Battery charge indicator

The symbol in the display indicates when it is time to recharge the
|
batteries. The indicator has three segments, which disappear as the battery
charge decreases. When the batteries are running low, a warning tone will
be heard. If the handset is not recharged at this time, the phone will cease to
function until it is recharged.

Range

The range of the telephone varies depending on different factors in the
surrounding environment. The radio waves transmitting the call may be
hindered by obstructions or signal reflections that can reduce the range.
Specified ranges require unobstructed transmission between the handset and the
base unit. In such ideal conditions the telephones range can be up to 300 metres.
In a densely populated area, house, apartment, etc. the range of the telephone
will be reduced. Try to get the best range by relocating the base unit. The ideal
location for the base unit is a high and unobstructed place.
Out of range warning
If during a call the handset is carried too far from the base unit a warning tone
will be heard. Unless the handset is moved closer to the base unit within a few
seconds the call will be lost. For information on how range warning is switched
on, see page 16.

Headset

When using an optional headset, there is no change in the way a call is received
or made. When a headset is connected, the microphone and earpiece of the
handset are automatically disconnected. This telephone supports the use of a
mute button on the headset cable.
Please note
Immediately reduce the earpiece volume on the handset when connecting an optional headset.
The performance of a non-original DORO headset cannot be guaranteed.
