Recharging the VTG 300R

Prior to using the VTG 300R for the first time, please be
sure that the batteries are fully charged. The VTG 300R
batteries are not covered under Extron’s three year
warranty.

A fully discharged VTG 300R may take up to eight hours to
reach the fully charged state. The charging process will
automatically end after the batteries are fully charged or after
eight hours have elapsed, whichever occurs first

Once fully charged, the VTG 300R may operate for up to five
hours of normal use.

Although the VTG 300R may operate with the charger still
actively powered and connected to the unit, the built-in batteries
will have a longer life if the charger is used to fully charge the
VTG 300R whenever the VTG 300R is powered off.

The amber charge status LED on the side of the VTG 300R will:

• blink steadily when the unit is fully charged.

• light steadily while the unit is being charged.

• not light if there is no input power to the charging

circuit.

During the recharging process, a faint buzzing sound
may be heard from the VTG 300R and/or the power
supply. This is a normal occurrence and should be no
cause for concern.

The VTG 300R charging circuit features short circuit
protection. If a short occurs, a heat sensitive thermal
fuse will cause an open circuit and prevent damage to
the charging system.

When the batteries become fully charged or the charging
time exceeds eight hours, the charging process will
automatically end.

During the recharging process, the VTG 300R case
should never feel so hot to the touch such that it
cannot be held. Should this unlikely event occur,
please discontinue the recharging process and
contact your Extron representative.
