Back-UPS BVN650M1, BVN650M1-CA, BVN900M1, BVN900M1-CA
Voltage Sensitivity Adjustment
The Back-UPS detects and reacts to line voltage distortions by transferring to battery
backup power to protect connected equipment. In situations where either the Back-
UPS or the connected equipment is too sensitive for the input voltage level it is
necessary to adjust the transfer voltage.
1. Turn off the UPS while connected to a wall outlet.
2. Press and hold the ON/OFF button for 10 seconds. The POWER button will alternate
green- red to indicate that the Back-UPS is in Program mode.
3. The POWER button will flash either green, amber, or red to indicate the current
sensitivity level. Refer to the table for an explanation of the transfer voltage sensitivity
levels.
4. To exit Program mode wait five seconds and all LED indicators will extinguish.
Program mode is no longer active.
