To minimize or prevent such interference, the base of the cordless telephone should not be placed near or on top of a TV, microwave oven or VCR. If such interference continues, move the cordless telephone farther away from these appliances. Certain other communication devices may also use the 2.4GHz frequency for communication and, if not set properly, these devices may interfere with your new telephone. Typical devices that may use the 2.4GH frequency include wireless audio/video senders, wireless computer networks and multi-handset cordless telephone systems. CHOOSING BASE UNIT LOCATION When selecting a location for your base unit

(which records and displays the indoor tempera-

ture), please observe the following guidelines:

Choose a location that provides easy access to a 120-volt AC power source. Choose a location that will allow the telephone cable to reach a telephone jack. (You can use an extension cable if necessary). Place the base unit as high as possible to get N E a better radio frequency range with the handset. You may need to try several locations such as upstairs, or near a first-

floor landing to find the best range. Solid structures, such as walls and doors, may reduce the signal strength. Do not place the base unit near a sink, bathtub or shower. Do not place the base unit near large metal objects or electronic appliances that may cause radio interference. Some of these include: mirrors, filing cabinets, electric stoves, washing machines, microwave ovens, televisions, fluorescent lights or other telephones. Do not place the unit near heat sources, such as radiators or air ducts, or in a place subject to direct sunlight. CONNECTING THE BASE UNIT To connect the base unit:

1. Plug the AC adaptor into the power jack on the back of the base, and then plug the other end into an electrical outlet. Plug the telephone line cord into the telephone line jack on the back of the base unit, and then plug the other end into a modular phone jack. 2. NOTE : The adaptor is shipped with the product.

CAUSES OF POOR RECEPTION Aluminum siding Foil backing on insulation 18 TW339 manual_Eng 5.p65 21 3/5/05, 9:23 AM N E Heating ducts and other metal construction shielding radio signals You are too close to appliances, such as microwaves, stoves or computers Atmospheric conditions, such as strong storms Base unit is installed in the basement or lower floor of the house Base unit is plugged into an AC outlet with other electronic devices Baby monitor is using the same frequency. Handset battery is low You are out of the base units transmission range MAINTENANCE AND CARE This product is designed to give you years of service if handled properly. Please observe the following guidelines:

Avoid putting the phone near heating appliances and devices that generate electrical noise, such as motors or fluorescent lamps. Do not expose your telephone to direct sunlight or moisture. Do not tamper with the internal components. Do not mix new and old batteries, or batteries of different types. Avoid dropping the phone and other rough treatment. Clean the phone with a soft cloth, but never use a strong cleaning agent or abrasive powder. This will damage the finish. Remove the batteries if storing this product for a long period of time. Periodically clean the charge contacts on the handset and base unit with a clean pencil eraser. Do not make any changes or modifications to this product. Retain the original packaging in case you need to ship the phone at a later date. MAXIMIZE BATTERY PERFORMANCE The freedom that your cordless telephone can offer is fully dependent on the performance of the rechargeable battery in the handset. To maximize the battery performance, follow these guidelines:

19 Charge it for a full 15 continuous hours Before initial use of your new battery, charge it for 15 continuous hours. The proper initial charging is very important to maximize the battery performance. Keep the contacts clean You can never fully recharge the battery if the contacts are dirty. Clean all the contacts

(two at the bottom of handset and two in the base cradle) periodically using a pencil eraser. Do not replace the handset in the base unit cradle after each call Repeated short charging creates a memory effect in the battery. Once a rechargeable battery acquires this short memory, it sends a CHARGE BATTERY signal even when it is almost fully charged. The battery then needs to be charged frequently. To avoid this, leave the handset away from the cradle until it really needs recharging. Refresh battery If your battery seems to need recharging more often than usual, it may have lost part of its charging capacity because of premature recharges. To bring back its full capacity, try refreshing the battery:

1. First discharge the battery by leaving the handset in TALK mode until the battery low indicator turns on.

(Disconnect the base unit from the telephone line, so that your line is not busy all the time). Then charge it for 15 continuous hours. Repeat the above once more. 2. 3. SPECIFICATIONS You phone operates on a 2.4GHz ISM digital Worldwide Digital Cordless Telecommunication
