Important Information
Safety precautions
Please read these precautions and the instructions on setting up and using the product thoroughly before using the device. Save this info sheet and do not give the device to third parties without it.
Privacy. Telephone calls are transmitted between the base station and the headset by radio waves, so there is a possibility that your wireless headset conversations could be intercepted by radio receiving equipment within range of the headset. For this reason, you should not think of wireless headset conversations as being as private as those on corded telephones.
Charger, power adapter, and headset with non-removable battery
CAUTIONS:
Use only the power converter (AC/DC adapter) delivered with the device. Other power power supplies may damage or even destroy it.

- UK: Ten Pao International Ltd., model no. S004LB0600045, or VTech Telecommunications Ltd., model no. VT04EUK06045
- The headset contains a non-removable, rechargeable Li-Ion battery, 3.8V 185mAh 0.7Wh, supplier GP Batteries, Ltd. Do not open the headset and attempt to replace the battery!
Placement of charger and cord, operation of USB stick and headset
- Warning: Install power adapter near the equipment and easily accessible.
- Avoid placing the device's cord where people may trip over them. Avoid placing the cord where it may be exposed to mechanical pressure as this may damage it. If the power supply cord or the plug is damaged, disconnect the device and contact qualified service personnel.
- The device is for indoor installation only. Not for outdoor installation!
- The operational temperature is between 0 °C to +40 °C (32 °F to +104 °F), humidity not exceeding 95% and non-condensing.
- Do not install product in rooms with high humidity (for example, in bathrooms, laundry rooms, damp basements). Do not immerse product in water and do not spill or pour liquids of any kind onto or into any parts of it. If the product comes in contact with any liquids, unplug any line or power cord immediately. Do not plug the product back in until it has dried thoroughly.
- Do not install product in surroundings at risk for explosions and do not use the handset in such surroundings (paint shops, for example). Do not use the headset if you smell gas or other potentially explosive fumes!
- Medical devices might be adversely affected. Please consider the technical ramifications when installing the devices in a doctor's office, for example.
- Warning: The headset contains a magnet and may attract small dangerous objects such as needles or pins. Please ensure before each use that no such objects are present.
- Potential TV interference. Some wireless headsets operate at frequencies that may cause interference to TVs and VCRs. To minimize or prevent such interference, do not place the base station of the wireless headset near or on top of a TV or VCR. If interference is experienced, moving the wireless headset farther away from the TV or VCR will often reduce or eliminate the interference.
If you have an implanted pacemaker
- Do not use if you have an implanted pacemaker unless the pacemaker manufacturer's directions expressly permit the use of devices emitting pulsating radio frequency signals. Always follow the manufacturer's directions!
- Recommended MINIMUM distance to the headset: 20 cm (7").
- Do not carry the headset in a breast pocket.
- Wear the headset on the ear opposite the medical device to minimize the potential for interference.
- Turn the headset off immediately if there is any reason to suspect that interference is taking place.
If you are wearing a hearing aid
Please note that the headset may cause an annoying background noise.
Additional safety information
Earbuds
DO NOT insert the earbuds into your ear canal.
Children, small children
- This headset is not intended for children under the age of 14, and can be dangerous and harmful to babies and younger children.
- Keep this headset, its parts and its package away from babies and children. The small parts of this headset can be lodged in a child's ears or nose or, if swallowed, in the child's windpipe, causing suffocation.
Operating environment
Remember to follow any special regulations in force in any area, and always switch off your device when its use is prohibited or when it may cause interference or danger. Use the device only in its normal operating positions. Do not place credit cards or other magnetic storage media near the device, because information stored on them may be erased.
Medical devices
Operation of any equipment emitting radio frequency signals may interfere with the functionality of inadequately shielded medical devices.
Consult a physician or the manufacturer of the medical device to determine if they are adequately shielded from external radio frequency (RF) energy or if you have any other questions concerning this topic. Switch off your device in health care facilities when signs posted in these areas instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.
Implanted medical devices
Manufacturers of medical devices recommend that a minimum distance should be maintained between a wireless device and an implanted medical device, such as pacemakers or cardioverter defibrillators, to avoid potential interference with the medical device. Persons who have such devices should:
• Always keep the wireless device more than 20 centimeters (7.8 inches) from the medical device when the wireless device is turned on.
- Not carry the wireless device in a breast pocket.
- Hold the wireless device to the ear opposite the medical device to minimize the potential for inter-ference.
- Turn the wireless device off immediately if there is any reason to suspect that interference is taking place.
- Read and follow the directions of the medical device's manufacturer.
If you have any questions about using your wireless device with an implanted medical device, consult your health care provider.
SELV (Safety Extra Low Voltage) Compliance
Safety status of Input/Output connections comply with SELV requirements.
Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Switch off the device at refuelling points such as near gas pumps at service stations. Observe restrictions on the use of radio equipment in fuel depots, storage, and distribution areas; chemical plants; or where blasting operations are in progress. Areas with a potentially explosive atmosphere are often but not always clearly marked. They include below deck on boats, chemical transfer or storage facilities, vehicles using liquefied petroleum gas, and areas where the air contains chemicals or particles such as grain dust or metal powders.
Sensitive Electronic Equipment
The current state of research concludes that operational DECT devices normally do not adversely affect electronic equipment. Nevertheless, you should take some precautions if you want to operate DECT devices in the immediate vicinity of such equipment like sensitive laboratory equipment. Always keep a minimum distance of 10 cm (3.94") to the equipment even when the phone is in standby.
Electrical Surges
We recommend the installment of an AC surge arrester in the AC outlet to which this device is connected to avoid damage to the equipment caused by local strikes of lightening or other electrical surges.
Important Battery Information

- Do not place or store the headset in the immediate vicinity of open fire or other heat sources.
- Leaving the battery in hot or cold places will reduce its capacity and lifetime. Charge batteries within an ambient temperature range of 0 °C to +40 °C (+32 °F to +104 °F). A device with a hot or cold battery may not work temporarily, even when the battery is fully charged.
- Store headset in a cool, dry place without corrosive gases.
