any remaining is melted prior to applying the Pb solder.
•When applying PbF solder to double layered boards, please check the component side for excess which may flow onto
the opposite side (See figure, below).
2.2.1 Suggested Pbf Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and
Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the
manufacturer’s specific instructions for the melting points of their products and any precautions for using their product with
other materials.
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.
- 6 -

2.3 Discarding of P.C. Board
When discarding P. C. Board, delete all personal information such as telephone directory, caller list and recorded images or
scrap P. C. Board.
2.4 Note For Repairing
1. Before carrying out repair, inform the user that there is a possibility of the user data inside the equipment becoming lost.
2. There is a possibility that the equipment to be repaired contains personal data or set data, so take adequate care.
3. When we loan you substitute equipment in order to carry out repair, please initialize the user data and setting data of the
substitute equipment.
2.5 Disposal of old Equipment
This symbol on the products, packaging, and/or accompanying documents means that used electrical and electronic
products must not be mixed with general household waste.
For proper treatment, recovery and recycling of old products, please take them to applicable collection points in accordance
with your national legislation.
By disposing of them correctly, you will help to save valuable resources and prevent any potential negative effects on human
health and the environment. For more information about collection and recycling, please contact your local municipality.
Penalties may be applicable for incorrect disposal of this waste, in accordance with national legislation.
(Only for European Union and countries with recycling systems)

4 Technical Descriptions
4.1 Block Diagram
The block diagram of Video intercom system is shown in Fig 4.1.
Image signal root:
The image data is converted into NTSC signal by Camera unit, and the NTSC signal is modulated into FM signal.
FM signal is sent to the Monitor station through the interphone cable with ASK signal which modulated from command signal
and voice signal. Demodulated NTSC signal is displayed on the LCD of Monitor station.
Route to Extension monitor:
The buffered FM signal is sent to the Extension monitor through the interphone cable with ASK signal which modulated from
command signal and voice signal.
Demodulated NTSC signal is displayed on the LCD of Extension monitor.
Voice signal root:
The voice signal from the microphone of Door station is sent through the hybrid circuit(HYB), and interphone cable to the
speaker of Monitor station. While the voice from the microphone of Monitor station reaches the speaker of the Door station
through the reverse route.
Route to Extension monitor:
The voice signal from Door station is sent through another HYB, and interphone cable to Extension monitor.
In Extension monitor, The voice signal from Monitor station is sent through HYB and Sub CPU to the speaker of Extension
monitor.
While the voice from the microphone of Extension monitor reaches the speaker of the Door station through the reverse route.
Command signal route:
The CPU command on Door station is modulated to ASK signal and sent to the Monitor station.This ASK signal is
demodulated in Monitor station to pass to the CPU, and vice versa. (2-way communication)
Route to Extension monitor:
The Main CPU command of Monitor station is modulated to ASK signal and sent to Extension monitor.
This ASK signal is demodulated in Extension monitor to pass to Main CPU, and vice versa. (2-way communication)
Fig. 4.1. Video intercom system block diagram

Call Signal from Door station:
When the call button is pressed in Stand-by mode, the short between lines causes the DC voltage of the interphone cable to
go down. The monitor station detects this voltage reduction and then rings. Then LCD of the Monitor station is turned ON.
Fig. 4.2. Call signal from Door station
Communication to Extension monitor:
When the call is detected by Monitor station.
The Main CPU command of Monitor station is modulated to ASK signal and sent to Extension monitor.
This ASK signal is demodulated by Extension monitor.
Extension monitor detects this call and then rings.
Then LCD of Extension monitor is turned ON.
