10-Meter Amateur Radio Base Station
Legal notes and general information
This amateur radio base station complies to the minimum requirements of the EU directives 2004/108/EG (EMC),
full fills the harmonized EU standards EN 301 783-2 (commercial available amateur radio products , EN 301 489-1
und-15 (EMC) und EN 60950-1:2006 (safety and LVD -directive 73/23/EWG) nad is marked with the CE logo.
Following conditions apply:
In all European countries this transceiver is subject to national amateur radio regulations. It may be used
only by persons, who have obtained a valid amateur radio licence.
Radio amateurs are only allowed to use this radio on assigned amateur radio frequencies within the 10 m
band, even if this radio should be able to switch other adjacent frequencies. National regulations may
exist for environmental RF protection and must be applied by the operator.
It is not allowed to use this radio for any other purpose except amateur radio.
If this radio shall be used in a configuration with other accessory items or amplifiers, the radio amateur is
responsible to keep the radiations within the legal limits of his licence class, especially he has to follow the rules
and standards of the above mentioned EU directive and technical standards, especially EN 301 783-2. It may be
necessary to add separate harmonics filters when combining to amplifiers or SWR meters or antenna switching
devices.
This radio is not declared to be used in cars during motion, because we cannot declare that there is no possible
influence on the electronic engine management. Please respect the automotive directive requirements, which
request that such devices are not allowed to be connected to the car network as long as the car engine is running.
These restrictions are only valid for passenger cars and trucks and do not apply to parking recreation vehicles,
boats or other environments with 12 V power supply.

1. POWER ON/OFF SWITCH
This switch turns the transceiver power on and off.
2. HEAD PHONE JACK
Connect head phone plug, Impedance > 32 Ohms, Mono
3. MICROPHONE INPUT
6 pin socket for Albrecht Standard Electret Hand Microphone
4. VOLUME CONTROL
Controls audio output level
5. SQUELCH CONTROL
Used to quiet the receiver during absence of receive signals
Sensitivity to incoming signals is fully adjustable
6. POWER CONTROL Fine adjusting of the Transmit Output Power, down to 3 W
FM/SSB or 0.5 Watt AM
7. CLARIFIER CONTROL
This control provides an adjustment for turning in stations which are slightly OFF
frequency, to optimise the AM and SSB reception and transmission.
8. RF GAIN & MIC GAIN CONTROL
Control the receiver sensitivity by RF GAIN CONTROL (outer knob) to reduce
interference. To decrease RF gain, turn the knob counter clockwise. For the
maximum receiver sensitivity, the RF GAIN control must be rotated clockwise.
