Operating Notes
Transmitter power supply
The
mx
-16iFS transmitter is fi tted as standard with a
high-capacity 8NH-2000 TX NiMH battery (Order No.
2498.8TX ) (type may differ). When delivered, the stand-
ard rechargeable battery is not charged.
When you are using the transmitter you can monitor
the battery voltage on the LCD screen. If the voltage of
the transmitter battery falls below a certain point, you
will hear an audible warning signal. The screen then
displays a message reminding you that the transmitter
battery needs to be recharged.

Always recharge the transmitter battery in good time.
When you see this message, cease operations immedi-
ately and recharge the transmitter battery.
Charging the transmitter battery
The rechargeable transmitter battery can be charged
via the charge socket fi tted to the right-hand side of the
case. Leave the battery inside the transmitter for charg-
ing, to avoid premature damage to the internal battery
socket.
The transmitter must be switched “OFF” for the whole
period of the charge process. Never switch on the
transmitter when it is still connected to the charger; even
a very brief interruption in the process can cause the
charge voltage to rise to the point where the transmitter
is immediately damaged. For this reason check carefully
that all connectors are secure, and are making really
good contact.
Polarity of the
mx
-16iFS charge socket
Commercially available battery charge leads produced
by other manufacturers are often made up with the op-
posite polarity. For this reason use genuine
GRAUPNER
charge leads exclusively.
Charging the transmitter battery using an automatic
charger
The transmitter is designed as standard for use with
automatic battery chargers. However, this requires care
on your part:
The transmitter charge socket is not protected
against short-circuit and / or reversed polarity. It
is therefore essential to use the correct procedure
when connecting the charge lead: fi rst connect the
banana plugs on the charge lead to the charger, and
only then connect the other end of the lead to the
transmitter charge socket. When the charge lead is
connected to the transmitter, never allow the bare
ends of the plugs to touch! To avoid damage to the
transmitter, the charge current must never exceed 1
A. If necessary, limit the current on the charger itself.
Charging the transmitter battery using a standard
charger
It is also possible to charge the transmitter battery
using a charger with no automatic termination (cut-off)
circuit. The basic rule in this case is to charge the bat-
tery for fourteen hours, assuming that it is
initially fl at .
The charge current should be one tenth of the capacity
printed on the battery. This means 200 mA for the stand-
ard transmitter battery. However, you are responsible for
terminating the charge process manually if you use a
standard charger …
Removing the transmitter battery
The fi rst step in removing the transmitter battery is to
open the battery compartment cover in the back of the
case. This is accomplished by pushing it in the direction
of the arrow; it can then be lifted off:
Disconnect the plug at the end of the
transmitter battery lead by pulling
carefully on the lead, or by engaging
a fi nger nail behind the lug on the
top of the connector. However, don’t
pull the plug down or up; keep it as
parallel as possible to the surface of
the transmitter.
Battery timer, bottom left corner of the screen
This timer displays the cumulative operating time of the
transmitter since the last time the transmitter battery
was charged.
This timer is automatically reset to “0:00” when the
transmitter detects that the voltage of the transmitter
battery is signifi cantly higher than the last time it was
switched on, e. g. as a result of a charge process.
