Transmitter power supply
The
mc-32 HoTT transmitter is equipped with a
high-capacity, rechargeable LiIo 1s6p/6000 3.7 V
TX battery (No. 33000.1) as standard equipment.
(changes reserved)
However, the standard built-in battery is
not charged upon delivery of the transmit-
ter.
When the transmitter is used, its battery voltage should
be monitored by way of the indicators provided in the
LCD display. If the voltage level preset in the "Battery
warning" line of the »General basic settings« menu,
page 279, (default setting 3.60 V) is underrun, an
acoustic signal will be sounded and a warning mes-
sage will appear in the display.

Batt must
be re-
charged!!
No later than now, operation must be terminated so
the battery can be charged again.
Note:
Be sure the correct battery type is set in the
»General basic settings« menu, page
260! The standard setting for this is
"Lith.".
Charge the transmitter battery with the plug-in
charger.
The transmitter's rechargeable LiIo battery can be
charged by way of the charger socket located behind
a cover on the left, front side of the transmitter – as
viewed from the front – with the included plug-in
charger (No. 32032.4).
Depending on the state of discharge, the included
plug-in charger (4.2 V/500 mA) requires up to about
15 hours to fully recharge the transmitter battery.
Never use plug-in chargers from other manu-
facturers or chargers intended for other bat-
tery types. Charger output voltage which is
too high or possibly even different plug polarity, see
further below, can cause immense damage. We
recommend that this plug-in charger be appropriately
labelled.
Also observe the safety notices provided on pages
4 … 7.
The transmitter must be switched "OFF"
during the entire charging procedure. Never
switch on the transmitter when it is connected
to the charger. Even a brief interruption to charging
can cause charging voltage to rise to a level that will
immediately damage the transmitter with over-volt-
age. Also for this reason, be sure all connectors are
always plugged in securely and have good contact.
Opening the transmitter housing
Switch off the transmitter before opening it
(power switch to »OFF«). Push both housing
base latches in the opposite the direction of
the arrow marks, toward the inside, to their limits.
Now tilt the transmitter somewhat to the rear so the
housing base can fl ip open and can be unhooked.
Close the transmitter's housing base by fi rst hooking
it to the underside, fl ip the base closed then push
both latches toward the outside. When closing the
base, pay attention that no cables are pinched.
Notes:
•
Make no modifi cations of any kind
to the circuit boards as this will
void the guarantee as well as the
unit's offi cial permit.
• Be sure not to touch the circuit boards
with any metallic objects. Do not touch
contacts with your fi ngers.
• Before performing any tasks inside the
transmitter, disconnect the transmitter's
battery (see next page) to avoid potential
short circuit damage to the transmitter's
circuit boards.
