Safety precautions
Warning
Be sure to read this user guide and the safety precautions in detail before using your tele-
phone. Explain their content and the potential hazards associated with using the telephone
to your children.
Use only the power adapter supplied, as indicated on the underside of the base.
Use only rechargeable batteries that correspond to the specification provided
(see page 35), as this could otherwise result in significant health risks and personal
injury. Do not charge the handset in the charger or base while the headset is con-
nected.
Using your telephone may affect nearby medical equipment. Be aware of the tech-
nical conditions in your particular environment e.g., doctor's surgery.
Do not hold the rear of the handset to your ear when it is ringing or when handsfree
mode is activated. This may cause serious and permanent damage to your hearing.
Your Gigaset is compatible with the majority of digital hearing aids on the market.
However, perfect function with all hearing aids cannot be guaranteed.
The handset may cause interference in analogue hearing aids. If you require assis-
tance, please contact the hearing aid supplier.
Do not install the base or charger in bathrooms or shower rooms. The base and
charger are not splashproof.
Do not use your phone in environments with a potential explosion hazard (e.g., paint
shops).
If you give your phone to a third party, make sure you also give them the user guide.
Remove faulty bases from use or have them repaired by our Service, as these could
interfere with other wireless services.

Version 4, 16.09.2005
Gigaset C285 – more than
just a telephone
Your phone not only lets you store up to 250
phone numbers (page 18), it can do a whole
lot more:
uPhone directly using the base station:
Your base station has the same keys as
your handset. So nearly all functions you
usually use on the handset are also avai-
lable directly on the base station.
uUse two telephone lines with only one
telephone.
uMake conference calls with two external
parties (page 30).
uView missed calls on your phone
(page 19).
uECO DECT uses a power supply with low
power consumption. Your handset
reduces the transmission power depend-
ing on its distance from the base station
(close-up range).

Version 4, 16.09.2005
You can accept the call by:
¤Pressing the Talk key c.
¤Pressing the line key Cor h.
¤Pressing the Handsfree key d.
Depending on the line settings of the used
handset/base station (see page 14), the tele-
phone reacts differently:
uIf you have selected Auto, you can use
the Talk key c or Handsfree key d
for calls on both lines.
uIf you have selected Line 1 or Line 2, you
can only answer calls on the selected line
with the Talk key c or Handsfree key
d. For calls on the other line, you must
use the Ckey or hkey to answer the
call.
If the handset is in the base station or
charger and the Auto Answer function is
activated (page 31), the call will be answered
automatically when you lift the handset
from the base station or charger. Lifting the
handset from the base station or charger in
this case has the same effect as pressing the
Talk key c.
You can press the §Quiet§ display key to mute
the ring tone of your handset without
answering the call. The other registered
handsets and the base station keep ringing.
You can answer the call as long the call is dis-
played on the screen.
Caller ID
Caller ID (CID) is an optional subscription ser-
vice provided by your telephone service pro-
vider. This feature supplies incoming caller
identification information that will be dis-
played on your handset and the base sta-
tion.
Call display with Caller ID/Name
If the number of the caller is stored with a
name in the directory, on the display you will
see both number and name.
Depending on the information that Gigaset
C285 receives from the network of your pro-
vider it is also possible that the phone num-
ber is shown twice on the display (on both
lines), if the name is not available (for exam-
ple in the phone book).
This behaviour changes depending on the
network provider.
The following is displayed in place of the
number:
uExternal Call, if no number is transmitted,
or the caller has not subscribed to Caller
ID.
uWithheld, if the caller has withheld Caller
ID.
