Maintaining Battery Life
You can recharge the internal rechargeable batteries at any point. If
the Battery Status Indicator turns red, you should recharge at your earli-
est convenience. Plug in the 120V AC / 9V DC power adapter shipped
with the 3e-250 and charge fully (may require up to 3 hours). Recharging
should be done in conditions of less than 113 ° F (45 ° C) to ensure proper
charge.
There is an RS-232 Trickle-Charge on-off switch on the back of the
3e-250 which is provided as a discretionary battery power conserva-
tion device. The default position is OFF. And this switch should be left
in the off position if you are running the device connected to any piece
of test equipment that runs on battery power, as it will "steal" the power
from the parent device in order to "trickle-charge" the 3e-250 battery.
However, if you are running the 3e-250 on a host device that can spare
power, you can conserve battery power extensively by setting the RS-
232 Trickle-power switch to on. When the 3e-250 is charging from an AC
power outlet, the switch can be either on or off. It does not matter. See the
picture of the back of the device on the preceding page for the location of
the Trickle-Charge switch. Move the switch with a small point object like
a paper clip or pen point.
