1.2.3.1 Key lock mode switch
You will find the key lock mode switch. This switch will be explained in
more detail in the next section.
1.2.3.2 USB OTG
Continuing toward the back of the unit on the left side panel, you will find
the USB OTG. If you connect the unit to a personal computer by using
this USB OTG, you can transfer files that are stored in the Braille Sense
OnHand to your personal computer, and vice versa.
1.2.3.3 AC adapter jack
The last thing you will find on the left side panel of the unit is the AC
adapter jack. The AC adapter will plug in to this hole, and then plug in to
a standard AC electrical outlet, so that you can use the Braille Sense
OnHand with electricity, instead of using power from the battery.
1.2.4 Rear Panel
Next, let's take a look at the rear panel of the Braille Sense OnHand.
1.2.4.1 Reset button
On the far Right of the rear panel, you will find a small button in round
groove. This is the reset button. If your unit is not responding properly,
you can press this button with your finger, which will reboot the unit via a
hard reset. Pressing the reset button is a hardware reset. Do NOT
press the reset button for more than 5 seconds. You can also do a soft
reset by pressing F2-F3-1-2-3-4-5-6. This is a software reset, instead
of a hardware reset.
If you press down dots 1-2 and the reset button at the same time while
the power is on, the Braille Sense OnHand will turn on without speech.
