About Your Phone

Contacting Emergency Services

This handset, like any wireless phone, communicates using radio signals. As with any wireless phone, you may not be able to establish a connection under all conditions; therefore, you should not rely solely on a wireless telephone for essential, emergency communication. The key lock feature disables the handset keypad and prevents the accidental dialing of numbers that may result in nuisance calls. It also prevents accidental calls to emergency services numbers like 911, 999, or 112.

To disable the key lock feature, press the key and then press the Yes softkey.

Currently, mobile IP phones do not support Enhanced 911 (E911) operation. If emergency services are required, it is necessary to keep the system administrator and location database up-to-date.

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 elsewhere 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.

Frequency Range

The handset is a radio transmitter and receiver. When it is on, it receives and sends out radio frequency (RF) energy. The handset operates on different frequency ranges depending on market and employs commonly used modulation techniques:

EU

b/g: 2400–2483.5 MHz (Ch 1–13) and

 

a: 5150–5350 MHz (Ch 36, 40, 44, 48, 52, 56, 60, 64), 5470–5710 MHz (Ch 100, 104,

 

108, 112, 116, 120, 124, 128, 132, 136, 140)

USA/CAN b/g: 2400–2483.5 MHz (Ch 1–11) and

a:5150–5350 MHz (Ch 36, 40, 44, 48, 52, 56, 60, 64), 5470–5710 MHz (Ch 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140), 5725–5875 (Ch 149, 153, 157, 161, 165)

Note: DFS channels should be avoided as Mobile devices are prevented from using these channels without a period of listening to ensure radar avoidance. This listening time causes delays in the ability to communicate with the WiFi infrastructure and therefore are not suitable for voice. Instead configure the PP to use UNII-1 channels.
