Warning

Be sure to read this user guide and the safety precautions in detail before using your telephone. 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 connected.

Using your telephone may affect nearby medical equipment. Be aware of the technical 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 assistance, 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.

Batteries should not be disposed of in general household waste. Observe the local waste disposal regulations, details of which can be obtained from your local authority.

All electrical and electronic products should be disposed of separately from the municipal waste stream via designated collection facilities appointed by the government or the local authorities.

This crossed-out wheeled bin symbol on the product means the product is covered by the European Directive 2002/96/EC.

The correct disposal and separate collection of your old appliance will help prevent potential negative consequences for the environment and human health. It is a precondition for reuse and recycling of used electrical and electronic equipment.

For more detailed information about disposal of your old appliance, please contact your local council refuse centre or the original supplier of the product.

Please note

◆ Not all of the functions described in this user guide are available in all countries.
◆ The device cannot be used in the event of a power failure. It is also not possible to transmit emergency calls.

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:

◆Phone 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 available directly on the base station.
◆Use two telephone lines with only one telephone.
◆Make conference calls with two external parties (page 30).
◆View missed calls on your phone (page 19).
◆ECO DECT uses a power supply with low power consumption. Your handset reduces the transmission power depending on its distance from the base station (close-up range).

Note:

The transmission power of the base station is lowered to its minimum level when the handset is placed in the base station and only one handset is registered on the base station.

▶ Place the handset in the base station or charger with the handset's display facing outwards.

Charging the batteries for the first time

▶ To charge the batteries, leave the handset in the base station or charging cradle continuously for ten hours.

The alternately flashing battery icons □ on the upper right side of the display screen indicate that the batteries are being charged.

Note:

• If the handset has turned itself off because its batteries are empty, and you then place the handset into the base station, it will turn on automatically.
• Only place the handset into the base station or charging cradle specifically intended for it.
• During handset operation, the battery icon □ indicates the charge status of the batteries (page 3).
  – The batteries may feel warm when they are charging. This is not dangerous.

For questions and troubleshooting, seepage 34.

Setting the date and time

You should set the date and time, for example, to ensure the correct time of incoming calls is recorded.

Time and date can be set on the handset or on the base station.

To change the time and date, open the input field using:

Menu → □ → Settings → Date/Time → Set Date/Time

Enter the time and date using 10

digits, for example, 0 7 PQRS 1 a.o 5 JKL 1 a.o 5 JKL 0 1 a.o 1 a.o 0 for January 15, 2016 07:15.

To correct an incorrect entry, overwrite the character by typing the correct one.

OK Press the display key to save changes.

You can change the date and time format:

Menu → Settings → Date/Time → Set Format

▶ Choose between 12- and 24-hour time formats:

→ Time Format → 12 Hours / 24 Hours

▶ Choose between day/month and month/day date formats:

→ Date Format → DD.MM or MM.DD

Note:

Date and time settings apply to base station and all registered handsets.

Date and time format settings apply only to your own handset or to the base station. You must set date and time format at each device separately.

Selecting the line settings

For each handset and the base station, you can set how your telephone will use the two telephone lines:

Auto All incoming calls will ring. For outgoing calls, your phone will use whichever line is currently free.

Line 1 / Line 2

For incoming and outgoing calls, your phone will always use the selected line.

If you have selected Line 1 or Line 2, you can still answer or make a call on the free line by using the L1 or L2 keys.

Making calls

Making an external call

External calls are calls using the outside telephone network.

Enter the number and press the Talk key 📊 or Handsfree key 📋.

Or:

Briefly press the Talk key 📄 or Handsfree key 📋, and then enter the number.

To cancel the dialing operation, press the End Call key 🔒.

Depending on the line settings of the used handset/base station (see page 14), the telephone selects the line. You can use the line keys L1 or L2 instead of the R or key to select the line for this call.

You are shown the duration of the call while the call is in progress.

Note:

Dialing using the directory (page 18) or Calls list (page 19) saves time re-entering numbers.

Ending a call

Press the End Call key.

Answering a call

The handset indicates an incoming call in three ways: by ringing, by a display on the screen, and by the flashing Talk key .

The base station indicates an incoming call in three ways: by ringing, by a display on the screen, and by the flashing line key L1 or L2.

You can accept the call by:

▶ Pressing the Talk key ☐.
▶ Pressing the line key L1 or L2.
▶ Pressing the Handsfree key 📄.

Depending on the line settings of the used handset/base station (see page 14), the telephone reacts differently:

If you have selected Auto, you can use the Talk key 📄 or Handsfree key 📋 for calls on both lines.
If you have selected Line 1 or Line 2, you can only answer calls on the selected line with the Talk key 📄 or Handsfree key 📋. For calls on the other line, you must use the L1 key or L2 key 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.

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 displayed on the screen.

Note:

If two calls are ringing simultaneously on the two lines, your telephone display will switch from one line to the other every 3 seconds.

▶ Use the L1 key or L2 key to answer the call.

Caller ID

Caller ID (CID) is an optional subscription service provided by your telephone service provider. This feature supplies incoming caller identification information that will be displayed on your handset and the base station.

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 provider it is also possible that the phone number is shown twice on the display (on both lines), if the name is not available (for example in the phone book).

This behaviour changes depending on the network provider.

The following is displayed in place of the number:

◆External Call, if no number is transmitted, or the caller has not subscribed to Caller ID.
◆Withheld, if the caller has withheld Caller ID.

Handsfree operation

You can activate the speakerphone at any time to provide handsfree operation during a call.

Activating/deactivating handsfree

Activating while dialing

Enter the number and press the Handsfree key.

▶ You should inform your caller before you use the handsfree function so that the caller knows someone else may be listening.

During a call and when listening to the answering machine, turn handsfree on or off.

For how to adjust the volume, see page 31.
