This symbol is intended to alert the user to
the presence of uninsulated “dangerous
voltage” within the product’s enclosure
that may be of sufficient magnitude to
constitute a risk of electric shock to
persons.
This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
For the customers in the U.S.A.
You are cautioned that any changes or modifications not
expressly approved in this manual could void your
authority to operate this equipment.
WARNING FOR THE CUSTOMERS IN THE UNITED
KINGDOM
THIS APPARATUS MUST BE EARTHED.
IMPORTANT
The wires in this mains lead are coloured in accordance with
the following code:
Green-and-yellow: Earth
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured markings
identifying the terminals in your plug proceed as follows:
The wire which is coloured green-and-yellow must be
connected to the terminal in the plug which is marked by the
letter E or by the safety earth symbol + or coloured green or
green-and-yellow.
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal which is marked with the letter L or coloured red.

SAFETY RELATED COMPONENT WARNING
Components identified by shading and !| marked on the
schematic diagrams and parts list are critical to safe
operation. Replace these components with SONY parts
whose part numbers appear as shown in this manual or
in supplements published by SONY.

SAFETY CHECK-OUT
After correcting the original service problem, perform
the following safety checks before releasing the set to
the customer:
Check the metal] trim, ‘metallized’ knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any ex-
posed metal part having a return to chassis, must not
exceed 0.5 mA (S00 microampers). Leakage current
can be measured by any one of three methods.
1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers’ instructions to use these instru-
ments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for
this job.
3. Measuring the voltage drop across a resistor by
means of a VOM or battery-operated AC volt-
meter. The “limit” indication is 0.75V, so
analog meters must have an accurate low-
voltage scalé. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are
suitable. (See Fig. A)

the limits for a digital device pursuant to Subpart B of Part
15 of FCC Rules.

Section 1 Operation
1-1-1 Features
The BC-1WD/1WDCE is a battery charger capable of continuous
charging, into which any four NP-1/1A/1B battery packs can be
inserted simultaneously.
The BC-1WD/1WDCE is equipped with the following features.
Up to four battery packs can be inserted
Up to four NP-1/1A/1B battery packs can be inserted and charged in
order. More than four battery packs can be charged continuously by
removing the fully charged battery packs and replacing them with
discharged ones.
Compact and lightweight
The BC-1WD/1WDCE is compact, lightweight, and easy to carry.
Automatic refresh function
If a battery pack with remaining capacity is charged repeatedly, the
storage capacity of the battery may be reduced due to memory effect
(phenomena by which the remaining battery capacity is memorized).
To prevent against this memory effect, an “auto refresh function” is
provided to fully discharge a battery pack automatically before
charging.
Diagnostics functions
The BC-1WD/1WDCE has functions to check for abnormalities in the
connected battery packs. A red and green lamp will alternately flash
when a battery pack cannot be normally charged indicating an
abnormal condition.
Life judgement function
The available capacity of the battery is indicated. This criterion is
used to determine the life of the battery pack.
Fully charged battery skip function
When a fully charged battery pack is inserted into the BC-1WD/
1WDCE, the battery is neither charged nor discharged, and the
indication “Charging End” will appear on the display.

1-1-2 Charging System
1. Operation
The BC-1WD/1WDCE begins discharging once the POWER switch is
turned ON. It continues to give a booster charge until the voltage drop
of —AV (see the figures below), which occurs near the end of charging,
is detected. Trickle charging (charging at a slow rate to normally
maintain the battery in a fully charged condition and to protect against
self discharge) will be done after all of the inserted batteries have been
charged. Trickle charging automatically stops after 24 hours of
continuation. Further, the charging status varies, as seen in the
diagrams below, according to whether you are in the auto refresh
mode or the refresh cancellation mode.

@ LIFE button and display
Press this button when desiring to determine the
life of the battery pack. This function works only
in regard to the battery pack in insertion section 4.
After inserting a battery pack into section 4, press
this button and the indication “OP” will appear on
the display. Subsequently, the results of the
available battery capacity measured will appear on
the display.
© REFRESH OFF button
Press this button and it will light up and charging
will begin immediately without automatic refresh
discharging. Press this button to alternate between
the auto refresh mode (button OFF) and the refresh
OFF mode (button ON). After all of the battery
packs inserted in sections | through 4 have been
charged once, this button automatically goes out
and returns the charger to the auto refresh mode.

One of the following conditions
exists:
¢ The battery voltage has not

voltage within a specified
period after commencement
of charging.
¢ The end of charging in the
-AV charge control system
has not been detected within
a specified period.
¢ Discharging when refreshing
did not end within a specified
period.
In such cases, try recharging
the battery pack two or three
times. If the same condition
persists, the battery pack may
be defective and should be
replaced.
© Ground terminal
Connect to a ground wire when necessary.
@ ACIN connector
Used to connect the unit to an AC outlet using
the supplied AC power cord.
@ Plug holder
Secures the AC power cord so that it will not
come loose from the unit.

1-3-1 Precautions
e Use the BC-1WD/1WDCE in surroundings with temperatures at 0°C
to 40°C (32°F to 104°F). Charging at low temperatures is difficult,
so it is recommended that the battery packs be charged at between
20°C to 30°C (68°F to 86°F).
e Avoid using or storing the BC-1 WD/1WDCE in places susceptible
to dust or corrosive gases.
e Avoid using or storing the BC-1 WD/1WDCE in places subject to
direct sunlight.
e Do not cover the ventilation holes.
