PRODUCT LIABILITY

WARNING

Fix the equipment. Do not put any object on PBX and Main Power; it might be danger- ous if the object should fall down.

When plugging off a plug, be sure to grip the plug and extract it. If you grip the code and extract it, it might cause a fire and an electric shock.

If a fault is considered as the lightening cause, ask the supplier.

Other than fulfilling the appropriate humidity and temperature, it is necessary to consid- er the maintenance operation and the all-time ventilation in non-loading operation dur- ing day-off and night. For example, when the height above floor is 1 m (3.281 feet), the temperature should be from 20 to 25 °C (68 to 77 °F ) and the humidity should be more or less 50 %.
