Calls using the PTT to speak:
To optimise the sound quality of the HTT-500, ensure that the terminal is
vertical with the antenna pointing upwards, between 2.5 and 10 cm from your
mouth, while you are pressing the PTT.
You can configure the groups so that they are on listen (scanned groups), so that you will
receive all the communications of the groups with this status. You can configure this by
programming or using the menu: Groups\Scanning lists.
You do not require any specific action to receive a group call to the selected group or to those
configured in scan. It will be received automatically and, on the screen, you can see the group
receiving the call and the identifier of the user that has made it.
7.2 Individual calls
Individual calls are private calls between 2 users. No other user can hear the conversation.
You can make these to numbers on the digital network (private calls) or to numbers on the
external telephone network (PSTN or PABX telephone calls).
In addition, they may be half-duplex (to speak you must press the PTT) or, if the network
allows it, duplex (the call is similar to a telephone call, and there is no need to press the PTT
to speak).
To make a private half-duplex call:
- Enter the number of the person you wish to call or select it from the contacts list.
- With the Mode soft-key select the type of call you wish to make. Next to the number you
have dialled, you will see the
symbol, which indicates that it is a private call.
