5.4 Power supply
5.4.1 Gnome-P battery
The voice recorder is powered by an integrated Li-ion battery (750-900 mAh) used in GSM phones Nokia.
Power consumption in active mode is 25-30 mA, in Voice Activation mode (with input amplifiers and VA
amplifier enabled) – 3 mA. Minimum power consumption (1 mA) is achieved in timer- and switch-activated
recording. This mode of operation is also maintained when battery voltage drops below the critical value.
5.4.2 Battery charge rules
Gnome-P battery is charged from an external power source (AC/DC charger with USB jack). If
Gnome-P is connected to both USB and external power source, the voice recorder will be charged from an
external source, while the USB controller will be USB-powered. Maximum battery charge current is 300 mA;
full charge may take up to 4 hours.
The red LED (6 in Figure 1) will light up and remain on continuously until the battery is fully charged.
After that the charge process will automatically terminate and the LED indicator will switch off.
Attention!
Before switching on the voice recorder for the first time after purchase or after voice recorder being not in use
for an extended period of time, charging of the built-in battery during not less than 5 hours is required. For
the first 20 minutes, LED indicator may not light up, and PC may not detect the voice recorder.
In this case, you should wait for 20 minutes, then, if the indicator does not light up, disconnect and connect
again power supply. This can be repeated up to three times. If, nevertheless, the LED indicator still does not
light up, contact with technical support.
Attention!
To prevent battery failure due to over-discharging, follow these rules:
– If the voice recorder is out of use for an extended period of time, top up charge the battery at least
once every four weeks.
– Recharge the battery after each recording session.
5.5 Flash memory
Audio data is written to and stored in an integrated nonvolatile 8 GB NAND flash memory. Even if the
voice recorder is not powered, all data is stored in its flash memory for up to 10 years.
All recordings can be erased from the voice recorder memory either manually or by means of the
Sound Manager Gnome-P software (see 6.4).
