8-716-106-196 issue a (10/03) UK
TRANSMITTER LOCATION
1Locate flat bladed screwdriver into
slots and twist to lift top of transmitter
(A) away from baseplate (B).
2Make sure that the batteries (C) are
correctly fitted to the transmitter (A)
3Position the transmitter as close to
the main living area as possible on
an inside wall, approx. 1.5m (5') above
the floor within max. signal range of
the appliance receiver.
Keep the transmitter away from:
light and heat sources
enclosures and curtains
direct draughts, including fans, air
vents, windows and doors
damp and condensation
4Press and hold button (D) down on
the receiver for approx. 2 seconds
until the LED (E) flashes twice and
stays on
Release button, the receiver will now
search for a signal for up to 2 minutes
The LED (E) on the receiver will flash
twice within 200ms when a radio link
has been established
Repeat procedure until a link has
been established.

securing points (C) and remove
baseplate (B)
2Drill holes, where marked, 30mm
deep using a 6mm diameter drill bit
3Push one wall plug (D) into each hole
4Reposition baseplate (B), check level
and secure with screws (E)
5Align outer edge and internal lugs
(F) of transmitter to baseplate (B)
