Checking The Transmitter And Receiver Batteries; Capacity And Operating Time - GRAUPNER mz-24 Pro Programming Manual

• Otherwise, the transmitter may freeze
directly after being turned on, and you
will be unable to control the model.
The transmitter may only be turned
on again after it has been turned off
and the described procedure has been
correctly repeated.
• When operating towed models, main-
tain a minimum distance of approxi-
mately 50 cm between the participat-
ing receivers or their antennas. Using
the satellite receiver is an option. Oth-
erwise, malfunctions from the feed-
back channel are possible.

Checking the transmitter and receiver batteries

Stop operation and recharge the transmitter battery at
the latest when the transmitter battery is running low,
the message "Charge the battery!" appears in the
display, and an acoustic warning sounds.
Regularly check the battery charge, especially of the
receiver battery. Do not wait until the movements of
the rudder are noticeably slower. Replace dead bat-
teries in a timely manner.
Always follow the manufacturer's charging instruc-
tions, and charge the battery for the indicated time.
Do not charge the batteries without monitoring them.
Never attempt to charge dry batteries. An acute ex-
plosion hazard exists.
All batteries must be charged before each use. To
prevent short-circuits, first plug the banana plugs of
the charging cable into the charger (make sure the
poles are correct). Then plug in the charging cable
plugs into the sockets of the transmitter and receiver
battery.
18 Installation instructions
If you are not going to use your model for a while,
disconnect all power sources.
Never use rechargeable or replaceable batteries with
damaged, defective or different cell types; that is, a
mixture of old and new cells, or cells by a different
manufacturer. Combinations of old and new cells or
cells from different manufacturers.

Capacity and operating time

The following applies to all power sources: The capac-
ity decreases with each charge. At low temperatures,
the internal resistance increases while the capacity
decreases further. As a result, the battery's ability to
discharge and retain power is reduced.
Frequently charging and/or using battery care pro-
grams can also gradually reduce the capacity. Never-
theless, check the capacity of power sources at least
every 6 months, and replace them if their performance
is significantly low.
Only use original Graupner rechargeable batteries!
