Congratulations on the purchase of your new JA COB
JENSEN
TM
Doorbell.
The doorbell is designed in Denmark by Jacob Jensen, whose products have gained
international recognition for their original, simple and classic design. Jacob Jensen
has received around 100 prizes from around the world and has 19 products included
in the Design Study Collection and The Design Collection of The Museum of Modern
Art in New Y ork.
The cordless doorbell consists of a bell push and a chime offering five dif ferent,
specially composed high sound quality tunes. Listen to Jacob Jensen knocking at
the door , a classic town hall bell, a contemporary or oriental inspired tune or a low-
frequency tune, designed especially for the hard-of-hearing. The sound level can
be set to high/low or off. Lights on both the chime and the bell push will illuminate
when the bell is rung or the batteries need changing.
The doorbell is supplied with one bell push and batteries are included. One single
chime can operate with an unlimited number of bell pushes and extra bell pushes
are available separately . The chime can be free standing or wall mounted, either
using screws or a JA COB
JENSEN

Mounting plate. The bell push can be mounted
with screws or double-sided tape. The maximum working distance between the
chime and the bell push is up to 150 meters though positioning either unit on
or near metal structures or reinforced pvc doors or door frames may block the
transmission or reduce the transmission range.
Activating / changing the batteries
Install the batteries according to the polarity symbols marked in the battery
compartment. With new product batteries to the chime are included in the gift box.
Batteries are installed in the bell push, but here the plastic strip must be removed in
the battery compartment - under the lid mounted with four screws ( see p. 25).
Note: Instead of batteries, a plug-in mains adaptor , type 6V DC minimum 400mA,
available from electronics stores, can be connected to the chime (see page 24).
Insert the adaptor into the external socket in the chime’ s battery compartment and
plug into the wall outlet.
Set the code
Y our JA COB
JENSEN
TM
cordless Doorbell has a coding system to ensure that there
is no interference to or from any nearby cordless product. The chime and the bell
push(es) need to have identical codes to recognise each other . Open the battery
compartment on both units and set the 4 keys (each has two positions) to identical
patterns to set up the code.
NB: A code has been pre-set. If a clear signal is obtained there is no need to change
this code.
Set the light
The lights on both the chime and the bell push will illuminate to indicate a ring.
Y ou can turn the light ON/OFF on the chime using the switch in the battery
compartment.
Light signals
Chime when someone is ringing: 2 flashes–pause–2 flashes etc.
Chime at low battery: flash–long pause–flash-long pause etc.
bell push when pressing the button: long flash
bell push at low battery: flash–long pause–flash-long pause etc.
Select tune
The doorbell offers you five dif ferent tunes. If you connect more than one bell push
it may be convenient to assign a different tune to each one, so that you can identify
which doorbell is ringing.
1) Classic town hall bell chime.
2) Contemporary lounge-inspired tune.
3) Oriental-inspired tune.
4) Low-frequency tune – suitable for the hard-of-hearing.
5) Jacob Jensen knocking at an old, wooden door .
The Door bell is pre-set to tune no. 5. Change the tune by using the switch in the
battery compartment of the bell push.
Note: Only one tune (or light) can be activated at a time. Once the bell has been
pressed, further presses will be ignored until the tune has been finished.
V olume
Set the volume to high/low/OFF by using the switch in the battery compartment of
the chime.
Reset
The RESET key in the battery compartment is used for resetting the system. If there is
any malfunction (such as no sound from the chime, try pressing the RESET button to
make the unit ready to receive or transmit a signal again.
Mounting
Before mounting the chime and the bell push(es) ensure that a clear signal can
be obtained. Place the units next to each other , activate or install the batteries,
press the bell push and listen to the tune. Move the units to the desired locations
and check that the signal is still operating. If not, remove the object causing the
interference or find a new location. Note that other cordless products, strengthened
PVC doors, door frames, steel constructions and building materials may block the
signal or cause interference.
Chime
The chime can be free standing or wall mounted using the enclosed screws and
plugs (see mounting template in the back of this manual), or with a JA COB
JENSEN
TM
Mounting plate.
Bell push
The bell push is mounted using the enclosed mounting plate, screws and plugs
(see p. 25). When the mounting plate is fixed, slide down the bell push until a
"click" is heard. For changing the battery , release the bottom lock by pressing the
hook towards you (use a small and flat screwdriver to handle the lock). Remain with
the lock in released position while sliding the bell push upwards.
Note: The bell push is not to be mounted on metal door frames.

Doorbell unit so
you can enjoy using it for many years.
1. Keep the chime dry at all times. If it becomes wet, wipe it dry immediately . Liquids
can contain minerals that might corrode the electronic circuits.
Note: provided the casing is intact the bell push is weatherproof.
2. Use and store the units only under normal temperatures. T emperature extremes
can shorten the life of electronic components, damage batteries and distort or
melt plastic parts.
3. Handle the units gently and with care. If they are dropped, circuit boards can be
damaged, resulting in malfunction.
4. Keep the units free from dust and dirt to avoid the premature wear of parts.
5. Clean the units by wiping a soft cloth. Do not use abrasive chemicals, cleaning
solvents or strong detergents to clean the units.
6. Use only fresh batteries of the required size and type. Always remove old or weak
batteries as they might leak chemicals that will damage the product.
