Base Charge Mode - Hand Held Products 4820 User Manual

Base Charge Mode

In order for the battery to be charged, there must be enough voltage for the
circuitry to work. There are three methods during which power can be supplied
to the base:
1: 9VDC power supply connected to the barrel connector
2: 12VDC host power source only
3: 5VDC host power source only
The chart below describes each selection by condition.

Using a slow charge rate draws less current (power) from the input power source
when the battery is mostly discharged.
Note: If you attach the 4820/4820i system to a host with a 12V power source,
the 12V host is dominant; the system pulls power from the host and not
the 9V power supply. For example, if you have a host system with a 12
volt available to the base, it will supersede the 9V power supply. The 9V
supply is not needed for 12V host applications and only serves as a
backup if the system goes down.
Scan the appropriate bar code for your application. Default = Automatic .
