Operating Instructions and Maintenance
Use the antenna of the Bluetooth ® cradle in an
upright position.
The antenna would be broken or bent if it is given
undue force.
Cordless terminals may not work or may be
affected by interference if they are used near a
broadcasting station or near sources of intense radio
transmission, such as ham radio and CB radio.
Because radio equipment might be disabled in the
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.
