General Note; Functions; Binding; Binding Multiple Receivers - GRAUPNER HOTT GR-32 Manual

Thank you for purchasing the Graupner HoTT 2.4 System Please read through this entire manual before
you attempt the installation and usage of your Graupner HoTT 2.4 System!
A hardware antenna diversity system always switches to the better antenna signal and for transmission
always uses the antenna that was last used for receiving. This ensures that the back channel data
are always sent via the better-positioned antenna. Without additional sensor systems, the parameters
receiver voltage and temperature, as well as signal strength are transmitted. Connector for one tele-
metry sensor and for the sum signal input or output. The receiver does have 6 power inputs for strong
servos.

1. GENERAL NOTE

When switching on or adjusting the radio control system it is essential to keep the transmitter aerial at
least 15 cm away from the receiver aerials at all times. If the transmitter aerial is too close to the receiver
aerials, the receiver will be overloaded, causing the green LED starts flashing. The transmitter responds
by emitting a beep once every second; the red LED also goes out. The radio control system is now in
Fail-Safe mode.
If this should occur, simply increase the distance between the aerials until the audible warning signal
ceases, and the red LED on the transmitter lights up again; at the same time the green LED on the
receiver should glow constantly.

2. FUNCTIONS

2.1. Binding

When you wish to use the Graupner HoTT 2.4 GHz receiver with a particular transmitter, the first step
must always be to "bind" the unit to "its" Graupner HoTT 2.4 GHz RF module (transmitter). This "binding"
procedure only needs to be carried out once for each combination of receiver and RF module. The units
supplied in the set are already bound to each other at the factory, i.e. the binding procedure described in
the following section only needs to be carried out when you wish to use an additional receiver. However,
it can also be repeated at any time if required, e.g. after changing transmitters. When binding is required,
this is the procedure:
• Switch the transmitter and receiver on.
• Locate the BIND / RANGE button on the back of the transmitter, and hold it pressed in while you
press and hold the SET button on the receiver. Both LEDs on the back of the transmitter now glow
constantly, and the red LED on the receiver flashes.
• If the red LED expires and the green LED on the receiver begins to glow permanently within about
ten seconds, this indicates that the binding process is complete. You can now release both buttons,
and your transmitter / receiver combination is ready for use.
• However, if the green LED on the receiver continues to flash for longer than ten seconds, then the
binding process has failed. If this should occur, repeat the whole procedure.
2.2. Binding" multiple receivers in one model
If required, it is also possible to bind multiple receivers to the transmitter for a particular model. The first
step is to bind each receiver individually using the procedure already described.
When the system is in use, the receiver which was bound last is the Master receiver (which is switched
