	Test your UPS's battery charge**
	With your connected equipment and your UPS turned ON, move
	this switch to the left; hold it there for 2 seconds and release it. The
	UPS will beep and flash its LEDs as it momentarily switches to
	battery to test its charge. If the UPS alarm sounds afterwards, or
	the properly-sized load is not supported, let your UPS charge its
	batteries for 12 hours and repeat the test. If alarm still sounds,
	contact Tripp Lite for service. CAUTION: Do not unplug your UPS to
	test its batteries. This will remove safe electrical grounding and
	may introduce a damaging surge into your network connections.
	**If your model is not equipped with this switch, you can still test your UPS batteries. First plug your UPS
	into a grounded surge suppressor (which will maintain the ground connection), then turn the surge
	suppressor's power switch OFF.
	Cold-Start your UPS
	If your UPS is equipped with a MUTE/TEST switch, you may “cold
	start” it and use it as a stand-alone power source when utility
	power is not present, providing that the UPS's battery is charged.
	To “cold start” your UPS, first turn the "OFF/ON" switch ON.
	Then, move the MUTE/TEST switch to the left, hold momentarily

4and release when the "" indicator light begins to flash.
