- Test mode (using spectrum analyzer)
1. Cautions
If there is a spectrum analyzer supporting 2.4 GHz at the service site, confirmation of
transmission carrier becomes possible.
Since CD-BTB100 cannot operate singly, the main set with IP-BUS control is required.
Carrier existence is checked by removing the product case and applying the probe onto
the "ANT" land of the base unit.
Since it is done by probe connection, the level cannot be confirmed accurately.
2. Function outline
Simple operation check on Bluetooth is executed in test mode using a spectrum analyzer
supporting 2.4 GHz.
