Note:
An antenna must always be connected. Always route the GSM cable away from
the microphone wires and the power supply wires to avoid interference on the speech
module.
IMPORTANT NOTE ABOUT SIM CARD
When using a pay monthly SIM card you must ask the service provider to put a spend limit
on the account (Vodafone call this service ‘spend checker’). This is to safeguard against
possible problems which could result in a large phone bill at the end of the month. All
providers offer this service. You will need to either ring them or e-mail them to set this up.
Automatic top ups should also have a monthly limit.
