SAFETY AND CARE INSTRUCTIONS
Caring for your telephone
To ensure you receive the maximum benefit from using your telephone, please observe the following
guidelines.
• Do not use benzene, thinner, or similar cleaning agents to clean your ThermoDECT phone, as
these may cause permanent damage not covered by the warranty. Use a clean, damp cloth.
• Keep your ThermoDECT phone away from hot, humid conditions and direct sunlight.
• Do not attempt to repair the telephone yourself. Contact the retailer or an electrician if your
telephone requires servicing.
Safety precautions
Please observe the following safety precautions when setting up and using your ThermoDECT
telephone.
• Do not use your ThermoDECT phone in or near water. Using your telephone with wet hands,
while standing in water, or in wet conditions (such as in the rain) can damage the unit and cause
injury from electric shock.
• If the base unit falls into the water, do not attempt to retrieve it until you have unplugged the
power source. Pull the unit out by its cord. Never reach into the water to retrieve the unit.
• Never use your ThermoDECT telephone out-of-doors during a thunderstorm. Unplug the base
unit from the telephone line and power source when there are severe storms in your area.
Damage caused by lightening is not covered by the warranty.

Choosing a location for the base unit
When selecting a location for your base unit, observe the following guidelines:
• Choose a location that provides easy access to a 220-volt AC power source. Never try to
lengthen the power cord. Use an appropriate AC power cord for your local power supply.
• Choose a location that will allow the telephone cable to reach a telephone jack.You can use an
extension jack or cable if necessary.
• Place the base unit as high as possible to obtain the maximum radio frequency range with the
handset.You may need to try several locations – such as upstairs, or near a first-floor landing –
to find the best range. Solid structures such as walls and doors may reduce the signal strength.
• Do not place the base unit near the sink, bathtub, or shower.
• Do not place the base unit near objects that may cause radio interference, such as another
telephone, large metal objects such a mirror or filing cabinet, or electrical appliance such as an
electric stove, washing machine, microwave oven, television, and fluorescent lights.
• Do not place the unit near heat sources such as radiators or air ducts, or in a place subject to
direct sunlight.

USING MULTIPLE HANDSETS

Note: This ThermoDECT telephone is compatible with most major modern DECT (Digital Enhanced
Cordless Telecommunications) telephones. If you already have a DECT system, check to see if the
systems are complatible by registering a handset to both base units.
Managing multiple handset and base unit registrations
A base unit can carry a maximum of 5 handsets on its network.You can make intercom, 3-way, baby
monitor, and transfer calls between handsets that are registered to the same base unit, but not to
handsets that are registered to a different base unit. Consider the following example.
Example: The Harris household has seven members: Mum, Dad, Jill, Anna, Sam, Grandma H, and
Tom. Each person has their own handset.Because the family has more than five handsets, they own
two base units. The following diagram shows how the handsets are registered.
With this set-up, anyone in the household can make or answer telephone calls. Mum, Dad, Jill, Anna and
Sam can make transfer, 3-way intercom, and baby monitor calls to one another, but not with Grandma H or
Tom.This is because Grandma H and Tom are on a different sub-network , or base unit, than the others.
They can make these types of calls between themselves, but not with anyone not registered to base 2.
Thus, if Mum answers an incoming call
for Tom, and wishes to transfer it, she
must do one of the following:
1. GiveTom her handset.
2. Ask Tom to use one of the hand
sets registered to base 1, then
transfer the call to that handset
(for instructions, refer to pages
19-20).
3. Take the caller’s name and
number and askTom to call back.

More long term, Mum can cross-register up to 3 handsets from Base 1 with Base 2. That way, any of the
3 cross-registered handsets can fully interact with both sub-networks. The following diagram illustrates this
set-up:
1. There are 5 handsets registered
to each base unit. No more ad-
ditional handset can be added
unless one is removed.
2. Mum, Dad, and Sam can use
the call tranfer, 3-way
conference, intercom, and baby
monitor features with anyone in
the household.
3. Anyone in the household can
use these features with Mum,
Dad, and Sam.
4. Jill and Anna cannot use these
features withTom or Grandma H,
but they can with Mum, Dad, and
Sam.
5.Tom and Grandma H cannot use these features with Jill and Anna, but they can with Mum, Dad, Sam,
and one another
As you add handsets and additional base units to your ThermoDECT telephone, it is important to remember
the following concepts.
1. Each base unit can carry a maximum of 5 handsets, and keeps a record of which handsets have been
registered to it.
2. Each handset keeps a record of which base unit(s) it has been registered to. A handset can be cross-
registered to up to 4 base units.
3. You may need to reset the registrations as you reorganize your telephone system.There are several
types of registration procedures, as follows:
