Safety and installation notes – please observe!
Caution
The mains voltage must match the rated input
voltage of the unit (230 VAC).
Connecting cable — Lay the cable so that no-
one can trip over it.
—Lay the cable with a
downward loop so that any condensing on it
can drip on the floor instead of running into it.
Selecting the installation location
Excessive temperatures will reduce the operating
lifetime of the unit. Do not install the unit directly
above or in the vicinity of radiators or heating
systems where it would be subjected to thermal
radiation or oil vapours.
Cleaning
Only use a dry soft cloth to clean the cabinet.
Do not use solvent.
Moisture
Water dripping or splashing onto the unit will
damage it. If there is condensation on the unit,
wait until this has evaporated before switching
the unit on.
Caution – danger!
In accordance with EN 50 083-1, the antenna
system must comply with the safety requirements
with respect to grounding, potential
equalisation, etc.
Service work
Service work may be carried out only by qualified
personnel. Always disconnect the supply voltage
before starting any such work.
Important
Leave a minimum space of 15 cm. around to the
product to guarantee a maximum of ventilation.

Attenuator settings
The amplifier consists of 3 UHF inputs. They are splitted into 10 clusters.
A cluster is a group of channels consisting of max. 7 channels.
Choose the combination by yourself with setting "Start" and "Stop"
channels.

Note:
Setting the "Start channel" (example ch 33)
also sets the "Stop channel" autom. to ch 33.
Switching off a cluster
- Select "Start" channel and set to OFF.
The "Stop" channel"is set autom. to OFF.
Overlapping cluster
-*The digit displays overlapping.
5. Attenuator
- Set the attenuator 0-30 dB for each cluster.
Setting cluster inputs
The 3 UHF inputs of the amplifier are splitted
into 10 clusters.
The input can only be configured for
cluster 8, 9, and 10.
Select the "Parameter-Submenu" and
configure the inputs.
Note:
Cluster 1 and 2 are assigned to UHF 1.
Cluster3, 4, 5, 6 and 7 are assigned to UHF 2
Cluster 8, 9 and 10 are assigned to UHF 2 or 3.
Each cluster can be set to OFF. For example:
only one cluster is needed for UHF 2,
switch OFF the other clusters.

Copy function with OK 41A (Accessory)
The data import function allows to store settings from the OK 41A handset or from another VS 21.
The OK 41A consists of 10 "Memories". Select one of the OK 41A memory ("Position1...10").
Select "Data import" to store the datas from master and restore to the -Unit to be set- with "Data
Store"
General attenuator UHF
Select in the "Main Menu" - "General Att. UHF" and press  again to enter the "Parameter-
Menu". All input levels can be set. The default setting for this attenuation is 11 dB.
Automatic level adjustment
1. First select the START and STOP channels
for each cluster.
2. Set the clusters to OFF which are not in use.
3. Start "AGC".
4. The amplifier starts levelling automatically
the clusters.
This procedure will take about 1 to 2 minutes,
depending on the number of channels and
clusters to be equalized.
5. The amplifier displays the results in the
parameter sub-menu:
CL. 1 XXXX I XXX II
II
IXI
cluster 1
parked cluster
cluster 5
signal weak
cluster 9
signal strong
Note:
The automatic level adjustment set the output
level of the clusters at 100 dBµV (for an input
level between 50 to 80 dBµV).
The general attenuator is fixed to 11 dB after
the automatic level adjustment. It can be
adjusted from 0 to +20 dB to get a level
between 90 to 110 dBµV (see "General Att.
UHF ).
The difference between analog and digital
signals is very small. You can correct this after
automatic levelling has finished.
