1. The operation and range of your HPM Wireless Door Chime depends on location, temperature and
battery condition.
2. Try different locations in your home, ideally 1 metre from floor. Move Door Chime Receiver closer to
Bell Press Transmitter to improve operation.
3. Do not expose the Transmitter or Receiver to rain or immerse in water.
4. Avoid locations where the Bell Press Transmitter is exposed to direct summer sunlight.
5. Do not leave exhausted batteries in Door Chime Receiver or Bell Press Transmitter.
6. Clean only with a damp cloth and mild detergent. Do not use solvents.
7. Care should be taken when replacing Receiver batteries. Open casing carefully so as not to damage
the internal wiring.
Should your
Door Chime
Receiver activate
intermittently
for no reason, it
is possible that
the uncontrolled
activation may
be caused by
another unit
operating nearby
on the same
frequency coding.
The encoded
frequency of the
transmitter (Bell
Press Transmitter) and receiver (Door Chime Receiver) can be changed to avoid this problem.
First, turn the two devices so their backs are facing you. Using long nose pliers, place a jumper (small
black device included in pack with the adhesive ‘ foam pads’ or double-sided tape) on the same row of
pins on both devices. To change the preset channel place the jumpers on same row #. (See Fig 2.)
It is essential that the jumper positions are the same for both units. Test to ensure correct operation.

Door Chime Receiver
Step 1:
Depress tab on Door Chime Receiver to remove back cover plate.
Step 2:
Insert 3 x ‘C’ size alkaline batteries ensuring that the coil springs contact the negative (-) end
of each battery.
The Door Chime Receiver is fully portable and free-standing and can be placed anywhere in the house
(e.g., table, bookshelf, cupboard, mantelpiece, window sill, etc).
It can also be fixed temporarily or permanently to a wall as required.
BEFORE PERMANENTLY FIXING BELL PRESS AND DOOR CHIME RECEIVER IN PLACE, TEST
LOCATION OF BOTH UNITS TO ENSURE SATISFACTORY OPERATION.
The Door Chime Receiver has one slotted hang hole on the back. This hole will enable the Door Chime
Receiver to be hooked onto a screw and easily removed or relocated.
Bell Press Unit
Step 1:
Remove front plate cover by lifting bottom edge and sliding out.
Step 2:
Insert 12V battery (included in pack) ensuring the positive (+)
end of the battery is at the (+) in the battery compartment.
(See Fig 1.)
Step 3:
Replace front plate cover.
Step 4:
Press the Push Button to ensure that the red LED indicator
lamp lights, indicating that the battery is correctly installed.
Step 5:
Fix the Transmitter either directly to your front door or a
position close by using the self-adhesive foam mounting
pads supplied. The chosen mounting position should not be
exposed to direct sunlight or rain. The device can also be used
remotely.
IMPORTANT:
Do not mount the Bell Press Transmitter on metal or
near a metal door frame, security door, or in close proximity to any
metal outdoor furniture as the range of the unit will be substantially reduced.
The Bell Press Transmitter has one 12 volt battery (type 3LR50) included which should last about 850
days (in excess of 2 years) under normal operating conditions.
The Door Chime Receiver is powered by 3 x ‘C’ size batteries (not included). Alkaline batteries are
recommended for longer operating life, up to 180 days.
IMPORTANT:
Do not use rechargeable batteries, do not mix old and new batteries or different types.

PROBLEM
POSSIBLE CAUSE
SUGGESTED SOLUTION
The Door Chime is
intermittent when it
is activated or sounds
when not activated.
A similar door chime with the same
frequency is operated nearby.
Change the channel of your Door
Chime and Bell Press (refer to
Changing Operating Channels).
The tone selector is located in the Bell Press Transmitter. The two last pins (see Fig 2.) are the 2 possible
chime tones. To change tone simply remove jumper and fit on the last row of pins.
