Please note!
Under power failure conditions this telephone will not operate. Please ensure that a separate
telephone not dependant on local power is available for emergency use. Do not place the base unit
close to other electrical equipment such as TV sets, computer screens, telecom equipment, fans etc.

Installation
Belt clip
A belt clip is permanently tted to the back of the handset allowing the handset to
be attached to a belt, waistband or similar.
Wall Mounting
The base unit can be wall mounted by tting the enclosed wall bracket to the
underside of the base unit. A click will be heard as it locks into place.
The wall bracket can be removed by pressing the lock tab located on the underside
of the base.
Battery
The telephone is supplied with environmentally friendly nickel metal hydride
(NiMH) batteries – 2 x AAA 1.2V. As with all batteries, performance may degrade
over time; should you notice that the standby time has reduced considerably or there
are signs of leakage, the batteries should be replaced.
Fully charged batteries will last for approx. 100 hours in standby or approx. 10 hours
call time. These operation times apply at normal room temperature.
Completely discharged batteries will take about 10 hours to fully recharge (24 hours
from new).
Please note that the battery charge indicator | in the handset display ashes
while the handset is charging and will stop when the battery is fully charged.
The base unit has an automatic charging mechanism that prevents the batteries
from being overcharged or damaged by prolonged charging.
Please note!
To ensure and maintain good charging of the handset battery/s we recommend that the base and
handset charge contacts are cleaned regularly, ie monthly, with a pencil eraser and/or a soft dry cloth.
The recharging system used in this model may result in the handset and the batteries warming up.
This is normal and will not harm the equipment.
When the telephone is installed for the rst time, the batteries must be charged for 24 hours before
use. Use DORO original batteries only. The guarantee does not cover any damage caused by incorrect
use of batteries. Please dispose of any batteries in a responsible and environmentally friendly manner.
Turning the Handset On/Off
Press and hold the ! button for a few seconds to turn the handset off or on.
When the handset is turned off, no calls can be made or received. The handset
is designed to be always turned on, i.e. it is not necessary to turn it off overnight.
However, we recommend turning the handset off if it is not to be used for a
prolonged period of time, e.g. during a holiday. If the batteries run low, the handset
will turn off.

Installation
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 reections that can reduce the range.
Specied 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.
