Transmitter power supply
The mz-18 HoTT transmitter comes standard with a
rechargeable NiMH battery with 2000 mAh capacity, and
the mz-24 HoTT transmitter comes standard with a
1s2p lithium-ion battery with 4000 mAh capacity (subject
to modifi cation).
The standard battery installed in the
transmitter is uncharged upon delivery.
The transmitter battery voltage should be monitored in
the LCD display during operation. Once the adjustable
voltage in the "battery warning threshold" is reached in
the "Etc.Set" submenu of the system menu, page 202,
a standard 4.8 V (NiMH) for the mz-18 HoTT transmitter
and 3.6 V (lith.) for the mz-24 HoTT transmitter, a
warning beep sounds, and the following window
appears in the display:

General operating instructions
mz-18 and mz-24 HoTT transmitters
Note:
•
Make sure that the correct battery type has
been set in the submenu "Etc.Set" of the
system menu, page 202!
• In a special calibration menu that can be opened by
touching the voltage display in the basic display of
the transmitter using a fi nger or the provided stylus,
the real displayed voltage can be fi ne-tuned (see
"Battery warning" on page 202).
The rechargeable NiMh battery of the mz-18 HoTT
transmitter or the 1s2p lithium-ion battery of the mz-24
HoTT transmitter may be charged as described below
using the charging socket on the rear labelled CHARGE
with the provided plug-in charger:
The charging socket comes standard with a protective
diode that protects against polarity reversal. Original
Graupner automatic chargers recognize the battery
charge. Note the setting instructions of the charger
which is used.
Polarity of the mz charging socket
The charging cables available on the market by other
manufacturers frequently have different polarities. For
this reason, you should only use original Graupner
charging cables with order No. 3022.
Charging the transmitter battery using the plug-in
charger
The charging time with
the plug-in charger
provided in the set may
be up to 15 hours de-
pending on the existing
transmitter battery
charge.
Do not use
plug-in
chargers by other manufacturers or chargers
designed for different battery types. If the output voltage
is too high or the plug polarity is incorrect (see above), it
can cause signifi cant damage. We recommend labelling
the plug-in charger.
Consult the corresponding safety instructions on
pages 4 … 12.
The transmitter must be switched off while
charging. Never switch on the transmitter
when it is connected to the charger. If the
charging is interrupted even for a short time, the
charging voltage can rise enough to immediately
damage the transmitter from overvoltage. You should
therefore make sure that all plug-in connectors are
well-seated.
