Before Using Your Handset

Hearing Aid Compatibility
Radio frequency can interfere with some hearing aids. Your handset has a hearing aid compatibility
mode that adjusts the frequency response for users who have hearing aids equipped with telecoil
inductive pickups. Acoustic pickup hearing aids will not respond to this adjustment.
To view the current status of the Hearing Aid Compatibility feature and to enable or disable this feature,
navigate to Settings > Basic Settings > Hearing Aid Compatibility.
Registering Your Handset
Generally, your system administrator will deploy your handset with multiple other handsets. In this case,
your system administrator will configure the handset parameters beforehand so that the handset will
register with the system and be ready to use when you turn it on.
The system administrator must register the handset or it will not work. If your handset does not work
when you turn it on, contact your system administrator.
Initializing the Handset
When you turn on the handset, it will cycle through an initializing sequence. Allow this sequence to
continue until you see the Home screen and the registration icon ( ) in the Status Bar. The
initializing sequence is as follows:
1 A facility logo displays for about 15 seconds.
2 The screen message displays: Starting application, press Cancel to interrupt. If you press the
Cancel soft key, you will interrupt the startup cycle. Do not press the Cancel soft key unless
directed by your system administrator.
3 The Home screen displays with the registration successful icon in the Status Bar ( ).
If registration fails, you will see an icon showing registration failed ( ). For a summary of these
icons, see Table 1: Status Bar Icons. If registration fails, turn the handset off and then back on.
Contact your system administrator if registration continues to fail after several attempts.
