3. Startup of the REA ScanCheck 3n
Special installation on the REA ScanCheck 3n is no longer required. It is delivered ready to operate.
The unit is configured for a standard presetting and can inspect and evaluate most code types
according to the GS1 standard requirements immediately after activation.
The four NiMH batteries provided have an especially low discharge rate.
They are already installed in the battery compartment before delivery.
It is also possible to use 4 Mignon primary batteries instead of the 4 batteries.
In the case of heavily discharged batteries and no power supply
connection, the REA ScanCheck 3n can be activated briefly after
startup. The activation process is interrupted and the unit shows no
further response. In this case, the batteries are probably empty or
even incorrectly installed.
There is continuous monitoring of battery voltage during operation
with rechargeable (or non-rechargeable) batteries.
When the voltage reaches a critical threshold, an electronically
monitored charging process is started or completed.
If the operating voltage value sinks below a critical threshold, the unit
outputs a corresponding warning message and ends the operating
program, saving the settings.
Attention:
If the REA ScanCheck 3n is operated by non-rechargeable batteries instead of rechargeable
batteries, the power supply must never be connected. Connection of the power supply will lead
to destruction of the batteries and, with a high degree of probability, to the destruction of the
unit as well.
Any manufacturer's warranty is thereby voided.
When the PoE power charger is correctly connected, the recharging of the rechargeable batteries
takes place automatically and is monitored electronically (see also Chapter 3.4.1). Over-charging or
over-heating is monitored and prevented by corresponding protection circuits.
If the unit is operated during the charging process, the complete charging of the rechargeable batteries
will take correspondingly longer than it would with the unit deactivated.
The unit also operates properly if no rechargeable batteries are installed, only one cell is missing but
the power supply is correctly connected and connected to the mains voltage.
Upon removal of the connection cable, however, all programs will immediately end without saving data
or settings and without pre-warning.
If the rechargeable batteries are heavily discharged, there is risk that the rechargeable batteries will not
be recognized by the charging circuit (charging LED remains off). In this case, the rechargeable
batteries must be replaced. In some cases, the rechargeable batteries can be reactivated by an
external charger with single-cell charging.
