The lights are clear: green is OK. Red: battery failure. Do not forget to connect the battery before connecting the electrical box (see the yellow band)
A specific switch to activate or deactivate the Master function. For me it is useless this button is off.
A reset button is located on the side.
Can connect to the arrival of an ADSL / PSTN RJ11 cable on the case.
Another box will power your phone or RTC.
A connector used to communicate with your computer and have follow-up information and you can set the sensitivity of tensions. On this point, it is less accurate than the BR1500G-EN-FR models BR900G. On the FR-BE700G the threshold is at 196 volts and 256 volts to the ceiling, so less accurate but sufficient in most cases. If, against your installation is old, take one of the two models listed above. All models can be configured to set up audible alarms to be notified of the case (e). The advantage of BR1500G-EN-FR models BR900G is permanently display the voltage via a display.
The battery on this model is supposed to last 3 years. This is theoretical if the purpose is to protect "in case" you can double this duration widely.
If you often against by power outages must be provided to change but the light will tell you in passing red "replace battery"
I own the previous model to BR1500G-FR, the APC Back-UPS RS model 1500, which is perfectly quiet, a fan switches on in case of battery operation which is rare. However, I install Amp, LCD TV, DVD player, TV box, box adsl, telephone, mobile phone and charger. There are two battery coupled Siamese and they still have not been changed after 6 years of use. When there are storms I am under no concern. In case of power failure my ADSL phone line is still available, which would be the case without inverter!
I recommend APC (acquired by Schneider Electric). If your product seems reconditioned, report it to Amazon.com through your account, you will be replaced free of charge.
If the product or other sizzles, contact your service from Amazon that will tell you what to do especially if the product is under warranty.
The product is however improvable, missing lights to better understand what is happening! The continuous or discontinuous beeps are not clear to understand especially when you work with other small beep / noise environments.
