Product Handling
Notice
If you do not use the product for a prolonged period, for safety reasons, be sure to disconnect the power adapter from its power
outlet and to disconnect the USB cable from the USB port, and to remove the dry cell batteries or nickel-hydride batteries.
Do not ride on the product. Families with small children should be particularly careful. The rider may topple over or break the
product, causing injury.
On rare occasions, the anti-slip rubber applied to the bottom of the product may discolor the surface that is exposed to it.
Be sure your ears are away from the speaker when powering the product on or off, or when connecting or disconnecting the USB
cable, handset cord or cell phone cable. High-volume sound from the speaker may harm human ears.
To avoid high-volume sound from the product's speaker or from the other party's, which may harm human ears, do not switch on
or off the product during a teleconference. Also, do not connect or disconnect a USB cable, handset cord, cell phone cable and
external microphone cable during a teleconference to avoid the same hazard.
Follow the instructions below to properly use dry cell batteries and nickel-hydride batteries.
• Dry cell batteries you may use are valid AA alkaline batteries.
• Hydride batteries you may use are AA nickel-hydride batteries.
• Do not use new dry cell batteries together with used ones; do not mix different types of dry cell batteries, or use dry cell
batteries together with nickel-hydride batteries.
• Replace exhausted batteries immediately.
• NTT Advanced Technology is not liable for any malfunction of the product due to liquid leaks from your dry cell batteries or

Product Installation
Caution
Do not place the product near electronics, audiovisual devices, office machines and other magnetized equipment, nor in locations
where electromagnetic rays are generated (e.g., microwave ovens, speakers, television sets, radios, fluorescent lamps, inverter air
conditioner and electromagnetic ovens).
• Influence by magnetism or electrostatic noise may increase noise or render telephone conversation impossible. (The use of a
microwave oven may have a particularly significant influence.)
• Locations near a television or radio may cause poor reception or distorted television images.
• If you experience significant noise due to the presence of a broadcasting or radio station nearby, try moving the product to a
different location.
Locations where hydrogen sulfide exists (hot springs) or locations with high salt concentrations (seashores) may shorten the life
of the product.

When re-POWERING the product after turning it off, wait at least five seconds before turning it on.
Do not drop the product or subject it to strong impact, as doing so may cause failure.
Do not wipe the product with wet cloth, benzene, thinner or alcohol, as doing so may discolor or disfigure it. Excessive dirt may be
wiped off with a moistened cloth and mild detergent, after which a dry, soft cloth should be used to clean the product.

The R-Talk 800EX is a product that does not easily enable a third party to intercept a call made using digital signals. A third
party can receive your calls intentionally or accidentally in an uncommon way, since radio waves are used for signal transmission.
Please consider this issue carefully.
