Remark: The Commander Zweitbesprechung is also available without call buttons.
General Remarks
The Commander Zweitbesprechung R is a hand set designed for the use as a secondary device in
addition to a BOS radio on the same radio circuit. The scope of delivery includes the handset with
integrated Call1 and Call2 functions and the corresponding rest with a loudspeaker and volume control.
An AF amplifier is also integrated into the rest.
A 10-pin terminal block inside the rest connects operating voltage, squelch, PTT output and AF in/
output with the radio. Additionally, an external loudspeaker can be connected.
As the AF output is only open during transmission, several Commander Zweitbesprechung can be
connected in parallel.

Status Display (yellow LED)
The status display always lights, if the radio is operating.
Squelch Display (red LED)
The squelch display lights up, while a carrier is detected by the raio receiver.
Transmission Display (green LED)
The transmission display lights up during transmitter keying (PTT). The transmitter is keyed by pressing
the PTT button inside the handset or one of the two Call buttons.
Conversation Handling
By pressing the PTT button at the inner side of the handset, the transmitter is activated and ready to
speak. You can hear the radio transmissions in the earphone and via the loudspeaker. The loudspeaker
volume (internal and external) can be adjusted using the potentiometer at the side of the rest.
While PTT is keyed or while the handset is taken the loudspeaker can be muted (jumpers 6 and 9).
Volume
Using the potentiometer on the left side of the rest, the volume of the internal and external loudspeakers
can be adjusted. Using jumper 5 a minimum volume can be defined. The volume cannot be lower
than this value even if the potentiometer is turned to very low values.
Tone Call Encoder
The Commander Zweitbesprechung R has an internal tone call encoder for Call1 and Call2. These
calls are transmitted by pressing the respective buttons on the upper side of the handset. The tone
call is sent as long as the button is pressed.
Call 1 = 1750 Hz
Call 2 = 2135 Hz

Adjusting the Microphone Level
The microphone level of the handset is adjusted correctly ex factory. If you still wish to change it, the
output level can be adjusted using the potentiometer near the microphone capsule at the outer side
of the handset.
The rest includes an AF amplifier that can be configured for different operation modes. It supplies the
int. and ext. loudspeaker with a maximum of 3 watt each. The used signal is derived from the earphone
AFand hence is independent from volume settings of the radio. If necessary, the basic sensitivity can
be adjusted with the poti inside the rest. Ex factory, a level of 500 mV is set.
The integrated AF amplifier can be muted for the internal and external loudspeaker. Muting is always
active when PTT is keyed. Furthermore, muting is active while the handpiece is taken if jumper JP1
is closed (factory default).

Function Squelch or Hook
To pins 8 and 9 of ST1 a squelch signal of the radio can be applied in order to display a carrier and
to activate/deactivate the loudspeaker (fatory default: JP2/JP3 closed at the bottom)
Alternatively, these pins can be used as an output of the hook status via a semiconductor relay (JP2/
JP3 closed at the top)
Connection to FuG8/9
The connection is accomplished via a cable with BOS plug.

General Safety Information
Please read the operating instructions carefully before installation and setup.
The relevant regulations must be complied to when working with 230V line voltage, two-wire-
lines, four-wire-lines and ISDN-lines. It is also very important to comply to the regulations
and safety instructions of working with radio installations.
Please comply to the following safety rules:
- All components may only be mounted and maintained when power is off.
- The modules may only be activated if they are built in a housing and are scoop-proof.
- Devices which are operated with external voltage - especially mains voltage - may only
be opened when they have been disconnected from the voltage source or mains.
- All connecting cables of the electronic devices must be checked for damage regularly
and must be exchanged if damaged.
- Absolutely comply to the regular inspections required by law according to VDE 0701
and 0702 for line-operated devices.
- Tools must not be used near or directly at concealed or visible power lines and conductor
paths and also not at and in devices using external voltage – especially mains voltage -
as long as the power supply voltage has not been turned off and all capacitors have been
discharged. Electrolytic capacitors can be still charged for a long time after turning off.
- When using components, modules, devices or circuits and equipment the threshold
values of voltage, current and power consumption specified in the technical data must
absolutely be complied to. Exceeding these threshold values (even if only briefly) can
lead to significant damage.
- The devices, components or circuits described in this manual are only adapted for the
specified usage. If you are not sure about the purpose of the product, please ask your
specialized dealer.
- The installation and setup have to be carried out by professional personnel.
