Opening the Unit
To open the case, undo the 4 security screws around the edge of the unit. These
screws are normally Torx type with a centre security pin.
The front section is fitted over the rear section and can be gently lifted clear.
Take care when separating the 2 sections – there are 4 cable sets between the 2 halves:
5. Induction loop audio (2 conductors)
6. DC power (2 conductors)
7. Earth cable
8. Ethernet cable.
These cables are deliberately short, but will allow the front section to sit to the left of the rear
for set-up purposes if required.

Installation method
The Help Point is intended for vertical installation to a solid wall or suitable post as detailed
below.
1. Ensure the Help Point has been configured for the network as described in section
3.2.
2. Choose a suitable location for the Help Point, bearing in mind the weight of the unit,
and that the operating button(s) should normally be in the range 1200 – 1400mm
from the ground for ease of access by people in wheelchairs.
3. Mark the wall or surface with fixing centres as shown above. If necessary use the
rear section to help mark the centres. Do not use the rear section as a drilling
template.
