11.1.5 PROTECT switch operation
1. Preparing the operation tools
Set the PROTECT switch knob by using the tip of a pair of tweezers, a
precision screwdriver, or a tool with a tip width of approx. 0.8mm (0.04").
Do not use objects with round tips, as the round tip can easily slip off the
switch knob, possibly resulting in an incorrect setting.
2. Switch operation procedure
As shown in the figure below, the switch knob can be "pushed" or "pulled". When setting the switch, do not set
it in an intermediate position.
3. Precautions when setting and using the switch
• Leaving the switch knob at an intermediate position for an extended period can cause an equipment
failure.
• Also use care to avoid scratching the PCB when setting the switch.
