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.
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).
T echnical data Supply voltage range 10 V . . . 32 V DC Normal power supply voltage 13.75 V DC Power consumption at 13.75 V - “Standby” reception mode typ. 70mA - Reception mode typ. 500mA - T ransmission mode typ. 2,5 A T emperature range - 20° C .
CH 99 (bottom line) Indicates the storage channel CH indication flashes If the initiated storage operation (bottom line) is not completed by pressing the store key F (bottom line) Indication that the selected storage channel is not occupied V 1 1.7 (bottom line) Indication of supply voltage All indicating segment Supply voltage £ 10.
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.
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.
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.
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 .
o Mode 1 (standard mode) The last displayed active and preset frequencies appear in the LCD dis - play . 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.
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 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. In the scan function, the frequency appears in the top line of the display and the associated channel with the preset CS is shown in the bottom line.
l In the service mode the portable VHF station operates indepen - dent-ly of the settings on the control panel, on the frequency which was last set as the active frequency .
Service mode (equipment configurations) The service mode is meant to enable to set the equipment configuration. The following settings can be changed or set : SF 1 Setting the switch-on threshold of t.
