Notes on chip component replacement
- Never reuse a disconnected chip component.
- Notice that the minus side of a tantalum capacitor may be dame

aged by heat.

Flexible Circuit Board Repairing
- Keep the temperature of the soldering iron around 270 C dur-

ing repairing.

- Do not touch the soldering iron on the same conductor of the

circuit board (within 3 tithes).

- Be careful not to apply force on the conductor when soldering

or unsoldering.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
