The CHQ-ADAPTOR is designed to allow the “Smart-Fix“ range of CHQ Modules to be
housed in existing enclosures originally designed for the first generation CHQ-OEM
Modules by modifying the ‘footprint’ of the unit.

When disassembling the "Smart-Fix“ CHQ Module in preparation for mounting onto the
Adaptor please be aware that the device features a printed circuit board (PCB) which
contains electro-static sensitive components. Observe precautions for handling these
components to avoid damage to the unit.

be lined up with their corresponding
holes on the PCB cover (see Fig 4


Push the two parts together until the
