Do not push any objects into the openings of the
unit. Doing so can cause fire or electric shock by
shorting out internal components.

unit (other than a cordless type), during an electrical
storm. There may be a remote risk of electric shock
from lightning.
Equipment connected to the Voice port must be
located in the same building as the unit.
Be sure nothing rests on the unit's system cables and
that the cables are not located where they can be
stepped on and cause damage to the unit.
Keep the unit away from radiators and heat sources.
Allow 25mm (1 inch) around the unit to provide
adequate air circulation.
Install the unit in a clean area that is free from dust
or extreme temperatures.

unit or stacked with other OfficeConnect units. Do
not place anything else on top of the unit's case.

rear panel of the unit, to allow for cable access.
This product ostensibly complies with the
electro-magnetic compatibility (EMC) requirements
of EN 55022 Class A and EN 50082 (susceptibility).
However, to fully comply with Class B of EN55022 the
following prerequisites should be observed;
the WAN port must be attached to a screened
digital cable.
the ISDN cable must be used in conjunction with
a three turn ferrite.
This unit contains a lithium battery which is
attached to a microchip on the printed circuit board.
The defective battery must be disposed of safely
in-line with the manufacturers instructions.
Interconnecting directly, or by way of other
apparatus, to ports complying with SELV
requirements may produce hazardous conditions on
the network. Advice should be sought from a
competent engineer before such a connection is
made.
