OPERATOR'S MANUAL FOR THE SYSTEM
3.2 BATTERY OPERATION
The mobileMOSFET is intended to operate on battery power. The battery level for the
mobileMOSFET Reader Module is indicated on the Equipment Setup and Dose
Measurement screens, as well as windows that will pop-up advising you if your
battery level is getting low. There are two methods to recharge the batteries, Fast
Charge and Trickle Charge. The charging status is visible by the LEDs on the side of
the Reader. A green LED indicates that the unit is in Trickle Charge, while a red LED
indicates the Reader is in a Fast Charge.
To Fast Charge the mobileMOSFET Reader Module, ensure the unit is turned OFF
prior to connecting the unit to a power source. A Fast Charge will completely charge a
mobileMOSFET with a drained battery in approximately three hours. Once the
batteries are charged, the red LED will go out and the green LED will come on,
indicating Trickle Charge.
Trickle Charge supplies the battery with power at a continuous low rate thereby
keeping it charged. Trickle Charge allows the user to continue treatment sessions
when the Reader's battery is running low. Instead of having to be concerned with the
battery losing power, the user can just continue on with the session. To use Trickle
Charge, the mobileMOSFET must be ON and the power supply connected to the
Reader.
Prior to first use, place the Reader on Fast Charge (mobileMOSFET turned OFF
and power connected) until the red (Fast Charge) LED goes OFF and the green
(Trickle Charge) LED comes on. This will take a maximum of three hours.

3.3 CONFIGURE BIAS SENSITIVITY
The Bias located inside the Reader provides regulated voltage to the MOSFET
dosimeters. This ensures reproducibility and linearity over the lifetime of the
MOSFET. The mobileMOSFET Reader provides a choice of two Bias sensitivities in
order to cover a wide range of doses with optimum reproducibility. The system allows
you to choose between two options: Standard (STD) for routine use, or High (HI)
Sensitivity for low doses.

ATTENTION
BEFORE USING THE mobileMOSFET, IT IS RECOMMENDED THAT YOU CHOOSE ONE
SENSITIVITY SETTING AND LEAVE IT THERE FOR THE DURATION OF THE LIFE OF THE
DOSIMETERS TO BE USED.
