2.3 Mains operation
Mains operation:
A plug-in power supply with controlled 6 V DC must be employed with min 1.5 A. For discharged
batteries the charging current will be approx. 290 mA. In this way, the accumulators are also
loaded simultaneously, also in the case of switched-off 7280.
During continuous operation on the net, it is recommended to remove the accumulators. For fast
loading to 100 % of the accumulators, an external loader (e.g. Ansmann 4 - 6) is recommended.
Prior to mains operation (disposable-) batteries must be removed from the
device, as they would be destroyed by the charging process and thus lead
to equipment damage !
Accumulator operation:
Use 4 x NiMH Mignon-Accumulators of min. 1600 mAh and 1.2 V correctly poled.
Accumulator charge time:
The accumulator charge time at accumulator-capacity of 2.7 Ah is approx. 9 - 10 h. At discharged
accumulators, the constant charging rate is approx. 290 mA. Charged accumulators are
recognized by the Minus-Delta-Peak-Procedure (overload protection).
Battery operation:
Use 4 x Mignon/AA batteries with 1.5 V
Never use a power supply plug when batteries are inserted !
Voltage supply:
If the admissible battery voltage falls below, the display starts to blink.
