remains in a standby mode. Users can resume taking
measurements immediately by pressing the power button.
• Press [F3] to cancel the command and return the PT878GC to
normal operation.
If the PT878GC locks up, you can reset it by holding the power
key (the red key in the upper right corner) for 15 seconds.
