Reducing Battery Power Consumption - Fostex FR-2 Owner's Manual

2) Insert eight AA-type batteries.
Make sure that the batteries are the right way round (+ and -), as shown below.
<Warning!>: Wipe terminals of the battery compartment and batteries with a dry cloth
on occasion. If terminals are dirty, the voltage supplied to the unit may drop down.
3) Fit the compartment cover as it was before.
Be sure to fasten the screw tightly so that the compartment cover never drops while using
the FR-2.
<Warning!>: Used batteries should be disposed following to your local regulations to
avoid problems of environmental pollution.
The chart below shows the expected battery life of continuous operation by type.
Note that it depends on the circumstance the FR-2 is used (temperature, humidity,
the number of recordings) and battery manufacturers, therefore, use the chart
just for your reference.
The FR-2 can indicate remaining battery life, as well as can generate the error tone
when the power voltage drops down to the specific level. When you use batteries
for operating the FR-2, you should also read "About power voltage" described on
page 21.
• Reducing the battery power consumption
For reducing battery power consumption to extend the battery life, when the
internal monitor speaker is disengaged (i.e. when a headphones plug is inserted to
the [PHONES] jack), no power is supplied to the internal amplifier which is used
for driving the internal speaker.
You can also reduce power consumption by the following tips.
The lower the input impedance of a device connected to the FR-2's output
•
connectors, the less battery power the FR-2 consumes.
The lower the output level of headphones or internal monitor speaker, the
•
less power consumption.
If you do not use the FR-2 for a long period of time, you should remove
•
batteries (when batteries are inserted, the FR-2 consumes little power even
though the [POWER] switch is set to "OFF").
