Safety Notes
which allows you to set the charge current accurately,
then the battery should always be recharged using the
“normal” charge rate of 1/10C; see the example stated
above.
Wherever possible, transmitter batteries should
always be recharged at the 1/10C rate, in order to
avoid differences in cell states. The charge current
must never exceed the maximum permissible value
stated in the transmitter instructions.
Fast charging
If your battery charger includes the facility to adjust •
the Delta Peak charge cut-off voltage, set this value
to 5 mV per cell. However, most chargers are set to
a fi xed cut-off value of 15 … 20 mV per cell, which
makes them suitable for use with both NiCd and
NiMH batteries. If you are not sure about this, please
refer to the operating instructions supplied with your
charger, or ask at your local model shop whether
your charger is also suitable for Ni-MH packs. If in
any doubt, charge your batteries at half the stated
maximum charge current.
Discharging
All rechargeable batteries sold by Graupner and GM-
Racing are suitable for a maximum continuous current
load of 6C … 13C, according to battery type (refer to the
manufacturer’s specifi cation!). The higher the continuous
current load, the shorter the batteries’ useful life.
Use your battery until its performance falls off, or until •
the low voltage warning is triggered.
Caution:
When stored for a long period, the cell voltage should
not be allowed to fall below 1.2 V. This means that
you may have to recharge the battery before sto-
ring it.
Refl ex charging and charge / discharge (cycle) •
programs shorten the effective life of batteries unne-
cessarily, and are only suitable for checking battery
quality or “reviving” relatively old cells. It also makes
no sense to charge / discharge a battery before using
it - unless you simply wish to check its quality.
Disposal of exhausted dry and rechargeable batte-
ries
The German Battery Order places a legal requirement
on every consumer to return all used and exhausted
dry cells and rechargeable batteries. It is prohibited to
dispose of these items in the ordinary domestic waste.
At no charge to the user, old dry and rechargeable
batteries can be surrendered at local authority collec-
tion points, Graupner retail outlets, and any other shop
where dry and rechargeable batteries of the same type
are sold. You can also send batteries supplied by us to
the following address - with adequate pre-paid postage
- for disposal:
Graupner GmbH & Co. KG
Service: Gebrauchte Batterien (Used batteries)
Henriettenstr. 94 - 96
D-73230 Kirchheim unter Teck
You can make an important contribution to environmen-
tal protection in this way.
Caution:
Damaged batteries may require special packaging befo-
re despatch, as some contain highly toxic materials!!!!!

Graupner HoTT Smart-Box
Order No. 33700
A vast range of different functions combined in a single device: that’s
what destines the SMART-BOX to be your intelligent companion in
future. Whether you want to display telemetry data in real time, or
enter changes to your HoTT system, the large-area screen with 8 x 21
characters makes the task simple. The fl exible Smart-Box includes an
integral buzzer for generating audible signals and warnings for even
greater fl exibility and practicality.
The installation set supplied makes it easy to mount the unit on the
support bars of hand-held transmitters, allowing you to position it in
such a way that you can read off telemetry data in real time while you
control your model.
The user-update facility ensures that the SMART-BOX is always up-to-
date, and provides a route for expanded functions in future.
