Back-UPS BE650G2-RS/BE850G2-RS10
Voltage Sensitivity Adjustment (Optional)
The Back-UPS will switch to battery power if the utility input voltage level or
distortions go out of range or if the utility power is experiencing voltage
fluctuations, to protect connected equipment. In situations where either the
Back-UPS or the connected equipment is too sensitive for the utility input
voltage level, it is necessary to adjust the transfer voltage.
1. Turn off the Back-UPS while connected to a wall outlet.
2. Press and hold the POWER ON/OFF button for 10 seconds. The
Power On/Off LED will alternate green and red to indicate that the
Back-UPS is in Program mode.
3. The Power On/Off LED will flash either green, amber, or red to indicate
the current sensitivity level. Refer to the table below for an explanation
of the transfer voltage sensitivity levels.
4. To exit Program mode wait five seconds and all LED indicators will turn
off. Program mode is no longer active.
