WARNING

Do not use solder containing lead. Note: This product has been manufactured using lead-free solder in If replacing existing solder containing lead with lead-free sol- order to help preserve the environment. der in the soldered parts of products that have been manufac- Because of this, be sure to use lead-free solder when carrying tured up until now, remove all of the existing solder at those out repair work, and never use solder containing lead. parts before applying the lead-free solder. Lead-free solder has a melting point that is 30 - 40°C (86 - 104°F) higher than solder containing lead, and moreover it does not contain lead which attaches easily to other metals. As a result, it does not melt as easily as solder containing lead, and soldering will be more difficult even if the temperature of the soldering iron is increased. The extra difficulty in soldering means that soldering time will increase and damage to the components or the circuit board may easily occur. Because of this, you should use a soldering iron and solder that satisfy the following conditions when carrying out repair work. Soldering iron Use a soldering iron which is 70 W or equivalent, and which lets you adjust the tip temperature up to 450°C (842°F). It should also have as good temperature recovery characteris- tics as possible. Set the temperature to 350°C (662°F) or less for chip compo- nents, to 380°C (716°F) for lead wires and similar, and to 420°C (788°F) when installing and removing shield plates. The tip of the soldering iron should have a C-cut shape or a driver shape so that it can contact the circuit board as flat or in a line as much as possible. Solder Use solder with the metal content and composition ratio by weight given in the table below. Do not use solders which do not meet these conditions. Metal content Tin (Sn) Silver (Ag) Copper (Cu) Composition 96.5 % 3.0 % 0.5 % ratio by weight Lead-free solder is available for purchase as a service tool. Use the following part number when ordering: Part name: Lead-free solder with resin (0.5 mm dia., 500 g) Part number: VJ8-0270 – 2 –, 1. OUTLINE OF CIRCUIT DESCRIPTION Pin 1 1-1.

Key Operation – 10 –, 4. Power Supply Control The 8-bit microprocessor controls the power supply for the overall system. The following is a description of how the power supply is turned on and off. When the battery is attached, a regulated 3.2 V voltage is normally input to the 8-bit microprocessor (IC301) by IC302, so that clock counting and key scanning is carried out even when the power switch is turned off, so that the camera can start up again. When the battery is removed, the 8-bit micro- processor operates in sleep mode using the backup lithum battery. At this time, the 8-bit microprocessor only carries out clock counting, and waits in standby for the battery to be attached again. When a switch is operated, the 8-bit microprocessor supplies power to the system as required. Both the PA ON signal from the ASIC and the P ON signal from the 8-bit microprocessor at pin (16) set to high, and then turns on the DC/DC converter. After this, low signal is output from pin (18) so that the ASIC is set to the reset condition. After, this pin set to high, and set to active condition. If the LCD monitor is on, the LCD ON 1 signal at pin (12) set to high, and the DC/DC converter for the LCD monitor is turned on. Once it is completed, the ASIC returns to the reset condition, all DC/DC converters are turned off and the power supply to the whole system is halted. ASIC, 8 bit LCD
