Important
To use ‘Caller ID’ (display caller), this service has to be activated on your
phone line. Normally you need a separate subscription from your telephone
company to activate this function. If you don’t have the Caller ID function on
your phoneline, the incoming telephone numbers will NOT be shown on the
display of your telephone.
Importante
Para poder usar la función “Identificación de llamadas,este servicio tiene que
estar dado de alta en su línea telefónica. Normalmente es necesario abonarse
a dicho serviciopara que la compañía telefónica active esta función. Si su
línea telefónica no dispone de la funciónIdentificación de llamadas, la panta-
lla del aparato no mostrará los números de teléfono de las llamadas entrantes.
Importante
Para utilizar a função "ID Chamador" (visualizar Chamador), este serviço
terá de ser activado na sua linha telefónica. Normalmente necessita de sub-
screver este serviço, à parte, com o seu operador de telecomunicações, para
poder activar esta função. Se não tiver contratado este serviço a função ID do
Chamador não estará disponível e por isso os números de telefone das cha-
madas entrantes não aparecerão no seu telefone.

• Only use the charger plug supplied. Do not use other chargers as this
may damage the battery cells.
• Only insert rechargeable batteries of the same type. Never use ordinary,
non-rechargeable batteries. Insert rechargeable batteries so they
connect to the right poles (indicated in the battery compartment of the
handset).
• Do not touch the charger and plug contacts with sharp or metal objects.
• The operations of some medical devices may be affected.
• The handset may cause an unpleasant buzzing sound in hearing aids.

1.5m away from a water source. Keep water away from the handset.
• Do not use the telephone in environments where there is a risk of
explosions.

environment-friendly manner.
• As this telephone cannot be used in case of a power cut, you should use
a mains-independent telephone for emergency calls, e.g. a mobile

When the battery is empty, the handset no longer carries out operations.
When a battery is completely empty and you have put the handset on the
base unit for a short period of time, the battery symbol will appear to be
fully charged, but this is actually not the case. The battery capacity will
decrease rapidly. We advise you to put the handset on the base unit for 12
hours so it can be recharged completely.
When you are in the middle of a conversation and the battery is almost
empty, the handset will emit a warning signal. Place the handset on the
base unit to charge.
