presence of radio interference, ask your dealer for

preliminary environmental measurement. In install-

ing new radio equipment after the system has been

installed as well, request a preliminary verification

of freedom from radio interference. If interference

is detected after the system is installed, they may

not be corrected.

・This product features built-in radio equipment

that operates on the entire band of 2.4 to 2.4835

GHz. Bands in which mobile stations are identi-

fied can be avoided. The product supports the

FH-SS modulation method and an interfering dis-

tance of 80m. It is labeled with a mark to desig-

nate these characteristics as shown at right.

Operating Instructions and Maintenance

Cordless terminals are designed to heighten radio output automatically as the separation

between the Bluetooth® cradle and Bluetooth® handset widens, thereby maintaining a satis-

factory state of communication.

Heightened radio output could cause radio interference to neighboring equipment. In this

occurs, keep the Bluetooth® cradle farther apart from the neighboring equipment.

If the Bluetooth® cradle and Bluetooth® handset get

dirty, wipe their surfaces with a soft, dry cloth.

If they are heavily soiled, wipe them with a diluted

solution of a kitchen detergent and then wipe them

off with a dry cloth.

Never use organic solvents, such as alcohol, ben-

zine and thinner, for cleaning; these chemicals

could damage the surfaces of the telephone.

Also, avoid using a chemical duster.

Tips on Radio Transmission

The working frequency band of this device is shared by industrial, scientific and medical

equipment, such as microwave ovens, premises radio stations that are typically used in

manufacturing lines at plants for mobile identification (radio stations that require licensing)

and specified low-power radio stations (license-free radio stations).

• Before using this device, check that premises radio stations for mobile identification and

specified low-power radio stations are not used nearby.

• If any case of radio interference arises from a premises radio station used for mobile

identification, discontinue radio transmission from this device immediately and contact

your dealer for advice on how to take action for avoiding the interference.

• Further, if any case of radio interference arises from a specified low-power radio station

used for mobile identification or any troubles develop, contact your dealer.

Operating Instructions and Maintenance

Keep the charging terminals of the Bluetooth® cra-

dle and Bluetooth® handset always clean. Wipe dust

off the charging terminals with a dry cotton swab or

the like at least once a month or rub them with a

cotton swab or the like impregnated with alcohol.

Because cordless terminals use radio transmission between their Bluetooth® cradle and Blue-

tooth® handset, they may take about 15 seconds after the line cord/LAN cable is instead into

the Bluetooth® cradle before calls can be made between the Bluetooth® cradle and Bluetooth®

handset.

If the Bluetooth® handset goes off- hook or the FNC/Conference or TALK key is pressed in

the meantime, the error tone “pi-pi-pi-pi” may sound without a wireless (line) connection

being established, but this is not a fault.

Charging Terminals

In cleaning the charging terminals, be sure not to:

• Touch the terminals with hands directly

• Short-circuit the terminals.
