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 talk on the phone a lot, you may find it more comfortable to use a headset. See Headset Operation for more information.
Protect your hearing
Your 5140 IP Appliance 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.
Adjusting the viewing angle
The stand built into your 5140 IP Appliance tilts to give you a better view of the keys.
To adjust the viewing angle:
1.Depress the button on the stand at the back of the set.
2.Slide the stand in or out to achieve the desired angle.
3.Release the button.
FOR USERS ON RESILIENT 3300 ICP SYSTEMS
If during a call, you hear two beeps repeated every 20 seconds it means that your phone is switching to a secondary 3300 ICP system. The call continues but the keys and features on your phone stop working. The keys and most features begin working again after 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.
