17NC4 set-up tool
Introduction
The NC4 set-up tool is a battery operated device
that is used to provide the operator with a visual
indication of the signal strength at the NC4
receiver unit. The signal strength is viewed by the
operator on a numerical display. The higher the
number, the greater is the signal received at the
receiver unit.
The set-up tool is placed over either the
transmitter or receiver unit and is rotated so that
the display can be easily viewed by the operator.
Placing the tool over an NC4 unit activates the
numerical display. Removing the tool causes the
display to power-off.
NOTE: The numerical display provides only an
indication of the signal strength. If a true reading
of signal strength is required, a voltmeter must
be connected to the appropriate connector pins
on the NCi-4 interface.
The set-up tool can be used on fixed and
separate NC4 systems.

Battery specification
The set-up tool requires one ½ AA size battery,
rated at between 3.3 V and 3.6 V. It is important
to ensure that the battery is supplied in standard
(button) form. Batteries that are described as
tagged have additional connection tag features
fitted to the terminal and are not suitable.
