4. Once the transmitter and receiver have detected each other,
both units automatically switch over to regular transmit /
receive mode (Normal operations  13.):
=> The LED in the transmitter's LED-button flashes
approximately every two seconds.

Note: the binding process usually only takes a few seconds.

ANGE CHECKING
Regular range checks are very important - even when using a
2.4 GHz system - in order to ensure reliable operation of the
radio control system, and to give you a chance to detect sources
of interference in good time. This applies in particular:
 Before the use of new or changed components, or existing
components in a new or modified arrangement.
 Before re-using radio control system components which were
previously involved in a crash or a hard landing.
 If you have encountered problems on a previous flight.
Important:
 Always ask a second person to help you with your range
check, so that one of you can secure and observe the model.
 The range check should only be carried out if there are no
other transmitters switched on at the same time.
Preparations, carrying out the range check:
1. Select "range check" mode on the Graupner mc-32
transmitter with 2.4 GHz M-LINK technology as follows:
 Switch the transmitter ON.
 Within four seconds of switching the transmitter ON,
press and hold the LED push-button until the LED itself
glows continuously.
2. Switch the M-LINK receiver ON.
3. Carry out the range check as described in the operating
instructions supplied with your M-LINK receiver.
4. When you have completed the range check, switch OFF
the Graupner mc-32 transmitter with M-LINK
technology, and then ON again, in order to switch back
to normal transmit mode with full range!
!
Note: after switching the transmitter OFF, wait a few
seconds before switching it back ON again!
!
Caution: selecting "Range check" mode reduces the
transmitter's output power. The transmitter emits an
audible signal every ten seconds or so to warn you of
this.
Never attempt to fly a model with the transmitter set to
reduced output (range check mode)!

ORMAL OPERATIONS
This is the procedure for operating the Graupner mc-32
transmitter with 2.4 GHz M-LINK technology in normal transmit
mode (normal operations):
1. Switch the transmitter ON:
=> The LED in the LED-button flashes once approximately
every two seconds.
2. Switch the M-LINK receiver ON.
The M-LINK system is now ready for use.
This is the procedure for switching OFF the 2.4 GHz M-LINK RC
system:
1. Switch the M-LINK receiver OFF.

2. Switch the transmitter OFF.

The 2.4 GHz ISM band provides a means of transmitting data
from the model to the transmitter. If you are using a telemetry-
capable M-LINK receiver, your Graupner transmitter with 2.4 GHz
M-LINK technology warns you when the receiver battery voltage
falls to a low level via the RF module's integral buzzer.
For more information on this subject please refer to the opera-
ting instructions supplied with your telemetry-capable M-LINK
receiver.
If the MULTIPLEX Telemetry-Display (# 4 5182) is also used,
the screen shows the connection quality (LQI = Link Quality
Indication) as well as the voltage of the receiver power supply.
The Telemetry-Display can also show additional telemetry data.
Examples of this include current, voltage, altitude and speed
values - depending on the sensors connected to the system.
The Telemetry-Display is capable of displaying a maximum of
sixteen telemetry values.
Visual and audible warnings are generated by the Telemetry-
Display. The warning sounds are produced either through the
integral loudspeaker with volume control, or the earpiece, which
is an optional accessory. The same applies to the audible
sounds generated by the Vario sensor.
