Emergency calls
The emergency services can be
contacted in the UK by dialling 999 or 112 which is valid in any country that is a member of the European community.
Please note
If your Synergy 2150 is connected to a switchboard/PBX, you may have to dial an access number before 999 to contact the emergency services. Some switchboards cannot dial out during a power failure.
The Synergy 2150 will not work when the power fails. Alternative arrangements should be made for access to emergency services.
Replacing the handset battery
After a time, you may find that the handset battery is running out of charge more quickly. This is a standard sign of wear and the battery will need replacing.

Do not immerse batteries in water or throw them into a fire, or dispose of them with ordinary domestic refuse.
