Rechargeable batteries
Read the information below carefully when
using a nickel-metal hydride rechargeable
battery (model BR404).
4 Discharging
Rechargeable batteries discharge naturally
when not in use. Be sure to charge the
battery before use.
4 Operating temperature
Rechargeable batteries are chemical-based
products. Their performance can vary
even when used within the recommended
operating temperature range. This variation
is normal.
4 Recommended temperature
ranges
When powering voice recorder: 0 to 42°C
(32 to 107.6°F)
When being charged: 5 to 35°C (41 to 95°F)
During long-term storage: -20 to 30°C (-4
to 86°F)
Use of a rechargeable battery outside the
temperature ranges above may result in
drops in battery performance or life. When
not using the voice recorder for an extended
period, remove the rechargeable battery
before storage to prevent fluid leakage or
rust.
NOTE
• Due to the nature of nickel-metal
hydride rechargeable batteries, new
batteries and batteries not used for an
extended period (one month or more)
may not charge completely. The battery
should become fully charged after
charging and discharging the battery
up to three times.
• Always dispose rechargeable batteries
in the legally prescribed manner. Before
disposing rechargeable batteries that
are not fully discharged, take steps to
prevent shorting such as insulating
their terminals with tape.
Battery indicator
As the battery loses its remaining charge, the
battery indicator on the display changes as
follows:
• [ ] indicates there is little remaining
battery charge. Charge the battery or
replace it with a fresh one. When the
battery has run out, [
] and [Battery
low] appear, and operation stops.
