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.[...]

o Setting the “channel end” scanning range (if funtion SF8 ac - tivated) Call up function SF 14 using the MDE key . 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. [...]

o Inhibiting the frequency setting (channel selection only) Call up function SF 10 using the MDE key . The following displays appe - ar : T op line SF 10 Bottom line 0 or 1 Select the required function using the kHz key and store the function by pressing the STO key . 0 = Frequency setting not possible. The VHF station can only work on the frequenc[...]

The preset frequency (bottom line) is set using the MHz and kHz fre - quency selector switches. When the exchange key is pressed, a change from the active to the pre - set frequency occurs. A further operation of the key cancels the frequen - cy[...]

o Setting the IC level Call up the SF4 function using the MDE key . The following displays ap - pear : T op line SF 4 Bottom line 00 to 63 The IC level can be changed upwards or downwards using the kHz switch. The set value is stored by pressing the STO key . o Calibrating the temperature sensor Not activated in the portable VHF station. SF5 is not[...]

o Scan function If the scan function is activated in the equipment configuration, pressing the STO key changes from the channel selection mode to the scan function.
