-Reception RF power in dBm
-Relative power graph
-Measured frequency
-« BAT » icon indicating battery level.
It is not advised to wait too long before recharging batteries.
You can increase battery lifetime by charging before « BAT » level is in red zone.
Receiver autonomy is approximately 4 hours. Charging must be performed with supplied charger only. Charging process is
controlled by a microcontroller, and can last up to 5hours.
When connecting charger to mains, red LED will blink 3 times for 3 seconds, then will blink every 30 seconds. When battery is
charged, LED will stay off.
It is recommended to charge battery when receiver is not in use...
Technology :
08-02-48 receiver use double frequency conversion, and a narrowband quartz filter.
Frequency bandwidth around tuned frequency is +/- 3.5KHz. It is important to check RF generator frequency, to avoid
measurement errors. Power measurement dynamic is -105dBm to -35dBm, depending on noise figure and on surrounding RF
emissions. In order to check lowest available level, disconnect antenna from receiver, and note displayed level.
DO NOT CONNECT RF SIGNAL WITH P>0dBm ON INPUT CONNECTOR ! (15dBm will destroy the receiver)
