9. Changing the Transmitter Channel and Group ID
■ Changing the Transmitter Channel
The LX-7120(G) is a transmitter of PLL synthesizer type, and its transmitter
channel can be programmed. It can be set up with an arbitrary channel among
the channels assigned by the Telemetry Laws (according to each country).
For details of the setting change, contact your local Fukuda Denshi service
representative.
WARNING
 If the transmitter channel is changed, follow the instruction by the
person in charge of the radio telemetry channel in your facility.
Mismanagement may result in a serious accident, such as interference
and mixing up patients.
 Replace promptly the new channel label if the transmitter channel has
been changed.
■ Changing the Group ID
The LX-7120(G) transmits its group ID, which it belongs to, to prevent
interference with neighboring hospital's transmitter.
The receiving monitor checks whether the incoming group ID is the same as
the programmed one that the receiving monitor has. There are 64 group codes
available. The default setting is “00”.
The transmitter group ID can be changed if there is interference with a
neighboring hospital's transmitter.
For details of the setting change, contact your local Fukuda Denshi service
representative.
CAUTION
Possible causes of interference other than radio telemetry from neighboring
hospital's transmitter, are the proximity of mobile phone, amateur radio
station, radio taxi, and illegal citizens band, which may be a cause of
interference. In such a case, the situation should be carefully observed to
find the cause of interference.
