About power supply voltage
In addition to the "BATT" indicator, the FR-2 provides the error tone function
which warns you when the battery power drops down.
This function generates the error tone from the internal monitor speaker (or from
headphone output) when the battery power voltage drops down to the specific
level. You can make the error tone output setting from the "Errot Tone" menu
item on the "Setup" menu in the "MENU mode". See "Setting error tone output
condition" on page 87.
<Notes>
• Supplying excessive voltage may damage the unit. Never supply voltage which
exceeds the regular voltage.
• If batteries are completely exhausted or the power supply section has a trouble by
surge current, etc., the protection circuit works and the power is shut off. In such a
case, set the [POWER] switch to "OFF", replace batteries with new (or fully-charged)
ones, then set the [POWER] switch to "ON" again.
If the FR-2 does not return to the normal condition after carrying out the procedure
above, there may be some trouble inside the circuit. In such a case, consult your local
Fostex dealer or service station.
• Never turns off the power when the [ACCESS] indicator flashes. Data currently being
recorded or played back may be damaged.
Battery capacity is sufficient.
Battery capacity is almost half.
You should replace batteries.
<Note>: If you continue to use the FR-2 after the "BATT" indi-
cator gets shorter and batteries are exhausted, the display shows
the warning message as shown right, and the FR-2 automati-
cally shuts down. When operating the FR-2 on batteries, you
should always pay attention to the battery power condition.
While operating the FR-2 on the AC adaptor, the indicator always fully lights up.
While operating the FR-2 on batteries, the length of the "BATT" indicator changes
according to the battery condition (the lower battery power voltage, the shorter
"BATT" indicator). Pay attention to the indicator when you operate the FR-2 on
batteries, and replace batteries at the appropriate timing.
See the next page for details about power voltage.
You can turn on the backlight of the display, as well as adjusting the display con-
trast. See "Setting the display backlight/contrast" on page 22 for details.
When the FR-2 operates on batteries, you can check the battery condition via the
"BATT" indicator.
When the battery voltage gets lower, the lighting area of the "BATT" indicator
becomes shorter. The battery life depends on batteries, however, you can roughly
know the current battery condition via the indicator (when operating the unit on
the AC adaptor, the indicator always fully lights).
