Thank you for purchasing this Cambridge Audio Incognito product. Incognito is a costeffective, modular based multi-room system using standard Cat-5/5e or Cat-6 cable to
distribute hi-fi quality sound around a home. Optionally, video can also be distributed using
co-axial cable and a VH10 video hub.
The LK10 in-wall learning keypad must be used with the Incognito KP10 A-BUS™ audio
keypad and LR10 learning remote.
The LK10 keypad clones learnt IR codes and macros from the LR10 remote which once
transferred allow the LK10 to be used to control your source equipment conveniently from
the wall.
The LK10 is fitted on the wall by fixing it into a standard double J-box electrician’s back-box
and double Decora™ style faceplate (not included) next to a KP10 keypad. All knock-outs in
the back-box should be removed to provide maximum ventilation. Care should be taken in
choosing a site for the LK10, always refer to the precautions in this guide.
Thank you for taking the time to read this manual, we do recommend you keep it for future
reference.
Matthew Bramble, Cambridge Audio Technical Director
and the LK10 design team.

LK10
ENGLISH
The LK10 is fitted on the wall by fixing it into a double USA-type J-Box (electrician’s backbox). All knock-outs in the back-box should be removed to provide maximum ventilation.
Where it is desired to fit a mains lighting switch etc next to a keypad, a barrier-box or two
single back-boxes must be used (bear in mind it is not preferable to fit the keypad next to a
light-switch particularly if the faceplate styles will differ). Only a qualified electrician should
attempt such installations.
Avoid fitting the LK10/KP10 where there is line of sight to another LK10/KP10. In such
situations both keypads may pick up the same commands from a remote control and it will
be difficult to control each zone independently.
Avoid fitting the LK10/KP10 where there is line of sight to the source equipment for the
system. In such situations the source equipment may pick up the same IR commands
directly as are picked up by the keypad and sent to the source equipment. This can
interfere with the remote operation of the source equipment.
Do not fit the keypad in areas directly lit by strong sunlight or where it will be strongly lit by
fluorescent tubes. These can be sources of infra-red energy which can interfere with the
remote control operation of the system. Some plasma televisions can radiate a lot of infrared energy and care should be taken if fitting a LK10/KP10 near a plasma screen
television. Avoid placing the LK10/KP10 near to dimmer switches or other items, which
generate a lot of electrical noise.
Safety precautions
Care should be taken when choosing the site for a LK10; the keypad must never be
installed in a back-box which also contains mains wiring or in areas of high humidity.
