Telephone base operation

Push to talk (PTT) intercom

You can directly broadcast messages to the speakerphone of any extension.
The extension you called can respond by pressing the INT key to begin a two-
way communication. Any registered cordless handset/deskset can make PTT
calls with each other or with the telephone base. Up to five pairs of PTT calls
can be maintained at a time.

PTT to a single device

1. When the system is idle, press and hold the one-touch
EXT 1-0 key of the destination party. When the connection
is made, both the caller and the destination party hear
two beeps. The telephone base screen shows PTT to:
X:Handset X Release PTT key to stop (X represents
the extension number [1-0], Handset X represents the
handset name) or PTT to: X:Deskset X Release PTT
key to stop (X represents the extension number [1-0],
Deskset X represents the deskset name).
2. Speak into the base speakerphone while continuing to hold down the one-
touch EXT 1-0 key. Your voice is broadcast to the desired extension.
3. Release the one-touch EXT 1-0 key after speaking. There is a three-second
PTT wait state with -MUTE slowly flashing on the screen and
the MUTE indicator flashing. During the PTT wait state, if
necessary, you can press and hold the previous one-touch EXT
1-0 key or the INT/PTT ALL key to continue speaking into the
base speakerphone.
4. The destination party can now respond (see Answer a PTT call in the
SynJ SB67108 handset manual or SynJ SB67148 deskset manual).

PTT to all devices

1. When the telephone base is idle, press and hold the INT/PTT ALL key to
automatically activate the speakerphones of all the extensions. Both the
caller and the destination parties hear two beeps.
2. Speak into the base speakerphone. Your voice is broadcast to all
extensions. Release the INT/PTT ALL key after speaking. There is a three-
second PTT wait state with -MUTE slowly flashing on the screen and the
MUTE indicator flashing. During the PTT wait state, if necessary, you can
press and hold the INT/PTT ALL key to continue speaking into the
base speakerphone.
3. Any extension can reply. The first extension to reply will either convert the call
into a normal intercom call with the caller or start a new PTT call. See Answer a
PTT call in the SynJ SB67108 handset manual or SynJ SB67148 deskset manual.
