Removing And Installing The Rf Module - Multiplex ROYALevo 7 Manuel D'utilisation

!
Check regularly that the aerial makes sound
contact. Contact problems with telescopic aeri-
als reduce radiated power and therefore effec-
tive range, and reliable operation is no longer
guaranteed. If the aerial is bent, wobbly, or ex-
cessively free-moving due to wear, you must
replace it.
If the aerial is damaged, it can easily be slid out after
removing the case back, and withdrawn from the aerial
sleeve. Fit a replacement ROYALevo aerial, # 89 3002.
The plastic guide attached to the base of the aerial
should be fitted to the new aerial; an allen key is re-
quired to remove it from the old aerial.

Removing and installing the RF module

The two RF modules (HFM-4 and HFM-S) are not fitted
in protective housings. For this reason:
Avoid touching the main circuit board and its com-
ponents
Do not stress the main circuit board
Protect the RF module from mechanical strain
Observe the notes regarding electro-static dis-
charge ( 3.1.)
!
Do not change any settings
If you accidentally alter the settings of any compo-
nent on the RF module, or if a component is dam-
aged, send the module to a MULTIPLEX Service
Centre or our central Customer Service Dept. and
ask for it to be checked, repaired and re-calibrated.
Removing the RF module:
1. Switch off the transmitter!
2. Open the transmitter (
3. Place the transmitter face-down on a soft surface.
Take care not to damage the sticks and switches!
4. Grasp the RF module by all four corners using your
thumbs and index fingers, and withdraw it carefully
and steadily (see picture below). Keep it "square" to
its socket!
Installing the RF module:
Hold the RF module as described earlier. Ensure that the
module is engaged correctly on the contact pins. Care-
fully and steadily push it into place, again keeping it
"square" to the socket.
!
When changing the RF module take particular
care to avoid touching the electronic compo-
nents. If the module is to be stored outside the
transmitter, protect it from dirt and damp, and
don't subject it to shock loads or vibration.

ROYAL evo 7 - Instructions
Changing the transmitter crystal (HFM-4 only)
Switch the transmitter OFF and remove the RF module.
Pull the crystal out of the RF module by its plastic tag.
When fitting the new crystal take care not to strain it
mechanically, and avoid bending the contact pins.
Use only genuine MULTIPLEX transmitter crystals de-
signed for the frequency band of your RF module, oth-
erwise there is no guarantee that it will work reliably.
MULTIPLEX transmitter crystals feature a translucent
blue plastic sleeve and are marked with the code letter
"S" or "Tx".
!
Crystals are extremely delicate components,
vulnerable to shock and vibration, and they are
among the parts which are crucial to the safe
operation of your RC system. Please don't drop
them, subject them to mechanical stress (never
use force to insert them), and always store them
carefully.
