RX-ALARM
The default low voltage value of receiver is automatically set 4V by default, and small
adjustments are also supported. When the transmitter voltage is lower than the value set, T8FB
will make D sound to warn.
EXT-ALARM
To return the model voltage, RadioLink receivers of telemetry functions R8XM, R8FG, R7FG or R8F
should be used. small adjustments are also supported. When the model voltage goes lower than
the set value, T8FB will make D sound to warn. We suggest that 7.4V set for 2S lithium battery,
11.1V set for 3S lithium battery, 14.8V set for 4S lithium battery.
RSSI-ALARM
The default signal strength alarm value of the T8FB is -100dBm. You can set a reasonable value
according to the actual situation to prevent the model from losing control due to weak signal.
When the RSSI goes lower than value you set, T8FB will make D sound to warn.
The best RSSI-ALM is depends on the control range test at your flying area. For example, you
have tested the control distance of your T8FB is 2000 meters at your flying area, and the RSSI
shows -86dBm at this time, then you can set the RSSI alarm data is -86dBm.
(The EXT-Alarm and RSSI-Alarm only can be set on the mobile phone APP.)
