Operating Instructions

oFlashing 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 batteries for example, that the batteries require recharging. In prac-tice the display begins to flash in the transmit mode because this is when the power consumption is greatest. If the power supply again increases above 10.5 V, the flashing ceases.

Because the discharge curves of the batteries are very dependant on the type of battery, e.g. lead or nickel/cadmium accumulators, and the ambient temperature also influences the discharge curves, it is not possible to state precisely how long the portable VHF station continues to be fully functional after the LCD begins to flash.

When transmitting, the batteries can be completely discharged after a few transmission cycles but during reception functioning is still guaranteed in most cases for approximately 1 to 2 hours after the flashing be- gins.

oSetting the “channel start” scanning range (if funtion SF8 ac- tivated)

Call up function SF 13 using the MDE key. The following displays appear :

Top line

SF 13

Bottom line

CS channel number

Select the starting channel, using the kHz (steps of 1) or MHz (steps of

10)switch, at which the scan function is to begin. The starting channel is stored by pressing the STO key.
