service must be supported by the service provider. If

your service provider does not support this service,

see below the instructions on explicit call transfer.

i You can put all parties on hold by entering

FLASH and key “2”.

Explicit Call Transfer

With the presence of two established calls, pressing

FLASH “4” keys connects the two distant parties

and disconnets the GSM Terminal from both

calls. However, some service providers implement

a proprietary solution for explicit call transfer using

special service codes. You can use special explicit call

transfer service codes between two established calls

by following these steps:

• Put the calls in conference call by pressing

FLASH and the key “3”.

• Put the calls on hold by pressing FLASH and

the key “2”. You should get a dial tone.

• Dial the explicit call transfer code to complete

the explicit call transfer operation.

GSM RELATED SUPPLEMENTARY SERVICES

The GSM Terminal provides transparent access to all

standard GSM Supplementary services. Since some

of the services need an extra subscription, consult

your service provider for the availability of these

services.

Table 2 on page 12 lists the services supported by the

GSM Terminal and instructions on how to activate

and deactivate them, as well as on how to query the

status of each service.

i Successfully completed actions are indicated

by a single acceptance tone while incomplete

or unsuccessful supplementary Service requests

are indicated by three monotonically increasing

failure tones.

i Status queries will provide a single tone

indicating an activated service and two

monotonically decreasing tones (“negative

acknowledgement tone”) indicting a deactivated

service.
