General information Carrying case and transceiver together form a portable VHF station. The easily-portable VHF station can be used, for example, for mobile and fi - xed operations on airfields or landing strips. It an also be used in hot air balloons, for ferrying aircraft or or recovery of gliders. The carrying case contains the battery , speaker[...]

Servicing and operation of lead-acid batteries Lead-acid batteries are to be charged immediately after use. Disch - arged lead-acid batteries are to be charged for approximately 16 hours at 1/10 of the rated capacity. A few basic rules need to be observed in the handling of lead-acid batte - ries, to maintain their service life over several years. [...]

Operating instructions Connect the antenna and the mike to the corresponding connection jacks. o Switching on the unit Switch on the portable VHF station using the ON/OFF switch (rotate vo - lume control clockwise). The battery charger shall be operated at a distanced of at least 50 cm (maximum cable lengt) from the portable VHF-Transceiver, to avo[...]

o Channel priority ON/OFF switch (option upwarts serial no.: 46) Call up function SF 18 using the MDE key . The following displays appe - ars : T op line SF 18 Bottom line CS channel number Using the kHz (steps of 1) or MHz (steps of 10) switch, select the de - sired channel. Store the channel by pressing the STO key . Several channels can be selec[...]

o T ransmit/receive mode Set the frequency in the preset display and press the exchange key . Ro - tate the VOL control to the centre position. Operate the transmit button and call the other station. Hold the micro - phone close to the lips for optimum speech transmission. NOTES l The triangle in the top line of the display indicates transmit mode.[...]

The following displays appe - ar : T op line SF 14 Bottom line CS channel number Using the kHz (steps of 1) or MHz (steps of 10) switch, select the end channel at which the scan function is to stop. Store the end channel by pressi[...]

o Flashing of the LCD If the power supply for the portable VHF station drops below 10.5 V , the display begins to flash. This flashing indicates, when operating on batte - ries for example, that the batteries require recharging. In prac-tice the display begins to flash in the transmit mode because this is when the po - wer consumption is greatest. [...]
