Battery Pack Replacement
1. The
IQ
uses rechargeable NiCad batteries. NOTE: Batteries do NOT
need to be fully discharged. Tobias has run the batteries on a
conditioner prior to shipment. (See Step 8 below). Fourteen hours are
required to fully charge the unit.
2. Repeated undercharges will damage the battery pack. If the unit was
charged overnight and the readout still displays a "LOW BATTERY"
message, the replacement of the NiCad battery pack (Part #A1496) is
necessary.
3. Close and latch the unit shut and wait for the unit to turn off.
4. Turn the unit over and remove the two Phillips head screws in the front
of the unit and the two black Phillips head screws on the rear panel.
5. Carefully separate the halves of the case. These are connected by a thin
ribbon cable. Use extreme care not to damage the cable when
separating the two halves.
6. Remove the screws holding the battery plate in place and unplug the
two connectors. Replace the old battery pack (Tobias part #A1496)
with
the new one, replace the screws and reconnect the connectors.
7. Place the two halves of the unit back together being careful not to pinch
the ribbon cable. Replace the four Phillips head screws.
8. LOW BATTERY messages occur in TWO stages. The first stage, or
early, ‘Low Battery’ messages appear briefly on the upper part of the
display and are easy to miss; however, if you see one, that is the time to
take the unit out of service and recharge it. The second or final ‘Low
Battery’ message is in the center of the display --- the unit will then
turn off, and attempts to turn it back on can fail.
