Third Party Equipment
The use of third party equipment, cables or accessories, not made or authorized by ZTE,
may invalidate the warranty of the handset and also adversely affect the handset’s
operation. For example, use only the ZTE charger supplied with the handset.
Efficient Use
For optimum performance with minimum power consumption, do
NOT
cover the antenna
area (It’s on the bottom of your phone) with your hand. Covering the antenna area affects
the call quality, may cause the handset to operate at higher power levels than needed, and
may shorten talk and standby times.
Radio Frequency (RF) Energy
Your handset is a low-power radio transmitter and receiver. When it is turned on, it
intermittently receives and transmits Radio Frequency (RF) energy in radio waves to
handle and control the power level at which the handset transmits.
Emergency Services
Note:
Emergency numbers vary by country.
To make an emergency call in any country:
1. Ensure your handset is ON and in service.
2. Press the End key as many times as needed to clear the display and ready the device
for calls.
