Remote Sensor Bars:
2 x 15pin D-sub jacks are located on the side of the unit for plugging in 1 or
2 additional sensor bars by using remote cables up to 200 feet (61m). The
top sensor bar can also be remote with a cable.
Power Options:
9V alkaline, 7.2V NiMH rechargeable pack (charged in the unit), or AC
adapter wall power cube (AC adaptor will operate the unit or recharge the
NiMH battery pack)
Battery Life:
9V alkaline: 140 hours
Rechargeable Nickel Metal Hydride: 300 hours
(Adding additional sensor bars to the QUESTemp
°36 reduces battery life.)
