Error messages

Every time you switch the transmitter on, the
ROYALevo7 checks the contents of its memory. If it de-
tects an error, the following error message will appear:
Memory Error
If this should happen, do not use the transmitter, and
do not make changes to any settings.
The ROYALevo DataManager PC back-up and update
program ( 23.1.) is capable of correcting many data
errors. To make use of this simply carry out a data back-
up procedure. The data error will be recognised by the
ROYALevo Data Manager:
If you confirm by clicking on "Yes", but the error mes-
sage occurs repeatedly, there is a serious data error. In
this case the cause is often a hardware defect (perhaps
caused by neglecting the battery charging instructions,
or using an unsuitable or faulty charger). The trans-
mitter must then be sent to a MULTIPLEX Service Centre
for checking and repair.
Important: please check the version of ROYALevo
DataManager you are using.
For the ROYALevo 7 a later version of the ROYALevo-
DataManager is required than is current at the time of
printing of these instructions (V1.06).

22.1. HFM-4 crystal RF module

# 4 5690 35 MHz A- and B-band
# 4 5691 40/41 MHz band
# 4 5697 36 MHz
#4 5692 72 MHz
Reasonably priced RF modules using conventional crys-
tal technology. Be sure to use genuine MULTIPLEX plug-
in crystals.
Important: which channels can be used?
Regulations concerning the use of radio-controlled
models vary from country to country. Please make en-
quiries to establish which RF module you should use,
and which channels are approved for the region in
which you wish to fly your models.

22.2. Channel-Check module for HFM-4
crystal RF module
# 7 5164 35MHz A- and B-band (also for 36MHz)
# 7 5165 40/41MHz band
The Channel-Check module is simply plugged into the
HFM-4 crystal RF module, and is easy to
install at any time. The Channel-Check
module requires a receiver crystal (MUL-
TIPLEX single-conversion crystal) whose
channel / frequency is the same as the
transmitter crystal you are using. When
you switch the transmitter on, the mod-
ule checks whether the transmission
channel is in use, and only switches the
RF module on if it is vacant. In this way it
guards against frequency clashes and makes an impor-
tant contribution to safety in model sport.
Retro-fitting the module
1. Switch off and open the transmitter
2. Remove the HFM-4 RF module
3. Plug the receiver crystal into the

Channel-Check module

4. Plug the Channel-Check module
into the RF module
5. Re-install the RF module
Operation
1. Extend the transmitter aerial to full length
2. Switch on the transmitter
3. The RF status LED flashes:
the channel is free (no guarantee), the RF module
is immediately activated, and the transmitter is
ready to use. "No guarantee" means that the module
may not be able to detect distant transmitters
(approx. > 300 m) because of the influence of en-
vironmental conditions and the local terrain. How-
ever, if the model should fly close to such a transmit-
ter, there is then a risk of interference due to a chan-
nel clash.
4. RF status LED glows constantly
The screen also displays the following message for
two seconds: !Attention! No RF
If Channel-Check finds the channel to be in use
when switched on, you must switch the transmitter
off again before you can use it. Check whether your
channel is already in use by another modeller (in-
cluding transmitters a long way away!). If this is not
the case, the problem may be a transmitter in the
immediate vicinity on an adjacent channel, momen-
tary interference on the channel when you switched
on, etc. Before you switch on again, walk a little way
away from other transmitters, then try again.

22.3. HFM-S Synthesizer RF module

# 4 5693 35 MHz A- and B-band
# 4 5694 40/41 MHz band
# 4 5696 36 MHz
# 4 5695 72 MHz
RF modules exploiting modern Synthesizer technology.
The transmission channel can be selected quickly and
conveniently in the channel set-up menu. No plug-in
crystals are required at the transmitter.
