The vehicle dock and associated electrical wiring should be installed under
the supervision of properly trained and qualified personnel. Follow these
installation instructions closely to ensure safe, reliable performance of the
Model 6600 Hand-Held Computer and any peripheral devices (such as a
printer) that may also be installed in the vehicle.
The vehicle electrical system must be in excellent condition. This means
the charging circuit must work properly and that vehicle-generated electrical
"noise" must be minimized and within specifications.
The charging circuit must neither undercharge nor overcharge the vehicle
battery. Either fault condition in the vehicle electrical system can cause a
no-charge condition in the computer battery, and printer battery too, if one is
installed in the vehicle. In general, the vehicle battery voltage should read
approximately 13.0 V dc with the engine off, and should rise slightly with
the motor running.
Excess electrical noise can be severe enough to defeat the electrical filtering
that is built into printers and computers made by Norand Corporation. De-
fective ignition wiring, damaged insulation, or a faulty vehicle electrical
component can cause electrical noise. When this happens, computer and
printers can behave unpredictably.
The gray battery cable (NPN: 206-953-009 or 216-964-009) must be con-
nected in strict accordance with the instructions in this manual.
