Basic operation 1. Before Using the MR-2 Inserting or Replacing Batteries The MR‐2 requires two AA‐size batteries. We recom‐ mend that you use nickel‐metal hydride batteries, but you may also use alkaline batteries (LR6). Serial number The performance of alkaline batteries differs signif‐ icantly between manufacturers. To ensure that the MR‐2 operates in a stable manner, please use bat‐ teries from a reputable manufacturer (see page 58).
If the battery charge is getting low, you can supply USB bus power to the recorder using a USB cable to continue operating the recorder without any power interruption. Before you disconnect a recorder that is running on USB bus power, turn off the power to the recorder first, then remove the USB cable. If the recorder is switched to the battery operation while the recorder’s power is on, the recorder may be reset or turned off if the battery charge gets too low.
About the available recording tim Available recording time per card varies with the recording format setting (see page 14). The following table shows the approximate recording time available in each format per 1GB of memory card capacity. Format Recordable time Format Recordable time MP2 48kHz/192kbps 660 minutes 25 minutes MP3 44.1kHz/192kbps 600 minutes WAV 96kHz/24bit WAV 176.4kHz/24bit 15 minutes WAV 44.1kHz/16bit 90 minutes WAV 192kHz/24bit 13 minutes WAV 44.
4. The meter/counter screen When you turn on the power, the meter/counter screen is shown in the display. When the menu list (MENU) screen is shown, you can also access the meter/counter screen by pressing the menu button. This screen shows information such as the MR‐2’s operating status and recording/playback format.
Repeat indicator This icon appears when you program repeat playback. No indicator appears here if repeat playback is not programmed (see page 35). Recorder status The current status of the recorder is shown using symbols such as record ( ), play ( ), or stop ( ). Project/file playback position indicator This bar graph indicates the approximate playback position of the current counter value in relation to the overall length of the current project/file.
Remaining battery charge/USB bus power indicator This icon indicates the remaining battery charge. If the MR‐2 is powered via USB bus, the “ ” icon will appear instead. Sufficient charge If “ Low charge ”, the batteries are almost exhausted. Replace them immediately. 5. Recording When you record on the MR‐2, date and time information is automati‐ cally added to the file so that you can manage your projects more easily.
Mounting the recorder using the camera tripod The MR‐2 features two 1/4‐inch threaded sockets that enable you to mount the unit on a camera tripod. These sockets are located on the bottom panel and rear panel respectively. Using the tripod makes it easy to set up the recorder in a position suitable for recording.
About automatic input source detection The MR‐02 automatically scans to determine whether or not the MIC IN or LINE IN jack is connected. If the unit detects a connected jack, it will automatically assign the jack as the input source. Therefore, do not con‐ nect anything to jacks other than the one you want to use for audio input. If multiple jacks are connected to external devices, the unit will select a jack according to the following input priority list.
