Byron SX-34 Installation Manual

The wirefree door chime kit consists of three separate units:

1. Converter unit (Transmitter)

2. Door chime unit (Receiver)

3. Wired Brass Bell Push
When the converter is activated, it sends a wirefree

signal to activate the door chime. As the operating
range is up to 100 metres (320 ft. approx.), you can
mount or take the door chime virtually anywhere in
the home, workshop, office or garden and use the
system as a short-range personal pager. However,
the operating range of the wirefree signal will be
reduced if the signal is transmitted through a number
of walls or ceilings. Metal, and UPVC doorframes will
also reduce the operating range.

Locate the keyhole slot on the back of the chime unit, over the screw. Then use
the second hole located at the bottom half of the converter as a template, mark
the fixing position for the unit. Drill hole and fit wall plug and secure the converter
unit with the screw (self-tapping N3 x 16mm screws - included) in position.
Important: Mounting the converter unit on UPVC doorframes or metal sufaces

will reduce the broadcasting range seriously.

1) Westminster - 8 notes

2) Ding-Dong - Repeat

3) Telephone Ring

4) Circus Theme

Melody Selection

The melody selector is located inside the converter unit. It is a small button on the top left
corner of battery compartment marked with “S”. Press the switch once, the melody will change
to the next one on the list, there are total 8 melodies for selection. The converter is pre-set to
“Westminster” therefore, if no change is required, it should not be adjusted.

5) Banjo on my knee

6) Twinkle, Twinkle

7) It’s a small world

8) Dog Barking

Door Chime unit

1. Slide open the battery compartment door on the back of the unit.
Insert 2 x 1.5 volt alkaline batteries (“AA”, UM3, R6 size - not
included), ensuring the battery’s polarity matches the internal
markings. Close the battery door and the chime unit is now
ready to use.

2. Alternatively the unit can be powered by an A/C-D/C 9 volt
300mA adaptor (Byron model SX-36 - not included).
No batteries are required for the chime unit using this method.

PLEASE MAKE SURE YOU REMOVE ANY BATTERIES
FROM THE UNIT WHEN USING THE PLUG ADAPTOR
TO POWER THE CHIME UNIT.

3. This chime unit can be completely portable, or fixed in one place. There is a specially
designed hanging arm available at the back of the chime for ease of portability.

Channel Selection

The unit comes from the factory on a pre-set radio frequency channel. However, should your
door chime activate intermittently for no reason at all, it is possible that a similar unit is
operating nearby on the same frequency digital code. The encoded frequency of the
Converter (transmitter) and Door Chime (receiver) can be changed to avoid this problem.

1. Converter: Remove the back of the case by pushing in the tab on the bottom with a small,
flat screwdriver.
Door Chime Unit: Slide open the battery compartment.

2. There is 4 position dip switch marked 1,2,3,4. Use an
insulated tool to alter the dip switch levers to the “On” or
“Off” position, which can be altered to achieve a total of
sixteen (16) possible digital code.

3. Select any combination ensuring it is set to the same
code on both converter and door chime units. E.g.
If the 1 & 2 dipswitches are down in your converter,
then the 1 & 2 dipswitches must be down in your
chime unit.

4. Test to ensure correct operation before final installation.
