Never install telephone wiring during a lightning storm.2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnectedat the network interface.4. Use caution when installing or modifying telephone lines.Installation PrecautionsThis Hybrid IP-PBX is designed for wall mounting only, and should be installed in a location where it isaccessible for inspections and maintenance.To prevent malfunction, noise, or discolouration, avoid installing the system in the following locations:1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0 to 40 )2. Areas where sulfuric gases may be present, such as near thermal springs.3. Areas where shocks or vibrations are frequent or strong.4. High-dust areas, or places the system may come into contact with water or oil.5. Near devices that generate high frequencies, such as sewing machines or electric welders.6. On or near computers, telexes, or other office equipment, as well as microwave ovens or airconditioners. (It is preferable not to install the system in the same room as the above equipment.)7. Within 1.8 m of radios and televisions. (Both the Hybrid IP-PBX and PTs should be at least 1.8 m awayfrom such devices).8. Locations where other objects will obstruct the area around the Hybrid IP-PBX. Be especially carefulto leave at least 20 cm of space above and 10 cm to the sides of the Hybrid IP-PBX for ventilation.9. Do not stack up the optional service cards. To avoid damage to the optional service cards, always usethe extension bolts.Wiring PrecautionsBe sure to follow these instructions when wiring the unit:1. Do not run unshielded telephone cables near AC power cables, computer cables, AC power sources,etc. When running cables near other noise-generating devices or cables, use shielded telephonecables or shield the telephone cables with metal tubing.2. If cables are run on the floor, use protectors to prevent the cables from being stepped on. Avoid runningcables under carpets.3. Avoid using the same AC outlet for computers, telexes, and other office equipment, as noise generatedby such equipment may hamper system performance or interrupt the system.˚C ˚C
