Division 22 Performance characteristicsF1F2

159 The Vehicle Unit shall be fully operational in the temperature range - 20 ^o C to 70 ^o C, and the motion sensor in the temperature range - 40 ^o C to 135 ^o C. Data memory content shall be preserved at temperatures down to - 40 ^o C.

160 The recording equipment shall be fully operational in the humidity range 10 % to 90 %.

161 The recording equipment shall be protected against over-voltage, inversion of its power supply polarity, and short circuits.

161a F3Motion sensors shall either:

• react to a magnetic field which disturbs vehicle motion detection. In such circumstances, the vehicle unit will record and store a sensor fault (Requirement 070) or,

have a sensing element that is protected from, or immune to, magnetic fields.

162 The recording equipment shall conform to Commission Directive 95/54/EC of 31 October 1995 ^f1 adapting to technical progress Council Directive 72/245/EEC ^f2 , related to electromagnetic compatibility, and shall be protected against electrostatic discharges and transients.
