USING THE HANDHELD DEVICE
Powering The Handheld Device
The iFob Transfer Unit application firmware that runs inside the Traka Handheld Device automatically puts the unit into
a low power standby mode if there is no user interaction for a preset period of time. The factory default setting for this
timeout is 20 seconds.
In the standby state the unit is switched into power save mode turning off the reader and LCD and putting the on-
board microcontroller to sleep. To wake the unit, press Function Button 1, the left hand button looking at the front of
the unit. The unit will wake from standby and display the following message on the LCD as it boots up:
If during the boot-up sequence the battery level is found to be below the low battery threshold, then the unit will emit
a warning tone and the display will show the following message:
If during the boot-up sequence the biometrics reader cannot be initialised then the display will show the following
message:
NOTE:
The unit will also boot up from sleep mode when a live USB cable is inserted or removed. After the
timeout period the device will go back to sleep however the charging status LED will remain lit.
Charging the Handheld Device
The Traka Handheld Device can be charged through a standard USB port. It may also be charged using in-car USB
accessory leads or mains-to-USB power supply devices (supplied).
NOTE:
The unit cannot be charged from passive USB hubs (i.e. hubs that take their power directly from the
bus). Connect either directly to a PC or to hub that uses an external power supply.
The Traka Handheld Device has a standby battery lifetime of 280 hours. The battery life in use will depend on how
frequently the unit is operated.
The LED inside Function Button 1 is used to show the battery status. The table below summarises the different LED
statuses possible:
