RECOMMENDATIONS FOR BATTERY USE

Ni-MH and Ni-Cd batteries are subject to “memory effect,” wherein the battery looses its energy capacity if being charged after not being fully discharged.

It is not recommended to charge the battery before it is completely discharged.

If the battery capacity has already reduced, it is possible to restore its capacity partially by means of battery training.

It takes approximately 3 hours to fully charge the battery.

BATTERY TRAINING

A soon as the battery state of charge reaches its critically low level ( ), the devise goes into an accelerated discharge mode that lasts approximately 2 hours.

After the accelerated discharge mode is completed the battery must be charged fully.

Charging/discharging cycles should be repeated 3-5 times.

LOCKING AND UNLOCKING THE RECORDER

To avoid accidental button pressing that can lead to changes in settings, it is possible to lock the buttons of the recorder.

LOCKING THE RECORDER

To lock the recorder press and hold buttons and on the front panel of the re-

corder simultaneously for at least 3 seconds.

A red lock icon should appear in the bottom of the screen.

The recorder can be only locked via the main window.

Locking does not influence the work of the recording control switch.

UNLOCKING THE RECORDER

To unlock the recorder press and hold, press and hold buttons and on the

front panel of the recorder simultaneously for at least 3 seconds.

DISPLAY STATUS INDICATORS

RECORDING

Before recording, verify that audio signal sources, batteries and memory card are connected.

To start recording, do the following:

Switch the voice recorder on, as shown on p. 13.

To turn on Record mode, slide the Activation switch to the position.

Recording duration (length) and filename will appear in the display.

If headphones are connected to the voice recorder, you can listen to current recording.

To do this, press the

button to turn on the end-to-end channel.

The headphone indicator will change from to , and the current

recording will be reproduced in the headphones.

To stop recording, slide the switch to the position.

Switch the voice recorder off, as shown on p. 13.

Removing the memory card while recording may result in complete data loss.

If Voice Activity mode is on, which threshold level is too high (see p. 18), the switch cannot be

used to start recording. Set threshold value of Voice Activity mode taking into consideration

the level of signal recorded (see p. 34).

When control buttons are not touched, the screen reverts to energy-saving mode, i.e. it turns

black.

Touch any button on the front panel to re-activate the screen.

When recording is done using rechargeable batteries, files may be incorrectly opened or played

by the Windows operating system. In such cases, the removable disk containing these recordings should be checked with the CHKDSK utility (Check Disk utility) included in Windows XP and Windows 7 OS standard software.

FILE NAMES

The voice recorder has two file name formats:

Normal format: “G_:” prefix and six digits.

The prefix is the same for all files, so it does not appear in the Next №: line. You can only select this format. You cannot change its value.

Normal file names are automatically formed by adding 1 to every new file name.

2. Special format: eight digits. These can be changed by the user.

The special format allows users to record over existing files without changing the original file names until there is enough space (maximum 2 GB for WAV-files)

. If there is not enough space within the file, the voice recorder will create automatically new file with normal name format (see above) and will continue recording.

While recording over existing files, the voice recorder will set the parameters, specific for these

files.

Selecting file name format

To change the file name format, do the following:

Press Enter ( ) once.

The Settings menu will appear on the display.

Use the up-down arrow buttons, and , to select menu items.

Connect the recorder to a free USB slot on the computer.

Accumulator charging

The

USB connected

message will appear on the screen

To start a short-time charging, press .

After pressing the recorder will be disconnected from the USB interface as an external device but will remain connected to

power supply and will use USB slot as an accumulator charger.

The screen of the recorder will look as one described on the

page

Ошибка! Закладка не определена. в подразделе Ошибка!

Источник ссылки не найден..

Disconnecting the recorder from the USB interface without pressing will stop the charging of the accumulator.

To avoid malfunction, make sure the accumulator is inserted in the battery chamber before charging.

If battery as a type of power supply Power supply battery is chosen, being connected to computer USB slot or charger, the recorder will not be charging.

Changing the type of power supply to Power supply accum and connecting the recorder to computer USB slot the charging of the device will not start.

To start the charging process, connect the recorder to computer USB slot once again or turn the device off and then on.

It is not recommended to charge the recorder partially connecting it to computer USB slot as the accumulator is subject to “memory effect,” wherein the accumulator loses its energy capacity if being charged after not being fully discharged.

Charging accumulator if recorder is turned off

If the recorder is turned off and connected to a computer USB slot or charger and the

accumulator is chosen as a power supply type, the charging process will be indicated with animated picture on the screen of the recorder.

When the device is fully charged the indicator will change its colour from yellow (the accumulator is charging) to green (accumulator is full).

USB-MICROPHONE MODE

Before using the recorder as a USB microphone switch the slider to on the side panel of the re-

corder.

The data will be saved to computer memory, not to internal storage of the recorder.

Connect the recorder to a computer USB slot with USB cable.
