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.

General operating notices
Transmitter power supply
mc-20
The
HoTT transmitter is equipped with
a high-capacity, rechargeable LiIo 1s6p/6000
3.7V TX battery (order no. 33000.1) as standard
equipment. (changes reserved) However, the
standard built-in battery is not charged upon
delivery of the transmitter.
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 260, (default setting 3.60 V) is underrun,
an acoustic signal will be sounded and a warning
message will appear in the display.

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 (order 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 manufacturers
or chargers intended for other battery 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
0:00.0
charger be appropriately labeled.
0:00.0
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
0
a brief interruption to charging can cause charging
voltage to rise to a level that will immediately damage
the transmitter with over-voltage. Also for this reason,
be sure all connectors are always plugged in securely
and have good contact.
