DR301 is a battery operated unit, and displays the battery capacity on
the screen.
Low Battery
When the battery icon blinks you need to replace the batteries immediately.
When the batteries are exhausted the display will show “Low Battery” and
the unit will be turned off automatically within a few minutes.
Rechargeable batteries may be used with DR301. An external charger is
required. For optimum use, Nickel Metal Hydride (Ni-MH) types are recom-
mended.
DR301 works with an optional mains adaptor. The adaptor must provide a
regulated power supply of 5V, 300mAh. The use of unregulated supplies or
different voltages may cause permanent damage to the unit. A suitable
mains adaptor can be purchased from Perstel Limited.
For connection, plug the adaptor into the socket on the side of the unit. The
internal batteries are disconnected when the power adaptor is plugged in.
