e7w Battery related Issues

A Battery symbol has appeared in the lower right corner of the e7w display in one or more rooms

F
The e7w displays the battery symbol when it has detected the voltage of the installed 4 AA batteries has
dropped below 4 VDC. Replace the batteries in the e7w with 4 new alkaline AA batteries. The low battery
alarm should clear within 1-2 minutes after replacing the batteries.
The actual battery voltage can be read from the e7w by entering Service Parameter mode and going to the
bAu parameter and viewing the displayed value. Refer to Appendix 6 of this document for details.
The value is 0 to 6 VDC scaled between 0 and 255. Take the displayed value, divide by 255 and multiply by 6
to get the voltage. A displayed value of 255 indicates 6VDC. A displayed value if 170 indicates 4 VDC
Note: Future versions of the e7w will display its battery voltage in a more user friendly fashion.
In addition to the Low Battery symbol appearing on the e7w display, if the hotel has an Inncom network
installed with an Inncom Server running INNControl 3 or INNControl 5, the room should appear in any
generated Low Battery reports and a "Device with Low Battery" indication should appear for the room in
IC3/IC5.
