Battery Charger
The battery charger is especially designed to charge the internal custom NiMH battery pack
that powers the Rex transmitter. It will typically charge a fully discharged battery in under 4
hours, and it has smart safety features to monitor the charge process. It is recommended to
first charge the batteries for at least 4 hours before the initial use. The power jack or line cord
should be accessible while charging for quick disconnect, if necessary.
The charger is built into the unit, and the AC/DC power supply plugs directly into the
transmitter. The power supply is universal and will accept any AC input voltage in the 100 -
240 volt range, 50 or 60 Hz. A variety of power line cords are available to accommodate
different style plugs around the world.
For in-vehicle charging, plug the AC/DC power supply into one of the many commercially
available vehicle DC-to-AC inverters capable of supplying at least 100 W of power.
The transmitter detects when the charger is plugged in, and it will automatically go into
battery charging mode. To protect the battery from an extremely deep discharge, the
transmitter will also turn itself off when the battery voltage has reached a critically low level and
the charger IS NOT plugged in.
When the Rex transmitter detects that the battery charger is plugged in while the
power is turned ON, it will display “CHA” on the LCD and the bars inside the
battery indicator will “roll”.
When the battery is fully charged, it will display “FUL” on the LCD.
If the power is OFF, the battery will still charge, but no indication of charging activity or
battery status will be shown on the LCD.
If the battery charger is not charging the battery successfully, the letters “Err” will be
shown on the LCD.
The battery may not successfully charge for a number of reasons: the battery may be
overcharged, the battery may not be taking a charge in a reasonable amount of time, the
battery may be too warm to be charged without causing damage to its internal cells, or the
battery charger may have an internal fault.
If the error message comes on, take the following steps to try to clear the condition:
