33700 SMART-BOX - Graupner HoTT 2.4

                                                                             06

Signal quallity (S-QUA):

 shows the signal quality in % 

Receive performance (S-dBm): 

the receive performance is sent “live” to the SMART-BOX via the receiver’s 

downlink channel. Note: the receive performance is shown as a negative value, i.e. a value approaching 
zero is the maximum (= best reception); the lower the value falls, the worse the receive performance.
This value is particularly important during the range-check procedure carried out before 

fl

 ying the model.

Please read the corresponding section in the RC system instructions relating to range-checking.
Carry out a range-check before every 

fl

 ight, simulating all servo movements which will occur in 

fl

 ight: the 

range must be at least 50 m on the ground when the transmitter is set to range-check mode; to guarantee 
safe 

fl

 ying, the value displayed under S-dBm in the DATAVIEW display should be at least -80 dBm. If the 

value is lower (e.g. -85 dBm) you should not even consider 

fl

 ying your model: check the receiver installation 

and the power supply systems in your model and radio control system.
When operating your model this value should not fall below -90 dBm. If it does, you should reduce the dis-
tance between yourself and the model. However, under normal circumstances the 

audible range warning 

(see below)

 will be triggered before the value falls to this level, in order to ensure safe operations.

Signal strenght (S-STR)

: indicates the signal strenght in %.

An audible range warning

 (continuous beeping at one-second intervals) is always emitted as soon as the 

receiver signal in the downlink channel falls to the pre-set threshold. Since the transmitter has a much higher 
transmitting power than the receiver, it is still possible to operate the model safely, but in the interests of 
security you should always reduce the distance to the model until the audible warning stops.

Receiver temperature (R-TEMP): 

it is important that the temperature of your receiver always stays within 

the approved range under all 

fl

 ight conditions (ideally between 10 and 55°C; please refer to your RC system 

instructions).
The limit values for receiver temperature which trigger a warning can be set in the RX SERVO TEST display 
under ALARM TEMP+ (50 – 80°C) and ALARM TEMP- (-20 – +10°C).
If the receiver temperature rises above the maximum value or falls below the minimum, the unit generates an 
audible warning (continuous beeping). At the same time all the Smartbox receiver displays show a 

fl

 ashing 

“TEMP.E” at top right, and the parameter R-TEM is shown in inverse form in the receiver data display (RX 
DATAVIEW).

Data packets (L PACK TIME): 

indicates the duration of signal loss of the longest data packet during trans-

mission from transmitter to receiver, stated in msec. In practice this equates to the longest period which the 
RC system has spent in fail-safe mode.

Operating voltage (R-VOLT): 

it is essential to monitor the operating voltage of the receiver constantly. If it 

is too low, you must never launch your model or continue 

fl

 ying it.

The receiver low voltage warning can be adjusted in the RX SERVO TEST display under ALARM VOLT; the 
available range is 3.0 to 6.0 Volt. If battery voltage falls to the threshold level, an audible signal (continuous 
beeping) is emitted, and “VOLT.E” 

fl

 ashes at top right in all the Smartbox receiver displays. At the same time 

the parameter R-VOLT is shown in inverse form in the receiver data display (RX DATAVIEW).

Minimum operating voltage (L.R-VOLT): 

displays the lowest receiver operating voltage since the last time 

the receiver was switched on. If this voltage differs signi

fi

 cantly from the actual operating voltage R-VOLT, it 

is likely that the servos are placing an excessive load on the receiver battery, resulting in voltage collapses. 
If this should occur, you should consider 

fi

 tting a larger or more robust receiver battery in order to obtain 

maximum operating security.

Telemetry sensor 1 / 2 (SENSOR 1 / SENSOR 2): 

if these optional sensors are connected, their data 

(Voltage / Volt and temperature / °C) is displayed live on the screen.
