8 Safety Information
NOTE1: BEFORE connecting the
Telit EZ10 Terminal
to a Power Supply source, a suitable
Antenna shall be connected and properly installed.
NOTE2: BEFORE connecting the Power Supply equipment to the mains socket, verify at
least that the Input Voltage (V) and Frequency (Hz) range indicated on the equipment
includes the Voltage and Frequency of the present mains (grid).
NOTE3:
Always verify the
Type Labels
on the under side of the
Telit EZ10 Terminals
in order to
identify the model and especially the
version of the Interfaces at the RJ11 connector
. This
connector can bear AUDIO lines or GPIO lines. It can be identified by the writing
AUDIO
in older
production lots or by the writing
AUX=AUDIO or AUX=GPIO
in newer production lots.
The
Telit EZ10-PCS
with PYG Option
has General Purpose Inputs/Outputs instead of the
Audio/Remote Power ON/OFF lines on the RJ11 connector.
Before connecting any equipment and before taking the EZ10 into operation, make sure
which configuration applies according to the type label of the EZ10 and that this
configuration is compatible with the equipment and the Application (as DTE) which uses the
EZ10.
NOTE4:
The product has to be handled with care, avoiding any contact with the connector pins,
because electrostatic discharges may damage the product itself. The same cautions have to be
taken for the SIM, checking carefully the instructions for its use.
Do not insert or remove the SIM
when the product is in power saving mode.
8.1 Precautions When Using Batteries
The
Telit EZ10 wireless modem
as such does not contain batteries, but in some applications
external batteries might be used, for which the following precautions are valid:
•
Never use any charger or battery that is damaged in any way.
•
Use the battery only for its intended purpose.
•
If you use the
Telit EZ10 wireless modem
near the network’s base station, it uses less
power; talk and standby times are greatly affected by the signal strength on the cellular
network and the parameters set by the network operator.
•
Battery charging time depends on the remaining battery charge and the type of battery and
charger used. The battery can be charged and discharged hundreds of times, but it will
gradually wear out. When the operation time (talk time and standby time) is noticeably
shorter than normal, it is time to buy a new battery.
•
If left unused, a fully charged battery will discharge itself over time.
•
Use only approved chargers. When a charger is not in use, disconnect it from the power
source. Do not leave the battery connected to a charger for more than a week, since
overcharging may shorten its life..
•
Extreme temperatures will affect the charging capacity of your battery: it may require
cooling or warming first.
