If you don’t see the
3G
icon, try the following:
•
Have you made physical changes to your location? New walls or electronic devices
near the terminal may inadvertently reduce the wireless signal strength. Try walking
around your place of business to see if you are able to receive a signal.
•
Has something changed to the environment outside your place of business? A new
building may also reduce or block your signal strength. Try walking around your place
of business to see if you are able to receive a signal.
•
There may be an issue with the wireless phone network.
Signal Strength
The signal strength is represented by five to zero bars. Your terminal should always show at least
one in order to be able to complete transactions and ideally it should be a minimum of two bars.
10 0%
80%
60%
40%
20% / Low Zero / None
If the terminal is experiencing low or no signal strength, check the following:
Has the Bluetooth base become loose or unplugged? (TD iWL252 only)
Ensure the base is securely plugged into an electrical outlet.
Have any obstacles or electronic equipment been placed around the base or the terminal?
(TD iWL252 and TD iWL255)
If you have made physical changes to your location, such as adding a new wall or piece of
equipment, you may need to have the base moved to accommodate this change. Please contact
the TD Merchant Solutions Help Desk to assist with this if necessary.
What can interfere with Bluetooth connectivity?
The biggest issue is that the frequency range (2.4GHz) used by Bluetooth is shared by other
equipment and can be blocked by certain materials. There are steps that you can take that will
minimize Bluetooth connectivity issues. They are:
1.
Distance between the terminal and the base
Ensure that you keep your terminal and base in the same room if possible. Obstacles
such as walls or furniture may weaken or block the Bluetooth signal.
2.
Signal interference
Bluetooth uses the 2.4GHz frequency range which is shared by other devices such as:
•
Microwaves
•
Wi-Fi devices (routers, VoIP phones, wireless cameras)
•
Fluorescent office lighting
•
Some cordless phones and baby monitors
To avoid connectivity and data issues, avoid going near these devices when using the
TD iWL252 solution. Of course, you can’t always avoid sources of interference such
