9. WHAT IS HoTT
OPERATION
HoTT stands for Hopping Sequence Telemetric
Technology, it is Graupner/SJ’s unique telemetry
technology in 2.4GHz signal protocol that supports
Bi directional data transmission gives user real-time
information on things like user model’s RPM,
Voltage, Temperature, User programmed warning,
and etc. The use of up to 75 channels ensures
extreme operating reliability and immunity to external
interference thanks to optimized frequency hopping
broad channel sequence.
Remove the battery cover and install the battery pack
ensuring the polarity of the battery connecter.
The included charger is designed to recharge your batteries at a rate of 150mA. Do not use
this charger for equipment other than Graupner/SJ transmitters that use 4-cell battery packs.
The charging plug polarity may not be the same and equipment damage can result. During the
charging operation, the charger’s temperature is slightly elevated. This is normal.
All Graupner/SJ charge jacks are center-pin negative. This is the opposite of many charg-
ers. Before using a charger make sure the connector is center-pin negative. This can be
done using a voltmeter. Also unlike conventional radio systems that use 8 cells to power the
transmitter, the mz-10 uses 4 cells. This is due to the electronics being more efcient. When
charging, be sure to use a charger designed for a 4-cell 4.8-volt battery pack when charging
the transmitter.
Leave the trainer switch to Normal position and turn on the transmitter.
The mz-10 is compatible with all current Graupner/SJ aircraft receivers (R Series)

Optional NiCd or NiMH 1.2-volt AA rechargeable 4-cell batteries can be used. A battery connecter
is on the inside of the transmitter for convenient recharging. Graupner/SJ offers rechargeable
NiCd, NiMH batteries, part number S22331.
