SAFETY INFORMATION 
1.  EXPOSURE TO RADIO FREQUENCY (RF) ENERGY 
Your phone contains a transmitter and a receiver. When it is ON, it receives and also 
sends out radio frequency (RF) signals. When you communicate w ith your phone, the 
system handling your call controls the power level at which your phone transmits. 
Your phone is d esigned to comply with local regulator y requirements in your cou ntry 
concerning exposure of human beings to RF energy. 
2. OPERATIONAL PRECAUTIONS 
To assure optimal phone perform ance and make sure human exposure to RF energy is 
within the guidelines set forth in t he relevant standards; always adhere to the follow ing 
procedures. 
3. EXTERNAL ANTENNA CARE 
Use only the supplied Avvio approved antenna. Unauthorized an tennas, modifications, 
or attachments could damage the phone. 
Do NOT hold the antenna when the phone is IN USE. Holding th e antenna affects call 
quality and ma y cause the phone to operate at a higher po wer level than needed. In 
addition, use of unautho rized a ntennas ma y result in non-com pliance w ith the local 
regulatory requirements in your country. 
4. PHONE OPERATION 
When placing or receiving a pho ne call, hold your phone as you would use a wireless 
telephone. 
To maintain compliance with RF energy exposure guidelines, ensure the phone antenna 
is at least 10 inches (25centimeters) from your body when transmitting. 
5. APPROVED ACCESSORIES 
Use of accessories not approved b y A vvio, including but not limited to batterie s and 
antennas, may cause your phone to exceed RF energy exposure guidelines. 
6.  RF ENERGY INTERFERENCE / COMPATIBILITIES 
8 
Page 10

Nearly every electronic device is susceptible to RF ene rgy interf erence from external 
sources if inadequately shielded, designed, or other wise configured for RF en ergy 
compatibility. In some circumstances your phone may cause interference. 
7. MEDICAL DEVICES 
1) Pacemakers 
Pacemaker ma nufacturers recommend that a minimum sep aration of 10 in ches 
(25centimeters) be maintained between the fixed wireless phone and a pacemaker. 
Persons with pacemakers should: 
Always keep the phone mor e th an 10 inches (2 5 centimeters) fr om your p acemaker 
when the phone is turned ON. Turn OFF the phone immediately if you have any reason 
to suspect that interference is taking place. 
2) Hearing Aids 
Some digital wireless phones may interfere with some hearing aids. In the event of such 
interference, you ma y want to consult your h earing aid manufacturer to discuss 
alternatives. 
3) Other Medical Devices 
If you use any other personal medical device, consult the manufacturer of your device to 
determine if it is adequatel y shielded from RF en ergy. Your physician may be abl e to 
assist you in obtaining this information. 
8. BATTERIES 
Batteries can cause prope rty damage and / or bodil y injur y such as burns if a  
conductive material such as jewelry, keys, or beaded chains touches exposed terminals. 
The conductive material ma y complete an el ectrical circuit (short circuit) and become 
quite hot.  
Exercise care in handling an y c harged b attery, particularly when placing it inside a 
pocket, purse or other cont ainer w ith met al object s. Use only o riginal batteries and
