7 Appendix

7.1 Infrared lens

7.1.1 Liquids

Use one of these liquids:

• A commercial lens cleaning liquid with more than 30% isopropyl alcohol.

• 96% ethyl alcohol (C

OH).

7.1.2 Equipment

Cotton wool

CAUTION

If you use a lens cleaning cloth it must be dry. Do not use a lens cleaning cloth with the liquids that are

given in section 7.1.1 above. These liquids can cause material on the lens cleaning cloth to become

loose. This material can have an unwanted effect on the surface of the lens.

7.1.3 Procedure

Follow this procedure:

1. Soak the cotton wool in the liquid.

2. Twist the cotton wool to remove excess liquid.

3. Clean the lens one time only and discard the cotton wool.

WARNING

Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on con-

tainers before you use a liquid: the liquids can be dangerous.

CAUTION

• Be careful when you clean the infrared lens. The lens has a delicate anti-reflective coating.

• Do not clean the infrared lens too vigorously. This can damage the anti-reflective coating.

7.2 Infrared detector

7.2.1 General

Even small amounts of dust on the infrared detector can result in major blemishes in the

image. To remove any dust from the detector, follow the procedure below.

Note

• This section only applies to cameras where removing the lens exposes the infrared

detector.

• In some cases the dust cannot be removed by following this procedure: the infrared

detector must be cleaned mechanically. This mechanical cleaning must be carried

out by an authorized service partner.

CAUTION

In Step 2 below, do not use pressurized air from pneumatic air circuits in a workshop, etc., as this air

usually contains oil mist to lubricate pneumatic tools.

7.2.2 Procedure

Follow this procedure:

1. Remove the lens from the camera.

2. Use pressurized air from a compressed air canister to blow off the dust.
