Optional External UPS Backup Power
An optional external 12V UPS power backup device is available with a
special cable designed to connect to the MT8733. This external UPS power is
for Telephone service only, when AC power is lost. The MT8733 does not
ship with this external 12V UPS power backup device, it is sold separately
and is NOT required for normal operation with AC power using the included
power adapter. If you lose AC power, the UPS power back-up device will
allow your telephone service to still function on Line 1 for a number of hours,
but note that your WiFi and Internet service will not be available during that
time. If you want this UPS power backup device, you can purchase one
online.
The type of external UPS power backup device that can be used with this
product is Model XXXX from MTRLC LLC.
Note that in the case of loss of power, the Tel1 jack will provide up to five
hours of talk time or eight hours of stand-by time if you have the optional
UPS (additional booster packs can be added to the external UPS to increase
the backup time to up to fifteen hours of talk time or twenty-four hours of
stand-by time). The Tel2 jack does not provide this back-up feature. Only
phones that do not require their own power source will work during a power
outage (unless the phones are provided with their own separate battery back-
up system). It’s a good idea to have at least one phone available that just
needs to plug into the MT8733, and not into a separate power jack.
