PROGRAMMING THE GENERAL RECEIVER SETTINGS:
The receiver can be programmed using a suitable HoTT transmitter or the SMART-BOX (Order No.
33700).
3.2 RECEIVER SET-UP MENU
The receiver set-up menu appears in the “Telemetry” menu
under SETTINGS / DISPLAYS; alternatively - if you are using a
SMART-BOX - under SETTING & DATAVIEW. The method of
accessing this menu is described in the operating instructions
supplied with your transmitter or the Smart-Box.
Low-voltage warning (ALARM VOLT): if the receiver voltage or the external voltage connected to
channel 5 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 height (Max. height) - Order No. 33577 with integral vario only: 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 (CYCLE): 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 6, a sum signal containing
eight channels is present at this socket, instead of a servo signal. The HoTT receiver configured 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-specific. At the time
these instructions were revised, this type of signal is used by several of the latest electronic
developments in the area of flybarless systems, heavy-duty airborne power supplies, etc.
WARNING: if you wish to use this facility, it is essential to observe the set-up information supplied
with the devices connected to the receiver, otherwise there is a risk that your model may be
