Safety Precautions  
!
Safety Precautions  
Only use the power supply unit supplied, as indicated on the underside of  
the device.  
$
Fit only the recommended rechargeable batteries (page 73) of the same  
type! Use no other types of batteries or non-rechargeable batteries, as they  
could damage health and cause personal injury.  
Ensure correct polarity when fitting rechargeable batteries, and use the bat-  
tery type according to these instructions (you will see polarity symbols in the  
Œ
handset's battery compartments)  
.
The operation of medical appliances may be affected. Be aware of the techni-  
cal conditions within the particular environment (e.g. doctor's practice).  
The handset may cause an intrusive 'hum' in hearing aids.  
Do not install the base in bathrooms or shower rooms (page 69). The handset  
and base are not watertight.  
Do not use the phone in environments subject to explosion hazard (e.g. auto  
paint shops).  
Ensure that your Gigaset is accompanied by these instructions when you give  
it to others to use.  
ƒ
i
Dispose of the batteries and phone in accordance with environmental regula-  
tions.  
Not all of the functions described in these instructions are available in all  
countries.

Use only the rechargeable batteries recommended by Siemens on  
page 73! Never use conventional batteries (non-rechargeable) or other  
battery types as this may cause significant damage to health and prop-  
erty. For example, the jacket of the battery could be destroyed (hazard-  
ous). The phone could also malfunction or be damaged.

Preparing to use your phone  
Placing the handset into the base and charging the batteries  
When you place the handset into the base, the handset will register automatically to  
the base. Proceed step by step as follows:  
1. Place the handset in the base with the display up.  
2. Wait till the handset has registered automatically to the base (page 52): This opera-  
tion takes around one minute. While registration is in progress the screen displays  
Anmeldevorgang: and Basis 1 flashes. After registration, you will see a '1' in the  
top left of the display – this means that the handset has been assigned the first in-  
ternal number.  
3. Now leave the handset in the base for the batteries to charge – the batteries are sup-  
plied uncharged. Battery charging is indicated in the top right of the display by the  
battery icon = flashing:

Should automatic registration be interrupted, register the handset manually as  
described starting on page 53. You can get help from a table containing basic questions  
and answers (page 69).  
To register additional handsets , refer to page 53.  
i
For the initial charge we recommend a continuous, uninterrupted charg-  
ing period of five hours, whatever charge status is indicated. After a while  
the charge capacity of the batteries will decrease for technical reasons.  
W
The battery charging status is correctly displayed only after uninterrupted charging/  
discharging . You should therefore avoid removing the batteries unnecessarily and end-  
ing the charging process prematurely.  
N
Once initial charging is complete, you can replace your handset in the  
base after each call. Charging is controlled electronically. This ensures  
that the batteries are charged in a way that optimizes their life.  
i
N
The batteries heat up during charging. This is normal and not danger-  
ous.  
Note  
Your telephone is now ready for operation. With the Gigaset C 150, the answering  
machine with pre-recorded announcement is also activated. To correctly record the time  
of calls and messages (C 150) you should now set the date and time (page 14).

The handset activates automatically when placed in the base or charger.  
i
Activating/deactivating the keypad lock  
You can 'lock' the keys on your handset, e.g. when carrying the unit in your pocket or  
bag. This protects the keypad against inadvertent activation.  
Press the hash key and hold (confirmation tone).  
The Ø icon appears in the display  
To deactivate the keypad lock, press the hash key R again and hold (confirmation  
tone).

SMS (Text Messages)  
You can send and receive SMS text messages (Short Message Service) with your hand-  
set. You can write, edit, read, delete or forward text messages from any registered hand-  
set that has SMS functionality. When several handsets are in use at any one time, only  
one handset can access the SMS function.  
Please remember that when the SMS function is active the first ring is  
muted (page 60).  
i
General  
Text messages are exchanged between SMS centres that are operated by service provid-  
ers. The telephone number of the SMS centres through which you wish to send and  
receive text messages must be entered in your phone. Up to five SMS centres can be  
entered. SMS centres may be preconfigured at the factory. You can change the tele-  
phone numbers of the SMS centres.  
You can receive text messages from any of the SMS centres whose number you have  
entered. Of course you must be registered to receive text messages with those SMS cen-  
tres. Your text message is sent through the SMS centre that is entered as the active send  
service centre (page 29). Only one SMS centre can be the send centre at any one time.  
Your text message is sent through the SMS centre that is entered as SMS Centre No.  
1(active send service centre). However you can activate any other SMS centre as the  
active send service centre to send a current message (page 29). Note that the next text  
message you write will be sent automatically through SMS Centre No. 1 again.  
Sending text messages to email addresses  
If you wish to send text messages to email addresses you must make additional settings  
for the send centre on your phone (page 29). Ask your service provider if he supports  
the "SMS to email" service and what settings you must make.  
Storage capacity  
The number of text messages that can be stored in the base depends on the size of the  
messages. The memory is used for the incoming and draft message lists. When the  
memory is full, you are prompted to delete messages.

Text message sending and the draft message list  
If a call arrives while you are writing a message, then the message is automatically saved  
to the draft message list. You can take the call and finish writing or send the message  
later (page 33).  
Text messages that cannot be sent are assigned an error status (page 38) and are put in  
the incoming message list.  
Text messages are only stored automatically if sending is interrupted. If you wish to  
store a message then you must do so before it is sent.  
Your phone line is busy while your text message is being transmitted to the SMS send  
centre. The message Transferring SMS! is displayed on all handsets.  
Remember that some service providers will bill you for a cancelled call  
to the SMS centre. Deutsche Telekom's SMS Service will not charge for an  
interrupted call.

Writing text messages  
A single text message can be up to 160 characters long.  
If Russian or Greek is set as the display language on your handset, then you must change  
this setting before you write a text message (page 58). Select a display language that

Text messages to PABX's  
You can only receive a text message when the Calling Line Identification is for-  
warded to the extension of the PABX (CLIP).  
The CLIP of the number of the SMS centre is evaluated in the Gigaset (telephone).  
If your phone is connected to a PABX, you may have to prefix the number of the SMS  
centre with the access code (this depends on your PABX). If in doubt, you can test your  
PABX by sending a text message to your own number and putting the access code  
before the number of the SMS centre. If you do not receive the message, send another  
one, this time without the access code.  
When you send messages, your sender number may be sent without your extension  
number. The recipient cannot reply to you directly in this case.  
Text messages can only be sent and received through ISDN exchanges with the MSN  
number assigned to your base.

Any handset that is not registered on a base can be registered automatically.  
To register your handset for the first time, place it in the base with the display up. Reg-  
istration takes around one minute. While registration is in progress the screen displays
