SECTION 3. OPERATION
USER SWITCH
The User Switch, or Power Switch, is located on the side of the reader. Pressing the User Switch
when the reader is off will turn the reader on. The reader will stay on for a predetermined
amount of time (the default is 60 seconds) or until the completion of a card read transaction.
Pressing the User Switch and holding for approximately one second when the reader is on will
extend the Activity Timer to its full period, avoiding having the reader turn off due to inactivity.
If the power is already on, pressing the User Switch and holding it for three seconds will turn the
reader off.
LED INDICATOR
Standalone Operation
When the reader is not attached to a USB cable it operates in Standalone mode. In this mode,
with the battery sufficiently charged and storage space available for transactions, cards can be
read.
USB Charging Only Operation
When the reader is attached to a charger via a USB cable (not attached to a USB host), it has the
same capabilities as in Standalone Operation plus the battery is charged.
USB Operation
When the reader is attached to a computer via a USB cable, it has the same capabilities as in
USB Charging Only Operation plus the ability to communicate with the hosting computer. Any
time the host puts the reader into suspend mode, the LED will turn off. Once the host takes the
reader out of suspend mode, the LED will indicate the battery state.
Battery Charging
Battery charging is initiated at the start of USB Charging Only Operation and at the start of USB
Operation. When battery charging is initiated, the voltage level of the battery is indicated via the
LED. If the battery is fully charged, the LED will be solid amber. If the battery is not fully
charged, the LED will blink amber very slowly.
Card Reading
Card reading may be initiated from any of the operational modes (Standalone, USB Charging
Only, or USB). Card reading is initiated by pressing the button while the reader is powered off
or while charging the battery.
When card reading is initiated, the level of the battery is tested and the LED will indicate the
state of the battery and of card reading operations:
1. If the battery has sufficient charge to perform this card read and several more, the LED
changes to green indicating the reader is ready for a card swipe and the Activity Timer is
set.
