● After the repair work, make a test run to check

whether there is any error and explain the notes on

use to the customer.

1. Notes on repair

WARNING

When performing disassembly repair, be sure to

stop operation and switch off the earth leakage

breaker.

Failure to do so may cause electric shock.

Be careful not to touch the charging unit when

performing a repair or a circuit inspection that

requires a power supply.

Switch off the earth leakage breaker of the unit

before repair work. Failure to do so may cause

electric shock.

Do not repair electrical parts with wet hands.

Doing so may cause electric shock.

Do not spray detergent spray or water on the

unit.

Doing so may cause electric shock or re due to

malfunction or electrical short circuit.

2. Notes on products after repair

WARNING

Be sure to repair the unit with parts that

are described in the service parts list of the

applicable model and use the appropriate tools.

In addition, never modify the product.

Doing so may cause electric shock, overheating

or re.

When moving the unit, be sure to install it securely.

Inadequate strength or incomplete installation

may cause a fall, electric shock, overheating or

re.

Do not damage or modify the power cord.

Doing so may cause electric shock or re.

Placing heavy objects on the power cord, heating

it, or pulling it, may cause damage.

3. Inspection items after repair

WARNING

Scratched or deteriorated power cords or lead

wires must be replaced. Also, do not connect the

power cord partway. Doing so may cause electric

shock, overheating or re.

CAUTION

Check that product mounting positions, wiring

conditions, and connection state such as

soldering, crimp terminal, and so on are normal.

Failure to do so may cause overheating, re or

electric shock.

Note

1. About noise malfunction

Since communication control is performed by pulse signal, it has the property that it is easily affected by external noise.

In normal use, there is no problem since this is taken into consideration on the circuit, but please note that an inuence may

occur depending on the installation state.

Places susceptible to noise Symptoms Measures

1. Area with strong radio waves in the

vicinity of a broadcasting station

2. Near to wireless station

3. Near to use of high-frequency sewing

machines or arc welding machines

4. Hospitals (such as X-ray rooms)

5. Near to plasma or liquid crystal

televisions

1. Stops in the middle of operation

2. The liquid crystal display ickers

Prevent noise from being received by

the signal wiring

↓

· Keep away from source

· Adopt shielded wire
