Low-voltage warning (ALARM VOLT )
if the receiver voltage falls below the set value, a low-voltage warning is generated by the transmitter's RF module in
the form of the "general alarm tone": a regular beeping at a rate of about one per second; alternatively the speech output
message "Receiver voltage".
Temperature warning (ALARM TEMP)
if the receiver temperature exceeds the set temperature threshold, a warning is generated by the transmitter's RF module
in the form of the "general alarm tone": a regular beeping at a rate of about one per second; alternatively the speech
output message "Receiver temperature".
Maximum altitude (Max. altitude)
at this point you can enter a maximum altitude, at which an alarm is triggered, either via the transmitter's RF module in
the form of the "general alarm tone": a regular beeping at a rate of about one per second; alternatively the speech output
message "Height". Note: the model's actual height is adopted as zero when the receiver is switched on; the indicated
height is therefore the altitude relative to the launch point.
Cycle time (PERIOD):
if your system is used exclusively with digital servos, you can set a cycle time (frame rate) of 10 ms at this point. If your
system includes some or all analogue servos, you should always select 20 ms, as many analogue servos cannot process
the higher frame rate, and may respond by "jittering" or "growling".
HoTT sum signal (SUMD)
if you activate the digital sum signal at channel 8, a sum signal containing eight channels is present at this socket, instead
of a servo signal. The HoTT receiver conigured as SUMD constantly generates a digital sum signal from 8 control signals
from the transmitter and makes this signal available at the appropriate servo socket, which is receiver-speciic.
At the time these instructions were revised, this type of signal is used by several of the latest electronic developments in
the area of lybarless systems, heavy-duty airborne power supplies, etc.
