Power Supply; Binding; Receiver Reset - GRAUPNER GR-12L HoTT Manual

Power supply

In principle, a battery can be connected to any free socket. By V- or
Y-cable also with any remote control component. If the power sup-
ply is provided by more than one battery, it is important to ensure
that the batteries have the same nominal voltage and rated capacity.
It is not allowed to connect different battery types or rechargeable
batteries with too different charge states to the receiver, as short-
circuit-like effects can occur. For safety reasons, voltage stabilizers
such as PRX-5A receiver power supplies (No. 4136) should be con-
nected between batteries and receiver.
Attention
When selecting and connecting a power supply, be aware that
although the operating range of the receiver ranges from 3.6 to 8.4
V. However, practically all of the previously marketed servos, speed
controllers, gyros, etc. as well as many which are offered today have
a permissible operating voltage range of 4.8 to 6 V.

Binding

To establish a connection with the transmitter, the Graupner HoTT
receiver must first be "bound" to at least one model memory in "its"
Graupner HoTT transmitter. This process is generally called "bind-
ing".
Binding step-by-step
1. Prepare the transmitter to be bound according to its instructions
for binding.
2. Switch on the receiver power supply.
The LED of a GR-12L HoTT receiver lights up red.
3. Press and hold the SET button on the receiver until the LED starts
to flash for about 3 seconds after approx. 3 seconds.
During this time lapse, the receiver is in bind mode.
4. Within this time lapse start the transmitter-side binding accord-
ing to the instructions of the transmitter.
5. If the red LED of the GR-12L HoTT receiver goes out, the binding
process has been completed successfully.
Your transmitter/receiver combination is ready for operation.

If the red LED of the GR-12L HoTT lights up again constantly, the
"Binding" has failed. Change the positions of the associated
antennas and try the entire procedure again.
To reset the receiver, press and hold its SET button while turning on
the power to the receiver:
If the reset was triggered with the transmitter switched off or with
an unbound receiver, the red LED of the receiver GR-12L HoTT starts
to flash after about 3 seconds. The button will now be released.
If the reset is performed with a not bound receiver, you can then
start a binding process at any time.
If a reset has already been performed on an already-bound receiver
and the associated model memory is active in the switched-on trans-
mitter, then the red LED of the receiver GR-12L HoTT should go out
and thus signal a correct connection to the transmitter. Otherwise
the process has to be repeated.
Notes
• Through a RESET ALL of the settings in the receiver are brought
to the factory settings with the exception of the HoTT synchro-
nization information!
• If a reset is performed accidentally, all of these settings that
were made using the "Telemetry" menu in the receiver should
be restored.
• Resetting is particularly recommendable when you want to
switch a receiver to a different model. This makes it easy to keep
settings which do not match from being transferred.
