About Feature Access Codes

Use of some features requires dialing access codes. The codes are flexible and may be
different than those in this guide. Ask your Administrator for a list of codes you should
use.

For Users on Resilient 3300 ICP Systems

If during a call, you hear two beeps that are repeated every 20 seconds it means that
your phone is switching to a secondary 3300 ICP system. The call continues but some of
the keys and features on your phone function differently. The keys and features begin
working normally again after you hang up. If your phone switches to the secondary
system while your speaker or handset is muted (that is, while the MUTE key light is
on), the call remains muted until you hang up. Normal operation resumes when your
phone switches back to the primary system. If your phone is idle and switched to the
secondary system, you'll see a flashing rectangle on the display. The rectangle remains
until the switch to the primary system is complete.

5224 IP Phone and Line Interface Module

The Line Interface Module is an optional device that adds an analog phone line (POTS)
capability to your 5224 IP Phone (only). If Emergency Call Routing is not programmed
on your 3300 ICP, you must use the Line Interface Module to dial emergency calls. For
more information on emergency number dialing, refer to Emergency Calls.
If you have a Line Interface Module connected to your 5224 IP Phone, all programming
of the Line Interface Module, except the Analog Key, is done by the Installer when your
phone is installed. For more information, refer to "Using the Line Interface Module" in this
guide.
Note: The 5212 IP Phone does not support the Line Interface Module.

Tips for Your Comfort and Safety

Don't cradle the handset!

Prolonged use of the handset can lead to neck, shoulder, or back discomfort, especially
if you cradle the handset between your ear and shoulder. If you use your phone a lot,
you may find it more comfortable to use a headset. See the section on headset usage in
this guide for more information.

Protect your hearing

Your phone has a control for adjusting the volume of the handset receiver or headset.
Because continuous exposure to loud sounds can contribute to hearing loss, keep the
volume at a moderate level.
