4.1.5 Connecting a Headset
You can connect a headset to the audio socket on the side of the phone or in series with the
handset. The most convenient solution, and the lower cost alternative, is to use a headset on the
side of the phone. Headset output parameters include:
•
Rated Output: 12.5 mW
•
Impedance (Z
L
): 32 ohms
•
Microphone Type: condenser
•
Connector Type: 2.5 mm mono phone jack
Tip – Microphone
Ring – Speaker
Sleeve – Ground
Zultys supplies a headset with the phone, but you can buy good quality replacement headsets for
about $20.
Traditionally, headsets have been designed to plug in series with the handset. These also provide
good quality but typically cost $120.
With the ZIP4x4 you can choose either type of headset. Switching between the headset, handset,
and speaker is described in section 8.1.1 on page 71.
4.1.5.1 Using the Audio Connector
The connector on the side of the phone is a 2.5 mm socket. Connect the headset that came with
the phone or an alternative standard headset into this socket.
Do not buy a headset that has two connectors. These are normally used to connect to the sound
ports of a PC. Those connectors are 3.5 mm.
