Remark: The Commander Zweitbesprechung is available with call buttons as well.
General Remarks
The Commander Zweitbesprechung O 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 together
with the corresponding rest. The AF amplifier is integrated in 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.

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
volumes (internal and external) can be adjusted using the potentiometers 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).
Using jumper 5 a minimum volume can be defined. The volume cannot be lower as this value even if
the potentiometer is turned to very low values.
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 (poti R8) is set.
The integrated AF amplifier can be muted for the internal and the external loudspeaker. Muting is
active on PTT if jumper JP9 is set (factory setting). While the handset is taken, muting is active if
jumper JP1 is set (factory setting).

Function Squelch or Hook
To pins 8 and 9 of ST1 a squelch signal of the radio can be applied (factory setting, JP2/JP3 closed
at the bottom). The squelch function is not used at Commander Zweitbesprechung O.
Alternatively these pins can be used to indicate the status of the hook via an opto-coupler (JP2/JP3
closed at the top).

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.
