Additional Functions
In addition to the main menu system, there are several other
functions that are featured by the VTG. A low battery warning
message and a button lock mode that locks out all front panel
buttons except the power button are also featured.
Low Battery mode
When the batteries in the VTG are low and the external power
supply is not connected, the message “Warning: Battery Low!”
flashes on the LCD for one second every 30 seconds. To end
this cycle, the external power supply needs to be connected or
the batteries need to be recharged or replaced. See Installing the
VTG 300 Batteries in this chapter.
