GETTING STARTED
General
To avoid interference, do not run cables parallel to
AC wiring, or near fluorescent lights or other high
magnetic or electrical fields. Interference from this
kind of sources causing equipment to be faulty or fail
working properly will automatically void warranty
conditions. Access to the interior of the equipment
shall be made by a Nera qualified technician only.
The equipment should preferably be installed by a
Nera SatCom approved Installation & Service Agent.
Warranty is not valid until the "Nera SatCom AS
Warranty Certificate" (at the back of the Registration
and Warranty Certificate booklet enclosed with the
equipment) is signed by the approved Installation &
Service Agent, and returned to Nera SatCom.
Grounding
Connection to all type of equipment meant for
operation together with Nera F33 should be done
while the unit is powered off. Peripheral equipment
using mains shall be connected to a grounded AC
power socket.
