Frequently Asked Questions - Studio 3500 Trio British Telecom
How do I set up the British Telecom Studio 3500 Trio?
Connect the base station to the phone line and power supply. Insert the rechargeable batteries into the handsets and place them on the base to charge for at least 12 hours before first use. Then follow the on-screen instructions to register handsets.
How many handsets can be added to the base?
The Studio 3500 Trio supports up to 4 additional handsets, but it comes with 2 extra handsets (total 3). You can purchase additional handsets separately.
What type of battery does the handset use?
Each handset uses a Ni-MH AAA rechargeable battery rated at 1.2V and 600 mAh. Replacements can be bought from British Telecom or compatible suppliers.
How long does the battery last?
The battery typically provides up to 10 hours of talk time and 100 hours of standby time. Actual battery life may vary depending on usage and signal conditions.
Can I use the phone during a power outage?
The handsets are cordless and rely on the base station's power. During a power cut, the phone will not work unless a backup battery is connected to the base (not supplied). Corded phones do not have this limitation.

Indoor range is approximately 50 meters; outdoor range can reach 300 meters. Range may be affected by walls and interference.
How do I store contacts in the phonebook?
Press the Menu button, select Phonebook, then Add Entry. Enter the name and number using the keypad, then confirm. You can store up to 100 entries.
Can I block unwanted calls?
This model does not have built-in call blocking. However, you can use your network provider's call blocking services or a separate call blocker device.
What should I do if the handset says 'No Base'?
Ensure the base station is powered and the handset is within range. Try re-registering the handset: place it on the base, press and hold the page button on the base for 5 seconds, then follow handset menu instructions.
How do I clean the phone?
Use a soft, dry cloth to wipe the handset and base. Do not use water, solvents, or abrasive cleaners as they may damage the device.
