User Manual

Particular attention should be paid to cord entrance and exit points.
Where installation involves an external radio aerial/antenna, the antenna should be located
away from power lines. Ensure that where applicable the antenna system is grounded, to
provide some protection against voltage surges and the build-up of static charges.
This equipment has been designed to conform to the relevant Radio and EMC performance
standards, but it may be necessary to take additional precautions during installation, to
ensure continued compliance.
Use only cables supplied, or suitably rated power cables and screened signaling cable.
Where quoted, do not exceed specified cable lengths and keep cable runs to a minimum,
especially on the outside of buildings.
Do not unnecessarily route wiring alongside cables from or through areas that are a source
of interference e.g. heavy plant and switch rooms, RF transmitter housings, without taking
suitable precautions to reduce EM interference coupling.
Where necessary, use additional protection e.g. armoured trunking, surge arrestors,
especially on the outside of buildings.
Where any interference problems are observed, it may be required to fit additional filtering
components such as ferrite absorbers, or in-line filters. If such action proves to be necessary,
contact either Multitone or their authorised agents.
Connection of Power Supplies
Use only power sources specified, or supplied by Multitone. The use of another device will
invalidate any declared conformity for this equipment, if as a result it ceases to conform to
those standards on which conformity is based.
The equipment should only be connected to a power supply as described in the operating
instructions, as marked on the equipment, or supplied by Multitone. Do not overload outlets
and extension cords, as this can result in fire, or electrical shock.
Where equipment has been provided with a three-wire grounding type plug, this plug will only
fit a grounding type power outlet. This is a safety feature and should not be defeated. If you
are unable to use a grounding outlet, contact your electrician.
Where equipment has been has been provided with a polarised line plug (one blade wider
than the other - US/Canada), this plug will only fit a power outlet one way. This is a safety
feature and should not be defeated. If you are unable to insert the plug fully, try reversing the
plug. If the plug still does not fit, contact your electrician to replace the obsolete outlet.
Servicing
This equipment contains non user-serviceable parts. All repairs to be undertaken by qualified
service personnel. In the case of a problem, please contact your service
representative/agent.
All the safety and operating instructions should be read before the equipment is connected
and operated and retained for future reference. All warnings marked on the equipment
should be strictly adhered to. No attempt should be made to remove any designated safety
covers, as these areas contain voltages of a sufficient magnitude to constitute a risk of
electric shock to personnel.
