WARNING

Do not connect the telephone line cord to the phone socket until your handset is fully charged. This will prevent the risk of the phone being answered before the battery is charged. Answering the phone before the battery is fully charged may prevent it from reaching its optimum capacity.

Battery low warning

If the handset battery symbol is empty and you hear warning beeps, you will need to recharge your handset before you can use it.

Helpline

If you are experiencing difficulty, please call the BT On-Air Helpline on 0870 240 4682.

WARNING

Under no circumstances should non-rechargeable batteries be used. Only use the approved batteries. Using unapproved batteries will invalidate your guarantee and may damage the telephone.

Fully discharging the batteries at least

once a week will help them to last as long as possible. However, the charge capacity of rechargeable batteries will reduce with time as they wear out, so reducing the talk/standby time of the handset. Eventually they will need to be replaced. New batteries can be obtained from the Helpline on 0870 240 4682.

When the battery has been charged for at least

16hours the display will show the symbol; you can then connect the telephone line cord to the base.

Battery performance

Your handset is supplied with NiMH batteries. These need to be initially charged continuously for 16 hours to reach full charge.

Note that the battery charge icon does not indicate the correct level when the batteries are first installed. The batteries must first be fully charged.

To replace the handset battery

If you need to replace the handset battery, slide off the battery cover. Remove the old battery by disconnecting the small plug inside the battery compartment.

Connect the plug of the new battery.

Replace the battery cover.

SMS specifications

BT SMS, or British Telecommunications Short Message Service, is a messaging service that allows users to send and receive text messages via mobile networks. This service has become increasingly popular due to its ease of use, reliability, and the ability to communicate in real time. BT SMS integrates various technologies, making it a crucial tool for both personal and professional communication.

One of the main features of BT SMS is its reliability. The service operates on established mobile network infrastructure, ensuring messages are transmitted quickly and efficiently. Additionally, SMS is designed to deliver messages even when mobile data services are unavailable, making it an essential mode of communication in areas with limited connectivity.

Another significant characteristic of BT SMS is its wide compatibility. It can be used across various mobile devices, regardless of the operating system. This universality is further enhanced by the ability to communicate with different network providers, allowing users to send messages to anyone, anywhere, as long as they have a mobile phone.

BT SMS supports various multimedia messaging capabilities, such as sending images, videos, and emoji through MMS (Multimedia Messaging Service). This enriches the text communication experience, allowing users to convey emotions and visual information that plain text may not adequately express.

Security features are also integral to BT SMS. Messages are often encrypted during transmission, protecting users' privacy and ensuring that their conversations remain confidential. Additionally, users have the option to enable message delivery reports, which provide confirmation when a message is successfully delivered.

The technology behind BT SMS is based on a store-and-forward mechanism. When a message is sent, it is first stored in the network's SMS Center until it can be delivered to the recipient's device. This allows for smooth delivery even if the recipient's phone is switched off or out of coverage at the time the message is sent.

In conclusion, BT SMS remains an essential communication tool with its reliability, compatibility, multimedia capabilities, security features, and robust technology. Whether for personal interactions or professional engagements, BT SMS continues to evolve, catering to the needs of users in a fast-paced, digital world. Its simplicity and effectiveness ensure that it remains relevant in an era dominated by various messaging applications.
