Steps
CAUTION
After the AMX−4+ charges to 100% (i.e. CHARGE COMPLETE" ), the capacity
gauge will remain stuck−at−full" for a pre−programmed amount of usage before
the number of lit segments begins to decrease. This usage is equivalent to approxi-
mately 10 minutes of drive or 100 minutes of idle. Once this stuck−at−full" capacity
is used, the capacity gauge will update according to Table 1.
When the AMX−4+ capacity gauge drops to 0%, inhibiting x−ray exposures, it is
possible to access some emergency capacity to finish an exam by turning the
AMX−4+ off and then back on. After it has completed its power−up tests, the
AMX−4+ will provide enough capacity for approximately 45 seconds of usage before
x−ray exposures are again inhibited.
In some cases the AMX−4+ battery may not provide sufficient voltage for
proper operation when EMERGENCY CAPACITY is used. Therefore this
feature should only be used when absolutely necessary.
To insure the greatest reliability, you may decide to establish a battery charging sched-
ule at your particular site, based on past experience and anticipated needs.
Follow these steps to recharge the batteries.
When recharging the batteries, always locate the unit in a well ventilated
area.
1. Drive the AMX−4+ to a designated battery charging station or to a correctly
rated wall outlet. A rating plate is located on the front of the unit, above the bat-
tery plug. (See Illustration 6−3.) Position the unit to within 10 feet of the outlet.
2. To plug in, firmly grip the plug located on the front of the unit, and pull the re-
tractable cord straight out until it is fully extended. Set the cord by a slow pull-re-
lease action. Plug into the battery charging station.
