Before installing the ZXDSL 831/831B/831II/831BII ADSL equipment, you
must check the following items.
1 Electric safety
l Ensure that there are no inflammable, conductive or moist objects
around. Check whether the cables are aged and whether other
electrical appliances are placed stably.

ensure that these devices are positioned in a well ventilated
environment.
l The devices should be placed on a stable and flat plane.
l Never expose the equipment to direct sunshine, and never place it on a
PC case.
l Keep the equipment away from heat and water.
l Check whether power supply is available. The input voltage
fluctuation range must be less than 10%. The power plug should not
share one socket with a hair drier, iron or refrigerator.
1.2 Safety Cautions
l Read the user manual carefully before using the equipment.
l Note all Cautions in the user manual and product guide.
l Never use an accessory unbelonging to the equipment without prior
consent of the manufacture, because it may cause fire or product
damage.
