Installation instructions for the TS-150
Preparation
•
Identify possible sources of interference:
switch on a hearing instrument, an
inductive loop receiver or a field-strength meter and localise these sources. Any
equipment causing interfering buzzing in the hearing instrument should be
switched off or moved away where possible.
•
Signal sources:
typical sources are sound signals from TV sets, radios, mu-
sic equipment and microphones. Only one signal source at a time should be
switched on in addition to the microphone.
•
Placement:
the TS-150 should be mounted firmly on a wall. Avoid placement
closer than 1 m to TV sets and potential interference sources. The TS-150
should be mounted in an area with good air circulation and should not be
exposed to excessive heat from cookers and other electrical appliances.
•
The loop cable
should be run horizontally. It should be attached or glued
firmly along the skirting board or edge of the ceiling (see “Notes”, point 1)
around the room to be covered by the inductive loop system. The loop is laid
in a pattern and with a cable type that assures matched loading (see below).
•
Cable type and area:
the loop cable may be of the single or multi-wire type.
The thickness of the cable is selected for a total resistance of between 0.5 – 1
Ohm including the connecting cable (See ”Selection of loop cable”).
Apart from the usual installation tools, signal cables and loop cables, the
installer should be equipped with a field-strength meter and a telemagnetic
receiver with headphones (e.g. Companion).
Mounting
1. The loop cable is attached or glued along the skirting board or ceiling edge
around the area (room) to be covered. The loop cable is then connected to
LOOP OUTPUT (see next page).
2. The amplifier is mounted on a wall with the mounting material supplied (drill-
ing template, see centrefold).
3. The signal cables from the sound sources can be either plugged directly into
the phono or Scart contacts or connected to the screw contacts on the connec-
tion block.
