iWL251 GPRS model - Communication issues
The iWL251 GPRS terminal communicates using a roaming SIM card over
the following networks: O2, T-Mobile, Vodafone and Orange (Everything
Everywhere - EE).
Signal Gauge.
When on the READY screen, at the top of the terminal display
there is a signal gauge which shows the strength of the signal. The terminal
will automatically switch to an alternate network should it deem necessary.
Transactions on the
Move. Issues of this nature are minimised by the roaming
SIM. If you use the terminal whilst on the move it is possible that you can lose
connection with the GPRS network and the transaction will have
difficulties in completing as a result.
Enclosed Spaces.
If you use the terminal in enclosed spaces such as
basements, office complexes etc, you may experience difficulty in obtaining
any GPRS connection and processing transactions. Whilst the roaming SIM
helps such issues, the strength of the GPRS signal in these environments can be
limited. Try to ascertain these problem areas and do not use the terminal here.
Battery Information
The battery used to power the iWL251 terminal may not be fully charged
upon delivery. Please charge this battery for 3 hours prior to use. Whenever
the terminal is not in use it is advisable that the terminal is stored on the
charging cradle and connected to the mains supply.
Power Save.
If the terminal is not used for a certain period of time the
software will put the terminal into a Power Save mode to conserve battery
energy. The terminal can be re-activated by pressing any key.
Extra
Battery. If you find that the terminal is being used at conferences,
shows etc where there is little or no access to a power source it is worth
considering purchasing an extra battery. Please contact the Technical
Helpdesk / Client Services on the details below.
Should you require any further assistance please contact the Technical
Helpdesk / Client Services on 0345 600 8055 (UK) or 01 667 5152 (ROI).
