MR164 Keypad
Operating
Instructions
Congratulations and thank you for choosing this
Knoll product. The MR164 keypads can control the
GSZ67 controller-amplifiers. They are very easy-to-
use giving you top quality sound available in up to
six or more rooms.
The MR164 is available with two LCD colors, yellow-
green with black lettering and blue with white
lettering (model MR164b). Both versions are
available with Decora™ style bezel plates in white,
almond, black or ivory colors.
The music system consists of:
1. Rooms with stereo speakers, a MR164 keypad or a
third party whole house controller and possibly a
remote control.
2. One or more GSZ67 controller-amplifiers.
3. Stereo source components such as tuners, CD
players, satellite dish receivers, cassette decks, and
other components.
While the MR164 evolved after years of research, its
use is straightforward and direct. Some rooms may
have more than one pair of speakers and one or two
MR164 keypads or possibly even no keypad.
The music system is controlled by the MR164
keypads, RB12 or universal remote, the source
components and possibly a whole home controller.
The source components are controlled by their
individual remote controls by aiming the remote
control at the keypad or infrared receiver and
pressing the appropriate remote control button.
Please read about the GSZ67 with the manual
shipped with that product.
MR164 Keypad Operation
The MR164 keypad is relatively easy to operate and
within a short period of time should be very intuitive.
Please ensure that keys are not pressed too fast as
the controller or keypad may be confused. If this
happens reset the system powering it off and then
on again.
